LIDAR Speed-Measuring Device Performance Specifications
www.nhtsa.govLIDAR - (from Light Detection And Ranging) the technology of measuring target range using reflected light. In today's engineering usage LIDAR includes many intricate devices, but this standard is concerned with class of LIDAR devices that determine target range and speed from the time-of-flight of laser pulses. 1.4.19
Fundamentals of Surveying
giswin.geo.tsukuba.ac.jpAngle Measuring Measuring distances alone in surveying does not establish the location of an object. We need to locate the object in 3 dimensions. To accomplish that we need: 1. Horizontal length (distance) 2. Difference in height (elevation) 3. Angular direction. An angle is defined as the difference in direction between two convergent lines. A
