question about kinect_visionsensor filter dialog
Posted: 24 Jul 2014, 10:11
Hi Marc,
I have been experimenting with the kinect sensor to obtain a depth map of the scene, but i am confused by the returned values in the "show filter dialog-->Extract coordinates from work image" whose return values are:
(1) point count along X
(2) point count along Y
(3) point1 x
(4) point1 y
(5) point1 z
(6) distance point 1
...
Originally I though x,y are coordinates in the x-y plane which are perpendicular to the direction of the infrared ray
and z should be the depth value. But after retrieving all the points of a scene, I found out x and z contains negative values where y is always positive, which means y is the depth value, is it?
I also want to know where is the origin of the plane, which is perpendicular to the infrared ray.
and what does distance point1 mean?
Thanks a lot in advance!
Yours sincerely,
Juekun
