Problems solved by technology

However, the existing interactive large-scale space (above 800m2) spatial positioning uses laser scanning and light sensor reception to determine the spatial position of objects. This type of spatial positioning method often has relatively large measuring equipment, long measurement time and inability to measure in real time. problem, the scope of application is greatly limited

Abstract

The invention provides an interactive large space positioning algorithm, and relates to the technical field of space positioning. The method concretely comprises the following steps: 1, allowing a camera to emit an external trigger signal to make three cameras simultaneously acquire a frame of data, and transmitting the data a computer through a wire; 2, respectively calculating the two-dimensional coordinates of all mark points in a three-frame image through calling a distortion processing function and calculating a gravity solving center function; 3, carrying out stereo vision matching on all the mark points through a stereo vision matching technology, and substituting the matched two-dimensional points to the three-dimensional coordinates of all the mark points in trigonometry; 4, calling function display to display all the mark points; and 5, judging whether positioning ends or not, and jumping to step 1 and continuously acquiring the image if no end instruction is received. The positioning range, the device cost and the system real-time performance of the algorithm are greatly improved, and the real-time performance and the accuracy of the algorithm can meet the multi-particle positioning requirements of the interactive large space.

Description

technical field [0001] The invention relates to the technical field of spatial positioning, in particular to an interactive large-scale spatial positioning algorithm. Background technique [0002] The stereoscopic vision technology of objects has been one of the focus and hotspots of computer vision research in recent years. Its goal is to convert the two-dimensional images collected by the camera into three-dimensional stereoscopic information. Using these three-dimensional data, we can simulate various simulation scenes and intelligent systems, such as virtual object demonstrations in games and scenes, and so on. With the development of computer science and the increasing demands of daily life, fast and accurate 3D reconstruction technology will continue to develop. However, the existing interactive large-scale space (above 800m2) spatial positioning uses laser scanning and light sensor reception to determine the spatial position of objects. This type of spatial positioni...
