Converts a Time-of-Flight (ToF) distance image to a PointSet using the pinhole camera model for coordinate computation. The intrinsic parameters of the camera (FocalLength, PrincipalPoint, InterPixelDistance) are set via SetIntrinsicParameters(). The measured distance for each pixel corresponds to the distance between the object point and the corresponding image point on the image plane. If a subset of indizes of the image is defined via SetSubset(), the output PointSet will only contain the cartesian coordinates of the corresponding 3D points. More...

Detailed Description

Converts a Time-of-Flight (ToF) distance image to a PointSet using the pinhole camera model for coordinate computation. The intrinsic parameters of the camera (FocalLength, PrincipalPoint, InterPixelDistance) are set via SetIntrinsicParameters(). The measured distance for each pixel corresponds to the distance between the object point and the corresponding image point on the image plane. If a subset of indizes of the image is defined via SetSubset(), the output PointSet will only contain the cartesian coordinates of the corresponding 3D points.

The coordinate conversion follows the model of a common pinhole camera where the origin of the camera coordinate system (world coordinates) is at the pinhole

The definition of the image plane and its coordinate systems (pixel and mm) is depicted in the following image
