[0031] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but the embodiments should not be construed as limiting the present invention.
[0032] See figure 1 The method for detecting a limb conflict event of the present invention consists of three steps: motion image processing, rough judgment of limb movements, and precise detection of limb movements. The specific implementation method of the three steps is as follows:
[0033] 1) Moving image processing
[0034] See figure 2 , According to the characteristics of no obvious changes in adjacent frames, filter out the parts with no obvious motion in the image. The specific steps are as follows:
[0035] 1.1.1) Obtain the k-1, k, and k+1 three continuous images from the surveillance video sequence, convert them into grayscale images, and use linear transformation to convert the grayscale of all pixels in the grayscale image. The degree value is transformed int...
