Patent Application
20150242693
The present disclosure relates to video surveillance devices, and particularly to a video surveillance device and a video surveillance method applied by the video surveillance device.
Surveillance systems sometimes includes more than one image source device such as a video recorder or an IP camera. Each image source device captures videos or images, and can transmit the captured videos or images over a network to at least one terminal device (for example, a mobile device or a computer), to show the videos or images on the terminal device.
Implementations of the present technology will now be described, by way of example only, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts have been exaggerated to better illustrate details and features of the present disclosure.
Several definitions that apply throughout this disclosure will now be presented.
The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like.
Referring to
In the example illustrated in
The request receiving module 101 receives a request from at least one terminal device 3, and determines whether the request includes information specifying at least two image source devices 2. The specific information of one image source device 2 can be an IP address of that image source device 2.
The obtaining module 102 obtains images captured by each of the at least two specific image source devices 2 in real-time.
The grouping module 103 groups the obtained images together. In at least one embodiment, the grouping module 103 groups the obtained images according to an image resolution classification of each obtained image.
The transmitting module 104 transmits the grouped image to the terminal device 3.
In at least one embodiment, the system 100 further includes a generating module 105. When the request receiving module 101 determines that the request includes information specifying at least two image source devices 2, the generating module 105 generates an original image 1050 (shown in
In at least one embodiment, the storage unit 10 further stores a relationship between the different image source devices 2 and the image resolution classifications. Each image source device 2 corresponds to one image resolution classification. The generating module 105 determines one image resolution classification corresponding to each specific image source device 2 according to the stored relationship, generates blank portions of sizes which are determined according to the image resolution classification of the corresponding specific image source device 2, and groups the generated blank portions together into the original image 1050. Referring to
In at least one embodiment, the terminal device 3 further periodically sends a new request to the video surveillance device 1, to request the video surveillance device 1 to periodically obtain the real-time captured images from each specific image source device 2. For example, the terminal device 3 can send a new request to the video surveillance device 1 every two seconds. The request receiving module 101 receives the new requests from the terminal device 3. The obtaining module 102 obtains the images captured by each specific image source devices 2 in real-time every time that the request receiving module 101 receives a new request from the terminal device 3. Then, the grouping module 103 repeats the grouping of the obtained images, and the transmitting module 104 repeats the transmitting of the grouped image to the terminal device 3. As such, the terminal device 3 successively displays a number of grouped images from the specific image source devices 2.
In block 41, a request receiving module receives a request from at least one terminal device.
In block 42, the request receiving module determines whether the request includes information specifying at least two image source devices; if yes, the process proceeds to block 43; otherwise block 41 is repeated.
In block 43, a generating module generates an original image including at least two blank portions each to correspond to one specific image source device.
In block 44, an obtaining module obtains images currently captured by each of the at least two specific image source devices in real-time.
In block 45, a grouping module adjusts an overall size and shape of the obtained images from each specific image source device to match an overall size and shape of the corresponding blank portion, and after the adjustment allocates the obtained images into the corresponding blank portion, thereby forming a grouped image.
In block 46, a transmitting module transmits the grouped image to the terminal device.
In block 47, the request receiving module determines whether a new request from the terminal device is received; if yes, block 44 is repeated; otherwise the process ends.
The embodiments shown and described above are only examples. Many details are often found in the art such as the other features of a video surveillance device. Therefore, many such details are neither shown nor described. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, especially in matters of shape, size and arrangement of the parts within the principles of the present disclosure up to, and including the full extent established by the broad general meaning of the terms used in the claims. It will therefore be appreciated that the embodiments described above may be modified within the scope of the claims.
