Hand position recognition device for elevator

The invention provides a hand position recognition device for an elevator. The hand position recognition device is low in cost and small in transformation amount and uses a non-contact operation mode. The device comprises an interface board; particularly, the device also comprises a hand position recognition host; the hand position recognition host comprises a shell, a main control board, at least one two-dimensional laser ranging module and at least two cameras; each two-dimensional laser ranging module and each camera are both connected with the main control board; the main control board communicates with the interface board by a cable; the orientation of the scanning surface of the two-dimensional laser ranging module is the same as the orientation of the camera; the main control board judges a target intention key position according to distance information provided by the two-dimensional laser ranging module and direction information provided by the camera and executes conduction of the key position throu
