The time of the trip, combined with information regarding the angle of the sensor and the altitude, allows Buckeye to generate a 3D coordinate at the target. The combined efforts of both sensor systems transforms the collected images into a compressed, georeferenced, and colored mosaic, which can then be used to create a 3D map of the area. [2]
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 ...
Airborne Lidar Bathymetric Technology-High-resolution multibeam lidar map showing spectacularly faulted and deformed seafloor geology, in shaded relief and coloured by depth. The airborne lidar bathymetric technological system involves the measurement of time of flight of a signal from a source to its return to the sensor. The data acquisition ...
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.
Stereo triangulation is an application of stereophotogrammetry where the depth data of the pixels are determined from data acquired using a stereo or multiple-camera setup system. This way it is possible to determine the depth to points in the scene, for example, from the center point of the line between their focal points.
Currently, the best source for nationwide LiDAR availability from public sources is the United States Interagency Elevation Inventory (USIEI). [1] The USIEI is a collaborative effort of NOAA and the U.S. Geological Survey, with contributions from the Federal Emergency Management Agency, the Natural Resources Conservation Service, the US Army Corps of Engineers, and the National Park Service.

Unlike RADAR which relies on doppler shifts to directly measure speed or LIDAR which relies on the principle of time-of-flight to calculate speed, VIDAR measures the speed of vehicles by means of tracking an object through vision cameras. High precision speed measurement can be achieved if stereoscopic vision techniques are used.
