Process for real-time optical character recognition in an automation system and automation system

摘要

The invention concerns a procedure (100) for real-time optical character recognition in an automation system (200), comprehensive:Detect the blocks of characters (400) in an input image (300) in a detection step (101);Determine a first time period as a time period needed to perform the detection step (101) in a first determination step (103);determine a second period as a difference between the predetermined period and the first period in a second stage of determination (105);Determine a detection period for each detected character block (400) in a third determination step (107);verify that a sum of the specified detection periods of the detected blocks (400) is greater than the second time period in a verification step (109);If the sum of the specific recognition periods of the detected blocks (400) is greater than the second time period, select from the detected blocks (400) of blocks for which a sum of the respective recognition periods is not greater than the second time period, in a selection step (111); andRecognize the character units (316) of the selected character blocks (400) within the second time period in a recognition step (113).The invention also concerns an automation system (200) to perform the process (100).
