【Abstract】 Aiming at the problem exisfing in rapid measurement of the spatial hole system,a solution based on the principle of laser displacement detection is proposed. A set of measurement systems are designed and a mathematical model based on laser displacement sensor is built. The genetic algorithm is used to quickly fit the surface contour of the hole. On the basis of comparative measurement,the position and inner diameter information of the ectopic hole on the part is obtained by coordinate transformation. The feasibility of the system is verified by constructing a spatial heterotopic hole measurement system.更多还原
