[0055] According to the first embodiment of the present invention, a kind of corner detection method based on neural network, it may comprise the following steps:
[0056] S1. Perform preprocessing on the collected image. The preprocessing may include one or more of denoising processing, grayscale processing, and normalization on the image as required.
[0057] S2. Perform edge extraction on the preprocessed image. Preferably, the edge extraction may use a Canny edge extraction method, so that the detected image is a binarized image including edges.
[0058] S3. Crop the image containing the edge into multiple sub-images with a size of m×n according to a fixed step size, and record the coordinate label of each sub-image in the original image. Wherein, the step size can be determined as required, preferably, the step size is smaller than n in the horizontal direction of the image to be detected, and smaller than m in the vertical direction of the image to be detected.
