Abstract

The present application provides a laser measurement system and a control method thereof. The laser measurement system includes: a laser emitting unit, multiple laser detection units and a control unit. The laser measurement system can simultaneously detect the displacement and deflection of multiple measurement points by using a laser emitting unit in conjunction with multiple laser detection units. The multiple laser detection units share a laser beam and can compensate in real time for errors caused by laser tilt, which will change synchronously in multiple detection devices. At the same time, the influence caused by structural changes can be eliminated. The installation structure is synchronously affected by environmental changes, and these synchronous changes can be eliminated by making differences between multiple detection points.
