Motion capturing system

Abstract

The invention discloses a motion capturing system which is used for collecting motions of an operator to form real-time images. The motion capturing system comprises a dynamic capturing device used for correspondingly collecting motion data for motions of the operator who wears the dynamic capturing device. The dynamic capturing device comprises a plurality of collecting units, a sending unit, a processing unit, a receiving unit and a control unit, wherein the collecting units are arranged at a plurality of preset positions of the dynamic capturing device respectively, each collecting unit corresponds to one unique position identification, the collecting units are used for collecting the motion data of the corresponding preset positions in real time, the sending unit is used for outputting the motion data, the processing unit is used for receiving the motion data sent by the collecting units and sending the motion data to the sending unit, the receiving unit is connected with the sending unit and used for receiving the motion data, and the control unit is used for establishing 3D postures of a human body by means of a preset human body motion model according to the motion data and generating the real-time images according to the 3D postures.

Description

technical field [0001] The invention relates to the field of gesture detection, in particular to a motion capture system. Background technique [0002] Existing motion capture is mainly used in aerospace, aviation and 3D film production, etc., such as: the navigation system of unmanned aerial vehicles has just adopted motion capture technology. In the existing 3D movie production process, photoelectric sensors are generally used to collect the movement trajectory of the person to be tested, and the reflective points of the photoelectric sensor are captured by multiple cameras with different angles, which has high requirements on the environment. Impact, high cost, currently supported, but due to the high hardware requirements for image calculation, and the disadvantage of large delay, the narrow application range is not easy to popularize. The number of traditional motion capture sensors is large and scattered. When using it, the motion capture sensors need to be attached t...

Problems solved by technology

In the existing 3D movie production process, photoelectric sensors are generally used to collect the movement trajectory of the person to be tested, and the reflective points of the photoelectric sensor are captured by multiple cameras with different angles, which has high requirements on the environment. Impact, high cost, currently supported, but due to the high hardware requirements for image calculation, and the disadvantage of large delay, the narrow application range is not easy to popularize

The number of traditional motion capture sensors is large and scattered. When using it, the motion capture sensors need to be attached to the person to be tested one by one, and the corresponding position of each motion capture sensor is fixed. If the position of the motion capture sensor is wrongly pasted, it will directly affect the accuracy of the acquisition Data, the operation is cumbersome, and the current motion capture sensors generally use three-axis or six-axis data collection, with low accuracy
