Lidar (/ ˈ l aɪ d ɑːr /, also LIDAR, an acronym of "light detection and ranging" [1] or "laser imaging, detection, and ranging" [2]) is a method for determining ranges by targeting an object or a surface with a laser and measuring the time for the reflected light to return to the receiver.
Laser based lidar (LIght raDAR) technology applications in geology, seismology, remote sensing and atmospheric physics. Three-dimensional structural modifications and writing inside technological materials. [1] Lasers have been used aboard spacecraft such as in the Cassini-Huygens mission. [2]
Lidar has a wide range of applications; one use is in traffic enforcement and in particular speed limit enforcement, has been gradually replacing radar since 2000. [1] Current devices are designed to automate the entire process of speed detection, vehicle identification, driver identification and evidentiary documentation.
How Cars Use Lidar to Map for Hands-Free Driving BMW For a hands-free driving system to keep a vehicle safely in its lane, the software first needs to know where that lane is and some information ...

Mobile mapping is the process of collecting geospatial data from a mobile vehicle, [1] typically fitted with a range of GNSS, photographic, radar, laser, LiDAR or any number of remote sensing systems. Such systems are composed of an integrated array of time synchronised navigation sensors and imaging sensors mounted on a mobile platform. [2]
