Contract comparison method, robot and system based on AI identification

The invention relates to a contract comparison method, robot and system based on AI identification. The contract comparison method based on AI identification comprises the steps of obtaining a contract scanning copy of a signed contract and a corresponding electronic contract file which passes online approval; performing quality evaluation, automatic deviation correction, image processing and layout analysis on the contract scanning copy to obtain each layout area of the contract scanning copy; intelligently identifying each layout area of the contract scanning copy, and analyzing data and position information, corresponding to each layout area, of the electronic contract file; intelligently comparing the corresponding layout area with the data to obtain a difference point; and visually marking the difference points. According to the invention, automatic identification and comparison of contracts can be realized, the identification rate is high, and the problem of huge workload of manual proofreading is solve
