Tof structured light
WebbTime of Flight (ToF) This technique uses camera which illuminates scene using modulated light source and observes reflected light signal. The source can be either CW or pulsed usually sinusoidal or square wave in shape. There are two types of ToF techniques viz. direct ToF and Indirect ToF.

Stereo vision (SV) involves the use of two cameras, with a known separation between them, that take images from two angles to reconstruct a 3D image. This includes the illumination for night vision
Webb11 maj 2024 · 3D vision technology has been gradually applied to intelligent terminals ever since Apple Inc. introduced structured light on iPhoneX. At present, time-of-flight (TOF) and laser speckle-based structured light (SL) are two mainstream technologies applied to intelligent terminals, both of which are widely regarded as efficient dynamic … WebbToF system is a kind of light radar system, which can transmit light pulses from the emitter to the object. The receiver can determine the distance of the measured object by …
