specific Embodiment approach

[0024] A method for detecting an abnormality in which a captured image is bluish in the present invention judges the abnormality by analyzing the pixel feature of the B channel in the RGB format color image generated by the capturing device. The B channel is the blue channel, which specifically includes the following step:

[0025] Step 1: Divide the pixel value interval [0,255] into four small areas on average: A1=[0,64], A2=[64,128], A3=[128,192], A4=[192,255], the embodiment of the present invention chooses one A color image in RGB format generated by a capture device;

[0026] Step 2: Count the sum of the number of pixels in the image whose blue channel values ​​are in the four small areas of A1-A4, and calculate the ratio of the sum to the total number of pixels in the entire image, and the results are respectively recorded as: R1, R2, R3, R4, wherein R1=5%, R2=38%, R3=48%, R4=9%;

[0027] Step 3: According to the results obtained in step 2), it shows that R2>>R1 and R2...

Abstract

The invention relates to an abnormality detection method for a bluish captured image. The abnormality detection method can detect the abnormality of the occurrence of a bluish image by analyzing pixel point features of a B channel in the color image in the format of RGB generated by a capture device. Through the above technology, the invention can carry out a timely failure diagnosis of the device of a capture system by analyzing the pixel point features of the B channel of the color image in the format of RGB generated by the device and by analyzing the captured image in a non-power-off state. The abnormality detection method is timely and highly efficient, saves human and material resources, takes less time and energy, and is highly efficient, intelligent, scientific, and suitable for promotion and application.

Description

technical field [0001] The invention relates to the technical field of image anomaly detection, in particular to an anomaly detection method for detecting whether a captured image is bluish by analyzing image color information. Background technique [0002] The equipment in the vehicle capture system is working outdoors, with the characteristics of uninterrupted operation, heavy workload, and harsh working environment. In addition to the situation of man-made damage to the equipment, the equipment is affected by many factors of itself and the outside world, which will lead to frequent failures. How to diagnose the faults of the equipment of the capture system in a timely, efficient and non-stop state is a problem that traffic information managers need to solve urgently. [0003] At this stage, the diagnosis of capture device failures still relies on the tedious and simple way of manpower. Generally, there are two ways: the first way is to check the image database collected...
