摘要： A method of performing geometrical measurements of remote objects includes performing a laser sweep of a measurement object with a handheld sensor device including a distance measurement unit and an inertial measurement unit. The method includes activating the distance measurement unit to perform a plurality of distance measurements during the laser sweep, and activating the inertial measurement unit to perform an inertial measurement in association with each of the distance measurements. A processor is used to process the distance measurements with reference to the associated inertial measurements to determine a geometric characteristic of the measurement object.
