Problems solved by technology

[0003] The traditional target tracking method based on optical flow needs to calculate the optical flow information through two frames of images first, which consumes a lot of computing power in the calculation process, which is a big challenge to the real-time performance of the algorithm.
On the other hand, when the target is in a fast-moving state, traditional tracking methods are prone to tracking loss

Embodiment Construction

[0026] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0027] In recent years, Dynamic Vision Sensor (DVS) has received more and more attention and applications in the field of computer vision. DVS is a biomimetic visual sensor that mimics the human retina based on spike-triggered neurons. The sensor has a pixel unit array composed of multiple pixel units, and each pixel unit will respond and record the area where the light intensity changes rapidly only when it senses a change in ligh...

Abstract

The invention discloses a target tracking method suitable for execution in a computing device, which includes that steps of generating an optical flow image by using a series of event data from a dynamic vision sensor, the event being triggered by a relative motion of the target object and the dynamic vision sensor; Determining a motion speed and a motion direction of at least one target object ina current image frame based on an optical flow image; Predicting the position of the corresponding target object in the next image frame according to the motion direction and the motion speed; And when the predicted position is within the field of view, taking the corresponding target object as the target to be tracked. The invention also discloses a corresponding computing device.

Description

technical field [0001] The present invention relates to the technical field of target tracking, in particular to a target tracking method and computing equipment. Background technique [0002] Target tracking has a wide range of applications in both military and civilian fields, such as air surveillance, satellite and spacecraft tracking, and intelligent video surveillance. Accurate tracking of targets is conducive to accurately understanding the position of the opponent's targets, and is the core technology of high-tech weapon systems and GPS systems. At the same time, with the application of assisted driving systems, how to reasonably use target tracking processing technology to protect the safety of pedestrians and vehicles is also a current hot research direction. [0003] The traditional target tracking method based on optical flow needs to calculate the optical flow information through two frames of images first, which consumes a lot of computing power in the calculat...
