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 (/ 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.
In April 2017, Velodyne introduced its Velarray, a compact fixed-laser solid-state sensor that produces a directional image rather than the surround view provided by Velodyne's previous sensors. [42] The range, resolution, and directional field of view of the Velarray enable improved object detection and longer braking distances than the ...
Small object detection is a particular case of object detection where various techniques are employed to detect small objects in digital images and videos. "Small objects" are objects having a small pixel footprint in the input image. In areas such as aerial imagery, state-of-the-art object detection techniques under performed because of small ...
The sensor captures the light backscattered from objects (either fixed or moving) over its detection area, and processes the signals to precisely map their location and other attributes. The data is compiled thousands of times per second, providing up to a few hundred frames per second and offering accurate and reliable information even in ...
The TriDAR sensor is a hybrid 3D camera that combines auto-synchronous laser triangulation technology with laser radar (LIDAR) in a single optical package. This configuration takes advantage of the complementary nature of these two imaging technologies to provide 3D data at both short and long range without compromising on performance. [ 9 ]
