Problems solved by technology

However, after washing the camera, the remaining water stains on the camera will affect the imaging of the camera, and frost will also occur in cold weather, making the camera unable to use normally
At the same time, these cleaning equipment also greatly increase the volume of the camera, which is difficult to be practically applied.

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...

Abstract

The invention discloses a method and device for maintaining the image quality of a vehicle-mounted camera, and the vehicle-mounted camera. The method comprises the steps: carrying out the image quality evaluation of an image photographed by the vehicle-mounted camera at regular time; when the evaluated image quality does not meet the preset condition, detecting whether stains exist on a window ofthe vehicle-mounted camera or not; when it is detected that stains exist, obtaining the current motion state of the vehicle; when the previous motion state meets the safety condition, controlling a cleaning device to clean the window, wherein the cleaning device is arranged on the vehicle-mounted camera; and controlling a heating device on the vehicle-mounted camera to dry the cleaned window. According to the invention, image quality maintenance can be automatically carried out on the unmanned vehicle, and whether the motion state of the vehicle meets a safety condition is judged before the vehicle-mounted camera is cleaned; it is guaranteed that cleaning of the vehicle-mounted camera does not influence the driving safety of the vehicle, and the driving safety of the automatic driving vehicle is guaranteed.

Description

technical field [0001] The invention relates to the field of assisted driving, in particular to a method and device for maintaining the image quality of a vehicle-mounted camera and the vehicle-mounted camera. Background technique [0002] With the rapid development of the automobile industry, there are more and more sensors on the car body, and the automatic maintenance and maintenance of these sensors is becoming more and more important. Especially for visual sensors, the stains on the window or lens will seriously affect the imaging quality, leading to corresponding function failure, vehicle accidents, and potential safety hazards. [0003] There are some maintenance strategies for vehicle-mounted cameras in the prior art, such as installing the camera inside the vehicle body to avoid the influence of dust, mud and raindrops on the camera. And must be installed on the camera outside the vehicle body as reversing, the prior art is more by installing a set of cleaning equi...
