Automatic registration method, device and system for pattern spots of global comprehensive renovation

The invention discloses an automatic registration method, device and system for pattern spots of global comprehensive regulation. The device comprises a pattern spot acquisition unit, a registration screening unit and a parameter calculation unit. The system comprises a user input module, an automatic registration module and a result generation module. The method comprises the following steps: performing registration scoring and score backtracking on interior angles in a first interior angle sequence and a second interior angle sequence which are registered by applying a Smith-Waterman algorithm and a vacancy weight constant model, and performing screening to obtain a first registration result with the highest registration degree and a first reference pattern spot corresponding to the first registration result; and calculating an affine parameter group between the first reference pattern spot and the first pattern spot to be registered so as to complete registration. With the automatic registration method, de
