Laser Radar:Figure 1 shows a MV351, a “Laser-Radar” system manufactured by Nikon Metrology, in which the laser beam is steered by rotating around horizontal and vertical axes. This unit sends a distinct, focused laser pulse to an object and reads the return signal as described above. Unli...

Laser and Scanning Sensor— LiDAR sensors (英文) send out laser pulses within the green or near-infrared bands, sweeping terrain side-to-side, and collecting range data. Specialized GPS receiver— Highly accurate GPS receivers track plane location as well as altitude which is then integrated with...
It has previously been shown that unmodelled systematic errors can exist in modern terrestrial laser scanners that deteriorate the... Chow,CK Jacky,Lichti,... 被引量: 22发表: 2013年 Improving calibration accuracy of structured light systems using plane-based residual error compensation The ...
In the proposed approach, a random sample consensus (RANSAC)-based plane fitting technique was utilized for plane extraction, and cross-feature points were extracted from the polar view transform of segmented planes. To resolve the discontinuity problem of optimization, a nonlinear optimization method ...
The actual calculation for measuring how far a returning light photon has travelled to and from an object is quite simple:Distance = (Speed of Light x Time of Flight) / 2The LiDAR instrument fires rapid pulses of laser light at a surface, some at up to 150,000 pulses per second. A ...
A type of lidar that is designed to measure the Rayleigh scattering of laser light from molecules in the atmosphere, thereby determining atmospheric density. McGraw-Hill Dictionary of Scientific & Technical Terms, 6E, Copyright © 2003 by The McGraw-Hill Companies, Inc. ...
2.2. Plane in LiDAR-Based SLAM In LiDAR SLAM, planes are one of the most common environmental features. Obtaining the position and geometric information of planes from laser data can be used to perceive the surrounding environment and build maps, providing crucial information for robot localization...
