Real-time 3D sensing of distance to humans or objects using OMRON B5L


What is TOF Sensor?

A TOF (Time of Flight) sensor uses the flight time of light to measure distances to objects. As well as being able to turn captured images into 3D images, it can also measure at a speed of 20 frames per second, allowing it to track the movement objects three-dimensionally.

Differences from a conventional camera sensor

The use of extensive distance information enables the sensor to identify its peripheral environment

Ambient Light Immunity
