Abstract: Provided is a recognition method of 3D vein pattern including the following steps. A plurality of first light beams are emitted by a recognition device to a wrist of a user. A plurality of first reflected light beams from the wrist are received by the recognition device to form a first 3D vein pattern of the wrist. Differences between the first 3D vein pattern and a wrist vein pattern of a database are compared to identify an identity or a gesture of the user. A recognition device of 3D vein pattern is also provided.
