Abstract: 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.

Abstract translation: 公开了一种智能跟踪高速球的目标跟踪方法，包括：在目标跟踪过程中，当接收到所获取的跟踪图像中新选择的目标的位置坐标时，将新选择的目标的位置坐标与 跟踪图像，使用与跟踪图像中的新选择的目标的位置坐标相对应的目标作为当前目标，并提取当前目标的特征; 根据其特征跟踪当前目标，并实时更新跟踪图像中当前目标的位置坐标; 将当前目标的更新位置坐标转换为高速球可识别的水平旋转值P，垂直旋转值T和放大系数值Z; 根据值Z实时调整圆顶的放大系数，并根据值P和值Z实时控制圆顶的旋转。当多个目标出现在特定场景中时， 本发明可以锁定相关目标并选择性地跟踪目标，从而解决跟踪不关心目标的先前问题; 此外，本发明的方法可以通过手动锁定目标来重新选择和跟踪目标，从而解决失去目标的问题。
