Embodiment Construction

[0037] At present, it is generally used to manually enter the position of the camera to solve the problem that the camera cannot be positioned. However, if the operator is not familiar with the geographical location, there will be a high error rate, and the efficiency of manual operation is low but the cost is very high. High, so it is not suitable for positioning when the number of cameras is large.

[0038] In order to solve the problems existing in the prior art, the present invention provides a camera positioning method and device, which can analyze the geographical location information of the camera in the road network information by extracting the road network information from the name of the camera to be positioned, so that according to the obtained The geographic location information of the camera is used to determine the position of the camera in the electronic map. Therefore, it can solve the positioning problem of the camera without latitude and longitude informatio...

Abstract

The invention provides a camera positioning method and device. The method is applied to an electronic map-based video monitoring system. The method includes the following steps that: the name of a camera to be positioned is obtained; road network information is extracted from the name of the camera to be positioned, wherein the road network information contains the geographical position information of the camera; and the position of the camera to be positioned in an electronic map can be determined according to the geographical position information. With the method and device of the invention adopted, problems in positioning cameras without longitude and latitude information in an electronic map can be solved, and therefore, influence on monitoring work caused by incomplete position display of the cameras in the electronic map can be avoided; and the method and device can replace manual work to collect information, so that the cost of camera positioning can be reduced.

Description

technical field [0001] The invention relates to the technical field of video surveillance, in particular to a camera positioning method and device. Background technique [0002] Video surveillance technology based on electronic map is widely used in traffic and public security systems. Through the monitoring area around the camera and the layout of the camera marked on the electronic map, the monitoring personnel can keep abreast of the actual situation of the monitoring location, and quickly formulate a response plan in case of an emergency. [0003] Usually, before using the electronic map to monitor, it is necessary to mark the corresponding point of the camera in the electronic map according to the actual installation position of the camera. The commonly used marking method is to manually collect the latitude and longitude information of the actual installation location of each camera, and then import the latitude and longitude information into the monitoring system, an...
