The Structure Optimization Of Multi-camera Imaging And The Research Of Image Stitching Algorithm

With the continuous development of digital image processing and microelectronics technology, large field of view camera technology is increasingly taken seriously, it is widely used in civilian and military industries, such as:meeting rooms, airports, railway stations, car parks, workshops and other large open areas monitoring; panorama car driver assistance systems; tank panoramic patrol system; maritime patrol search system; helicopter search system. This shows that large field of view imaging technology has broad applications and prospects.At this stage, how to get a larger perspective, higher quality, better real-time panorama has become a new and heat research topic. General questions are:what kind of wide-field imaging system and how the panorama presented.In this paper, the following design and research are given to deal with these issues.1. This paper presents a low-price, small size and light weight wide field of view imaging system devices, which is composition of a plurality of cameras. In this device, the camera division multiple ring distributed and are distributed on a flat. The whole device is compact structure, simple and small. The camera and the circuit board to achieve the shortest connection to ensure that the high frequency data transmission quality. The system can achieve hemispheric field of view imaging surface.2. In this paper, calibration method section of CMOS is studied, including:the detection and treatment of bad points and dark current as well as the output of non-uniformity correction. We do this in order to collect picture, which is close to the real scene.3. In this paper, the image registration method with SIFT features, eliminating the mismatching points with RANSAC method and fusion method with weighted average are studied. With the above image mosaic method, fusion splicing of 5 images from different cameras are treated in the Matlab software platform.In summary, a new wide-field image capturing device and image mosaic method has been proposed and studied.
