Long-distance target tracking system and method based on long-short-focus camera group

Abstract

The present invention relates to the technical field of target tracking, in particular to a long-distance target tracking system and method based on a long-focus and short-focus camera group. The image is sent to the controller, the controller measures the target coordinates in the target image, the calculation module calculates the movement information of the telephoto camera according to the two coordinates, and the controller allows the telephoto camera to rotate to the target coordinates; the method includes rotating the S1 short-focus camera and Capture the target image and send it to the controller; S2 obtains the target coordinates from the target image, and the calculation module calculates the movement information of the telephoto camera according to the pre-stored initial coordinates and target coordinates; S3 makes the telephoto camera rotate and move the information to the target and capture the tracking image; After the S4 controller obtains the tracking image, it controls the second turntable to reset the telephoto camera. The invention can simultaneously ensure the breadth of the field of view of the shooting target and the clarity of the target.

Description

technical field [0001] The invention relates to the technical field of target tracking, in particular to a long-distance target tracking system and method based on a long and short focus camera group. Background technique [0002] With the development of network technology, the monitoring of environmental conditions is becoming more and more important as an important means to ensure public safety. The monitoring of environmental conditions generally uses cameras as the front-end medium to complete the acquisition of images in the environment and track the targets in the images through cameras. [0003] When tracking a target in an outdoor environment, a camera is usually used to track a distant target. If a telephoto camera is used to shoot a distant object, although the object captured by the telephoto camera is clear, the angle of view of the telephoto camera is very narrow, which is inconvenient. For large-scale search, there are all blind spots except the viewing angle; ...

[0003] When tracking a target in an outdoor environment, a camera is usually used to track a distant target. If a telephoto camera is used to shoot a distant object, although the object captured by the telephoto camera is clear, the angle of view of the telephoto camera is very narrow, which is inconvenient. If you use a wide-angle camera (short focus), although the wide-angle camera has a wide viewing angle and is suitable for wide-area search, it cannot take clear images for distant objects; if you use a variable magnification lens, The process of zooming in and out of the lens is slow, the timeliness is poor, and it is easy to lose the target during this process
