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.

The utility model relates to the technical field of teaching aids, and discloses a chessboard teaching aid. The chessboard teaching aid comprises a chessboard grid and coordinate axes arranged on the chessboard grid, the chessboard grid comprises an odd number of vertical transverse lines and vertical lines which are distributed at equal intervals, the lengths of the transverse lines and the vertical lines are equal to the number of the lines, intersection points of the transverse lines and the vertical lines located in the center of the chessboard grid are sky elements, and coordinate origins of the coordinate axes coincide with the sky elements. And the axis of the coordinate axis coincides with the horizontal line and the vertical line in the center. According to the chessboard teaching aid, the chessboard is combined with number axes, rectangular coordinates, limit coordinates and the like in mathematics to assist mathematics teaching, so that teaching content is easier to understand.

The embodiment of the application discloses a single line graph extraction method, wherein, the low-voltage primary main wiring diagram is converted into a binary graph; a first corrosion and then expansion processing is performed on the binary graph to obtain a second graph; the horizontal lines and the vertical lines are extracted from the second graph respectively to obtain a third graph containing only the horizontal lines and a fourth graph containing the horizontal lines and the vertical lines; an outer contour extraction operation is performed in the fourth graph to obtain a first outer contour set; in the first outer contour set, a first outer contour satisfying a first preset condition is determined; the third graph is cut by the first outer contour to obtain a fifth graph; an outer contour extraction operation is performed in the fifth graph to obtain a second outer contour set; in the second outer contour set, a first group of outer contours satisfying a second preset condition is determined; and based on the two outer contours corresponding to the maximum longitudinal spacing, a single line graph in the low-voltage primary main wiring diagram is extracted.
