Embodiment Construction

[0029] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the embodiments are not intended to limit the present invention.

[0030] The frame picture described in the present invention is the picture picture at a certain moment when the camera collects the image, that is, the frame picture is a subset of the collected image; the pixel point refers to the picture picture at a certain moment is further decomposed into a plurality of pixel point pictures, more A set of pixel points is a frame picture, that is, a pixel point is a subset of a frame picture.

[0031] Such as figure 1 As shown, an image mosaic system based on opencv includes: an image acquisition module, which is a multi-angle surveillance camera, used to rotate multiple circles at different elevation angles to collect video images, and use OpenCV to con...

Abstract

The invention discloses an opencv-based image splicing system and method. The system comprises an image acquisition module, a picture splitting module, an image caching module, an image processing module, a picture analysis module and a panoramic picture storage module. The method comprises the following steps: acquiring a plurality of video images of the same visual angle through a camera, and converting a video stream into frame pictures by adopting OpenCV; further disassembling each frame of picture into pixel points; sending the key value of each frame of picture and the disassembly of the pixel points of the frame of picture to a picture storage server for caching after being bound; based on a panoramic video stitching algorithm of OpenCV, performing pixel stitching on the acquired images to generate a panoramic picture; calling a picture analysis tool, and detecting whether a picture imaging effect is abnormal or not by analyzing related characteristics of the panoramic picture; and storing the spliced panoramic image into a distributed file system for subsequent viewing or calling of a specific application. According to the method, the imaging effect of the picture is analyzed, and the imaging effect of the whole image is better.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to an image stitching system and method based on opencv. Background technique [0002] OpenCV is a cross-platform computer vision and machine learning software library released under the BSD license (open source), which can run on Linux, Windows, Android and Mac OS operating systems. It is lightweight and efficient-consists of a series of C functions and a small number of C++ classes, and provides interfaces for languages ​​such as Python, Ruby, and MATLAB, and implements many general algorithms in image processing and computer vision, including a series of image processing In terms of basic methods, some methods can be used directly. In addition, we can also perform a series of optimization operations on the basis of OpenCV's native code and interface. [0003] The existing image stitching method only deals with how to stitch each frame of the image, but does ...
