Embodiment approach 1
[0124] figure 1 It is a schematic diagram of the processing flow of a light quality detection method according to an embodiment of the present invention; figure 1 As shown, the described method for detecting the quality of light includes the following processing steps:
[0125] S1. Continuously collect images of the area to be detected; the collection is real-time collection or extraction from video; preferably, real-time collection; preferably, the received or collected images are original images without digital processing;
[0126] S2. The images collected at every interval A (A is greater than or equal to 0) frames are extracted and processed in one frame; preferably, A=1;
[0127] S3. Divide the extracted image into M rows and N columns of sub-regions; each row has m pixels, each column has n pixels, m≥1, n≥1, m and n are preset; preferably, m=5 , n=5;
[0128] S4. set threshold value X, Y (X, Y correspond to upper limit, lower limit respectively, and upper limit thresh...
Embodiment approach 2
[0134] figure 2 Yes figure 1 Schematic diagram of the optional processing flow of the light quality detection method shown; figure 2 As shown, the method for detecting the quality of light also includes at least one of the following processing steps, preferably, all include:
[0135] S9. On the screen, display an insufficient brightness mark and an excessive brightness mark; the insufficient brightness mark or the excessive brightness mark is at least one of icons, covering colors, and light intensity values;
[0136] S10. On the screen, display a mark of insufficient brightness or a mark of excessive brightness on the detected sub-regions of insufficient brightness and excessive brightness;
[0137] S11. When insufficient or excessive brightness is detected, voice or sound prompts;
[0138] S12. On the screen, compare and display the image and the detection result; the two are respectively located on the left and right or up and down; preferably, the two are respectively...
Embodiment approach 3
[0147] image 3It is a schematic processing flow diagram of a panchromatic illumination quality detection method according to another embodiment of the present invention; image 3 shown, including the following processing steps:
[0148] S21. Continuously collect color images of the area to be detected; the collection is real-time collection or extraction from video; preferably, real-time collection; preferably, the received or collected image is an original image without digital processing;
[0149] S22. Extract one frame of the image collected at every interval A (A is greater than or equal to 0) frame; preferably, A=1;
[0150] S23. Divide the extracted image into M rows and N columns of sub-regions; each row has m pixels, each column has n pixels, m≥1, n≥1, m and n are preset; preferably, m=5 , n=5;
[0151] S24. The thresholds of each color component are set respectively (such as when the image uses RGB color separation, the upper thresholds corresponding to red, green...
