The invention discloses a
hybrid optimization
algorithm-based parameter calibration method of an articulated arm
coordinate measuring machine, and belongs to the field of precision measurement methods. According to the method, firstly, a
mathematical model of the articulated arm
coordinate measuring machine is established on the basis of a D-H model, then a
hybrid genetic least square optimizationalgorithm (GA-LM) used for
model parameter solving is designed on the basis of a
genetic algorithm (GA) and a least square method (LM), and finally, the designed
hybrid genetic least square optimization
algorithm (GA-LM) is adopted for parameter calibration on the articulated arm
coordinate measuring machine. The hybrid optimization
algorithm (GA-LM) adopted in the method fuses the advantages ofthe
genetic algorithm (GA) and the least square method (LM), parameter calibration can be effectively carried out on the articulated arm coordinate measuring
machine, calibration accuracy is high, nosupport of external
measuring equipment is needed at the same time, costs are low, and operation is simple.
