Mark point setting device for motion capture and repeated positioning system and method

Abstract

The invention relates to a mark point setting device for motion capture. The mark point setting device comprises a capture point setting base plane and a mark recognition device, the capture point setting base plane can be tightly attached to an object to be detected, and one surface of the capturing point setting base surface is an adhesive surface used for being adhered to the object to be detected; a position mark is arranged on the other surface of the capturing point setting base surface, and the position mark is a scale line grid formed by crisscrossed scale lines on the capturing point setting base surface; the invention further relates to a repeated positioning system and an execution method thereof. The repeated positioning system comprises a mark point setting device, a positioning recording device, a positioning identification device and a to-be-detected placement area. The to-be-measured placement area is used for fixing the position of a to-be-measured object, the positioning identification device is used for marking the position information of the mark point setting device on the positioning recording device, and the to-be-measured placement area is located between the mark point setting device and the positioning recording device; the invention has the advantages that free setting of the mark points can be supported, the relative positions of the mark points can be recognized, and repeated positioning is facilitated.

Description

technical field [0001] The invention relates to the technical field of motion capture, in particular to a marker point setting device, a repeat positioning system and a method for motion capture. Background technique [0002] The motion capture system is an important means for kinematics analysis, which records the human body surface skin mark recognition device through the motion capture equipment to obtain the three-dimensional motion state. Through the mark recognition device of the body surface skin, the movement trajectory of key points on the body surface in three-dimensional space is recorded, so as to analyze the human body movement pattern. During the use of the motion capture system, it is necessary to fix the marker recognition device on the human body surface, and the fixation of the marker recognition device for key points on the body surface is the key point of the motion capture technology. At present, the fixing methods of body surface mark recognition devic...

This patent sets the marking points on the vest, and then realizes the ups and downs of the chest through the elasticity of the vest; but first, it lacks positioning capabilities. Although the marking points are fixed on the vest, it cannot ensure that when it is worn again, the position remains the same as last time. Consistent, and not universal for people of different body types; second, the position of the marker point cannot be set freely, and cannot cope with the motion capture of a specific position required for kinematics analysis, such as different people wearing a marker point Behind the vest, the position of the marking point is different relative to the position of the internal organs and bones of the individual, and the marking point does not have the ability to adjust
