Full space-time three-dimensional visualization method

Abstract

The invention provides a full space-time three-dimensional visualization method. The method includes the following steps: real-time video data collected by a camera are packaged and converted in terms of a format; real-time fixed angle video data are spliced and fused in 3D GIS spatial data, so as to form a panoramic three-dimensional video; an event target of the panoramic three-dimensional video serves as a driving force to realize a camera cooperative pursuit; according to a result by the packet and format conversion, the real-time video data are stored in a storage device to form history video data; and the fixed angle video data are spliced and fused in the 3D GIS spatial data, so as to realize the full space-time three-dimensional visualization display of the history video. In addition, in order to realize video intelligent analysis and realize multidimensional data fusion and three-dimensional visualization display in a full scene, the invention also provides a full scene video intelligent analysis method and a multi-type data full space-time three-dimensional visualization method. The full space-time three-dimensional visualization method provides an effective means for the macro command monitoring, overall correlation, and comprehensive scheduling, and is high in applicability.

Description

technical field [0001] The invention relates to the field of computer graphics and imaging, and in particular, relates to a full-time-space stereoscopic visualization method. Background technique [0002] With the rapid development of information technology, various application equipment, such as scanners, surveillance cameras, alarms, sensors, etc., have collected massive amounts of data, which include various information such as spatial location, text, image, and sound. The increasing amount of data has brought great challenges to data management. Based on the fact that more than 80% of people's information is obtained visually, visualization technology has made great progress. At present, a large number of surveillance cameras, alarms, sensors, etc. have been installed in cities. Since the video images captured by multiple cameras are discrete and independent Yes, the correlation between each screen is poor. At the same time, intelligent analysis based on video surveill...

Problems solved by technology

[0020] To sum up, video surveillance technology has experienced the development process from local monitoring to panoramic observation, from planar video surveillance to stereoscopic video surveillance. At present, some important achievements have been made in video surveillance technology for large scenes, but generally speaking, the current At home and abroad, there is no technology that can be applied on a large scale to conduct global monitoring of the monitoring area and a general technology that can perform intelligent analysis of full-scene video in the monitoring area
