Claim 2:
3. The digital detection method for predicting drug resistance of transgenic maize of claim 1, wherein the step of calculating a pixel ratio of the maize plant at the current moment according to the RGB image at the current moment comprises:
performing a binarization, image filtering, noise removing and masking processing on the RGB image at the current moment to extract a color image with only the maize plant at the current moment;
determining the second region at the current moment according to the color image of the maize plant at the current moment;
segmenting the color image of the maize plant at the current moment by an Otsu method to obtain the first region at the current moment; and
calculating the pixel ratio of the maize plant at the current moment according to the pixel point number in the first region at the current moment and the pixel point number in the second region at the current moment.
