Abstract:
The present invention relates to the field of passenger conveyor technologies, and provides a speed detection system of a passenger conveyor and a speed detection method thereof. In the speed detection system and the speed detection method of the present invention, an imaging sensor and/or a depth sensing sensor are/is used to sense at least one part of the passenger conveyor to acquire sequence frames, and the sequence frames are analyzed by a processing apparatus to obtain at least speed information about steps of the passenger conveyor.
