Abstract

The invention provides a multifunctional panorama video splicing method comprising steps of: acquiring stereo video stream data of different angles captured by multiple video cameras, GPS data, INS data, and 2DGIS data; determining whether GPS time and INS time are synchronous or not, a GPS position and an INS position are synchronous or not, and videos in various channels are synchronous or not; analyzing, compressing, analyzing and extracting, and storing video data and spatial positional information; calibrating data in each channel, processing and integrating video data, GPS data, GIS data, and INS data in a unified manner, and extracting spatial characteristic points with latitude and longitude information; and enabling characteristic point matching pairs to be accurate by using three-dimensional coordinates, automatically and preferably selecting a splicing parameter; and splicing the panorama video in real time. The method is an automatic preferably selecting technique based on image characteristic points, video matching splicing, and image splicing transformation parameters and achieves high-performance panorama video splicing by integrating the spatial positional information of the characteristic points.

Description

technical field [0001] The invention belongs to the field of image processing, in particular to a multifunctional panoramic video real-time mosaic method. Background technique [0002] Panoramic video stitching technology involves technologies such as computer vision, computer graphics, digital image processing, and some mathematical tools. Panoramas can express complete surrounding environment information, which is equivalent to what an observer can see when turning around from a fixed point of view. [0003] Panoramic video image stitching technology is to register adjacent frame images in a video to generate a panoramic image containing all the information of the video sequence. Panorama brings people a brand-new sense of real presence and interactive experience. It can be widely used in 3D e-commerce, such as online real estate display, virtual tourism, virtual education and other fields. important application. [0004] For real-time video panorama synthesis technolo...
