Video analysis-based space positioning method

Abstract

The invention relates to a video analysis-based space positioning method. The method comprises the following steps: 1, obtaining and storing coordinate information, parameter information and relevant attribute information of a plurality of cameras in a range; 2, obtaining and storing video data containing a target; 3, searching the video data containing the target according to the characteristic information of the target; 4, obtaining and storing the coordinate information of the target at every moment in real time according to the information of the position of the target relative to the cameras, and the position coordinate information, the parameter information and relevant attribute information of the cameras; and 5, obtaining the motion locus of the target according to the coordinate information of the target at every moment. The method fully utilizes the dense monitoring facility laid in the city scene, can rapidly position the accurate position of the target, can obtain the motion locus of the monitored target within a period of time, solves the accurate positioning problem in the complex city scene, and avoids the position description complexity existing in simple latitude and longitude positioning.

Description

【Technical field】 [0001] The invention relates to space positioning technology, in particular to a space positioning method based on video analysis. 【Background technique】 [0002] The spatial positioning methods in the prior art are often based on cameras tracking and positioning targets within their monitoring range. In the case of complex urban scenes and large-scale and fast-moving targets, the above-mentioned spatial positioning methods do not make full use of the dense monitoring equipment of urban scenes, and it is difficult to obtain the position of the target quickly and accurately, and it is difficult to obtain the position of the target within a period of time. motion track. 【Content of invention】 [0003] The present invention aims to solve the problems existing in the above-mentioned prior art, and proposes a spatial positioning method based on video analysis, which is used to obtain the movement track of a target within a certain range. The method includes ...
