The embodiment provided by the application is an embodiment of a control method of an electronic exterior rearview mirror of an automobile.
Embodiments of the present application are described in detail below with reference to fig. 1 and 2.
The control method of the automobile electronic exterior rearview mirror is characterized in that the automobile electronic exterior rearview mirror is provided with a visible light camera and an infrared camera, and comprises the following steps:
step S100, when the vehicle stops using, and the external locking of the vehicle is detected, the external rearview mirror is retracted to a position flush with the external surface structure of the vehicle, so that the external rearview mirror is prevented from being scratched possibly in the parking process. In the present embodiment, when it is determined that the outside is locked, the opening operation of the outside rear view mirror is performed.
Step S200, collecting vehicle environment information;
when the vehicle environment information is collected in the embodiment, the conditions of sunlight, rainwater, humidity, smoke and the like of the external environment are collected by using a sunlight and rainfall sensor, a smoke sensor and a humidity sensor.
Step S300, judging whether the vehicle environment information data exceeds a threshold value;
step S400, when the threshold value is not exceeded, judging that the current day is in good weather, and displaying the current day on a display screen by using only a visible light camera;
and S500, when the threshold value is exceeded, judging that the night and/or the weather is bad, simultaneously using the visible light camera and the infrared camera at the moment, and displaying the fused automobile external scene acquired by the visible light camera and the infrared camera on a display screen.
In this embodiment, a plurality of levels of threshold values T may be set, and only in the daytime and in the good weather, the use of the infrared camera is unnecessary, so that the threshold value is used, the infrared camera is generally required at night, and the infrared camera is also generally required at severe weather, so that the two threshold values at night and in severe weather can be used, and the situation that fusion is required can be determined. If the judgment threshold value of day and night is A and the weather condition is B, the condition of using only the visible light camera is T1 (<=A and < =B), the condition of needing the fusion of the two cameras is T2 (> A) or T3 (> B), and then different displays are carried out according to the judgment result.
The outside scene fusion front that gathers visible light camera and infrared camera includes: denoising, enhancing and image registering the acquired image information to find out corresponding pixel points in the two images acquired by the two cameras. The method is used for eliminating interference, so that the image information acquired by the two cameras can be fused together better.
When the visible light camera and the infrared camera are used for acquiring the automobile external field Jing Rong, a pyramid structure decomposition and non-downsampling contourlet transformation method is adopted, and the method comprises the following steps:
step S511, high-frequency and low-frequency information extraction is carried out on the acquired image information by using three-layer pyramid structure decomposition;
step S512, fusing the extracted corresponding high-frequency and low-frequency information by adopting a non-downsampling contourlet transformation method;
step S513, carrying out inverse transformation on the fused high-frequency information and the fused low-frequency information to obtain final fusion information.
Referring to fig. 2, in actual use, it is first determined whether the outside of the vehicle is locked, and when the determination is yes, the vehicle is in a non-use state at this time, and the outside rear view mirror is controlled to retract. When judging to be no, the vehicle is in a use state at this moment, the central processing unit processes information acquired by the smoke, humidity and sunlight rainfall sensors, then judges whether the processing result is larger than a corresponding threshold value T, when judging to be no, the vehicle is in a daytime and good weather condition at this moment, only the visible light camera can be opened to be used as a rearview mirror, and pictures are displayed on a plurality of display screens in the vehicle. When the image is judged to be larger than the threshold T, the infrared camera and the visible light camera can be turned on at the same time, then the images acquired by the infrared camera and the visible light camera are fused, and the images are displayed on a plurality of display screens in the vehicle after the processing is completed. The judgment is periodic, for example, the vehicle is used in the daytime under the condition of good weather, but the weather is bad for a period of time, and the bad weather can be judged again at the moment, so that the infrared camera can be applied in time, and the whole process is more flexible.
In summary, the visible light camera and the infrared camera are used on the external rearview mirror at the same time, and based on different imaging mechanisms, natural complementarity exists between the visible light image and the infrared image. The visible light camera can well capture color and detail information, but the visible light camera does not perform well at night or other scenes with lower visibility; the infrared camera has low capability of capturing details, but can capture contour information in the environment with low visibility at night. And the two are fused to play a role in complementarity. The method is particularly suitable for environments with low visibility such as rainy and snowy seasons, night, foggy days and the like, and a driver can clearly observe information behind the vehicle, so that driving experience and safety are improved. In addition, the problem that the width of the vehicle is increased when the external rearview mirror protrudes out of the surface of the vehicle is solved, when the external locking of the vehicle is detected, the electronic external rearview mirrors on two sides are controlled to be retracted to the vehicle body and are flush with the structure of the external surface of the vehicle, so that the width of the vehicle is reduced, and the risk that the vehicle is scratched by mistake in a non-vehicle scene is avoided. The control method of the electronic exterior rearview mirror comprises an information acquisition module, a data processing module, a control module and a display module, so that the definition of the picture presentation of the electronic exterior rearview mirror can be effectively ensured to a certain extent, and the safety of drivers, passengers and vehicles is improved.

As shown in fig. 3 and 4, the present application provides a control system for an electronic exterior mirror of an automobile, comprising:
the information acquisition module is used for acquiring images of the rear side view of the automobile and vehicle environment information, and comprises a visible light camera and an infrared camera, wherein the visible light camera and the infrared camera are used for shooting images of the rear side view of the automobile and mainly play a role in visual complementation; the information acquisition module further comprises:
the sunlight and rainfall sensor detects the light condition of the current scene, detects the current scene such as day, night or passing through a tunnel, and judges whether the current weather is rainy or not by detecting whether water exists on the front windshield;

the humidity sensor is used for detecting the humidity of the environment outside the vehicle, is usually combined with the solar energy rain sensor and the smoke sensor, and is used for judging the environment outside the vehicle and improving the accuracy;
the data processing module judges the condition of the outside environment of the vehicle through the detection results of the sunlight and rainfall sensor, the smoke sensor and the humidity sensor. The data processing module, namely the central processing unit, is generally integrated in the automobile electronic exterior rearview mirror control unit, gathers the vehicle environment information acquired by the information acquisition module, and sends the decision result to the control module. Meanwhile, an image processing algorithm is integrated in the data processing module, and preprocessing and fusion operation can be carried out on information acquired by the visible light camera and the infrared camera.
When the information collected by the visible light camera and the infrared camera is preprocessed, the collected image information is subjected to denoising, enhancement and image registration, and corresponding pixel points in two images collected by the two cameras are found. When the information acquired by the visible light camera and the infrared camera is fused, a pyramid structure decomposition and non-downsampling contourlet transformation method is adopted, and the method comprises the following steps: extracting high-frequency and low-frequency information from the acquired image information by using three-layer pyramid structure decomposition; fusing the extracted corresponding high-frequency and low-frequency information by adopting a non-downsampling contourlet transformation method; and carrying out inverse transformation on the fused high-frequency information and the fused low-frequency information to obtain final fusion information. The fusion scene obtained in this way not only realizes the complementation of the infrared camera and the visible camera, but also highlights the detail components, so that the scene observed by the driver is clearer.

When the vehicle is used, the central processing unit judges the external environment where the current vehicle is located according to the environment information acquired by various sensors, the thresholds are T1, T2 and T3, and the threshold size is configurable. If the current daytime and good weather are judged, the electronic outside rearview mirror control unit only enables the visible light camera according to the decision result of the central processing unit, and fusion processing of the outside scene acquired by the visible light camera and the infrared camera is not needed at the moment; if the electronic outside rearview mirror control unit judges that the electronic outside rearview mirror is currently in complex scenes such as night, rainy and snowy weather and haze, the electronic outside rearview mirror control unit enables the visible light camera and the infrared camera simultaneously, the central processing unit can fuse scene information acquired by the visible light camera and the infrared camera, and finally the fused clear scene is displayed on an in-vehicle display screen, so that the safety of the vehicle driving process is guaranteed. When the vehicle stops being used, when the outside locking of the vehicle is detected to be executed, the electronic outside rearview mirror control unit executes the retracting operation of the outside rearview mirror, and the outside rearview mirror is retracted to the position flush with the structure of the outer surface of the vehicle, so that the possible false scratch and scratch in the vehicle parking process is prevented.
