abstract = "Using inexpensive and readily available materials -- a calibrated
pair of cameras and a laser line projector -- a 3D laser range
scanner which requires no tracking is implemented in this paper.
We introduce a planarity constraint for reconstruction, based on
the fact that all points observed on a laser line in an image are
on the same plane of laser light in 3D. This plane of laser light
linearly parametrizes the homography between a pair of images of
the same laser line, and this homography can be recovered from
point correspondences derived from epipolar geometry. Points
visible from multiple views can be reconstructed via triangulation
and projected onto this plane, while points visible in only one
view can be recovered via ray-plane intersection. The use of the
planarity constraint during reconstruction increases the system's
accuracy, and using the planes for reconstruction increases the
number of points recovered. Additionally, an interactive scanning
environment is constructed, where incremental reconstruction is
used to provide continuous visual feedback. Reconstructions with
this method are shown to have higher accuracy than standard
triangulation.",
