The invention relates to a table recognition method and device. The table recognition method comprises the steps of obtaining a to-be-recognized table image; performing line segment detection on the table image to obtain a plurality of transverse line segments and a plurality of vertical line segments; determining a plurality of cell transverse line segment sets in different longitudinal position ranges from the plurality of transverse line segments based on the transverse projection information of each transverse line segment in the plurality of transverse line segments; based on the longitudinal projection information of each vertical line segment in the plurality of vertical line segments, determining a plurality of cell vertical line segment sets in different transverse position ranges from the plurality of vertical line segments; and generating a target table based on the intersection point position of each transverse line segment in the plurality of cell transverse line segment sets and each vertical line segment in the plurality of cell vertical line segment sets, and the transverse line segment and the vertical line segment to which each intersection point position belongs. By adopting the method, the accuracy of table recognition can be improved.

The application discloses a kind of reconstruction method, device and storage medium of picture missing line table based on OCR, belong to picture processing technical field.The reconstruction method includes: S1, all texts in table are clustered according to ordinate, and all texts are divided into different lines;S2, line coordinates are constructed, and the position corresponding to the mean value of the ordinate of the first intermediate coordinate value of two adjacent lines is regarded as the first demarcation of two adjacent lines of text;S3, column coordinates are constructed, and the position corresponding to the mean value of the abscissa of the second intermediate coordinate value of two adjacent columns is regarded as the second demarcation of two adjacent columns of text;S4, the position coordinates of line recognized by OCR are compared with the coordinates of second demarcation, if matching, then display vertical line.The application reconstructs missing line table according to the position information of missing line table text and line, and improves the restoration degree of missing line table.
