Abstract

The invention provides a six-camera around looking-based cylindrical panoramic generation device and method. The device comprises a regular hexagonal prism enclosure; six cameras are horizontally and outwardly arranged at the centers of the six side surfaces of the regular hexagonal prism; and the six cameras are focus-fixed fisheye cameras with 90-degree horizontal view angles. The method comprises the following steps: capturing images of the six cameras simultaneously; carrying out distortion correction on the six images by using a reverse division model; carrying out cylindrical projection on the six corrected images; carrying out feature detection and matching on the adjacent images with superposed areas by using an SIFT feature point detection algorithm; calculating the image translation splicing parameters and determining the sizes of the superposed areas through the optimum matching point; carrying out image splicing and fusion simultaneously; and carrying out smooth transition on the public area by using a slow-in slow-out fusion method so as to finally obtain the naturally transitioned cylindrical panoramic images. According to the device and method, the natural panoramic images of 360-degree view can be efficiently generated, so that the device and method are suitable for panoramic monitoring.

Description

technical field [0001] The invention relates to the fields of image processing and machine vision, in particular to a device and method for generating a cylindrical panorama based on a six-camera look-around. Background technique [0002] Visual perception is one of the most important ways of obtaining information. With the development of society, the demand in the monitoring field is getting higher and higher, especially in large-scale areas such as airports, railway stations, intersections, and commercial streets. If a single camera is used, multiple monitoring points are required due to the small field of view. Collaboration requires monitoring personnel to switch videos constantly for observation, but this is easy to make people tired. The use of panoramic imaging technology can obtain the scene information of a single viewpoint in the surrounding 360-degree viewing direction, so that the observer can perceive the changes of the surrounding scene faster and more accurat...
