A system and method for capturing the trajectory of an object with multiple cameras

Abstract

The invention belongs to the technical field of remote video control, and particularly refers to a system and method for capturing the movement track of an object with multiple cameras. Assuming the shooting angle of view, the sum of the external shooting angles of all the lenses of the capturing cameras is greater than or equal to 360°; the shooting camera is installed on the second module, and the second module includes a reversible base, and the combination of the first module and the second module forms a pan-tilt; The control system of the capture camera synthesizes multiple groups of images captured by the camera into a panoramic image, and calculates the position of the moving object in the image; the shooting camera moves to the corresponding position under the drive of module 2 to realize real-time tracking of the moving object. The multi-camera design of the present invention can realize 360° intelligent tracking and detection without dead angle, and capture moving objects within the maximum angle range; the motion capture of the control module can be timely, stable and reliable.

Description

technical field [0001] The invention belongs to the technical field of remote video control, in particular to a system and method for capturing object motion tracks with multiple cameras. Background technique [0002] At present, tracking the movement trajectory of moving objects in the monitoring field through image analysis has been widely used, and most of them on the market are realized by a monitoring camera and a movable pan / tilt. The above method is directly applied to the automatic camera robot with horizontal 360° rotation for tracking, but this tracking method generally has the following defects: [0003] Defect 1: Automatic camera robots generally use one camera to work, and moving objects can only be tracked within the viewing angle range of the camera. However, the wide-angle lens of today’s cameras cannot achieve 360° panorama coverage, so there will inevitably be tracking errors. Even if the camera can rotate, when there are many tracking objects and they cha...

Problems solved by technology

[0003] Defect 1: Automatic camera robots generally use one camera to work, and moving objects can only be tracked within the viewing angle range of the camera. However, the wide-angle lens of today’s cameras cannot achieve 360° panorama coverage, so there will inevitably be tracking errors. Even if the camera can rotate, when there are many tracking objects and they change at the same time, it is difficult to capture their trajectory at the same time;

[0004] Defect 2: After the system performs image analysis and determines the target position, it needs to be transmitted to the control system in the gimbal. Since the gimbal is separated from the camera, the transmission between the two takes a long time. Fast, easy to cause incomplete tracking of object trajectory
