Abstract

The invention discloses a picture processing method and device, a storage medium and computer equipment. The method comprises the steps of obtaining a to-be-processed original picture; performing graying and adaptive threshold binarization denoising on the original picture, and identifying table horizontal lines and table vertical lines in the original picture through an expansion and corrosion method so as to acquire an intermediate picture only containing table lines; obtaining cell closed contours in the intermediate picture based on a method for searching for the closed contours to form atable point picture, wherein each cell closed contour is represented by four points of a maximum bounding rectangle; obtaining four vertexes of the outermost side of the table point picture; and obtaining a corrected picture through affine transformation and the positions of the four vertexes. The method can solve the problems that in the prior art, table line cutting is prone to making mistakes,and table lines cannot be well restored.

Description

Technical field [0001] The present invention relates to the technical field of picture processing, in particular to a picture processing method, device, storage medium and computer equipment. Background technique [0002] In the daily office process, it is often necessary to process images. For example, in financial work, converting the scanned financial statements in pdf format or picture format into excel documents in tabular format is a problem that workers often face. [0003] In the prior art, general tools such as pdf or image transfer to excel can be used. However, because the scanned financial statements are usually poor in definition, the content may be skewed or distorted when scanned. This general tool is mainly to cut the table points , It is easy to cause errors in the cutting of the table line, and the table line cannot be restored well. In the financial statement, it has a great impact on the final recognition result. Summary of the invention [0004] For this reason...
