Abstract

The invention relates to a multi-optical-axis consistency detection device and method of a platform photoelectric device at any axial distance. The detection device comprises a semi-transparent semi-reflection mirror, a reflection mirror, a first position sensitive apparatus, a second position sensitive apparatus, an analog-digital converter, a CCD (charge coupled device) imaging assembly, an image collection card and a data control processing system. By adopting the detection device, an optical-axis deviation angle of each optical sensor of a detected platform photoelectric device can be calculated, the detection is not limited by the axial distance among the optical sensors, no cooperative target is needed, calibration and adjustment are avoided, the detection precision is high, the size is small, the weight is light, simplicity in operation can be realized, the automation degree is high, the online rapid optical-axis consistency detection requirement of multiple optical sensors of the platform photoelectric device in a field environment can be well met, and the popularization and application prospect is wide.

Description

technical field [0001] The invention relates to an axis measurement device, in particular to a device and method for detecting the consistency of multiple optical axes with arbitrary wheelbases for platform optoelectronic equipment. Background technique [0002] At present, the platform optoelectronic equipment integrated with multiple optical sensors integrating visible light (including low-light) imaging, laser ranging, and infrared thermal imaging has been widely used in various types of weapon systems. Combat tasks such as instruction, target tracking, and night imaging have significantly improved the shooting accuracy and combat effectiveness of weapons and equipment. It is of great significance to carry out multi-axis consistency detection for platform optoelectronic equipment to ensure the shooting accuracy of weapon systems.
