Abstract
A motion capture object that includes the use of two types of markers for tracking and identifying motion capture objects within a motion capture environment. The system includes belt markers and motion capture markers. The belt markers are configured to divide the object into separate hemispheres (e.g., a first and second hemisphere). The motion capture markers in each hemisphere are positioned in different patterns. The motion capture markers in the first hemisphere are positioned in a first pattern that is unique to the first hemisphere. The motion capture markers in the second hemisphere are positioned in a second pattern that is unique to the second hemisphere.
Claims20
A motion capture object comprising:
- a first hemisphere;
- a second hemisphere;
- a plurality of belt markers, wherein the plurality of belt markers are configured to divide the first hemisphere from the second hemisphere, wherein each of the belt markers has a first visual appearance;
- a first plurality of motion capture markers, wherein the first plurality of motion capture markers are positioned in a first configuration on the first hemisphere, wherein each of the motion capture markers of the first plurality has a second visual appearance;
- a second plurality of motion capture markers, wherein the second plurality of motion capture markers are positioned in a second configuration on the second hemisphere, wherein the first configuration and the second configuration are different, wherein each of the motion capture markers of the second plurality has the second visual appearance;
- wherein the plurality of belt markers, the first plurality of motion capture markers, and the second plurality of motion capture markers are configured to be detectable by motion capture cameras.
A computer-implemented motion capture method, the method comprising:
- acquiring motion capture data associated with a motion capture object having a first hemisphere and a second hemisphere, wherein the motion capture object comprises:
- a plurality of belt markers, wherein the plurality of belt markers are configured to divide the first hemisphere from the second hemisphere, wherein each of the belt markers has a first visual appearance;
- a first plurality of motion capture markers, wherein the first plurality of motion capture markers are positioned in a first configuration on the first hemisphere, wherein each of the motion capture markers of the first plurality has a second visual appearance;
- a second plurality of motion capture markers, wherein the second plurality of motion capture markers are positioned in a second configuration on the second hemisphere;
- synchronizing the motion capture data from a plurality of motion capture cameras;
- determining motion characteristics associated with the motion capture object based at least in part on the plurality of belt markers, the first plurality of motion capture markers, and the second plurality of motion capture markers;
- and
- outputting the motion characteristics associated with the motion capture object.
A non-transitory computer storage media storing instructions that when executed by a system of one or more processors, cause the one or more processors to perform operations comprising:
- acquiring motion capture data associated with a motion capture object having a first hemisphere and a second hemisphere, wherein the motion capture object comprises:
- a plurality of belt markers, wherein the plurality of belt markers are configured to divide the first hemisphere from the second hemisphere, wherein each of the belt markers has a first visual appearance;
- a first plurality of motion capture markers, wherein the first plurality of motion capture markers are positioned in a first configuration on the first hemisphere, wherein each of the motion capture markers of the first plurality has a second visual appearance;
- a second plurality of motion capture markers, wherein the second plurality of motion capture markers are positioned in a second configuration on the second hemisphere;
- synchronizing the motion capture data from a plurality of motion capture cameras;
- determining motion characteristics associated with the motion capture object based at least in part on the plurality of belt markers, the first plurality of motion capture markers, and the second plurality of motion capture markers;
- and
- outputting the motion characteristics associated with the motion capture object.
