Problems solved by technology

This process is very time-consuming, because it is time-consuming to find cameras in 8 directions around each camera. This generally requires people who are very familiar with the local geographic location to operate, and other people cannot operate it. Therefore, establish a topology for the camera. Very difficult relationship
Moreover, for a large number of metropolitan area cameras, the entry personnel are prone to fatigue, which greatly increases the probability of making mistakes
Another big problem is that when the traditional method builds topology, it is difficult to ensure the interrelationship between cameras

Embodiment Construction

[0023] The present invention provides a method for quickly constructing topological relationships of mass video cameras in metropolitan areas, comprising the following steps:

[0024] Step 1: When actually installing and establishing the camera, create an EXCEL sheet corresponding to the camera information, which records the name of the camera, the longitude and latitude of the geographic location, the corresponding IP address of the camera and its channel number;

[0025] Step 2: Write an ID number for each camera in the EXCEL table, and the ID number of each camera corresponds to the IP address, channel number, longitude, latitude, and name of the camera;

[0026] Step 3: Create a new topological relational database table and a camera resource information table, wherein the topological relational database table contains 9 fields, which are respectively the camera ID number and the cameras located in the northwest, north, northeast, east, southeast, south, and southwest of the...

Abstract

The invention relates to a method for quickly constructing the topological relation of a metro mass video camera. In combination with database knowledge and ArcGis geographic information system related knowledge, an EXCEL information sheet of the camera is automatically read and data are automatically accessed in a database based on a computer, the position of the camera is visually shown on a GIS map, and in addition with a manually auxiliary mode, the topological relation of the metro mass video camera can be quickly and accurately constructed.

Description

technical field [0001] The invention relates to the related field of video monitoring, and relates to a method for quickly constructing topological relationships of massive video cameras in the metropolitan area by utilizing powerful computing capabilities of computers and combining database operations with ArcGIS geographic information resources and the like. Background technique [0002] With the continuous maturity of computer vision, pattern recognition and other technologies, video image resources are more and more widely used in various fields of society. Especially in the smart city construction that has emerged in recent years, a large number of cameras have been installed in the city. Since a single camera is an independent unit, in order to make full use of video resources, it is necessary to establish a topological relationship between different cameras, but in the face of such a large number of camera resources, establishing a topological relationship is very cum...
