Abstract

The invention relates to a system and method for automatically calibrating the parallelism of optical axes of multi-spectral multi-optical-axis optoelectronic devices. The axis automatically-calibrating method can be applied to the optoelectronic devices of helicopters, unmanned aerial vehicles, fixed wing aircrafts, vehicle-mounted platforms, ship-based platforms and the like, and the adverse factors of poor axis calibrating accuracy, complex procedures, poor maintaining performance, high cost and the like caused by the manual axis calibrating scheme of an existing ground axis calibrating instrument are overcome. Short wave infrared band laser spot tracing instruments, external characteristic targets and the video picture processing technology are adopted for achieving automatic calibrating of the optical axes of the multi-spectral optoelectronic devices. On the premise that the system complexity is reduced, rapid and automatic calibrating of the optical axes of sensors is achieved.

Description

technical field [0001] The invention belongs to the field of optoelectronics, and relates to a system and method for automatic calibration of optical axis parallelism of multi-spectrum multi-optical axis optoelectronic equipment. Background technique [0002] With the development of photoelectric detection technology, more and more photoelectric sensors are used in photoelectric stabilization equipment on platforms such as helicopters, unmanned aerial vehicles, fixed-wing aircraft, vehicles and ships. Photoelectric sensors include TV sights, low-light TVs, mid-wave infrared thermal imaging cameras, long-wave infrared thermal imaging cameras, laser rangefinders / illuminators, etc., and the spectral coverage ranges from visible to infrared. In order to improve the capture, tracking and aiming accuracy of the photoelectric stabilization equipment, as well as the irradiation accuracy of the laser rangefinder / illuminator, a high degree of parallelism must be maintained between the...
