Abstract

The invention provides a target simulating system of a dynamic selenographic imaging sensor. The target simulating system comprises a target image generating unit, an image outputting unit and an optical transmission unit; the target image generating unit is used for generating a three-dimensional selenographic feature according to DEM (Dynamic Effect Model) data and remote sensing image data, and dynamically generating grayscale image data meeting the imaging requirement of the selenographic imaging sensor according to a selenographic illumination condition of the selenographic imaging sensor at imaging time and a position posture parameter of the selenographic imaging sensor at the time; the image outputting unit is used for displaying the grayscale image data generated by the target image generating unit on an LCD (Liquid Crystal Display) device; and the optical transmission unit is used for optically converting an image displayed on the LCD device, so that the image is rightly imaged on an imaging device of the selenographic imaging sensor.

Description

technical field [0001] The invention belongs to the technical field of aerospace imaging sensor testing, and is also applicable to imaging performance simulation tests of imaging sensors in space environments such as deep space exploration and planetary exploration. Background technique [0002] With the rapid development of aerospace technology, optical imaging sensors represented by cameras will be more and more widely used in the field of deep space exploration because of their large amount of information, flexible use, and high efficiency. In order to ensure the reliable operation of the imaging sensor in orbit, it is necessary to fully test its functional performance in all aspects on the ground, especially the verification of its optical imaging performance in the orbital working environment. [0003] At present, there are two main ways to verify the imaging performance of the optical head of the imaging sensor in the space environment at home and abroad: [0004] 1. ...
