A Fast Imaging Method of Camera Focal Plane Charge Coupled Device

Abstract

The invention provides a quick imaging method of a camera focal plane charge coupled device. According to the method, firstly, an optic axis of a camera is made to be the same as an optic axis of a collimator in height, the focal plane of the collimator is converted into 90-degree reflex focal plane, a cross-shaped scribed line target is arranged, then two carat lights are arranged on the position where a 90-degree reflex focal plane light source is placed, a black diaphragm is placed on a second focal plane, the horizontal angle and the pitching angle of a two-dimension rotating table are adjusted, the converged light spots formed by the light beams emitted by the two carat lights are located on the camera infinity focal plane charge coupled device, and finally, the first carat light is converted into the a camera lens to conduct real-time imaging on the center of the cross-shaped scribed line. By means of the quick imaging method, the position relation of the camera and the collimator and the position relation of the carat lights and the camera lens can be determined quickly and precisely, and thus quick imaging of the camera focal plane charge coupled device on the collimator infinity position is achieved.

Description

technical field [0001] The invention relates to a fast imaging method, in particular to a fast imaging method for a camera focal plane coupling device, which is suitable for fast imaging of a camera focal plane coupling device in the multi-camera system integration test process of an aerospace optical surveying and mapping camera, and belongs to aerospace optics field of remote sensor technology. Background technique [0002] With the widespread demand for real-time stereoscopic mapping images, surveying and mapping cameras generally use two or three cameras for imaging, and realize stereoscopic mapping by imaging the same scene on the ground at different shooting times with multiple cameras. Therefore, for a surveying and mapping camera that uses a combination of multiple line array cameras, in addition to the conventional internal orientation element parameters such as the principal point, principal distance, and distortion that need to be precisely calibrated, it is also ...
