Abstract
A face identification system includes a transmitter, a receiver, a database, an artificial intelligence chip, and a main processor. The transmitter is used for emitting at least one first light signal to an object. The receiver is used for receiving at least one second light signal reflected by the object. The database is used for saving training data. The artificial intelligence chip is coupled to the transmitter, the receiver, and the database for identifying a face image from the object according to the at least one second light signal and the training data. The main processor is coupled to the artificial intelligence chip for receiving a face identification signal generated from the artificial intelligence chip.
