| description | The invention discloses a large-aperture camera laboratory geometric distortion calibration method, and belongs to the technical field of spaceflight optical remote sensors. The method comprises the following steps: firstly, building a camera geometric distortion accurate calibration demonstration verification environment, wherein a target ball of a laser tracker is positioned on an infinite focal plane of a camera main body lens; rotating the angle of the plane mirror for multiple times in the full view field range of the camera main body lens, positioning the target ball at the infinite focal plane of the camera main body lens after each angle rotation, and testing the current rotation angle of the plane mirror and the position of the target ball; and resolving the principal point, the principal distance and the distortion of the camera main body lens according to each obtained rotation angle of the plane mirror and the target ball position. Through application of the method, high-precision calibration of g |
