Laser Scanner, Laser Scanner Measuring System, Calibration Method For Laser Scanner Measuring System And Target For Calibration |
摘要 |
A laser scanner measuring system is disclosed, which has a laser scanner and a calibration target. The laser scanner comprises a light emitting element for emitting a pulsed laser beam, a rotary projecting unit for projecting the pulsed laser beam, a distance measuring unit, and a control unit for driving and controlling the light emitting element and the distance measuring unit. The calibration target has a reflection sector with a known shape and with high reflectance and is installed at a known position. In use, there is a step for judging a reflected pulsed laser beam from the reflection sector by detecting a level of light quantity, a step for determining a center position of the reflection sector based on the result of the judgment, and a step for calibrating the laser scanner measuring system based on the determined center position and on the known position. |
