Embodiment Construction

[0061] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0062] In some embodiments, the object tracking method of the present disclosure can be applied to different scenarios. For example, it can be applied to automatic driving scenarios to track targets in images collected by image acquisition devices on vehicles. For another example, it can be applied to a traffic monitoring scene to track a target in an image captured by an image acquis...

Abstract

The invention relates to a target tracking method and device and a storage medium. The method comprises the following steps: acquiring an image acquisition sequence; object detection is carried out on a first image in the image acquisition sequence, a 3D detection frame of an object on the first image in the target three-dimensional space and a 2D detection frame of the object on the first image are obtained, and the first image is any image except the first image in the image acquisition sequence; predicting a 3D prediction frame of the target object in the target three-dimensional space and a 2D prediction frame of the target object on the first image according to a tracking result of tracking the target object for a second image, the second image being a previous image of the first image in the image acquisition sequence; and according to the 3D detection frame, the 2D detection frame, the 3D prediction frame and the 2D prediction frame, determining a tracking result of tracking the target object for the first image. Through the target tracking method disclosed by the invention, the tracking accuracy of the target object can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of computer vision, and in particular, to a target tracking method, device and storage medium. Background technique [0002] Target tracking is to find the target in the image sequence by given an image sequence, identify the same target in different frames, and assign IDs to the same target in different frames. In the related art, target tracking is usually performed based on 2D information. However, it is difficult to perform accurate motion estimation of the target only by using 2D information, resulting in the occurrence of erroneous tracking. SUMMARY OF THE INVENTION [0003] In order to overcome the problems existing in the related art, the present disclosure provides a target tracking method, device and storage medium. [0004] According to a first aspect of the embodiments of the present disclosure, there is provided a target tracking method, including: [0005] acquiring an image acquis...
