Claim 8:
9. The digital detection system for predicting drug resistance of transgenic maize of claim 7, wherein the pixel ratio calculation module comprises:
an image pre-processing unit, configured to perform 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;
a second region determination unit, configured to determine the second region at the current moment according to the color image of the maize plant at the current moment;
a first region determination unit, configured to segment 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
a pixel ratio calculation unit, configured to calculate 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.
