The invention discloses a data processing method and a data processing system with system detection and image identification functions. The method comprises the following steps that: data of application projects is collected; 2, data in a main data table and each sub data table in a project application database is read, and whether the data conforms to requirements or not is judged; and 3, project data conforming to the requirements in the second step is synchronized into a review database from the project application database, projects conforming to the requirements are subjected to three times of screening, and data of a final award-winning project stored in a third cache region of the review database is output. The method and the system have the data judgment advantages that the system automatically extracts duplicate checking factors for carrying out complex matching calculation; artificial factors are reduced; the correctness of duplicate checking results is improved; the workload of workers is reduced; and the work efficiency is greatly improved.
