Abstract

The invention discloses a device and a method for calibrating the dynamic tracking precision of a photoelectric tracking system. The device comprises a beacon light subsystem used for generating beacon light, a high-speed image acquisition system and a processing subsystem, wherein the beacon light subsystem comprises a high-precision laser target simulator, a laser target controller, a first computer and a target plate; the high-speed image acquisition system comprises a high-speed camera; and the processing subsystem comprises a second computer. The beacon light subsystem consisting of a solid laser, a beam expander, a fast tilting mirror and a reflecting mirror is used for generating the beacon light to the target plate and can simulate targets with a plurality of motion modes and movement speeds through faculae, so that the precision of equipment can be tested persuasively. The faculae are acquired by the high-speed image acquisition system and the high test precision can be obtained by using a high-speed digital image processing technology, so that the photoelectric tracking system is quickly and accurately calibrated according to the measurement of the tracking precision.

Description

technical field [0001] The invention relates to the field of optical metrology, in particular to a dynamic tracking accuracy calibration device and method for a photoelectric tracking system in image processing. Background technique [0002] For the dynamic tracking accuracy index of the photoelectric tracking system, a lot of research has been done at home and abroad, and the gap between domestic and foreign countries is relatively large. Due to the military sensitive technology involved, there are not many detailed public reports. [0003] According to the existing public information, the United States has deployed hundreds of optical and photoelectric measurement equipment in the Baisha shooting range. Its data processing capability is strong and the measurement network is advanced, which can be used to detect any photoelectric tracking measurement equipment, but there are very few specific technical indicators. disclose. Our country has also done a lot of work on the ca...
