What is a Time of Flight 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 of objects three-dimensionally.
-
Differences from a conventional camera sensor
The use of extensive distance information enables the sensor to identify its peripheral environment. Thanks to its depth of field it can register for more than a traditional camera sensor. You’ll get a better idea of distance and dimension.
