Position and velocity of walking pedestrian
pedestrian— Pedestrian target
Pedestrian target model, specified as a
T— Duration of next walking interval
Duration of next walking interval, specified as a positive scalar. Units are in seconds.
ANGH— Pedestrian heading
Heading of the pedestrian, specified as a scalar. Heading is measured in the xy-plane from the x-axis towards the y-axis. Units are in degrees.
BPPOS— Positions of body segments
Positions of body segments, returned as a real-valued 3-by-16 matrix. Each column
represents the Cartesian position,
[x;y;z], of one of 16 body
segments. Units are in meters. See Body Segment Indices for the column
representing the position of each body segment.
BPVEL— Velocity of body segments
Velocity of body segments, returned as a real-valued 3-by-16 matrix. Each column
represents the Cartesian velocity vector,
[vx;vy;vz], of one of 16
body segments. Units are in meters per second. See Body Segment Indices for the column
representing the velocity of each body segment.
BPAX— Orientation of body segments
Orientation axes of body segments, returned as a real-valued 3-by-3-by-16 array. Each page represents the 3-by-3 orientation axes of one of 16 body segments. Units are dimensionless. See Body Segment Indices for the page representing the orientation of each body segment.
Body segment indices define which columns in
BPVEL contain the position and velocity data for a specific body
segment. The indices also point to the page of
BPAX containing the
orientation matrix for a specific body segment. For example, column three of
BPPOS contains the 3-D position of the left lower leg. Page three of
BPAX contains the orientation matrix of the left lower leg.
