Abstract

The invention belongs to the technical field of optical precision measurement, and relates to a two-dimensional dynamic angle measuring and calibrating method and device of a scanning camera mirror. The two-dimensional dynamic angle measuring and calibrating method and device can be used for measuring and calibrating parameters of the scanning camera mirror in real time. According to the two-dimensional dynamic angle measuring and calibrating method and device, an infinite target generation system is used for generating an infinite target, the infinite target provides a target source for a scanning camera to be detected through the scanning camera mirror for detection, a two-dimensional dynamic angle measuring system is used for performing two-dimensional real-time measurement on the oscillation angle of the scanning camera mirror, a synchronous acquisition system is used for synchronously acquiring data of the scanning camera to be detected and data of the two-dimensional dynamic angle measuring system in real time, and the data of the two-dimensional dynamic angle measuring system are used for calibrating the scanning camera mirror. The two-dimensional dynamic angle measuring and calibrating method and device of the scanning camera mirror have the advantages of being high in speed, wide in range, free of contact and the like and provide an effective solution for measurement and calibration of the parameters of the scanning camera mirror.

Description

technical field [0001] The invention belongs to the technical field of optical precision measurement, and relates to a scanning camera swing mirror two-dimensional dynamic angle measurement and calibration method and device, which can be used for real-time measurement and calibration of scanning camera swing mirror parameters. technical background [0002] The scanning camera is a key component of the camera in high-altitude reconnaissance equipment such as satellites and early warning aircraft. Its performance directly affects the resolution of the satellite's earth observation and the size of the field of view. , Scanning uniformity (linearity), scanning angle repeatability, scanning linear segment time, effective scanning field of view, scanning frequency, etc. are calibrated with high precision to facilitate the stitching, calculation and fusion of camera images. In the design of a satellite scanning camera, the scanning performance of the swinging mirror is the core per...
