With the development of Internet of Things (IoT) technology and image processing technology, cameras are widely used in a variety of security monitoring systems. The video recording of monitored areas by the cameras is a core component of the security monitoring systems, which not only provides real-time monitoring and post-event investigation capabilities but also offers deeper support for security management through intelligent analysis.

However, since an external stable power supply is required to continuously supply an operating power to the long-powered camera during its operation, there is a high requirement for an external environment, which makes it impossible to use such a camera in some occasions. In a case where a stable power supply cannot be provided, a camera equipped with a battery is generally used, and the battery is used to provide an operating power supply for the camera.

Exemplary embodiments of the present application will be described in more detail below referring to the accompanying drawings. While the drawings show exemplary embodiments of the present application, the present application may be embodied in various forms and should not be construed as limited to the embodiments set forth herein.
In an embodiment of the present application, the camera 1 and the electronic device 2 may each include one or more processors, which may be a central processing unit CPU, or an Application Specific Integrated Circuit (ASIC), or one or more integrated circuits configured to implement the embodiment, which is not limited herein. The electronic device may include one or more processors, which may be of the same type, such as one or more CPUs; it may also be a different type of processor, such as one or more CPUs and one or more ASICs, which is not limited herein.
In the embodiment of the present application, the camera 1 is installed in an area to be monitored (e.g., home, office, shopping mall, etc.), so that the camera 1 can continuously take a monitoring video recording in the monitored area and transmit the captured video recording to the electronic device 2 of the terminal via the network 3 for the user to browse.
The processor 11 is configured to execute a computer program 13, and specifically can execute relevant steps in the embodiment of the method for prolonging battery usage life of a camera provided in the present application. Specifically, the computer program 13 may include a plurality of computer-executable instructions.
The processor 11 may be a central processing unit CPU, or an Application Specific Integrated Circuit (ASIC), or one or more integrated circuits configured to implement the embodiments of the present application. The camera 1 may include one or more processors, which may be of the same type, such as one or more CPUs; it may also be a different type of processor, such as one or more CPUs and one or more ASICS.
The memory 12 is coupled to the at least one processor 11 and configured to store the computer program 13. The memory 12 may include high-speed RAM memory, and may also include non-volatile memory, such as at least one disk memory.
In the embodiment of the present application, the camera 1 further includes a battery 14, an image capture unit 15, a fill light 16, a sensing unit 17, and an artificial intelligence (AI) detection unit 18. The processor 11 acquires a current electric quantity value S of the camera 1 from the battery 14 and acquires the detection results of the sensing unit 17 by executing the processes in the embodiment of the method for prolonging battery usage life of a camera described below, and controls the camera 1 to operate in a camera shooting mode corresponding to the current electric quantity value S, for example, to control the video recording frame rate of the image capture unit 15 and the luminous power of the fill light 16, or to control the image capture unit 15 and the fill light 16 to stop operating so as to enter the standby state. The processor 11 also controls the turning on and off the AI detection unit in dependence on the current electric quantity value S.
The image capture unit 15 is configured to record video images of the monitored area. The maximum video recording frame rate of the image capture unit 15 is Fmax, i.e., the number of image frames acquired by the image capture unit 15 per second. It will be appreciated that the greater the video recording frame rate of the image capture unit 15, the greater the power consumption of the image capture unit 15.
The fill light 16 is configured to enhance illumination intensity of the monitored area so as to improve the effect of the image capture unit 15 in recording video data of the monitored area. The maximum luminous power of the fill light 16 is Wmax. The greater the luminous power of the fill light 16, the more power consumption will be when the fill light 16 is operated. The fill light 16 may be an infrared lamp, a white light lamp, an LED fill light, a stroboscopic fill light, etc. The infrared lamp is mainly used for nighttime or extremely poor light environment, providing invisible infrared light so that the image capture unit 15 captures an image. The white light lamp is used to provide visible light so that a color image capture unit can capture a color image in a low light environment or at night.
The sensing unit 17 is referred to as a sensor unit capable of sensing infrared radiation, such as a Passive Infrared (PIR) unit. If a human body enters the monitored area, the sensing unit 17 may sense an infrared heat source radiated from the human body.
The AI detection unit 18, using in-depth learning and computer vision techniques to analyze the images acquired by the image capture unit 15 and the recorded video data, is capable of automatically identifying objects, behaviors and scenes, such as identifying intruding targets in the monitored area.
In step 110, acquiring a current electric quantity value S of the camera 1.
The current electric quantity value S refers to the remaining electric quantity value of the camera 1 at the current time, and may be expressed as a proportion, that is, the proportion of the remaining electric quantity of the camera 1 at the current time to the total electric quantity when the battery is fully charged. Since the remaining electric quantity of the camera 1 is a main factor affecting the battery life time thereof, by acquiring the current electric quantity value S, a mode (i.e., an operation mode) adapted to the current electric quantity value S can be further determined for the camera 1, so as to improve the battery life time of the camera 1.
In step 120, determining a magnitude relationship between the current electric quantity value S and a first threshold S1, and the magnitude relationship between the current electric quantity value and a second threshold S2, wherein S2>S1>0.
If the current electric quantity value S is represented by the proportion, the first threshold S1 and the second threshold S2 are also represented by the proportion. The electric quantity is divided into three sections by S1 and S2, i.e., 0-S1 section, S1-S2 section and S2-100% section. If the current electric quantity value S falls within the interval 0-S1, it is indicated that the remaining electric quantity of the camera 1 is relatively small; if the current electric quantity value S falls within the interval [S1, S2], it is indicated that the remaining electric quantity of the camera 1 is at an intermediate level; if the current electric quantity value S falls within the interval [S2, 100%], it is indicated that there is more electric quantity remaining in the camera 1. The first threshold S1 and the second threshold S2 can be set as required, for example, the first threshold S1 is set to 10%, 20% or 35%, and the second threshold S2 is set to 55%, 65% or 70%. By determining the magnitude relationship between the electric quantity value S and the first threshold S1, and the magnitude relationship between the electric quantity value S and the second threshold S2, it is possible to know whether the electric quantity remaining in the camera 1 is small or large. The first threshold S1 and the second threshold S2 can be fixed values or adjustable values, and are set or adjusted by user-defined settings by the electronic device 2.
It is worth mentioning that if it is determined that S is less than or equal to S1, it is not necessary to continue to determine the magnitude relationship between S and S2. If it is determined that S is greater than or equal to S2, it is not necessary to continue to determine the magnitude relationship between S and S1.
In step 130, controlling the camera 1 to work in a camera shooting mode according to the magnitude relationship between the current electric quantity value S and the first threshold S1 and the second threshold S2. In the embodiment, the camera shooting mode includes high-electric quantity mode, a medium-electric quantity mode, and a low-electric quantity mode.
In step 140, when the electric quantity value S is greater than or equal to the second threshold S2, i.e., S≥S2, controlling the camera 1 to work in a high-electric quantity mod, and a power at which the camera 1 operates in the high-electric quantity mode to be a first power P1.
In step 150, when the electric quantity value S is greater than or equal to the first threshold S1 but is less than the second threshold S2, i.e., S1≤S≤S2, controlling the camera 1 to work in a medium-electric quantity mode, and a power at which the camera 1 operates in the medium-electric quantity mode to be a second power P2.
In step 160, when the electric quantity value S is less than the first threshold S1, i.e., S<S1, controlling the camera 1 to work in a low-electric quantity mode, and a power at which the camera 1 operates in the low-electric quantity mode to be a third power P3, wherein the first power P1 is greater than the second power P2, and the second power P2 is greater than the third power P3, i.e., P1>P2>P3.
In the same operation duration, the greater the power of the camera 1 is, the more power is consumed. The power of the camera 1 is the sum of the powers of the respective units in the camera 1. The main power consumption units in the camera 1 include an image capture unit 15, a fill light 16, a sensing unit 17, an AI detection unit 18, etc. Since the camera 1 works in different camera shooting modes, and the power of each unit in the camera 1 is determined by the operating state of each unit, the operating state of each unit in the camera 1 is also different in different camera shooting modes.
Since the operating state of each unit in the camera 1 is also different in different camera shooting modes, the camera 1 is controlled to work in the corresponding camera shooting mode according to the current electric quantity value S of the camera 1, and the operating state of each unit in the camera 1 is the operating state corresponding to the camera shooting mode.
In the embodiment of the present application, the camera 1 is controlled to work in the corresponding camera shooting mode according to a current electric quantity value S of the camera 1. If the current electric quantity value S belongs to different electric quantity intervals, the camera shooting modes corresponding to the electric quantity value S are also different, and when the camera is operated in different modes, the power consumption of the camera is also different. When the current electric quantity value S is small, the camera is operated in the camera shooting mode in which the power and the power consumption are also low, so that the battery usage life of the camera 1 is prolonged as compared with the case where the camera 1 is always operated in a single mode in which the power consumption is high.
In step 210, generating an intelligent video recording setting interface and displaying same on an electronic device 2, wherein the electronic device 2 is communicatively connected to a camera 1.
Here, for the convenience of describing the intelligent video recording setting interface displayed on the electronic device 2,
Before the user needs to control the intelligent video recording mode of the camera 1, the electronic device 2 establishes a communication connection with the camera 1 via the net operate 3, and the specific communication connection implementation method is not limited in this embodiment. After the electronic device 2 establishes the communication connection with the camera 1, the intelligent video recording setting interface 20 is displayed on the screen of the electronic device 2 for the user to set the threshold of the electric quantity required for the camera 1 to operate in different camera shooting modes.
In step 220, displaying a first icon for setting a first threshold S1 and a second icon for setting a second threshold S2 on the intelligent video recording setting interface 20, where the first icon S1 and the second icon S2 are used for sliding in a preset area by the user's fingers, and different positions of the first icon S1 and the second icon S2 in the preset area correspond to different electric quantity values.
In step 230, displaying a first text corresponding to the first icon S1 and a second text corresponding to the second icon S2 on the intelligent video recording setting interface 20. The contents displayed by the first text and the second text are respectively electric quantity values corresponding to positions where the first icon S1 and the second icon S2 are located.
As shown in
In step 240, acquiring a first electric quantity value corresponding to the position where the first icon is located in the preset area.
Different positions of the first icon S1 in the preset area correspond to different electric quantity values. The position where the first icon S1 is located may be preset or may be set by the user himself. The first threshold S1 can be set by acquiring the first electric quantity value corresponding to a position where the first icon S1 is located in the preset area at the current time. In some embodiments, the minimum value of the first electric quantity value is 10% of the maximum charge capacity of the battery in order to better prolong battery usage life of the camera 1.
In step 250, storing the first electric quantity value as the first threshold S1 in the memory 12 of the camera 1.
The first electric quantity value is stored in the memory 12 of the camera 1 as the first threshold S1, so that the processor of the camera 1 can directly read the first threshold S1 from the memory of the camera 1 when executing the method for controlling battery life of a camera provided in
In step 260, acquiring a second electric quantity value corresponding to the position where the second icon is located in the preset area.
In step 270, storing the second electric quantity value as the second threshold S2 in the memory 12 of the camera 1.
The steps 260 to 270 are similar to the steps 240 to 250, and therefore, the principle and implementation of the steps 260 to 270 can be referred to the steps 240 to 250, which will not be described in detail herein.
In the embodiment of the present application, a user can slide the first icon S1 and the second icon S2 in the preset area in the intelligent video recording setting interface 20 displayed on the screen of the electronic device 2 so as to set the first threshold S1 and the second threshold S2, so that different requirements of the user can be satisfied. Furthermore, a first text and a second text are displayed on the intelligent video recording setting interface 20, the contents displayed by the first text and the second text are respectively electric quantity values corresponding to the positions where the first icon S1 and the second icon S2 are located, and the first text and the second text can move along with the sliding of the first icon S1 and the second icon S2 respectively, so that a user can directly and quickly learn the electric quantity values corresponding to the positions where the first icon S1 and the second icon S2 are located from the contents displayed by the first text and the second text, thereby improving the user experience.
To further enhance the user experience, in some embodiments, the first icon S1 is displayed in a first color, e.g., red. The second icon S2 is displayed in a second color, e.g., blue. The user experience is further improved by arranging that the first icon S1 and the second icon S2 are displayed in different colors so that the user can quickly distinguish between the first icon S1 and the second icon S2.
In step 301, acquiring a current electric quantity value S of a camera 1.
The present step is the same as step 110, and therefore, the principle and specific implementation of the present step can be referred to step 110, which will not be described in detail.
In step 302, determining whether the current electric quantity value S is greater than or equal to the second threshold S2, i.e., S≥S2. If so, proceed to step 303; if not, proceed to step 305.
In step 303, controlling the camera 1 work in a high-electric quantity mode, and a power at which the camera 1 operates in the high-electric quantity mode to be a first power P1.
In step 304, adjusting a luminous power of a fill light to a first luminous power W1, and control an image capture unit 15 to record at a first video recording frame rate F1, wherein 0<F1≤Fmax, 0<W1≤Wmax.
Within a certain range, the greater the video recording frame rate of the video recorded by the image capture unit 15, the better the fluency of the video obtained from the video recording. The greater the luminous power of the fill light 16, the greater the illumination intensity. In steps 303 and 304, since the current electric quantity value S is greater than or equal to the second threshold S2, it is indicated that the electric quantity remaining in the camera 1 at the current time is sufficient, and by controlling the camera 1 works in a high-electric quantity mode so as to control the luminous power of the fill light 16 to be adjusted to a larger first power W1, the image capture unit 15 performs video recording at a larger first video recording frame rate F1, thereby ensuring the clarity and fluency of the video obtained from the video recording.
It is worth mentioning that the turning on and off of the fill light 16 is determined by the illumination intensity of the monitored area, independently of the current electric quantity value S. If the illumination intensity of the monitored area is weak and cannot meet the requirements of the video recording, the fill light 16 is controlled to turn on to enhance the illumination intensity of the monitored area. If the illumination intensity of the monitored area can meet the video recording requirements, it is not necessary to turn on the fill light 16. When the fill light is turned on, the luminous power thereof is adjusted according to the current electric quantity value S.
Therefore, in step 304, the luminous power of the fill light 16 is adjusted to be a first power W1, and the image capture unit 15 is controlled to perform video recording at a first video recording frame rate F1, which specifically means that the image capture unit 15 is controlled to perform video recording on the monitored area at the first video recording frame rate F1; and if the illumination intensity of the monitored area is weak, the fill light 16 needs to be turned on so as to enhance the illumination intensity of the monitored area, the fill light 16 operates with the luminous power as the first luminous power W1. If the illumination intensity of the monitored area meets the video recording requirements, it is not necessary to turn on the fill light 16. It should be noted that the above explanation applies to the steps similar to step 304 throughout, and the explanation will not be repeated later.
In this step, the first luminous power W1 and the first video recording frame rate F1 may be set as required, and may generally be set to a larger value. For example, the first luminous power W1 may be set to Wmax, 0.9×Wmax, or 0.8×Wmax, and the first video recording frame rate F1 may be set to Fmax, 0.9×Fmax, or 0.8×Fmax. When F1=Fmax and W1=Wmax, the fill light 16 is operated at its maximum luminous power Wmax, and the image capture unit 15 is operated at its maximum video recording frame rate, so as to sufficiently ensure that the clarity and fluency of the video obtained from video recording reach an optimal state.
In step 305, determining whether the current electric quantity value S is greater than or equal to the first threshold S1. If so, proceed to step 306; if not, proceed to step 308.
In step 306, controlling the camera 1 to work in a medium-electric quantity mode, and a power at which the camera 1 operates in the medium-electric quantity mode to be a second power P2.
In step 307, adjusting the luminous power of the fill light 16 to a second luminous power W2, and controlling an image capture unit 15 to perform video recording at a second video recording frame rate F2, where 0<F2<F1 and 0<W2<W1.
If the electric quantity value S is greater than or equal to the first threshold S1 but is less than the second threshold S2, i.e., S1≤S<S2, it is indicated that the electric quantity remaining in the camera 1 at the current time is at an intermediate level, and compared with the case where the electric quantity remaining in the camera 1 is large, in steps 306-307, the camera 1 is controlled to work in a medium-electric quantity mode, the luminous power of the fill light is adjusted to a second luminous power W2 which is smaller than the first luminous power W1, and the image capture unit is controlled to perform video recording at a second video recording frame rate F2 which is smaller than the first video recording frame rate F1, thereby effectively reducing the power of the camera 1, and thus reducing the power consumption of the camera 1; as a result, the battery usage life time of the camera 1 is prolonged.
The second luminous power W2 and the second video recording frame rate F2 may be set as required, for example, the second luminous power W2 may be set to 0.6×Wmax, 0.5×Wmax or 0.4×Wmax, and the second video recording frame rate F2 may be set to 0.6×Fmax, 0.5×Fmax or 0.433 Fmax.
In step 308, controlling the camera 1 to work in a low-electric quantity mode, and a power at which the camera 1 operates in the low-electric quantity mode to be a third power P3, where P1>P2>P3.
In step 309, controlling the camera 1 to enter the standby state when the camera 1 works in the low-electric quantity mode, where when the camera 1 is in the standby state, the sensing unit 17 is in the operating state.
If the electric quantity value S is less than the first threshold S1, i.e., S<S1, it is indicated that the electric quantity remaining in the camera 1 at the current time is small. Therefore, when the camera 1 is controlled to enter the standby state in steps 308 to 309, the image capture unit 15 and the fill light 16 also enter the standby state, so that the power consumption of the camera 1 is reduced, and the battery life time of the camera 1 is prolonged.
In the standby state, all the other units except the sensing unit 17 can be turned off to save power consumption. Since the power consumption of the sensing unit 17 is generally low, the sensing unit 17 will not consume too much power for continued operation. Therefore, in step 309, when controlling the camera 1 to enter the standby state, the sensing unit 17 is in the operating state, and the safety monitoring of the monitored area is continuously maintained, so as to ensure the safety monitoring effect without consuming much power.
In step 310, when the camera 1 is in the standby state, in response to the sensing unit 17 of the cameral detecting the presence of an intruding target, adjusting the luminous power of the fill light to a third luminous power W3, and controlling the image capture unit to perform video recording at the third video recording frame rate F3, where 0<F3≤Fmax, and 0<W3≤Wmax.
When the camera 1 is in the standby state, if the sensing unit 17 detecting the presence of the intruding target in the monitored area, the camera 1 is woken up, and the camera 1 is controlled to perform a video recording to monitor the intruding target. The third luminous power W3 and the third video recording frame rate F3 can be set as required, for example, the third luminous power W3 can be set to Wmax, 0.9*Wmax or 0.8*Wmax, and the third video recording frame rate F3 can be set to Fmax, 0.9*Fmax or 0.8*Fmax. When F3=Fmax and W3=Wmax, the fill light is operated at its maximum luminous power, and the image capture unit 15 is operated at its maximum video recording frame rate, which can sufficiently ensure the clarity and fluency of the video obtained from video recording upon presence of an intruding target.
In step 311, when the camera 1 is in the standby state, in response to the operation of previewing the recorded video, adjusting the luminous power of the fill light 16 to the third luminous power W3, and controlling the image capture unit 15 to perform video recording at the third video recording frame rate F3.
In order to improve the user experience, the user can view the video recorded by the camera 1 via the electronic device 2 communicatively connected to the camera 1, so as to facilitate the user to know what happens in the monitored area in real time, for example, whether there is an intruding target in the monitored area, for example, the user can view the video recorded by the camera 1 in real time via a mobile phone. In this step, the operation of previewing the recorded video can be an operation performed by a user on the electronic device 2 communicatively connected to the camera 1, and the video obtained from real-time video recording by the camera 1 is viewed through the operation. Therefore, when the camera 1 is in a standby state, if the user selects to preview a recorded video, the camera 1 is woken up, and the camera 1 is controlled to perform a video recording, so that the user can know the security of the current monitored area through the video recorded by the camera 1.
In step 312, in response to the sensing unit detecting that the intruding target leaves the monitoring area, or ending the operation of previewing the recorded video, controlling the operating state of the camera to switch back to the standby state.
If the sensing unit 17 detects the intruding target leaving the monitored area, it is indicated that the monitored area is in a safe state, the image capture unit 15 and the fill light 16 may be turned off. When the user selects to end previewing the recorded video, the image capture unit 15 and the fill light 16 may be turned off. In this step, when it is detected that the intruding target leaves the monitored area or the user selects to end previewing the recorded video, the operating state of the camera 1 is timely controlled to switch back to the standby state, so that the power consumption of the camera 1 is reduced and the battery usage life time of the camera 1 is prolonged.
It is worth noting that in different camera shooting modes, the luminous power of the fill light 16 in the camera 1 and the video recording frame rate of the image capture unit 15 are different. When the camera 1 works in a low-electric quantity mode, the camera 1 enters the standby state, and at this time, the camera 1 does not perform video recording any more, i.e., the video recording frame rate is 0. When the sensing unit 17 detects presence of an intruding target in the monitored area or the user selects the operation of previewing the recorded video, in steps 310-311, the luminous power of the fill light 16 is adjusted to the third power W3, and the image capture unit 15 is controlled to perform video recording at the third video recording frame rate F3, it is indicated that the mode of the camera 1 is switched from the low-electric quantity mode to the luminous power of the fill light 16 to the third power W3, and the image capture unit 15 performs a mode of performing video recording at the third video recording frame rate F3. Therefore, in order to prolong the battery life time of the camera 1, when the sensing unit 17 detects the intruding target leaving the monitored area, or the user selects to end the operation of previewing the recorded video, the camera 1 is controlled to switch back to the low-electric quantity mode from the current camera shooting mode (the luminous power of the fill light 16 is the third luminous power W3, and the image capture unit 15 performs video recording at the third video recording frame rate F3), that is, the camera 1 enters the standby state. The above explanation is applied to the steps similar to the steps 310 to 312 in the following, and the explanation will not be repeated later.
It should be noted that in the embodiment shown in
In the embodiment of the present application, if the remaining electric quantity of the camera 1 at the current time is relatively large, the luminous power of the fill light 16 is adjusted to a relatively large power, and the camera 1 is controlled to perform video recording at a relatively large video recording frame rate, so as to ensure that the video obtained from the video recording has better clarity and better fluency. If the remaining electric quantity of the camera 1 is at an intermediate level at the current time, the luminous power of the fill light is adjusted to a lower power, and the camera 1 is controlled to perform video recording at a lower video recording frame rate, thereby extending the battery life time of the camera 1 and satisfying the requirement of stable video recording for a long time. If the remaining electric quantity of the camera 1 at the current time is less, then in the case where there is no intruding target in the monitored area and the user does not select to preview the recorded video, the operating state of the camera 1 is controlled to enter a standby state, so as to reduce the power consumption of the camera 1, so that upon presence of an intruding target in the monitored area or the user selects to preview the recorded video in a longer period, the camera 1 can still perform video recording in time, so as to realize the function of the camera 1 monitoring the monitored area.
Based on the foregoing embodiment, in the embodiment of the present application, the method for prolonging battery usage life of a camera further includes the steps of:
In step a01, when the camera 1 works in the medium-electric quantity mode, in response to the sensing unit 17 detecting presence of an intruding target in a monitored area, adjusting the luminous power of the fill light to a third luminous power W3, and controlling the image capture unit 15 to perform video recording at a third video recording frame rate F3, wherein 0<F2<F3≤Fmax, and 0<W2<W3≤Wmax.
In step a02, when the camera 1 works in the medium-electric quantity mode, in response to the operation of previewing the recorded video, adjusting the luminous power of the fill light 16 to a third luminous power W3, and control the image capture unit to perform the video recording at the third video recording frame rate F3.
In step a03, in response to the sensing unit 17 detecting the intruding target leaving the monitored area, or ending the operation of previewing the recorded video, controlling the mode of the camera to switch back to the medium-electric quantity mode.
The steps a01-a03 are similar to steps 310-312, and therefore, the principle and implementation of steps a01-a03 can be referred to the steps 310-312, which will not be described in detail herein.
In the embodiment of the present application, when the camera 1 works in a medium-electric quantity mode, that is to say, when the remaining electric quantity of the camera 1 is at an intermediate level, if the sensing unit 17 detects presence of an intruding target in the monitored area, the luminous power of the fill light 16 is adjusted from the lower second luminous power W2 to the higher third luminous power W3 in time, and the video recording frame rate of the image capture unit 15 is adjusted from the lower second video recording frame rate F2 to the higher third video recording frame rate F3, so that better monitoring can be performed on the intruding target, and the case where the entire behavior of the intruding target within the monitored area cannot be completely recorded due to the small video recording frame rate of the image capture unit 15, and the case where the intruding target cannot be effectively discriminated from the video obtained from the video recording due to the weak illumination intensity of the monitored area are avoided. When the user selects to preview the recorded video, the illuminous power of the fill light 16 and the video recording frame rate of the image capture unit 15 are increased in time to improve the clarity and fluency of the video obtained from the video recording. After detecting the intruding target leaving the monitored area or the user finishes previewing the recorded video, the sensing unit 17 switches the mode of the camera 1 from the higher-power mode back to the lower-power medium-electric quantity mode in time, thereby extending battery usage life time of the camera.
In some embodiments, the first video recording frame rate F1 is set to Fmax and the first power W1 is set to Wmax in order to further improve the clarity and fluency of the video obtained from video recording. In the embodiment of the present application, if the remaining electric quantity of the camera 1 is relatively large, by setting the video recording frame rate of the image capture unit as the maximum video recording frame rate, the fluency of the video recorded by the image capture unit reaches an optimal state. By setting the luminous power of the fill light as the maximum luminous power, when the fill light is in an on state, the illumination intensity of the monitored area can reach an optimal state, and the clarity of the video recorded by the image capture unit is improved.
In some embodiments, step 310 and/or step a01 include:
Step b01, in response to the sensing unit 17 detecting the presence of the intruding target in the monitored area, controlling the AI detection unit 18 to acquire a current image acquired at a current time of the image capture unit 15, and perform intruding target identification on the current image.
For other sensing units, such as PIR units, a misjudgment may occur when identifying whether there is an intruding target in the monitored area, especially in scenarios such as leaf shaking, having a hotter airflow, or even light changes, etc. Therefore, the camera 1 is provided with the AI detection unit 18, and humanoid identification, vehicle type identification, etc. are performed on the current image by the AI detection unit 18, thereby improving the accuracy of determining whether there is the intruding target in the monitored area.
If the camera 1 is in a standby state, after the sensing unit 17 detects the presence of the intruding target in the monitored area, the image capture unit 15 is woken up to capture the monitored area so as to obtain a current image, and the AI detection unit 18 is controlled to perform intruding target identification on the current image. If the mode of the camera 1 is the medium-electric quantity mode, the control AI detection unit 18 directly acquires the current image captured by the image capture unit 15 at the current time, and performs intruding target identification on the current image.
Step b02, if the AI detection unit 18 identifies the intruding target from the current image, adjusting the luminous power of the fill light to the third luminous power W3, and controlling the image capture unit 15 to perform video recording at the third video recording frame rate F3.
The present step is similar to step 310, and therefore, the principle and specific implementation of the present step can be referred to step 310, which will not be described in detail.
In the embodiment of the present application, by providing the AI detection unit 18 in the camera 1, only when both the sensing unit 17 and the AI detection unit 18 detect the intruding target, the presence of the intruding target in the monitored area is confirmed, and compared with the method of only detecting whether the intruding target is present in the monitored area by means of the sensing unit 17, the misjudgment can be reduced and the accuracy of the judgement can be improved.
In some embodiments, the third video recording frame rate F3 is set to Fmax and the third luminous power W3 is set to the maximum luminous power Wmax in order to completely record all of the behavior of the intruding target in the monitored area and to improve the user experience while previewing the recorded video.
In some embodiments, based on the embodiment provided in
Step c01, if the electric quantity value S is greater than or equal to the second threshold S2, i.e., S≥S2, controlling the AI detection unit 18 to parse the video recorded by the camera 1.
If S≥S2, it is indicated that there is a large electric quantity remaining in the camera, the AI detection unit 18 may be started to parse the video. The AI detection unit 18 parses the video recorded by the camera 1, including adding labels or tags to specific objects in the video picture, such as people, cars, animals, etc. using the AI detection unit 18, and framing the objects using a detection frame, so that a user can quickly locate the objects when browsing the video.
Step c02: if the electric quantity value S is less than the second threshold S2, i.e., S<S2, turn off the AI detection unit 18.
If S<S2, it is indicated that the electric quantity remaining in the camera 1 is not large, and by turning off the AI detection unit 18, it is possible to reduce the power consumption of the camera 1 and thus to prolong the battery life time. In addition, the most important function of the camera 1 is to perform video recording monitoring on the monitored area, and the AI detection unit 18 is used to parse the video recording, only for the convenience of the user to quickly locate the target; therefore, in the case where the remaining electric quantity of the camera 1 is small, by turning off the AI detection unit 18, the camera 1 can continue to perform its monitoring duties within a long time, so as to ensure the safety of the monitored area.
In order to further increase the battery life time of the camera,
In step 401, determining whether a current time is within a preset timed video recording period. If so, proceed to step 402; if not, proceed to step 411.
The preset timed video recording period refers to a recording period preset by the user, that is, during this period, the user needs the camera 1 to perform video recording.
In step 402, determining whether the camera 1 is configured in a power-saving mode. If not, proceed to step 403; if so, proceed to step 404.
When the camera 1 is operated in the power-saving mode, the steps described in the foregoing embodiment, for example, steps 404 to 415 described below, are executed to prolong the battery usage life time of the camera 1.
In step 403, adjusting the luminous power of the fill light 16 to the maximum luminous power Wmax, and controlling the image capture unit 15 to record at the maximum video recording frame rate Fmax.
If the camera 1 is not configured in the power-saving mode, the operating states of the fill light 16 and the image capture unit 15 are adjusted to the maximum power state.
In step 404, acquiring a current electric quantity value S of the camera 1.
In step 405, determining whether the electric quantity value S is greater than or equal to the second threshold S2, i.e., S>S2. If so, proceed to step 406; if not, proceed to step 408.
In step 406, controlling the camera 1 to work in a high-electric quantity mode, and a power at which the camera 1 operates in the high-electric quantity mode to be the first power P1.
In step 407, adjusting the luminous power of the fill light 16 to the first luminous power W1, and controlling the image capture unit 15 to perform video recording at a first video recording frame rate F1, where 0<F1≤Fmax, and 0<W1≤Wmax.
In step 408, determining whether the electric quantity value S is greater than or equal to the first threshold S1, i.e., S≥S1. If so, proceed to step 409; if not, proceed to step 411.
In step 409, controlling the camera 1 to work in a medium-electric quantity mode, and a power at which the camera operates in the medium-electric quantity mode to be the second power P2.
In step 410, adjusting the luminous power of the fill light 16 to a second luminous power W2, and control an image capture unit 15 to perform video recording at a second video recording frame rate F2, where 0<F2<F1 and 0<W2<W1.
In step 411, controlling the camera 1 to work in a low-electric quantity mode, and a power at which the camera operates in the low-electric quantity mode to be the third power P3, where P1>P2>P3.
In step 412, when the camera 1 works in the low-electric quantity mode, controlling the camera 1 to enter the standby state, where when the camera 1 is in the standby state, the sensing unit 17 is in the operating state.
In step 413, when the camera 1 is in the standby state, in response to the sensing unit 17 detecting the presence of an intruding target, adjusting the luminous power of the fill light to a third luminous power W3, and controlling the image capture unit 15 to perform video recording at the third video recording frame rate F3, where 0<F3≤Fmax, and 0<W3≤Wmax.
In step 414, when the camera 1 is in the standby state, in response to the operation of previewing the recorded video, adjusting the luminous power of the fill light 16 to the third luminous power W3, and controlling the image capture unit 15 to perform video recording at the third video recording frame rate F3.
In step 415, in response to the sensing unit 107 detecting that the intruding target leaves the monitoring area or ending the operation of previewing the recorded video, controlling the operating state of the camera 1 to switch back to the standby state.
The steps 404 to 415 are the same as the steps 301 to 312, and therefore, the principle and implementation of the steps 404 to 415 can be referred to the steps 301 to 312, which will not be described in detail herein.
In the embodiment of the present application, by determining whether the current time is within the preset timed video recording period, and if the current time is not within the preset timed video recording period, it is indicated that the user does not need to perform video recording by the camera 1; therefore, by controlling the camera 1 to enter the standby state, it is possible to reduce the power consumption of the camera 1 and prolong the battery usage life time. If the current time is within a preset timed video recording period, it is further determined whether the camera 1 is configured in a power-saving mode. If the camera is configured in the power-saving mode, the camera 1 is controlled to operate in the power-saving mode; and if the camera is not configured in the power-saving mode, the camera 1 is controlled to operate in a high-power mode. In this way, the user's different needs can be met, and the user experience can be improved.
