The invention relates to an optical axis catadioptric monitoring device. The device comprises a detector assembly, a first reflection assembly, a second sleeve and a catadioptric assembly, wherein a first gear transmission assembly driven by a first motor is arranged at the joint of the first reflection assembly and the second sleeve; a second gear transmission assembly driven by a second motor isarranged at the joint of the catadioptric assembly and the second sleeve; a prism assembly capable of rotating and swinging is arranged in the catadioptric assembly; the detector assembly is connected with the first reflection assembly and is adjustable in position, and the detector assembly can realize replacement and position adjustment of the camera, the laser and the light source; the opticalaxis generated by the detector assembly realizes three-level precision adjustment of the optical axis through mutual cooperation of reflection adjustment of the first reflection assembly, reflectionadjustment of the second sleeve, rotation refraction adjustment of the catadioptric assembly and deflection refraction adjustment. Compared with the prior art, 360-degree large-range optical axis adjustment and sub-micro-radian precise optical axis pointing can be achieved, and imaging, tracking and lighting of a monitored object can be achieved at the same time.
Description
technical field [0001] The invention relates to the technical field of photoelectric tracking, in particular to a monitoring device based on optical axis catadioptric reflection. Background technique [0002] With the advent of the era of artificial intelligence, scene monitoring technology has been widely used in security monitoring, traffic management, ground search and rescue, military reconnaissance and other fields. Large-scale optical axis adjustment and high-precision optical axis pointing have always been the beautiful vision pursued by monitoring technology. However, in traditional photoelectric tracking monitoring systems, large-scale optical axis adjustment and high-precision pointing are a pair of conflicting indicators, which restricts monitoring. further development of technology.
