Embodiment 1
[0054] Specifically, such as figure 2 As shown, the process of maintaining the image quality of the circuit module according to the method for maintaining the image quality of the vehicle-mounted camera disclosed in this application includes:
[0055] Step 1. The circuit module regularly acquires the images captured by the vehicle-mounted camera according to the preset time period and evaluates the image quality;
[0056] The on-board camera may also not have edge computing capabilities, and can directly transmit the image to the back-end processing unit of the vehicle through the communication interface, and the back-end processing unit will perform calculations such as image quality evaluation and stain detection, and then control according to the instructions of the back-end processing unit The cleaning device and heating device perform camera cleaning operations.
[0057] Step 2, when the evaluation image quality does not meet the preset conditions, image recognition is ...
Embodiment 2
[0073] Corresponding to the above-mentioned embodiments, this application provides a method for maintaining the image quality of a vehicle-mounted camera, such as Figure 4 As shown, the method includes:
[0074] 410. According to a preset time period, regularly evaluate the image quality of the images captured by the vehicle-mounted camera, where the vehicle-mounted camera is installed on the vehicle;
[0075] 420. When the evaluated image quality does not meet the preset condition, detect whether there is stain on the window of the vehicle camera through a preset method;
[0076] 430. Acquire the current motion state of the vehicle when stains are detected;
[0077] 440. When the current motion state satisfies a preset safety condition, control a cleaning device to clean the window;
[0078] The current motion state includes the driving speed of the vehicle, and when the current motion state satisfies a preset safety condition, controlling the cleaning device to clean the ...
Embodiment 3
[0095] Corresponding to the above-mentioned embodiments, the present application proposes a vehicle-mounted camera, the vehicle-mounted camera is arranged on the vehicle, the housing of the camera is provided with a window, a cleaning device for cleaning the window, and a heating and drying station. The heating device of the above-mentioned window,
[0096] The camera includes a calculation module, which is used to regularly evaluate the image quality of the images captured by the vehicle camera according to a preset time period; when the evaluated image quality does not meet the preset conditions, the vehicle camera is detected by a preset method Whether there are stains on the window of the vehicle; when the presence of stains is detected, the current motion state of the vehicle is obtained; when the current motion state meets the preset safety conditions, the cleaning device is controlled to clean the window; the on-board camera is controlled to The heating device dries the...
