A single-point laser measurement system is designed and an experiment is done to validate the method.

Improvement on measurement precision of laser probe using image optimization method;

In order to realize non-contact auto-measurement of revolving parts,an offset auto-adjustment device was de- signed by using a laser probe as the feedback control element.

A stereovision inspection system for measuring free-form surface is introduced which consists of coordinate measuring machines (CMM) and a laser probe.

A precise and fast 3D coordinate measuring machine, which is composed of a laser probe head and servomechanism with high performance, was developed utilizing precise control, positioning optimization, approximation of deceleration with three levels broken line, online position correction and smoothing algorithm.

For its advantages of high precision, fast speed, portable size, good reliability, non-contact measurement, the laser triangular measuring device is extensively used in size and distance measurement and product on-line examination.
