[0002] In vehicle-mounted embedded applications, the camera device in the electromagnetic compatibility test environment is easily affected by the factors of the camera device itself, which will generate noise and affect the image acquisition of the camera device. At the same time, the camera device in the electromagnetic compatibility test environment is always Under strong electromagnetic interference, the camera device is prone to failure, resulting in the camera device not working properly. Therefore, it is necessary to automatically detect the camera device in the electromagnetic compatibility test environment to ensure that the camera device can work normally
[0003] In the prior art, in order to reduce the cost and the size of the controller, the controller directly outputs the image data after acquiring the image data from the camera device without processing and analyzing the original image to be collected. At this time, the image data is relatively large and requires a large bandwidth Only a high-quality wiring harness can meet the transmission of image data, which has high requirements for the isolation and transmission of electromagnetic compatibility testing, which increases the cost of testing
At the same time, the detection of the camera device in the electromagnetic compatibility test environment has not been automatically detected, resulting in a waste of personnel resources

The invention discloses a detection method and device of a vehicle-mounted camera device, a storage medium and a vehicle. The detection method comprises the steps of obtaining a to-be-detected image collected by a to-be-detected camera device; performing color mode conversion on the to-be-detected image to obtain a to-be-detected image in a target color mode; carrying out binarization processing on the to-be-detected image in the target color mode to obtain a binary image of the to-be-detected image, and according to the gray value of each pixel point in the binary image, carrying out accumulation processing on the pixel points of which the gray value is a preset value to obtain a first area value of the to-be-detected image; determining a plurality of continuous target pixel points of which the gray values are preset values from each row or each column in the binary image; performing accumulation processing on the plurality of continuous pixel points corresponding to each row or each column to obtain a second area value of the to-be-detected image; and performing image detection on the to-be-tested camera device according to the first area value and the second area value, thereby realizing automatic detection of the vehicle-mounted camera device in the electromagnetic compatibility test, and reducing the bandwidth of data transmission.
Description
technical field [0001] The present application relates to the technical field of automatic detection of camera devices in an electromagnetic compatibility test environment, and in particular to a detection method, device, storage medium and vehicle of a vehicle-mounted camera device. Background technique [0002] In vehicle-mounted embedded applications, the camera device in the electromagnetic compatibility test environment is easily affected by the factors of the camera device itself, which will generate noise and affect the image acquisition of the camera device. At the same time, the camera device in the electromagnetic compatibility test environment is always Under strong electromagnetic interference, the camera device is prone to failure, resulting in the camera device not working normally. Therefore, it is necessary to automatically detect the camera device in the electromagnetic compatibility test environment all the time to ensure that the camera device can work norm...
