[0003] However, the continuous determination of the position of the hand, that is, hand tracking, is the most difficult and time-consuming part of gesture recognition.
Different from general object detection and tracking, the difficulty of hand tracking in gesture recognition is mainly reflected in three aspects: first, the high degree of deformation of the hand makes detection difficult; second, the movement of the hand in the camera's field of view Fast speed, difficult to track; third aspect, limited computing resources, difficult to run data

Aspects of the present invention relate to the technical field of gesture recognition, and in particular, to a hand tracking method and device. The hand tracking method includes: the step of obtaining video frames, obtaining continuous video frames; the judging step, judging whether a hand image is detected in the previous video frame according to whether there is a hand image in the previous video frame; single-scale local detection step, according to the hand image in the previous video frame, carry out hand detection in the local range of the current video frame, and mark the position of the hand image in the current video frame; the multi-scale global detection step, according to the previous video frame If there is no hand image, hand detection is performed on the entire range of the current video frame, and the position of the hand image in the current video frame is marked. By using two detection methods to detect and mark the hand position in the video, it is used to track the continuous movement trajectory of the hand image, which helps to improve the efficiency of hand tracking and reduce the difficulty of hand detection and real-time operation.
Description
technical field [0001] The present invention generally relates to the technical field of gesture recognition, and in particular to a hand tracking method and device. Background technique [0002] Gesture recognition is the pillar technology of touchless human-computer interaction without the help of mechanical devices such as touch screens. People can use simple gestures to control or interact with devices, allowing computers to understand human behavior, which is one of the important research directions in human-computer interaction. one. [0003] However, the continuous determination of hand position, that is, hand tracking, is the most difficult and time-consuming link in gesture recognition. Different from general object detection and tracking, the difficulty of hand tracking in gesture recognition is mainly reflected in three aspects: first, the high degree of deformation of the hand makes detection difficult; second, the movement of the hand in the camera's field of v...
