Abstract

The invention belongs to the field of visual tracking and discloses a visual tracking system and method. The system comprises an image acquisition device, a light path conversion device and a light path adjustment device. The image acquisition device comprises a first camera and a second camera which are fixed in relative positions, and the first camera is used for acquiring an image and performing visual tracking to predict the position of a to-be-tracked target. The light path conversion device is arranged between the to-be-tracked target and the second camera and is used for clearly imagingthe to-be-tracked target on the second camera. The light path adjusting device adjusts the light path of the light path conversion device in real time according to the position of the to-be-tracked target, so that the target is always located at the imaging center of the second camera. The visual tracking method comprises the following steps: obtaining each frame of image by using a first cameraand carrying out visual tracking to predict the position of a target in each frame of image; and adjusting a light path in real time according to the position of the target to clearly image the targetat the center of the second camera. The method has the advantages of high speed, high robustness, good adaptability and the like.

Description

technical field [0001] The invention belongs to the field of visual tracking, and more particularly relates to a visual tracking system and method. Background technique [0002] With the rapid development of computer vision and machine vision technology, artificial intelligence has changed from the simple pursuit of accuracy in the past to the current situation of equal emphasis on accuracy, robustness and real-time performance. Only in this way can the rapid implementation of technology be accelerated. As one of the popular research directions of computer vision, visual tracking can not only be used as a part of complex technologies such as behavior recognition and video target detection, but also can be widely used in daily life and production as a separate technology, such as industrial robots, intelligent Security and unmanned driving and other fields. [0003] Visual tracking refers to the position of the target in the first frame and a video sequence, and it is requir...
