Referring to 3D measurement methods like grating projection measurement, which make 3D output data arranged in
parallel lines, the topic brings forward an algorithm to reconstruct surface that represented in triangle geometry model
more efficiently, easily and automatically than those for 3D scattered points do. The algorithm select pairs of matched
points from every 2 neighbor lines dynamically, each point from one line. The line made up of a pair of matched points
is called skeleton line. Those skeleton lines can be expected as parallel as possible. Then the 4 end points in 2 neighbor
Skeleton lines can construct 1 quadrangle, also 2 good-characteristic triangles as elements of triangle geometry model.
Also the method is improved to avoid surface gap problems.
