SCANNING IN THE 21ST CENTURY

摘要

Advances in sensor electronics and hardware technology to process data have made mobile LiDAR scanning (MLS) systems more affordable, accurate, flexible, and easily deployable. Improvements in the speed and accuracy of positioning hardware-specifically global navigation satellite system (GNSS) receivers and inertial measurement unit (IMU) sensors-have made MLS an effective and efficient way to quickly capture high-resolution 3-D topographic data over large areas. Such factors have contributed to MLS increasingly being chosen as a go-to method for surveying, especially in the transportation sector.
