TARGET TRACKING METHOD AND SYSTEM FOR INTELLIGENT TRACKING HIGH SPEED DOME CAMERA

摘要

Disclosed is a target tracking method for an intelligent tracking high speed dome, comprising: in the process of target tracking, when the position coordinates of a newly selected target in the acquired tracking image are received, matching the position coordinates of the newly selected target in the tracking image, using the target corresponding to the position coordinates of the newly selected target in the tracking image as a current target, and extracting the characteristics of the current target; tracking the current target according to the characteristics thereof, and updating in real time the position coordinates of the current target in the tracking image; converting the updated position coordinates of the current target into speed dome identifiable horizontal rotation value P, vertical rotation value T and magnification factor value Z; adjusting in real time the magnification factor of the speed dome according to the value Z, and controlling in real time the rotation of the speed dome according to the value P and the value Z. When a plurality of the targets appear in a specific scene, the present invention can lock a concerned target and track the target selectively, thus solving the previous problem of tracking an unconcerned target; furthermore, the method of the present invention can reselect and track a target by locking the target manually, thus solving the problem of losing the target.

1. A target tracking method for an intelligent tracking fast-speed dome, comprising:
matching a location coordinate of a newly-selected target in a collected tracking image when receiving the location coordinate of the newly-selected target in the tracking image in a process of tracking a target, setting a target corresponding to the location coordinate of the newly-selected target as a current target, extracting a characteristic of the current target; tracking the current target according to the characteristic of the current target, in real time updating the location coordinate of the current target in the tracking image; in real time transforming the updated location coordinate of the current target to a Pan (P) value, a Tilt (T) value and a Zoom (Z) value recognizable for a speed dome; and in real time adjusting a magnification according to the Z value, in real time controlling rotation of the speed dome according to the P value and the T value.
