Description

Technical Field

[0001] The utility model relates to the technical field of motion capture, in particular to an inertial motion capture device based on a VR base station. Background Art

[0002] Motion capture is the process of setting trackers at the key parts of a moving object. The trackers are set at the key parts of the moving object, and the Motioncapture system captures the position of the trackers, and then obtains the data of the three-dimensional space coordinates after computer processing. When the data is recognized by the computer, it can be applied in animation production, gait analysis, biomechanics, ergonomics and other fields. With the rapid development of computer software and hardware technology and the improvement of animation production requirements, motion capture has entered the practical stage in developed countries. Many manufacturers have successively launched a variety of commercial motion capture equipment. Motion capture often works in VR base stations, which can provide a lot of assistance for motion capture equipment, including signals, site layout, etc. In the process of motion capture, cameras are an indispensable part, and existing cameras are often fixed. In the process of motion capture, especially inertial motion capture, a large amount of site space is required. VR base stations can meet this requirement, but for the camera, the position of the camera needs to be adjusted continuously to prevent the inertial motion capture staff from leaving the camera or the camera from not keeping up with the inertial motion capture staff.
