What is the difference between laser tracker and three-coordinate measurement principle?

Based on the laser technology, the laser tracker scans the object with the laser beam emitted by the laser, receives the reflected laser signal through the receiver, and calculates the position and attitude information of the object through the processing algorithm. It is mainly used to measure and track the three-dimensional position and posture of objects.

The coordinate measuring machine uses the probe to contact the surface of the object, records the coordinate information of multiple measuring points, and obtains the relevant measurement data of the object through calculation. It is used to measure the size, shape and position of objects. Able to complete complex measurement tasks and provide detailed geometric data.

Laser tracker can not only measure the size and shape tolerance of large workpieces, but also perform dynamic tracking and attitude calibration, while three-coordinate only measures the size and shape tolerance.

In a word, the choice of laser tracker or CMM depends on the specific measurement requirements and application scenarios, and the appropriate measuring equipment can achieve more efficient and accurate industrial production.
