Microminiaturization co-image face panoramic imagery technique

Abstract

A microminiaturized common image surface panorama imaging technique, wherein aspheric imaging lens and corner cube mirror constitute four identical imaging optical path rack and vertically fixed. The number of divided image surfaces by image surface coupler is same to the number of divided image surfaces by aspheric imaging lens and corner cube mirror. The three-dimensional space scene information obtained by aspheric imaging lens and corner cube mirror arrives the image surface coupler by the imaging optical path rack and the imaging surface of imaging device is divided into four same imaging areas in four quadrant using image surface coupler and the four path scene information synchronizes one path to image on the four imaging areas of image surface. Four images on the image surface respectively correspond space scene information on the four direction and are subjected to character matching and image mosaicking based on the overlap area between the two adjacent scene images, in order to obtain a intact space panoramic image. The invention has features of identical linearity, good resolution and real time performance, small aberrance, microminiaturization, particularly suitable for application with higher microminiaturization requirement.

Description

technical field [0001] The invention belongs to the optical imaging technology, and in particular relates to an imaging technology for realizing miniaturized panorama by using image plane segmentation and common image plane imaging methods. technical background [0002] With the development of image sensors and image processing technologies, many fields require real-time panoramic imaging of scenes in all directions in space, such as security monitoring, panoramic target recognition, etc. Rotation stitching, fisheye lens and catadioptric mirror are the main methods of panoramic imaging technology at present. Among them, the rotation stitching method can make the resolution of each image high, and the resolution of the whole panoramic image after stitching is also relatively high, and the image distortion is small, but it needs an accurate rotation mechanism, and the real-time performance is not strong; the fisheye lens method is an ultra-wide-angle The objective lens can ob...

Among them, the rotation stitching method can make the resolution of each image high, and the resolution of the whole panoramic image after stitching is also relatively high, and the image distortion is small, but it needs an accurate rotation mechanism, and the real-time performance is not strong; the fisheye lens method is an ultra-wide-angle The objective lens can obtain images with a large field of view, but the acquired images need to be additionally corrected by the algorithm, and the image distortion is large; the catadioptric panorama method can enable the multi-reflection surface system in the imaging system to obtain a larger field of view, reflection surface and refraction The surface is integrated together, the system is small, the structure is compact, and it is easy to realize miniaturization and integration. The disadvantage is that the optical structure design is complicated
