Embodiment Construction

[0058] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0059] The present invention designs a long-distance target tracking system in the air, such as figure 1 As shown, there are three base stations 1, 2, and 3. The base stations face the airspace of the target 4 along the light direction, and are distributed in a ring shape, and the distance between adjacent base stations is more than 20 meters. like figure 2 As shown, each base station includes a base 5 and an industrial computer 6 and a display screen 7 arranged in the base, and the top of the base 5 is provided with a wireless communication module 8 and a GPS timing positioning module 9 respectively connected to the industrial computer 6 , a tracking camera 10, a tracking camera 11 and a cloud platform 12. The tracking camera 10 and the follow-up camera 11 are fixed side by side on the platform 12, keeping the optical axes parallel to e...

Abstract

The invention discloses an aerial long-distance target following shot system and method. The system comprises at least three base stations; each base station comprises a base, and an industrial personal computer and a display screen arranged in the base; a wireless communication module, a GPS time service positioning module, a tracking camera, a following shot camera and a holder which are connected with the industrial personal computer are arranged at the top of the base. Target detection is started after the base station is initialized; after the target is tracked successfully, the focal lengths of the two cameras are adjusted at the same time, and the spatial position of the target is broadcasted to the system; all base stations share target information after entering a tracking state,three groups of target imaging information are utilized to determine the specific spatial position of a target, the position of the target at the next moment is predicted, the angle of a holder is adjusted in advance, and the base stations dynamically adjust the focal length of the following shot camera, so that the target always occupies a central area in a following shot picture. The method canquickly detect and stably track a long-distance target in the air, and clearly shoot the flight attitude of the target.

Description

technical field [0001] The invention belongs to the technical field of target tracking, and in particular relates to a system and method for tracking a long-distance target in the air. Background technique [0002] When using a camera to follow a long-distance target in the air, if the focal length of the camera is large, it is easy to lose the target; if the focal length of the camera is small, it is difficult to clearly capture the flight attitude of the target; Due to the shaking phenomenon, it is difficult to guarantee the shooting effect, so a device is needed to automatically realize the follow-up shooting of the aerial target. [0003] The existing automatic tracking device for aerial targets only uses a single camera, and it is very easy to lose the target due to the interference of background objects such as clouds and the sun; at the same time, it is difficult to quickly capture the emerging objects due to the small space area monitored by a single camera. The tar...
