Abstract

A method, device and system for object tracking in a disparity map, the method comprising: extracting a previous convex hull in an object template of a previous frame, the previous convex hull at least including a previous torso convex hull and a previous limb convex hull; In the current frame, the part matching the previous trunk convex hull is detected as the current trunk part; each current limb convex hull is extracted in the area around the current trunk part; according to the respective gradients of the current limb convex hull and the previous limb convex hull Main direction, for a previous limb convex hull, rotate the gradient main direction of each current limb convex hull to be consistent with the gradient main direction of the previous limb convex hull; find the rotated current limb that matches the previous limb convex hull Convex hull; according to the matching result, the object template in the current frame is determined to realize object tracking.

Description

technical field [0001] The technology relates to the fields of stereo vision, computer detection and tracking, and more particularly, relates to a method, device and system for object tracking in a disparity map. Background technique [0002] The application fields are related to assisted driving, automatic identification and tracking, driving warning and other fields. In stereo vision projects for intelligent driving, it is important to track objects such as pedestrians or animals, especially in urban scenes. However, tracking a moving object is difficult due to changes in the pose of the object and changes in the background as well as the distance of the object. [0003] Therefore, a technique for object tracking in disparity maps is needed. Contents of the invention [0004] According to one aspect of the present invention, there is provided a method for object tracking in a disparity map, comprising: extracting the previous convex hull in the object template of the p...
