The embodiment of the invention provides an initialization method and device of hand shape identification, and a virtual reality terminal, and belongs to the technical field of human-computer interaction. The initialization method of the hand shape identification comprises the following steps: obtaining a static hand shape image; determining similarity independently between the obtained static hand shape image with a plurality of stored static hand shape image samples; and selecting a hand shape corresponding to the static hand shape image sample with the highest similarity as a tracking initialization state hand shape. By use of the initialization method and device of the hand shape identification, and the virtual reality terminal, on the basis of image segmentation and target detection, the static hand shape identification is combined to select the hand shape with the highest similarity, the initialization of target tracking is realized, target accuracy is improved, and tracking errors are reduced.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of human-computer interaction, and in particular, to a hand type recognition initialization method and device and a virtual reality terminal. Background technique [0002] Gesture recognition technology is an important technology of human-computer interaction. From simple and rough to complex and fine, it can be roughly divided into three levels: two-dimensional hand recognition, two-dimensional gesture recognition, and three-dimensional gesture recognition. [0003] Two-dimensional is just a plane space. The coordinate information composed of (X coordinate, Y coordinate) can be used to represent the coordinate position of an object in two-dimensional space, just like the position where a painting appears on a wall. On this basis, 3D adds the information of "depth" (Z coordinate), which is not included in 2D. [0004] Two-dimensional hand recognition, also known as static two-dimen...
