Abstract
The invention discloses a laser detecting device for large-scale scanning. The laser detecting device comprises a first driving mechanism, a rotating table, a second driving mechanism and a signal device. The rotating table is arranged on the first driving mechanism which drives the rotating table to rotate around the X axis. The second driving mechanism makes the rotating table reciprocate up and down in the X-axis direction. The signal device is fixed to the rotating table and rotates and reciprocates together with the rotating table. The signal device comprises a transmitter and a receiver. Lasers transmitted by the transmitter are projected to a target object and form a continuous wavy track on the target object. The receiver receives lasers reflected by the target object and judges the position of the target object relative to the laser detecting device. The transmitter can scan target objects at different heights and in different directions in space by rotating and reciprocating.
