Abstract

As high brightness of laser spot, it significantly distinguish from the other goals on objects surface. Therefore, in computer vision, laser spot often is applied as interaction tools, and an important measurement tool etc. In building large-scale multi-projection display system, accurate measurement of geometrical parameters is very important. Based on subdivision mesh, this paper presents laser spot tracking algorithm with sub-pixel precision. The experimental data validates this algorithm sub-pixel precision.
