Problems solved by technology

[0002] A pie chart is a type of chart, mainly composed of a sector, sector description text (percentage or number), legend text, legend, and title. Currently, image processing technology is used to extract information in a pie chart. Image The effectiveness of the processing method depends entirely on the image quality of the image to be processed. If the image quality is high, the accuracy of information extraction will be high, otherwise, the accuracy will be low.
That is to say, the accuracy of the information extraction in the current pie chart cannot be guaranteed

Abstract

The present invention relates to an information extraction method and device in a pie chart. The method includes the following steps: detecting each element and its position information in the pie chart to be processed, the elements including text elements and legend elements; Elements and legend elements are recognized for text, and the text information corresponding to the text element and the legend text contained in the legend element are respectively obtained; according to the detected elements, their position information, and the legend text, the sector information and legend information are obtained, and the sector information One-to-one correspondence with the legend information; the sector information includes the sector color and the proportion of the sector in the pie chart, and the legend information includes the legend color and its corresponding legend text. The method and device of the present invention detect each element in the pie chart and identify text information through deep learning, the information extraction is accurate, and is not affected by the image quality of the pie chart, providing a set of simple and effective solution.
