Laser scanning

8 articles · The principle of TOPODRONE LiDAR operation is based on measuring the distance from the laser source center to the object. The laser beam coming out of the emitter is reflected from the surface of the object being inspected. The reflected signal goes to the scanner receiver, where the time delay (pulse method) between the emitted and reflected signal determines the required distance. Knowing the coordinates of the scanner, which we get thanks to the built-in GNSS receiver TOPODRONE and high-precision IMU, as well as the direction of the laser beam impulse, you can determine the three-dimensional coordinates of the point from which the pulse was reflected. TOPODRONE LiDAR provide the ability to generate measurement pulses with a frequency from 300,000 per second to 1,920,000 per second, using a system of moving mirrors (TOPODRONE Avia) or the scanner body itself spinning(TOPODRONE 100, TOPODRONE 100+, TOPODRONE 200+, TOPODRONE Hi Res, TOPODRONE ULTRA, TOPODRONE HDL) to distribute these pulses over the entire surface of the object. As a result of such measurements or “scanning” we obtain in a short time a cloud of three-dimensional points, describing with high accuracy and completeness the object under investigation.
