Abstract
Aimed at rack contact measurement
a method of small-module rack measurement based on machine vision is proposed.A machine vision measurement system is established.The system controls the movement of the rack with the grating
while the CCD is taking photos of the rack to realize the measurement for the whole rack.The images is analyzed by Matlab
and the edge of the rack is obtained.The basic parameters of the rack such as p and s
assessment of parameters related to the rack is calculated.The experiment turns out that the precision of this method can meet the requirements for the measurement of such rack
providing technical support for the rack online testing.
