Abstract

The invention discloses a real-time reconstruction method and device for a hand and object interaction process, and the method comprises the following steps: carrying out the data segmentation of to-be-processed depth image data, obtaining a hand and object segmentation result, and obtaining gesture posture prediction data, and the hand and object segmentation result comprising object data and hand data; dividing the prediction data and the hand and object into constraint terms to optimize the unified energy function, so as to obtain a hand motion sequence and an object non-rigid motion sequence; and fusing the object data into the object model to obtain an object static model, and obtaining a real-time reconstruction result of the hand and object interaction process according to the handmotion sequence, the object non-rigid motion sequence and the object static model. The method can effectively solve the real-time reconstruction problem of hand and object interactive motion, and canobtain hand motion, object motion and object geometric models in real time.

Description

technical field [0001] The invention relates to the technical fields of computer vision and computer graphics, in particular to a real-time reconstruction method and device for the interaction process between a hand and an object. Background technique [0002] The interactive motion of hands and objects is a very common activity in people's daily life, and the reconstruction of the interactive motion between hands and objects is a problem that must be solved for the full 3D reconstruction of human activities. Moreover, the interaction between hands and objects not only contains human intentions, but also reflects a person's health status. [0003] Therefore, it is of great scientific significance to reconstruct the interaction process between the opponent and the object. Gesture tracking and object motion and model reconstruction are two problems directly related to hand-object interaction motion reconstruction, and they are also two important and basic problems in the fiel...
