A three-dimensional scanning human motion capture device

Abstract

The invention relates to the technical field of action capturing, and discloses a three-dimensional scanning human body action capturing device. The three-dimensional scanning human body action capturing device comprises a base, wherein the upper end of the base is uniformly connected with a plurality of lifting cylinders at equal intervals by using the axis of the base as the center, and one endof each lifting cylinder is provided with an opening; the opening end of each lifting cylinder is arranged away from one end of the base; a lifting rod is inserted into each lifting cylinder; one end,away from the base, of each lifting rod penetrates through the opening of the corresponding lifting cylinder, extends out, and is fixedly connected with a bearing; the annular outside wall of each bearing is fixedly sheathed with a fixed plate; the upper end of each fixed plate is fixedly connected with a three-dimensional laser scanner; the scanning end of each three-dimensional laser scanner faces the axis of the base; the wall, near the bottom part, of each lifting rod is provided with a fixed groove; the bottom of each fixed groove is fixedly connected with a spring. The three-dimensionalscanning human body action capturing device can solve the problems of low precision in action capturing of the human body and easiness in interference by reflection in the capturing device.

Description

technical field [0001] The invention relates to the technical field of motion capture, in particular to a three-dimensional scanning human body motion capture device. Background technique [0002] There are various types of motion capture technologies, and the motion capture technologies mainly used in the market today mainly include the following: [0003] Mechanical motion capture, which relies on mechanical devices to track and measure motion trajectories. A typical system consists of multiple joints and rigid links. Angle sensors are installed in the rotatable joints to measure the change of the joint rotation angle. When the device moves, according to the angle change measured by the angle sensor and the length of the connecting rod, the position and motion trajectory of the end point of the rod in space can be obtained. Compared with optical motion capture, mechanical motion capture greatly hinders and restricts the performer's movements. [0004] Acoustic motion ca...
