Embodiment Construction

[0039] The technical solutions of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments, and the following embodiments do not constitute a limitation of the present invention.

[0040] A method for target detection and tracking in this embodiment is implemented by a linked camera group composed of two positioning cameras and one close-up camera, such as figure 1 shown, including:

[0041] 1) According to the target to be tracked, set up two positioning cameras on a horizontal plane of a certain height, so that the fields of view of the two positioning cameras intersect, and the intersecting part covers the monitoring area to be monitored, and also sets the field of view to cover the monitoring area. close-up camera.

[0042] In this embodiment, the two positioning cameras are arranged on a horizontal plane at the same height. Preferably, the positioning cameras are placed horizontally, and the center of the...

Abstract

The invention discloses a method and a system for detecting and tracking a target. Two positioning cameras are arranged on a horizontal plane at a certain height according to the target to be tracked, so that vision fields of the two positioning cameras are intersected; a monitored area is covered by an intersected part; simultaneously, a close-up camera, the vision field of which covers the monitored area, is also arranged; calibration equipment establishes a mapping relationship of a target position and latitude and longitude coordinates of the close-up camera by calibrating the target position and the latitude and longitude coordinates of the close-up camera according to a set target detection area; and thus, the latitude and longitude coordinates of the close-up camera corresponding to the target position are obtained according to the established mapping relationship after the positioning cameras detect the target and obtain the target position, so that tracking is performed. By means of the method and the system disclosed by the invention, ground projection and complex background interference can be effectively avoided; and the system cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of video surveillance, and in particular relates to a method and system for target detection and tracking. Background technique [0002] Target detection and tracking has always been an important topic in the field of video surveillance technology. By continuously tracking and shooting moving targets in the monitoring scene, it is beneficial to obtain stable and clear video images of moving targets and provide strong security for security. Technical Support. At present, it is more and more used in large exhibition halls, conference halls and other important places, which greatly saves manpower and material resources in security, and can also fill the loopholes that fixed-camera cameras cannot track and shoot moving targets. [0003] The existing video surveillance solutions for detecting and tracking targets usually use the linkage between the bolt and the dome, and the bolt and the dome monitor the same mo...
