Problems solved by technology

Target tracking is widely used in video surveillance. It is the basis of later behavior analysis, target recognition and classification. Accurate and stable real-time tracking of interested targets is a challenging topic in the field of intelligent video surveillance, especially in complex In the scene, stable and real-time tracking of multiple targets, there are complex situations such as occlusion and mutual fusion, making it more challenging

Embodiment 1

[0025] Embodiment 1, a kind of expressway moving target tracking method, with reference to appended figure 1 .

[0026] The present invention will at first hang the camera (being tracking device) with tracking function on the crossbar above the expressway, if monitor one-way passage, then hang in the center of one-way passage, parallel to expressway, mark the one-way passage Area range, and mark the driving direction of the vehicle; if the two-way passage is monitored, hang in the center of the two-way passage, parallel to the expressway, and mark the area range of the two-way passage and the driving direction of the vehicle respectively.

[0027] After the marking step is completed, the moving object in the current frame is obtained by the moving object detection method based on the mixed Gaussian background modeling.

[0028] Obtain the target queue being tracked in the previous frame, assuming that the interval between two adjacent frames is unit 1, the calculated speed of...

Embodiment 2

[0046] Embodiment 2, a kind of freeway moving target tracking system, with reference to the attached figure 2 .

[0047] A highway moving target tracking system, including a rule setting unit 1 for setting an area of ​​interest in an image and a vehicle driving direction, and an image acquisition unit 2 for collecting monitoring images, for obtaining a moving target in a current frame and adjusting The moving target detection unit 3 for tracking target position, size, normalized histogram and other information matched by the current frame search is used for processing the tracking queue processing unit 4 of the target queue being tracked, and for processing the lost tracking target queue. Lost tracking queue processing unit 5, a queue to be tracked processing unit 6 for processing the target queue to be tracked and a new target processing unit 7 for processing newly occurring moving objects and initializing; the rule setting unit 1 and the image Acquisition unit 2 is connect...

Abstract

The invention provides a method for tracking moving objects on a highway. The method comprises the following steps: labeling an interested area and a vehicle driving direction; obtaining a moving object in a current frame; and obtaining an object queue, which is being tracked by the previous frame, obtaining an object queue to be tracked by the previous frame, obtaining an object queue, tracking of which is lost by the previous frame, putting remained moving objects in a queue to be tracked; and initializing for next-frame tracking. According to the invention, according to the vehicle driving characteristics on the highway, only one-way driving direction of a vehicle is arranged in one interested area; the forward driving direction of the vehicle is artificially arranged in combination with the relationship of the erection angle of a camera and a lane; therefore, the characteristic change tendency in the vehicle driving process can be effectively obtained; the number of object searching areas and templates required for searching can be reduced in an object searching and matching stage; and thus, the tracking accuracy and efficiency can be increased to a much greater extent.

Description

technical field [0001] The invention relates to an intelligent traffic monitoring technology, in particular to a method and system for tracking a moving object in an expressway intelligent traffic monitoring system. Background technique [0002] With the development of the economy and the advancement of transportation technology, the demand for video surveillance has also increased rapidly. Manual surveillance has been far from meeting the needs of traffic monitoring, and the demand for intelligent video surveillance technology has become very urgent. [0003] In recent years, the rapid development of computer hardware performance has enabled embedded devices to have faster processing speeds and greater storage capabilities. They are the front-end eyes and brains of embedded intelligent video surveillance systems. The transmission capability and analysis capability of the system play a key role. Target tracking is widely used in video surveillance. It is the basis of later ...
