Static pose fixture
View Patent ↗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.
1. A system for measuring a person who is a subject of a motion capture model, the system comprising:
a static pose fixture comprising
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;
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. 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 within a static pose fixture comprising
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;
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.
