Zusammenfassung:The invention discloses a space target positioning method, and aims to solve the technical problems of large calculated amount, high processing cost, poor real-time performance and unsuitability for application in a complex space environment in a camera calibration process in the prior art. The method comprises: generating dense mark point data corresponding to images shot by a left camera and a right camera of a binocular vision system pixel by pixel by utilizing orthogonal angular points on a solar cell panel; dividing the obtained data into a training set and a test set; then, constructinga proper BP neural network, performing repeated training learning on the constructed BP neural network by using the training set, and performing error testing on a training learning result by using the test set until convergence; and finally, fitting a binocular vision measurement calculation model based on the training result of the BP neural network, and then directly obtaining the three-dimensional world coordinates of
