The Time-of-Flight principle (ToF) is a method for measuring the distance between a sensor and an object, based on the time difference between the emission of a signal and its return to the sensor, after being reflected by an object.
ToF(Time-of-Flight) 원리는 물체에 반사된 신호가 방출된 후 센서로 되돌아오는 시간 차이를 기반으로 센서와 물체 사이의 거리를 측정하는 방법을 말함.
