Method and system for generation of three-dimensional panoramic image based on zooming stereoscopic vision

Abstract

The present invention provides a method and a system for generation of a three-dimensional panoramic image based on zooming stereoscopic vision. The method employs two-dimensional images shot in different focal lengths to perform accurate image processing and analysis, employs an algorithm to calculate three-dimensional point cloud data of the image and performs point cloud data compaction, registration and splicing to finally generate a three-dimensional panoramic image. The system comprises two portions consisting of hardware and software, wherein the hardware comprises a monocular zooming image collection device, a storage device and a processor, and the software portion comprises an image processing program, a matching program and a splicing program. The implementation method can perform camera calibration, and a point cloud splicing method capable of graying, image enhancement, image feature extraction, dense matching, three-dimensional point cloud calculation, three-dimensional monocular vision can perform three-dimensional reconstruction of the image; and moreover, a mode is broken that a traditional camera shooting angle cannot satisfy demands, and the method and the systemfor generation of the three-dimensional panoramic image based on zooming stereoscopic vision can perform omnibearing appearance of basic construction of a target object.

Description

technical field [0001] The invention belongs to a monocular stereo vision system, and more specifically relates to a method and system for generating a three-dimensional panoramic image based on zoom stereo vision. Background technique [0002] With the rapid development of computer technology, people can obtain information through different ways such as vision, smell and hearing. Images play an important role in human perception, and a wealth of information can be obtained through images. With the continuous pursuit of the amount of visual information, the application research of panoramic images has been highly valued in the fields of artificial intelligence and machine vision. Panoramic images are widely used in virtual reality, geographic scene reconstruction, aerospace, medicine, etc. You can observe the panorama of streets on Baidu Maps. The Chang’e-3 lunar probe uses a panoramic camera to collect panoramas around the probe, and synthesizes a large-angle panorama of ...
