Abstract

The invention discloses a chart information extraction method and device and a storage medium, and the method comprises the steps of obtaining a to-be-extracted information chart, and carrying out thepreprocessing of the to-be-extracted information chart; extracting a transverse frame line and a longitudinal frame line of the preprocessed to-be-extracted information chart based on an opening andclosing operation principle; performing intersection operation on the extracted transverse frame lines and the extracted longitudinal frame lines, and obtaining intersection points of the to-be-extracted information chart; determining a minimum identification unit of the to-be-extracted information chart based on the intersection point, the transverse frame line and the longitudinal frame line ofthe to-be-extracted information chart; and performing text recognition on each minimum recognition unit in the to-be-extracted information chart to obtain chart information of the to-be-extracted information chart. The key information in the image table can be efficiently, flexibly and accurately extracted, and the technical effect of improving the working efficiency of power grid safety monitoring personnel for examining the related image table is achieved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of image recognition, and in particular to a method, device and storage medium for extracting graph information. Background technique [0002] The daily power production and operation and maintenance process is usually accompanied by a large number of graphic tables. On the one hand, these charts can be used to record various data, and on the other hand, some charts can also be used to guide standardized operations. [0003] However, these image tables have the characteristics of large number, fixed format, strong correlation between tables, and scattered key information to be checked, which greatly affects the work efficiency of grid security inspectors in reviewing these image tables. Contents of the invention [0004] The invention provides a graph information extraction method, device and storage medium, which can not only efficiently, flexibly and accurately extract the key i...
