Embodiment Construction

[0028] In order to make the above and other features and advantages of the present invention clearer, the present invention will be further described below in conjunction with the accompanying drawings. It should be understood that the specific embodiments given herein are for the purpose of explaining to those skilled in the art, and are only exemplary rather than restrictive.

[0029] According to the monitoring needs of conventional security, management, etc., the management party needs to install and set up the camera equipment by itself, and transmit the collected video to the central monitoring room for archiving and viewing. High-definition camera equipment should be deployed in core areas, important entrances and exits, and traffic distribution centers to identify pedestrians, obtain fine features, and avoid omissions.

[0030] If there is already a corresponding reference electronic map in the design and installation stage, it can be imported into the system as the ba...

Abstract

The invention provides a positioning method and a positioning system. The positioning method comprises the following steps: searching whether a position of at least one camera device for acquiring a current video exists in an electronic map; when it is determined that the position of the at least one camera device does not exist, the current moving track of the at least one moving object is determined according to the current video collected by the at least one camera device; matching the current moving track of each moving object in the at least one moving object with a historical moving track determined by a stored historical video; after it is determined that the current moving track of at least one moving object is at least partially matched with the historical moving track, whether the matched moving track of the moving object is connected to the electronic map or not is analyzed; and when the connection cannot be realized, determining the relationship between the camera equipmentfor acquiring the moving track of the matched moving object and the close camera equipment according to the moving track of the matched moving object, and correcting the position of the close cameraequipment in the electronic map.

Description

technical field [0001] The invention relates to the field of camera equipment, in particular to a positioning method and a positioning system. Background technique [0002] The relative position, coverage range, overlapping range and blind spot of each camera device in the existing determined area mostly rely on the roughly determined position information when the camera device is installed to determine the position of the camera device on the electronic map. However, along with the daily management of the area, camera equipment is usually added, repaired, replaced, etc., so that the position of the originally installed camera equipment will be changed. However, for the camera device whose position changes, it is necessary to rely on on-site measurement to obtain the position of the camera device, so that the electronic map can be updated. The method of obtaining the position of the camera device through on-site measurement will result in low efficiency and untimely updatin...
