Acquiring Image and Skeletal Data Using Kinect
12-19
MetaData Description
JointWorldCoordinates This is a 20 x 3 x 6 double matrix of x-, y-
and z-coordinates for 20 joints, in meters
from the sensor, for the six possible
skeletons, if the BodyPosture is set to
Standing. If it is set to Seated, this
would be a 10 x 3 x 6 double for 10 joints.
See step 9 for the syntax on how to see
this data.
PositionDepthIndices A 2 x 6 double matrix of X and Y
coordinates of each skeleton in pixels
relative to the depth image.
PositionImageIndices A 2 x 6 double matrix of X and Y
coordinates of each skeleton in pixels
relative to the color image.
PositionWorldCoordinates A 3 x 6 double matrix of the X, Y and Z
coordinates of each skeleton in meters
relative to the sensor.
RelativeFrame This 1 x 1 double represents the frame
number relative to the execution of a
trigger if triggering is used.
SegmentationData Image size double array with each pixel
mapped to a tracked/detected skeleton,
represented by numbers 1 to 6. This
segmentation map is a bitmap with pixel
values corresponding to the index of the
person in the field-of-view who is closest
to the camera at that pixel position. A
value of 0 means there is no tracked
skeleton.
