Embodiment 1

[0038] Please refer to figure 1 , the present application discloses a method for obtaining relevant information of multi-person multi-rigid body TPose, the method includes steps S110-S150, which will be described separately below.

[0039] Step S110: The human body stands up and performs the TPose action, and obtains the position information set P{(P 1t , P 2t ,...P pt ) 1 , (P 1t , P 2t ,...P pt ) 2 ...(P 1t , P 2t ,...P pt ) N}, quaternion pose set Q{(Q 1t , Q 2t ,...Q pt ) 1 , (Q 1t , Q 2t ,...Q pt ) 2 ...(Q 1t , Q 2t ,...Q pt ) N}, the location information set of all marker points in the venue S{S 1t , S 2t ,...,S mt}), wherein, p is the body part label, N is the total number of the human body; m is the number of marking points;

[0040] In one embodiment, multiple human bodies first perform the TPose action at a certain distance, that is, the human body stands in a T-shape: the hands are spread horizontally, the legs are close together, the head ...

Embodiment 2

[0060] Please refer to figure 2 , the present application discloses a device 3 for obtaining relevant information of multi-person multi-rigid body TPose, including:

[0061] The acquisition unit 31 is used for the human body to stand and perform TPose actions, and acquire the position information set P{(P 1t , P 2t ,...P pt ) 1 , (P 1t , P 2t ,...P pt ) 2 ...(P1t,P 2 t,...P pt ) N}, quaternion pose set Q{(Q 1t , Q 2t ,...Q pt ) 1 , (Q 1t , Q 2t ,...Q pt ) 2 ...(Q 1t , Q 2t ,...Q pt ) N}, the location information set of all marker points in the venue S{S 1t , S 2t ,...,S mt}), wherein, p is the body part label, N is the total number of the human body; m is the number of marking points;

[0062] Judging unit 32, used to judge whether the rigid body information of the TPose is wrong according to the position information of the rigid body at time t and according to the first constraint condition; if the rigid body information is wrong, then obtain the cen...

Embodiment 3

[0065] Please refer to image 3 , the present application also discloses a device 4 for obtaining relevant information of multi-person multi-rigid body TPose, the device 4 may include a memory 41 and a processor 42, and include a method for obtaining multi-person information stored on the memory 41 and operable on the processor 42 Method program for multi-rigid body TPose related information. In addition, it should be noted that the method program for obtaining the relevant information of multi-person multi-rigid body TPose can be implemented by the processor 42 when executed by the processor 42. S150).

Abstract

The invention discloses a method for acquiring multi-person multi-rigid body TPose related information, which comprises the following steps of: standing a human body to perform TPose action, and acquiring a position information set, a quaternion posture set and a position information set of all mark points of a site of the rigid body at a t moment; judging whether the rigid body information of the TPose is wrong or not according to a first constraint condition; if yes, whether the position information set of all the mark points meets a second constraint condition on the XOZ plane or not is judged according to the central point of the head rigid body, and if yes, the position information of the corresponding mark points is recorded into a point set S'n; performing rigid body matching calculation by using the position information of the mark points in the S'n to obtain new rigid body position information; and if the new rigid body position information is judged to be correct, obtaining TPose related information of multiple persons and multiple rigid bodies. Through the method, the success rate of multi-person multi-rigid-body TPose under the complex environment condition can be greatly improved, the accuracy of solving rigid body position information and quaternion attitude information by a motion capture system is greatly improved, and then the motion capture precision of multi-person multi-rigid bodies is improved.

Description

technical field [0001] The present invention relates to the technical field of motion capture, and in particular to a method for obtaining information related to multi-person multi-rigid body TPose and its device and equipment. Background technique [0002] In the existing optical motion capture system, in the case of multi-rigid bodies and multi-person motion capture, problems such as rigid body flying strings are particularly prone to occur, that is, the rigid bodies on different people have wrong matches, which leads to errors in the calculation of human skeleton poses, etc. question. The motion capture calculation of the human body conforms to certain constraints or models, and the establishment of mutual constraints between the rigid bodies of various parts of the human body is helpful for the positioning and attitude estimation of the rigid bodies, which is conducive to the motion capture of the human body, and uses TPose related information to perform Target matching...
