Abstract

The invention discloses a dynamic gesture recognition method and system, a readable storage medium and computer equipment. The method comprises the steps: carrying out the hand target detection of a target image through a trained hand detection deep learning model, so as to obtain the graphic information of a minimum enclosing rectangle of a hand region; according to the graphic information of the minimum bounding rectangles corresponding to the second moment and the first moment, calculating a center distance and a slope between the minimum bounding rectangles corresponding to the two moments; segmenting a hand skin region of the target image through a skin detection algorithm, and calculating average depth values of the hand skin region corresponding to the second moment and the first moment in combination with the depth map; and judging the gesture movement direction and the movement amount in the corresponding direction according to the center distance, the slope and the average depth values of the hand skin regions corresponding to the two moments. The problems that only the moving direction on the two-dimensional plane can be judged, the calculation process is complex, and the gesture recognition real-time performance is low in the prior art can be solved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a dynamic gesture recognition method, device, readable storage medium and computer equipment. Background technique [0002] Gesture recognition is an important means of human-computer interaction. In VR (Virtual Reality, virtual reality technology) human-computer interaction, users can adjust the volume or control other virtual mobile buttons through virtual gesture recognition. [0003] In the prior art, the image is mainly gridded, and the skin detection algorithm is used to mark whether there is a hand in each grid, the binarized image, and then the direction of the hand movement is obtained through the logical operation of the binary image. This method can only Determine the direction of movement on a two-dimensional plane. In addition, there is also gesture recognition based on the Tower algorithm. The calculation process is very complicated and the amount of calculation i...
