【 摘 要 】

An interactive image pre-processing algorithm is proposed to solve the problem that the target object is not accurate and the calculation is time consuming when the space robot is in orbit. Firstly, the Grabcut algorithm is improved to identify the space object. The Gaussian filtering, edge detection, morphological processing and other methods are combined with Grabcut algorithm. Then the Hough transform algorithm is improved, and the straight line with similar slope is fitted, and the intersection of the straight line is obtained, which is the key point of the object to describe the spatial coordinates of the object. Through the experimental verification, the method proposed in this paper can meet the task of identifying the object of the space object, which can improve the accuracy and recognition speed of the object recognition and reduce the time taken to identify the space object.
