Smart laser profiler automatic in leveling and direction adjustment

The invention belongs to the technical field of geometric dimension measurement and specifically relates to a smart laser profiler automatic in leveling and direction adjustment. The smart laser profiler automatic in leveling and direction adjustment comprises an electric revolving stage, a wireless communication module, first and second speed reducing step motors, a bearing block with a bearing, a three-dimensional electronic compass and a laser distance measuring sensor. The smart laser profiler realizes automatic leveling and direction adjustment by means of direction indication of the three-dimensional electronic compass and thereby well solving the problems in the prior art. The laser profiler is capable of measuring the form of the section of a tunnel in real time in tunnel construction to determine back break, and also capable of performing long-term monitoring on the tunnel section form after the completion of tunnel construction; the laser profiler is high in accuracy, simple and convenient to operate, and convenient for reuse after dismounting; and the laser profiler is capable of well performing self-leveling and direction correction for base dislocation and torsion caused by geological changes during tunnel monitoring, and further realizes remote control.
