A novel method of fast dynamic optical image stabilization precision measurement based on CCD
چکیده انگلیسی

Dynamic image stabilization precision is a key technical indicator in optical image-stable device, however, the fast dynamic test is difficult to implement. A novel fast dynamic image stabilization precision testing system for optical image-stable instrument is developed. The large-aperture collimator with the designed cross divisional board is used to simulate the infinity goal. A motion simulator with six-degree of freedom is adopted to simulate the moving state of the installed image-stable instrument. Combined with the optical lens designed in accordance with the analysis of the whole optical system in detail, the high speed camera installed behind the eyepiece lens of the measured device acquires images rapidly and real-timely. The local energy maxima center of the cross light spot can be obtained accurately through the proposed fast image stabilization precision test algorithm on the basis of Hessian matrix. The actual test results show that the test error of dynamic image stabilization in the proposed method of this paper is less than 0.7″, and the time of the frame image acquisition and processing is not more than 10 ms, which demonstrates the effectiveness of the test equipment and algorithm.
