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

Abstract

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-short-focus camera group. The system comprises a support platform, a long-focus camera, a short-focus camera and a controller are arranged on the support platform, the short-focus camera captures a target image and sends the target image to the controller, the controller measures the target coordinates in the target image, the calculation module calculates the movement information of the long-focus camera according to the two coordinates, and the controller rotates the long-focus camera to the target coordinates. The method comprises the steps that: S1, the short-focus camera rotates and captures the target image and sends the target image to the controller; S2, the target coordinates are obtained from the target image, and the calculation module calculates the movement information of the long-focus camera according the pre-stored initial coordinates and the target coordinates; S3, the movement information of the long-focus camera is sent to the target to capture a tracking image; and S4, the controller obtains the tracking image to control a second turntable to reset the long-focus camera. The long-distance target tracking system and method based on a long-short-focus camera group can ensure the breadth of the field of view of theshooting target and the sharpness 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-focus and short-focus camera group. Background technique [0002] With the development of network technology, monitoring of environmental conditions is becoming more and more important as an important means of ensuring public safety. The monitoring of environmental conditions is generally completed using cameras as the front-end media, through which images in the environment are obtained and targets in the images are tracked. [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...

[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
