How does 3D Time-of-Flight (TOF) camera work?

A 3D time-of-flight (TOF) camera works by illuminating the scene with a modulated light source, and observing the reflected light. The phase shift between the illumination and the reflection is measured and translated to distance.

What is 3D time of flight sensor?

3D time of flight (ToF) is a type of scanner-less LIDAR (light detection and ranging) that uses high power optical pulses in durations of nanoseconds to capture depth information (typically over short distances) from a scene of interest.

What is the use of ToF 3D camera?

Time-of-Flight advantages

By using active Time-of-Flight (ToF) technology to sense depth, the 3D ToF camera collects non-intrusive depth image data, meaning that personal identity can never be captured.

How does a time-of-flight laser scanner work?

Time-of-flight systems: Also known as a pulse measurement system, this works by emitting a single pulse of laser light and determining the distance to the end point by measuring the time it takes for the light to be reflected back to a sensor on the scanner.

Is ToF the same as LiDAR?

How Are LiDAR and ToF Different? The functional difference between LiDAR and other forms of ToF is that LiDAR uses pulsed lasers to build a point cloud, which is then used to construct a 3D map or image. ToF applications create "depth maps" based on light detection, usually through a standard RGB camera.
