[0019] A method for autonomously measuring the position and attitude of a tripod structure of solar panels on a non-cooperative spacecraft. The image processing steps are as follows:
[0020] (1) Use Canny operator to extract the edge of the image: smooth the image with a Gaussian filter, then use the finite difference of the first-order partial derivative to calculate the magnitude and direction of the gradient, then perform non-maximum suppression on the gradient magnitude, and finally use Double threshold algorithm to detect and connect edges;
[0021] (2) Perform average filtering to reduce pixel noise;
[0022] (3) Image binarization: that is, gray scale division, which refers to setting a gray value. If the gray level of the image itself is greater than it, it will be a bright spot, and if the gray value is lower than the set value, it will be Dark spots, so a binary image is obtained.
