Problems solved by technology
[0004] The technical problem solved by the present invention is: for the problem that the layout of the sensor on the star and the field of view analysis method are difficult to meet the layout requirements of the surveillance camera, a method for the layout of the surveillance camera and the field of view analysis of the moving parts on the star is provided. Establish the virtual field of view of the surveillance camera to intuitively present the on-orbit imaging picture of the surveillance object, realize the follow-up of the virtual field of view of the surveillance camera, adjust the camera field of view conveniently, and conduct field of view analysis and illumination analysis to evaluate the surveillance effect. To determine the installation position of the surveillance camera on the star

Embodiment Construction
[0016] like figure 1 As shown, the definitions of several coordinate systems are first given as follows:
[0017] The satellite mechanical coordinate system is defined as follows:
[0018] Coordinate origin O A : Located in the mechanical separation plane between the lower end frame of the satellite and the launch vehicle, coincident with the theoretical center of the interface of the docking frame of the satellite and rocket;
[0019] o A x A Axis (rolling axis of the satellite): through the origin O A , which is parallel to the theoretical normal direction of the east plate of the satellite, and the positive direction is consistent with the outer normal direction of the east plate;
[0020] o A Z A Axis (the yaw axis of the satellite): through the origin O A , which is parallel to the axis of the satellite bearing tube, and the positive direction points to the direction facing the ground;
[0021] o A Y A Axis (the pitch axis of the satellite): with O A x A Axis...

The invention discloses a layout method of a satellite moving part monitoring camera. In order to solve the problem that a layout and view field analysis method of a satellite sensor cannot meet the layout requirement of a monitoring camera, a method depending on establishment of a physical view field merely is changed, and the virtual view field follow-up of the monitoring camera is realized by establishing a virtual view field of the monitoring camera to visually present an on-orbit imaging picture of a monitored object, so that the view field orientation of the monitoring camera can be adjusted conveniently, the follow-up of a three-dimensional model and the virtual view field of the monitoring camera can be realized, the layout of the monitoring camera can be completed, final monitoring camera layout information can be automatically output, view field analysis and illumination analysis can be carried out, the monitoring effect is evaluated, a satellite monitoring camera installation position is determined, and the efficiency and quality of layout of the satellite moving part monitoring camera can be improved greatly.
Description
technical field [0001] The invention relates to a layout method of monitoring cameras used to monitor the moving process of moving parts on a spacecraft. Background technique [0002] With the development of communication satellite technology, various large-scale deployable moving parts are increasingly used in communication satellites, and these large-scale on-board moving parts often require multiple steps to be deployed in place, and the on-orbit deployment process is complicated and technically difficult larger. In order to reduce the risk during the deployment of moving parts and improve the ability to deal with abnormal situations, the communication satellite has set up a monitoring subsystem to monitor the deployment process of moving parts and assist ground personnel to observe the deployment of moving parts. In case of abnormality, the cause of the failure can be judged through the monitoring subsystem, which provides a basis for the ground to adopt an emergency pl...
