The embodiments of the present invention relate to a drag-based stereo measurement unit, a system and a space target measurement method. The method includes: calibrating a camera in a camera group and a camera in a space target detection system; using the space target detection system to perform a field of view Scanning and laser ranging, and determine the orientation and distance of the space target based on the scanning results of the field of view; determine the release angle of the towed stereo measurement unit according to the orientation and distance of the space target, and release according to the release angle; according to the towed stereo measurement unit The initial values of the pose parameters and structural parameters of the space target are calculated from the image data obtained by the camera group in . The invention performs multi-angle imaging to reconstruct the space target in full shape and three-dimensional, and has high accuracy; the dragging structure can avoid erroneous collision with the space target and improve the safety of measurement.
Description
technical field [0001] The invention relates to the technical field of space target detection, in particular to a towable stereo measurement unit, system and space target measurement method. Background technique [0002] The three-dimensional topography structure of a space target, especially the topography structure of the corresponding load on the target, can effectively reflect the performance characteristics and working status of the space target. For example, the power can be obtained from the inversion of the size of the solar panel, the radar performance can be obtained from the inversion of the size of the antenna structure, the maneuverability can be obtained from the shape and size of the booster, and the inversion can be obtained from the size of the camera structure. Imaging performance, temperature and electromagnetic properties can be inverted to obtain working conditions, etc. [0003] The existing space-based space target stereo measurement method is based o...
