Laser-based measurement equipment for positioning e.g. pipe driving machine, has computer to automatically inquire angles and lengths of machine, where angles and lengths are used for positional computation of machine

摘要

The equipment has a pressing pit in which a laser beam is installed, where the beam optically calibrates height, side and direction of a driving machine. A traverse is developed in a tube line by interlinked intermediate laser stations. A computer automatically inquires angles and lengths of the machine, where the angles and lengths are utilized for positional computation of the machine.
