ToF camera is one of the main technology types currently used in 3D depth cameras. The depth camera, also known as a 3D tof sensor, is an imaging device that can obtain distance data through visual data.
ToF camera is to continuously send light pulses to the object to be measured, and then use the sensor to receive the light signal returned from the object to be measured, and obtain the distance information of the object to be measured by detecting the round-trip flight time of the light pulse.
Compared with the dual-camera (binocular vision) solution for depth measurement, the ToF solution has the advantages of small system algorithm requirements and small size, and is widely used.
ToF technology has been very mature as an application for assisting smartphone cameras to focus quickly. Compared with other technologies, tof camera solutions can also be used for distance measurement accuracy. For example, robot vacuum can detect and recognize objects and build room maps to achieve the best Route selection, shorten working time, increase coverage, avoid incomplete operations, collisions and jams under obstacles.
