Optical tracking marker mounting apparatus
View Patent ↗An arrangement comprises a garment, a mounting apparatus and an optical tracking marker to be used in motion capture. The arrangement may include a plurality of mounting apparatuses and optical tracking markers. The garment includes openings. The mounting apparatus includes legs which are shaped and include features to enable the mounting apparatus to engage the openings of the garment. The mounting apparatus further includes a marker coupling which is shaped and includes features to engage the optical tracking marker. The mounting apparatus provides a secure yet removable attachment for the optical tracking marker to the garment.
1. An optical tracking arrangement for a body comprising:
a garment comprising a plurality of openings with a first spacing between each of the plurality of openings;
a plurality of mounts releasably secured to the garment, each of the plurality of mounts including a plurality of legs, each of the plurality of legs engaging one of the plurality of openings in the garment with the leg extending through the opening, wherein a second spacing between tips of the plurality of legs is substantially the same as the first spacing between each of the plurality openings, each of the plurality of openings designed and dimensioned to receive one of the plurality of legs; and
a plurality of optical tracking markers positioned on the plurality of mounts.
2. The optical tracking arrangement of claim 1 wherein the garment is comprised of a compression fabric.
3. The optical tracking arrangement of claim 1 wherein each of the plurality of legs includes a barb.
4. The optical tracking arrangement of claim 1 wherein each of the plurality of legs is arcuate in shape.
5. The optical tracking arrangement of claim 1 wherein each of the plurality of legs descends outwardly from a central body portion.
6. The optical tracking arrangement of claim 5 wherein each of the plurality of mounts further includes a marker coupling positioned on the central body portion.
7. The optical tracking arrangement of claim 6 wherein the marker coupling comprises a post extending from the central body portion.
8. The optical tracking arrangement of claim 1 wherein the plurality of optical tracking markers are comprised of a retro-reflective material.
9. A device for retaining an optical tracking marker, the device comprising:
a body portion including a central top surface;
a marker coupling positioned on the central top surface of the body portion and configured to couple the optical tracking marker to the body portion; and
a plurality of legs extending outward from the body portion, the plurality of legs void of optical tracking markers and void of marker couplings configured to couple optical tracking markers to the legs, and each of the plurality of legs substantially arcuate in shape.
10. The device of claim 9 wherein each of the plurality of legs includes a barb.
11. The device of claim 10 wherein the body portion is a central body portion having a substantially cylindrical shape, and wherein each of the plurality of legs extends radially and axially away from the central body portion.
12. The optical tracking arrangement of claim 11 wherein the marker coupling comprises a post extending from the central body portion in an axial direction.
13. A method of mounting an optical tracking marker on a body, the method comprising:
donning a garment comprising a plurality of openings with a spacing between each of the plurality of openings;
positioning a plurality of mounts to the garment by inserting legs on each of the plurality of mounts into the plurality of openings in the garment with each of the plurality of openings designed and dimensioned to receive one of the legs, each leg extending through one of the plurality of openings, and a spacing between tips of the plurality of legs substantially the same as the spacing between each of the plurality openings; and
positioning a plurality of optical tracking markers on the plurality of mounts.
14. The method of claim 13 wherein the plurality of optical tracking markers are positioned on the plurality of mounts before the plurality of mounts are positioned on the garment.
15. The method of claim 13 wherein the garment is donned after the plurality of mounts are positioned on the garment.
16. The method of claim 13 wherein the legs include arcuate portions and wherein positioning the plurality of mounts to the garment includes inserting tips of the legs into the openings of the garment and rotating the mounts such that the legs more fully engage the openings in the garment.
17. The method of claim 13 wherein positioning the plurality of optical tracking markers on the plurality of mounts includes inserting a post on each of the plurality of mounts into a cavity on each of the plurality of optical tracking markers.
18. The optical tracking arrangement of claim 1 wherein the diameter of each of the plurality of openings is substantially larger than a distance between garment fibers in areas of the garment removed from the openings.
19. The optical tracking arrangement of claim 1 wherein the openings are spread out over a substantial entirety of the garment.
