Embodiment Construction
[0036] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:
[0037] The invention discloses a real-time monitoring method of water level based on image processing, such as figure 1 As shown, the specific steps are as follows:
[0038] One, such as figure 2 As shown, fix a pole in the watershed to be measured, and make a red mark on the top of the pole. The image of the area where the landmark is located is collected in real time by the camera, such as image 3 shown.
[0039] 2. Use the object automatic detection technology in image processing to detect the images collected in (1), and extract the benchmark images exposed to the water surface, such as Figure 4 shown.
[0040] 1): Preprocess the benchmark image collected by the camera, perform color space conversion (LUV conversion) to obtain each image channel, calculate the integral map, and perform feature construction and extraction on the channel....
