8.The methodology of real time image processing of laservision sensing seam tracking system has been studied. For the key technology in laser stripe extraction and character point detection, feasible method has been proposed.
9.The principles of the laservision alignment is introduced,and elaborates on the method of 3D coordinates measurement of the tip,namely,multi curve fitting in the light plane with least square theory.
10.In order to study the effect of metal fabric and distortion of work piece in tungsten inert gas (TIG) welding rapid prototyping and obtain the height and variety range of metal parts, the method of the laservision detecting was used to establish a detecting system to analyze the obtained image.
