Abstract

In order to meet high quality measurement requirements with less cost and lesser time consumption, the sampling strategy has to be planned before the measuring device is already available. In this paper, a common 3D geometric measuring system based on laser scanning technique is presented. An measurement cost model is established by consider of several cost sources in 3D geometric measurement process. In terms of view angle of laser scanner, an optimal inspection strategy planning is developed on a circular feature too. Finally, a series of experiments on typical circular of workpieces are performed based on coordinate measuring system equipped with a laser line scanner. In case of desired measurement accuracy for the measured feature, the minimum inspection cost can be obtained by the iterative optimization algorithm, thus generating a reliable and an efficient sampling path planning. Those results are most promising for on-machine applications in optimal inspection strategy of 3D geometric of workpiece.
