Abstract

The invention relates to a spatial information technology, in particular to a video positioning system and method. The method comprises the following steps: establishing a mapping relationship between target pixels and spatial coordinates of the target pixels through an interactive operation and data transmission between a mobile terminal and a monitoring camera; performing processing through spatial calibration software to automatically finish spatial coordinate calibration of a video monitoring range; and building a video map in order that target pixel points on a monitoring video matrix have corresponding spatial coordinate values, thereby realizing spatial positioning of any dynamic/static target pixel within the monitoring range. Meanwhile, space-time coordinate calibration is performed semi-automatically through WIFI (Wireless Fidelity) functions of a mobile terminal positioning device and a wireless router, so that conventional manual processing is replaced; the working efficiency is increased; and the cost is reduced.

Description

technical field [0001] The invention relates to spatial information technology, in particular to a video positioning system and method. Background technique [0002] The integrated deployment of wireless routers and cameras has become the development trend of urban infrastructure, such as WIFI cameras and other products and patents. The combination of the two can not only share resources and save costs, but also can transmit data and function interoperably. [0003] Currently, surveillance cameras are managed by number and do not have precise spatial positioning capabilities. On the other hand, to carry out camera measurement and positioning, it is necessary to manually calibrate the camera (including: selection of control points-spatial mapping-coordinate input-coordinate conversion, etc.), the process is complex, costly, and the cycle is long, so it is difficult to complete automatically. [0004] Patent application number 201310443078.6 provides "a method for adding geo...
