Problems solved by technology

However, when the camera tracks the target, it can only track the target within the range it can capture. When the target is blocked or the target is outside the camera's field of view, the camera cannot capture the target, so it is difficult for the camera to capture the target. Continue to track the target, thus reducing the efficiency of target tracking

example 1

[0293] Example 1, the preset tracking queue may include candidate tracking target A, candidate tracking target B, and candidate tracking target C, wherein candidate tracking target A is a candidate tracking target specified by the user, then when the radar needs to determine the target to be tracked, The candidate tracking target A is directly determined as the target to be tracked.

example 2

[0294] Example 2, the preset tracking queue may include candidate tracking target A, candidate tracking target B, and candidate tracking target C, wherein candidate tracking target B is a candidate tracking target whose tracking is interrupted, that is, the radar has detected candidate tracking target B before Unexpected interruption in the process of tracing. Then, when the radar determines that there is no specified candidate tracking target among candidate tracking target A, candidate tracking target B and candidate tracking target C, candidate tracking target B may be determined as the target to be tracked.

example 3

[0295] Example 3, the preset tracking queue may include a candidate tracking target A, a candidate tracking target B, and a candidate tracking target C, wherein the candidate tracking target C is a candidate tracking target currently being tracked by the radar. Then, when the radar determines that there is no specified candidate tracking target among candidate tracking target A, candidate tracking target B, and candidate tracking target C, and there is no candidate tracking target whose tracking is interrupted, it can continue to judge that candidate tracking target C has been continuously tracked Whether the duration of the tracking target C is greater than the preset duration threshold of 10 seconds, if the candidate tracking target C has been tracked for 5 seconds, the candidate tracking target C can be determined as the target to be tracked.

[0296] Example 4, the preset tracking queue may include candidate tracking target A, candidate tracking target B, and candidate trac...

Abstract

The embodiment of the invention provides a target tracking method and device, and the method comprises the steps: determining a to-be-tracked target; tracking the to-be-tracked target, and obtaining the position of the to-be-tracked target as a target position according to a preset time interval; after the target position is obtained each time, sending a control instruction carrying the target position to the camera, so that the camera receiving the control instruction responds to the control instruction. According to the technical scheme provided by the embodiment of the invention, the radaris used for tracking the to-be-tracked target, and the camera responds to the control instruction of the radar, so that the target tracking accuracy is improved, and the target tracking efficiency isalso improved.

Description

technical field [0001] The invention relates to the technical field of intelligent monitoring, in particular to a target tracking method and device. Background technique [0002] Radar can detect targets in the covered area through radio electromagnetic waves and determine the spatial position of the target. The camera can shoot the target, and then obtain the detailed information of the captured target, and, as the target moves, the camera can follow the rotation, so that the tracking and shooting of the moving target can be realized. [0003] Therefore, based on the respective functions of the radar and the camera, the radar and the camera have been connected by communication to form a linkage system. The radar is used to obtain the position information of the target and send the obtained position information to the camera. The position of the target, and turn to this position, capture the target, and continue to track the target. [0004] In the current linkage system o...
