A multi-spectral binocular photoelectric equipment optical axis parallel digital calibration system is designed. The use of parallel light tube to produce infinity white light, glimmer, infrared target, parallel light through binocular optical equipment, optical axis translation device, the two light rays incident on the area array CCD, the target image by CCD, image acquisition card into digital The image information is sent to the computer, and the optical axis error is obtained by software algorithm. The optical axis calibration scheme is given with reference to the established mathematical model of optical equipment, and the optical axis parallelism correction is completed by using aided tools. The system is suitable for a variety of binocular optoelectronic equipment, to achieve automatic detection, and gives the amount of digital optical axis error, with good versatility and scalability.
