Embodiment Construction

[0034] The embodiment of the present invention provides a method and system for video tracking analysis combined with geographic information. Through initialization, the target object is determined and its feature information is extracted, and the initial position and time starting point information of the target object and the next position of the target object are obtained. and the required time information, and then match the video within the specified time period of the next location, then process the location information according to the matching result, and finally store and output the path information of the target object, effectively utilizing the distance between the cameras in the monitoring system The correlation of the camera network space and time is fused, combined with the geographical location information of the camera, and the target driving path is automatically analyzed.

[0035] In order to make the object, technical solution and advantages of the present in...

Abstract

The invention provides a video tracking analysis method and a system combined with geographic information. According to the invention, an object is confirmed and the characteristic information thereof is extracted through initialization, so the information of the object, such as, initial position, starting time, the next position and the required time spent in reaching the next position, is obtained; the video in the specific time section of the next position is subjected to matching; the position information is subjected to processing according to the matching result; and the path information of the object is stored and output. According to the invention, the camera relevance of a monitoring system is effectively utilized, the network space of the cameras and the time relevance is combined, and the object driving path can be automatically analyzed based on the geographic information obtained through the cameras.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a video tracking analysis method and system combined with geographical information. Background technique [0002] In recent years, with the rapid development of the national economy, more and more vehicles are driving on expressways and urban expressways in my country, and the speed is getting faster and faster, and the cases related to vehicle traffic are also on the rise. Video monitoring has been widely used in traffic management methods, but the actual monitoring tasks still need more manual completion. Especially in the case of tracking the escaping vehicles, the number of surveillance videos is large and the background is complicated, which often requires a lot of manpower and material resources, takes a long time, and there are certain omissions. [0003] As an important part of smart security and smart transportation in the application of the Internet of Things for ...
