Optical imaging alignment measurement device

Abstract

The invention relates to an optical imaging alignment measurement device, which can carry out high-precision determination on relative positions of two objects. The device comprises an area array CCD, an optical lens, a video processing circuit, an LED red light source and spherical reflectors. The position and the connection relation of each part are that the area array CCD, the optical lens, the video processing circuit and the LED red light source are arranged on a plane; the three high-reflectivity spherical reflectors are arranged on another plane; the red light source is used to illuminate the three spherical reflectors; the mass center of the three reflectors is the center of the plane; and the alignment of the two planes is completed by processing the imaging of a camera to the reflector, calculating a miss distance of the mass center and coordinates of images of the three reflectors by the video processing circuit, sending the numerical values to a control device, controlling the plane of the camera to move along the X, Y and Z directions to make the mass center and the center of the CCD target plane coincident, and moving the centers of three target image points to the predetermined CCD target plane coordinate. The measurement device is simple, and has high alignment precision, small volume and easy installation and application.

Description

technical field [0001] The invention relates to an optical imaging centering measuring device, which can determine the relative positions of two objects with high precision. Background technique [0002] In the field of missile artillery launching, the launching vehicle and the loading vehicle need to enter a fixed relative position, so a fast and accurate measuring device is required. [0003] Usually, the method used to determine the relative position of two objects is to use a high-precision theodolite to measure the fixed cooperative targets on the two objects respectively, but the measuring instruments used in this measurement method are expensive, have high requirements for use, and are easily damaged. The mobility is poor, and it is very difficult to apply it in the field of missile artillery launch. Other measurement methods have relatively large limitations in terms of accuracy and reliability. [0004] This invention is an alignment measurement device with low pr...
