The invention provides a mobile device and an integrated face recognition system thereof. The integrated face recognition system comprises a shell and a central processing unit in the shell. The central processing unit is configured to unlock or not unlock the mobile device according to the comparison result. The face recognition system is arranged in the shell. The face recognition system comprises a three-dimensional structured light emitting device, and the three-dimensional structured light emitting device is configured to emit a three-dimensional structured light signal to a to-be-recognized target outside the shell. And the first neural network processing unit outputs a comparison result to the central processing unit according to the processing of the input sampling signal. The sensor is configured to perform three-dimensional sampling on a three-dimensional structured light signal reflected by a target to be identified and directly input a sampled signal to the first neural network processing unit. According to the invention, face recognition can be carried out only according to the sampling signal, an excellent result is provided, and the problems of insufficient memory, low cost and low security in the prior art are solved.
