The invention provides a gesture recognition device for virtual reality equipment, comprising: a gesture acquisition module used for obtaining a depth image of a user hand; a model building module used for building a 3D hand model and a state feature model in a virtual space according to the obtained depth image of the hand; a matching module used for carrying out state matching on the 3D hand model and the hand image according to the state features of the hand image to obtain the state information of the 3D hand model; a tracking module used for tracking the 3D hand model to obtain the statechange of the 3D hand model, wherein the state change includes movement and deformation; and a gesture recognition module used for recognizing a gesture expressed by the 3D hand model according to thestate change of the 3D hand model and outputting a corresponding recognition result. The problem that the traditional method has a poor recognition effect in gesture tracking can be prevented. The gesture recognition device has a simple structure, and is suitable for most virtual reality equipment.
Description
technical field [0001] The invention relates to the technical field of virtual reality, in particular to a gesture recognition device for virtual reality equipment. Background technique [0002] At present, most of the gesture analysis systems that are relatively mature in the market require sensors or optical markers to be worn on the human hand. Sensor-based systems acquire motion data by attaching sensors to the tracked object. Such systems can guarantee a certain degree of accuracy, but are usually expensive, require complex calibration steps, and interfere with the motion of the tracked object. The optical marker-based system places optical markers on the joints of the human hand, and then tracks these markers through the camera. However, the occlusion of the human hand during the movement will cause some markers to be invisible, so this type of system requires manual analysis of the captured data. Do postprocessing. [0003] In comparison, the markerless gesture trac...
