全景光学环带凝视成像技术

Panoramic optical annular staring imaging technology

提出一种无需转动镜头,一次性瞬时完成周围360°目标成像的全景光学环带凝视成像技术。该技术采用平面圆柱投影方法,可实现超半球成像。分析了全景环形透镜PA L的成像特性,给出全景光学设计实例,利用所完成的原理样机实现了动态全景数字图像处理。成像结果表明该技术在管道测量、医用内窥检查、全景监控、周视监测等领域具有广阔的应用前景。

A panoramic optical annular staring imaging technology was presented, which could be used to image the surrounding 360° scene at one time without rotating the optical system. Imaging characteristics of the panoramic annular lens was analyzed and a design example was given. According to the design, a prototype of the panoramic annular staring optical system had developed and panoramic ring images could be obtained. With digital image processing, the panoramic image could be expanded with self-written software. Potential application of this technology in industry and defense was discussed.
