US 2026/0112191 A1 · TABLE RECOGNITION METHOD AND RELATED DEVICE THEREFOR

Abstract

This application discloses a table recognition method. The method includes: a target image including a to-be-recognized table can be first obtained. The target image can be processed using a target model, to separately obtain a plurality of cells of the table, first location information of the plurality of cells, and second location information of a plurality of separators between the plurality of cells. Text recognition can be further performed on the target image, to obtain a plurality of texts of the table and third location information of the plurality of texts. Then, fourth location information of the plurality of cells can be determined based on the second location information of the plurality of separators. Finally, the location information can be comprehensively considered, to complete matching between the plurality of cells and the plurality of texts, so as to obtain the table.
