Abstract
To address the problems that the probe easy wears,the scanning speed is slow and the scalability is poor during contact measurement for the precision measurement process,a fin shape precision measurement system is developed based on virtual instrument and laser triangulation. The measurement principle of the fin dimensions is analyzed.The hardware architecture,software architecture,data acquisition,filtering algorithms and other key technologies of the test systemare studied.The specific radius measurement evaluation method is given.
