Operation of the system is based on the hole surface coordinates measurement by point laser triangulation sensors.
The system contains 3-6 point laser triangulation sensors located circumferentially in one housing at known fixed angles (see Figure 1).

The system operates as follows.
The measurement system is inserted into the pipe and moved by translation module to the definite position. Laser sensors measure distances to the inner surface. Software calculates inner diameter of the pipe.
