Embodiment 1

[0037] Please refer to figure 1 , the present application discloses a method for acquiring multi-person multi-rigid body TPose information, the method includes steps S110-S150, which will be described separately below.

[0038] Step S110, the human body stands up and performs 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 lt , Q 2t ,...Q pt ) N}, the location information set of all marker points in the venue S{S 1t , S 2t ,...,S mt}) and other information, wherein, p is the label of the body part, N is the total number of the body; m is the number of marking points;

[0039] 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...

Embodiment 2

[0061] Please refer to figure 2 , the present application discloses a device 3 for acquiring multi-person multi-rigid body TPose information, including:

[0062] 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 ...(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;

[0063]The judging unit 32 is used to obtain the distance between any two rigid bodies, and judge whether the rigid body information of TPose is wrong according to the first constraint condition; obtain the approximate plane WOL composed of both hands and the waist rigid body, ...

Embodiment 3

[0066] Please refer to image 3 , the present application also discloses a device 4 for acquiring multi-person multi-rigid body TPose information, the device 4 may include a memory 41 and a processor 42, and includes a multi-person and multi-body multi-body multi-body information stored in the memory 41 and operable on the processor 42. Method procedure for rigid body TPose information. In addition, it should be noted that the method program for obtaining multi-person multi-rigid body TPose information here can implement the steps of the method for obtaining multi-person multi-rigid body TPose information in Embodiment 1 (ie steps S110 and S150 ) when executed by the processor 42 .

[0067] It should be noted that, in this embodiment, the method program for obtaining multi-person and multi-rigid body TPose information stored on the memory 41 may include some functional modules, such as the obtaining unit 31, the judging unit 32 and the computing unit requested for protection i...

Abstract

The invention discloses a method for obtaining multi-person multi-rigid-body TPose information, and the method comprises the steps: enabling a human body to stand for TPose motion, and obtaining a position information set of rigid bodies of the head, the waist, the two hands and the two feet of each person at a t moment; according to a first constraint condition, a second constraint condition and a third constraint condition, judging whether the rigid body information of the TPose is wrong or not; and if the rigid body information is judged to be wrong, entering a step of finding rigid body calculation, otherwise, acquiring TPose related information of multiple persons and multiple rigid bodies according to a correct rigid body position information set. 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 invention relates to the technical field of motion capture, in particular to a method for acquiring multi-person multi-rigid body TPose information 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 information for target The matching and modeling of the human body ca...
