Abstract

The present invention relates to a static pose fixture (10) used for measuring a subject (42) that is the object of a motion capture system. The static pose fixture (10) provides a means for holding the subject (52) in a static position by using various struts in order to automate the sizing of a computer generated model or to position and orient markers with respect to the model.

Claims

1. A system for measuring a person who is a subject of a motion capture model, the system comprising:

a static pose fixture;

a plurality of markers positioned on the person;

means for recording the position and orientation of each of the plurality of markers positioned on the person;

means for measuring the subject to generate a plurality of measurements;

means for converting the measurements into a localized coordinate system; and

means for generating a computer model of the subject based on the measurements.

2. The system according to claim 1 wherein the static pose fixture comprises:

a base having a substantially flat surface;

a pair of foot alignment struts located on the upper rear surface of the base wherein the distance between a first foot alignment strut and a second foot alignment strut is at least 10.0 inches;

a pair of vertical struts located on the upper rear surface of the base wherein a first vertical strut is located on an outer exterior portion of the first foot alignment strut and a second vertical strut is located on an outer exterior portion of the second foot alignment strut; and

a pair of grips attached to the pair of vertical struts and located at least 15 inches above the base.

3. A method for measuring the size of a motion capture subject, the method comprising:

placing the motion capture subject in a marker interface suit having a plurality of markers;

optimizing the position of each of the plurality of markers on the motion capture subject during a golf club swing by the motion capture subject;

constraining the motion capture subject in a static position and orientation for measurement of the geometry and location of each of the plurality of markers; and

capturing a swing motion of the motion capture subject using a motion capture system.

4. A method of measuring a subject which is an object of a motion capture model, the method comprising:

attaching at least one body plate to the subject;

optimizing a location of the at least one body plate;

positioning the subject in a static pose;

measuring at least two joint segment lengths of the subject;

converting the measurements of the two joint segment lengths into a localized coordinate system; and

generating a computer model of the subject based on the measurements of the two joint segment lengths.

5. The method according to claim 4 wherein the positioning the subject in a static pose comprises positioning the subject within a static pose fixture.

6. The method according to claim 5 wherein the static pose fixture comprises:

a base having a substantially flat surface;

a pair of foot alignment struts located on the upper rear surface of the base wherein the distance between a first foot alignment strut and a second foot alignment strut is at least 10.0 inches;

a pair of vertical struts located on the upper rear surface of the base wherein a first vertical strut is located on an outer exterior portion of the first foot alignment strut and a second vertical strut is located on an outer exterior portion of the second foot alignment strut; and

a pair of grips attached to the pair of vertical struts and located at least 15 inches above the base.
