【Abstract】 The 3-D measurement system of free-form surface is made up with single CCD video cameral by employing line-structured laser. Some key technologies are discussed such as video cameral calibrating, laser plane calibrating 3-D coordinate computing of measured object and data fusion of multiple view measurement. In coordinate computing, multiple variables non-linear optimized problems with constraint are changed into least squares problems of linear equation group utilizing screw theory, which simplifies the computing complexity and advanced stability in solving course. Finally in this paper, experiment research is performed and experiment result is presented.更多还原
