Method and apparatus for orienting image representative data
View Patent ↗A method for processing a three-dimensional image file captured directly from a live subject, the file including the cranium of the subject, comprises: providing a vertex point cloud for the three-dimensional image file; determining a median point for the vertex point cloud; determining a point on the cranium; and utilizing the median point and the cranium point to define a z-axis for the three-dimensional image file.
1. A method for processing a three-dimensional image file captured directly from a live subject, said file including the cranium of said subject, comprising:
providing a vertex point cloud for said three-dimensional image file;
determining a median point for said vertex point cloud;
determining a point on said cranium by selecting a point on said vertex cloud furthest away from said median point, said selected point having predetermined characteristics.
utilizing said median point and said cranium point to define a z-axis for said three-dimensional image file.
2. A method in accordance with claim 1 , comprising:
computing an x-axis and a y-axis for said three-dimensional image file.
3. A method in accordance with claim 2 , comprising:
computing said x-axis and y-axis orthogonal to said z-axis.
4. A method in accordance with claim 1 , wherein:
said predetermined characteristics are selected such that the z-axis and y-axis coordinates of said selected point.
5. A method in accordance with claim 4 , comprising:
orienting said z axis with a reference axis.
6. A method in accordance with claim 5 , comprising:
determining said reference axis utilized to orient a plurality of three-dimensional image files acquired directly from a corresponding plurality of live subjects.
7. A method in accordance with claim 6 , comprising:
selecting one of said plurality of three-dimensional image files as a reference file;
registering all of said plurality of three-dimensional image files to said reference file; and
aligning all of said plurality of three-dimensional image files.
8. A method in accordance with claim 7 , wherein:
said aligning step comprises averaging all of said plurality of three-dimensional image files to produce a new reference file and re-aligning all of said plurality of three-dimensional image files to said new reference file and repeating the averaging and realigning steps until there is no significant change to produce a final reference file.
9. A method in accordance with claim 8 , comprising:
orienting all of said plurality of three-dimensional image files to said final reference file; and orienting said three-dimensional image file to said final reference file.
