Background
Space observation devices are commonly used for space pose determination, image processing, automatic identification of targets, real-time tracking, and the like. In order to evaluate the target identification, tracking capability and other indexes of the space observation equipment, before the equipment leaves a factory, the equipment needs to be strictly tested and evaluated.
The target simulation usually adopts an optical simulation mode at present. The optical simulation apparatus is usually designed for specific parameters of the observation camera, and when the parameters of the observation camera are changed, the optical simulation apparatus mostly needs to be redesigned or changed, so that the universality of the optical simulation apparatus is deficient. When the optical simulation mode is adopted to test the image processing module of the space observation equipment, the optical simulation device, the observation camera and the image processing module are required to be connected and cooperatively work, if the observation camera cannot be developed before the image processing module is tested, the test progress of the image processing module may be influenced, and thus the optical simulation mode has stronger dependence on the observation camera. In addition, the optical simulation method generally has a long development period and a high development cost.

Further, the image transmission module supporting software based on the CPCIE includes a module driver and a module application API. The module driver uses a drive framework design; and the module application API is packaged in a dynamic link library mode and is called by target simulation software.
Further, the image transmission module based on the CPCIE sends the external pulse per second signal to target simulation software of the target simulation computer in real time in a message interrupt mode through the CPCIE interface. In addition, the target simulation software transmits the generated target simulation image to the image transmission module based on the CPCIE through the CPCIE interface.
Furthermore, the image transmission module based on the CPCIE is connected with the image processing module of the space observation equipment through a parallel LVDS interface or a Camera Link. The parallel LVDS output interface is divided into two paths, one path is output to the image processing module, the other path returns to the image transmission module based on the CPCIE, and the returned target simulation image is uploaded to target simulation software of the target simulation computer through the image transmission module based on the CPCIE and used for displaying and verifying the correctness of the output image.
Furthermore, the image transmission module based on the CPCIE adopts FPGA hardware programming, selects a data sending and receiving mode based on DMA (direct memory access) for ensuring the real-time performance and reliability of data transmission, allocates enough ping and pong spaces, and ensures the seamless buffer of data and the continuity of data flow.

2) Only one path of target image is simulated and output through a Camera Link interface;
3) And the simulation of simultaneous output of two different target images through a parallel LVDS interface and a Camera Link interface is supported.
Furthermore, the target simulation software can flexibly set model parameters such as camera parameters, target characteristics, a target motion mode, a platform star motion mode, a turntable motion mode and the like, and automatically generate corresponding target simulation images according to the parameters.
Further, the target simulation image generated by the target simulation software is a simulation image in which a noise image, a star background image and a plurality of target images are superimposed. The analog image may be a still image or a moving image.
According to the technical scheme, the embodiment of the invention has the following advantages:
