进行图像的角点提取，方法是先通过Harris方法选初始点，然后对初始点进行Forstner算法进行筛选，最后得到图像角点。-The image of the corner detection, the method is to first select the initial point through the Harris method, and then point Forstner initial screening algorithm, the resulting image corne

Forstner算子，摄影测量重要算子，用于提取兴趣点-Forstner operator, photogrammetry important operator, used for extracting points of interest
