Summary: | The invention discloses a time-sharing overlapping plant image key feature region edge path acquisition method. The method comprises the following steps: 1, searching the edge of a night grayscale image; and 2, taking the edge as a precondition, and adaptively searching a plant image key feature region in the daytime color image. The step of finding the edge of the night grayscale image comprises the following steps: carrying out binarization processing on the grayscale image shot by night infrared light supplement; performing closed operation processing on the obtained binarized image; and after filling, extracting a target contour in the binarized image to obtain edges of a plurality of regions. The step of searching the plant image key feature region in the color image comprises the following steps: establishing a weight map for the color image; searching a path from an initial point to a free point; and freezing similar paths. According to the method, irrelevant backgrounds can be effectively shielded in |
