With the display assembly described hereinbefore, it is possible to improve the driving safety of the vehicle according to embodiments of the present disclosure at a low environmental visibility and also to improve the driving experience.
In the following, a display assembly, a displaying method thereof, and a vehicle having the same according to embodiments of the present disclosure will be described in detail with reference to drawings, which are explanatory, illustrative, and used to generally understand the present disclosure.
In some embodiments of the present disclosure, as shown in
Term “different environmental visibilities” used herein may include, for example, an environmental visibility on fine weather such as during the daytime and an environmental visibility on bad weather such as at night or on a foggy day. Term “landscape image” refers to an image which indicates actual road conditions (such as defects on a pavement, exits and entrances upon lane change, turns, and traffic situations) and actual scenes (such as buildings) on both sides of the road along a route.
With the image processing apparatus 2, the vehicle display screen 1 may display the actual landscape with a higher environmental visibility than the current environmental visibility, such that a driver can more clearly understand the actual road conditions and traffic situations along the same route at the current low environmental visibility, thereby ensuring the vehicle to run safely at the low environmental visibility, avoiding accidents caused by road traps and avoiding a lane changing opportunity to be missed due to the low environmental visibility, and improving the driving experience.
In these embodiments, the image processing apparatus 2 includes an image library 21, a camera 22, a comparator 23 and an image synthesizer 24. The image library 21 is configured to prestore a first landscape image of a first route captured at a first environmental visibility. The first landscape image may include actual road conditions (including defects on a pavement, exits and entrances upon lane change, turns, etc., except traffic situations) and actual scenes (such as buildings) on both sides of the road along the first route at the first environmental visibility. The camera 22 is configured to real timely shoot a second landscape image of the first route at a second environmental visibility, where the first environmental visibility is higher than the second environmental visibility. The second landscape image may include actual road conditions (including defects on a pavement, exits and entrances upon lane change, turns, and traffic situations) and actual scenes (such as buildings) on both sides of the road along the first route at the second environmental visibility. The comparator 23 is configured to compare the first landscape image and the second landscape image, so as to judge whether a real time position of the vehicle coincides with a position where the first landscape image is captured. The image synthesizer 24 is configured to synthesize the first landscape image and the second landscape image into an actual landscape image at the first environmental visibility and to send the actual landscape image to the vehicle display screen 1 when the comparator 23 determines that the real time position of the vehicle coincides with the position where the first landscape image is captured.
When the first environmental visibility is higher than the second environmental visibility, the first landscape image and the second landscape image can be synthesized by the image synthesizer 24 into the actual landscape image with a higher environmental visibility (i.e. the first environmental visibility). The actual landscape image may include actual road conditions (including defects on a pavement, exits and entrances upon lane change, turns, and traffic situations) and actual scenes (such as buildings) on both sides of the road along the first route. The vehicle display screen 1 can receive and real timely display the actual landscape image, such that a driver can more clearly understand the actual road conditions and traffic situations along the same route at the current low environmental visibility, thereby ensuring the vehicle to run safely at a low environmental visibility, and improving the driving experience.
In these embodiments, the image processing apparatus 2 further includes an adjusting circuitry 25. The adjusting circuitry 25 is configured to adjust the real time position of the vehicle to the position where the first landscape image is captured when the comparator 23 determines that the real time position of the vehicle does not coincide with the position where the first landscape image is captured. The adjusting circuitry 25 enables the real time position of the vehicle to coincide real timely with the position where the first landscape image is captured, such that the image synthesizer 24 can real timely synthesize the first landscape image with the second landscape image when the real time position of the vehicle coincides with the position where the first landscape image is captured, so as to obtain the actual landscape image at the first environmental visibility which is more real and accurate, thereby ensuring the vehicle to run more safely at a low environmental visibility and improving the driving experience.
Alternatively, in these embodiments, each of the first landscape image and the second landscape image is a landscape picture sequence or a landscape video sequence. The image synthesizer 24 can synthesize a first landscape picture with a second landscape picture at a same position; or the image synthesizer 24 can synthesize a first landscape video clip with a second landscape video clip at the same position, so as to form the actual landscape image at the same position at the first environmental visibility.
In these embodiments, the image synthesizer 24 is configured to supplement a brightness and colorfulness of the actual landscape image at the first environmental visibility, so as to allow the actual landscape image at the first environmental visibility to be more clear and discernible, thereby ensuring the vehicle to run more safely at a low environmental visibility and improving the driving experience.
In these embodiments, the vehicle display screen 1 is a front windshield of the vehicle.
It should be noted that, the vehicle display screen 1 may also be disposed on the front windshield of the vehicle. Alternatively, the vehicle display screen 1 may be disposed on a partial or entire surface of the front windshield of the vehicle. Alternatively, the vehicle display screen 1 may also be a vehicle projection screen, and the vehicle projection screen is disposed on the front windshield of the vehicle or is the front windshield of the vehicle. Each vehicle display screen 1 described above enables the driver to conveniently and real timely view the actual landscape image at the first environmental visibility from the front windshield of the vehicle when driving.
Furthermore, it should be noted that, the vehicle display screen 1 may also be vehicle glasses or disposed on the vehicle glasses. When driving at the second environmental visibility, the driver can real timely view the actual landscape image at the first environmental visibility from the vehicle glasses as long as wearing the vehicle glasses.
Based on the display assembly described above, in these embodiments, a displaying method of the display assembly is provided. The displaying method includes:
step S1: comparing, adjusting and synthesizing landscape images of a same route captured at different environmental visibilities; and
step S2: displaying, by a vehicle display screen, an actual landscape image with a higher environmental visibility than the current environmental visibility, based on a previously obtained result.
Specifically, as shown in
At step S10: a first landscape image of a first route captured at a first environmental visibility is prestored.
At step S11: a second landscape image of the first route at a second environmental visibility is real timely shot, where the first environmental visibility is higher than the second environmental visibility.
At step S12: the first landscape image and the second landscape image are compared, so as to judge whether a real time position of the vehicle coincides with a position where the first landscape image is captured.
At step S13: the first landscape image and the second landscape image are synthesized into the actual landscape image at the first environmental visibility and the actual landscape image is sent to the vehicle display screen, when the real time position of the vehicle coincides with the position where the first landscape image is captured.
At step S14: the real time position of the vehicle is adjusted to the position where the first landscape image is captured, when the real time position of the vehicle does not coincide with the position where the first landscape image is captured; and then step S13 is executed.
In addition, the step S13 further includes: supplementing a brightness and colorfulness of the actual landscape image at the first environmental visibility.
In other embodiments of the present disclosure, a display assembly is provided. The display assembly in these embodiments is substantially the same as that in the above embodiments shown in
Alternatively, the positioning circuitry 26 is disposed at a central position of the vehicle. The location of the positioning circuitry 26 enables a travel route of the vehicle to be more accurately positioned. In some embodiments, a GPS positioning system is used as the positioning circuitry 26, and positions the travel route of the vehicle in combination with a navigation map therein.
Further, it should be noted that, the position of the vehicle on a route can also be positioned by the positioning circuitry 26, such that the adjusting circuitry 25 can real timely adjust the position of the vehicle based on the positioning circuitry 26 when the comparator 23 determines that the real time position of the vehicle does not coincide with the position where the first landscape image is captured. The location of the positioning circuitry 26 in the vehicle also enables the vehicle to be real timely and accurately positioned.
Other structural circuitry of the display assembly in these embodiments are the same as that described with respect to the above embodiments shown in
The positioning circuitry 26 and the selecting circuitry 27 can actually position the vehicle when running on different routes and select the corresponding landscape image of each route captured at the first environmental visibility from the image library 21, so as to enable the image synthesizer 24 to subsequently synthesize the real timely captured landscape image of the same route with the landscape image captured at the first environmental visibility, such that a driver can more clearly understand the actual road conditions and traffic situations along the same route at the current low environmental visibility, thereby ensuring the vehicle to run safely at a low environmental visibility and improving the driving experience.
