Abstract

The invention provides a camera position calibration method and a device. The method comprises steps of obtaining vehicle track information of a target vehicle when running on a preset route; obtaining snapshot information of the target vehicle by a camera arranged on the preset route during the running processes of the target vehicle; and determining longitude and latitude information of all cameras arranged on the preset route according to shooting time of each of snapshot pictures, identifications of cameras for shooting the snapshot pictures, the longitude and latitude information in various running positions and time information corresponding to the running positions. In this way, operation of information collection can be simplified; information collection efficiency is increased; and effects on public security during the information collection process can be avoided.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a camera position calibration method and device. Background technique [0002] The video monitoring technology based on GIS (Geographic Information System, geographic information system) electronic map has been widely used in the traffic and public security system to track illegal vehicles and deal with the police situation around the camera. [0003] And use electronic map to monitor, need to demarcate the position of each camera (comprising bayonet camera and electric police camera) on electronic map in advance. However, currently installed cameras generally do not have a GPS (Global Positioning System, Global Positioning System) positioning function, that is, the latitude and longitude information of the cameras cannot be obtained directly. Then the problem of how to obtain the camera position needs to be solved urgently. [0004] The currently adopted solution is g...
