Lidar (/ ˈ l aɪ d ɑːr /, also LIDAR, LiDAR or LADAR, 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.
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.
The lidar sensor is accompanied by a pair of cameras—one facing the front and the other aimed rearward—that snap a frame every few seconds to provide human and computer annotators with some ...
Lidar is a sort-of acronym that may or may not be capitalized when you see it, and it usually stands for "light detection and ranging," though sometimes people like to fit "imaging" between the ...
Time of flight of a light pulse reflecting off a target. A time-of-flight camera (ToF camera), also known as time-of-flight sensor (ToF sensor), is a range imaging camera system for measuring distances between the camera and the subject for each point of the image based on time-of-flight, the round trip time of an artificial light signal, as provided by a laser or an LED.
LIDAR can be used to detect ground surface changes. [10] Vegetation remote sensing is a principal application of LIDAR. [11] Radiometers and photometers are the most common instrument in use, collecting reflected and emitted radiation in a wide range of frequencies. The most common are visible and infrared sensors, followed by microwave, gamma ...
Intel today introduced the latest addition to its RealSense line. The L515 is roughly the size of a tennis ball, targeted specifically for warehouse logistics — a hugely important and ...
Atmospheric lidar is a class of instruments that uses laser light to study atmospheric properties from the ground up to the top of the atmosphere. Such instruments have been used to study, among other, atmospheric gases, aerosols, clouds, and temperature.
