Abstract

An omnibearing visual transducer of blind angle free type is prepared for setting catadioptric lens at top of transparent external cover, arranging an opening at bottom center of said external cover, setting said transparent external cover on support frame, arranging video camera head on focus point of catadioptric lens and setting said catadioptric lens and transparent external cover as well as video camera head to be on the same axle coaxially.

Description

(1) Technical field [0001] The invention belongs to the application of optical technology, computer image processing technology and network communication technology in the field of remote monitoring. It is mainly suitable for intelligent transportation, video fire detection, and elevator safety protection, and is also suitable for monitoring Monitoring, anti-theft monitoring of supermarkets and stores, etc.), video conferencing, mobile phone camera, introduction of city scenery and scenic spots, distance education, automatic navigation and positioning, and medical and other global video information acquisition fields, especially an all-round visual sensor. (2) Background technology [0002] Most imaging systems in use today consist of a video camera (or still camera) and a lens. The projection imaging model of most lenses is the perspective of a single projection center. Because of the limited size of the imaging device (such as a CCD array) and the blocking around the lens...
