[0019] see figure 1 , the method for converting tables in images into electronic tables proposed by this application includes the following steps.
[0020] Step S1: Convert and correct the image according to the text line and table line information in the image. For example, the text in the image is usually arranged horizontally, and the table lines usually include horizontal lines and vertical lines. Due to the shooting angle and the bending of the paper, the text and table lines in the image may be tilted and distorted. This step detects the angle of the text line and the table line, and arranges each line of text in the image approximately horizontally, so that the lines close to the horizontal are approximately horizontal, and the lines close to the vertical are approximately vertical. Perform rectification and correction. The image processed in this way can improve the accuracy of the subsequent detection of the position of the form and the correct rate of the structure...
