Face recognition system and method based on big data

The invention provides a face recognition system and method based on big data, and the system comprises the steps: building a face recognition data a recognition system which is connected with a CPU, is provided with an enhancement algorithm module in the CPU, and is used for being connected to the database; the control part is configured as follows: (i) when the recognition system receives a face recognition image task, the control part calls the processing part to divide a face recognition image into a plurality of recognition units, loads a database at the same time, sets up a recognition resource reference library according to the priority, and sends the recognition resource reference library to the processing part; the identification system identifies the identification unit on the basis of the identification resource reference library; or (ii) when the recognition system recognizes the recognition units on the basis of the recognition resource reference library and the recognition result is not obtained
