The basic composition and functions of imaging parameters of a space camera were introduced.The impact of defective imaging parameter values on the imaging quality was analyzed and the risk of sampling test method for imaging parameter setting was analyzed by applying the mathematical method.On an automatic testing system,a method and a system to achieve a comprehensive verification for setting imaging parameters were proposed to solve the contradiction between test coverage and test efficiency.The method and the system were used to verify the functions of imaging parameter setting of the space camera.Experiment result shows that the proposed method can realize a comprehensive verification for setting imaging parameters of the camera,the test time is shortened to 40ms for each test case and that is about 50min for all systems.The method is able to effectively verify the function of setting imaging parameters and can meet the test requirements of zero quality defects.
