Multi-lens panoramic stitching control method and multi-lens panoramic stitching control device

Abstract

The invention provides a multi-lens panoramic stitching control method and a multi-lens panoramic stitching control device. The panoramic stitching control method comprises the following steps: firstly, a multi-channel video of a panoramic camera is read, focal length and an included angle of each lens are regulated by a motor according to vision scope and monitoring distance to be monitored to ensure that a part of superposed area is arranged between adjacent pictures. And then, after the focal length is adjusted, the included angle between lenses is correspondingly regulated to carry out space matching alignment onto a superposed video sequence, and effect of forming a large-viewing-angle high-solution continuous image containing video sequence information is realized through exposure fusion.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a method and device for controlling multi-lens panorama splicing. Background technique [0002] Most of the current multi-lens panoramic stitching cameras use 2-8 lenses of the same specification to be mounted on a specific structure, so that there is a certain angle between the lenses. When the focal length is fixed and the angle is fixed, what we can see The field of view and range of seeing are also fixed, and cannot be adaptively adjusted according to the needs of monitoring. At the same time, in the stitching process, the common method is to extract the feature points in each image, and then perform matching, and use the matching pairs to calculate the perspective transformation matrix, so as to map each picture to the panoramic image. [0003] In practical applications, in order to reduce the pixel loss caused by excessive overlapping, the overlapping parts between ...

Problems solved by technology

[0003] In practical applications, in order to reduce the pixel loss caused by excessive overlapping, the overlapping parts between the screens will be minimized during design. If the scene is relatively simple indoors, when splicing multiple videos, it may not be possible to find enough The matching is unsuccessful but the stitching is unsuccessful; outdoors, the environment is unknown, and there is often no ideal stitching environment. At this time, whether the focal length, included angle is fixed or adaptive adjustment, it is difficult to use a multi-lens panoramic stitching camera.
