Abstract
Aiming at the precision requirement of pin detection of electronic connectors in modern industry
the method of laser triangulation for reconstruction of three-dimensional information of objects and point cloud processing is studied
and a detection device is designed to measure the coplanarity of the pins of connectors. The device consists of a laser
a camera and an one-dimensional mobile platform
it is low cost and has simple structure. Two typical kinds of connectors are selected for testing. The accuracy of type I connector is 99. 6 %
and the repeatability precision is 0. 022 mm. Experiments show that it can be applied in detection of various types of connector coplanarity.
