Embodiment 1

[0049] figure 1This is a flowchart of a method for identifying a chart provided in Embodiment 1 of the present invention. This embodiment is applicable to the case of recognizing graph data in text files of various formats. The graph recognizing method proposed in this embodiment can be executed by a graph recognizing device, and the graph recognizing device can be performed by software and / or hardware. Implementation can be configured in computer equipment, for example, computing equipment such as servers, personal computers, mobile terminals, etc., and the method specifically includes the following steps:

[0050] S110. Acquire a text file containing chart data.

[0051] In this embodiment, the chart data includes image data composed of tables, pure table data, etc., wherein the image data composed of tables may include a line graph class generated according to the table data, a bar graph class (eg Column charts, histograms, stacked column charts, etc.), column and bar cha...

Embodiment 2

[0104] figure 2 This is a structural block diagram of a chart recognition device provided in Embodiment 2 of the present invention, and the device can be implemented by software and / or hardware. The device includes: a data acquisition module 201, a format conversion module 202 and a chart identification module 203, wherein,

Abstract

The invention discloses a chart recognition method, device, equipment and storage medium. The method includes: acquiring a text file containing chart data; converting the text file into a picture in a preset format; inputting the picture into a chart positioning detector, and outputting The positioning result of the chart data in the picture; wherein, the chart positioning detector is obtained by training a preset neural network through a sample data set containing sample chart data. The text file containing chart data in the present invention can be a text file of any format and type, and converting the text file into a picture avoids the need to use a standard protocol to parse the text to locate the chart position in the prior art. If the picture is directly input into the pre-trained chart positioning detector, the positioning result of the chart data in the picture can be directly output, which can solve the problem that the existing technology is inefficient in identifying charts from text files and the accuracy of identifying charts is low. question.

Description

technical field [0001] Embodiments of the present invention relate to image recognition technology, and in particular, to a method, device, device, and storage medium for chart recognition. Background technique [0002] In the field of data analysis, it is most intuitive to obtain effective information from chart data. The morphological analysis of chart data is often one of the important analysis methods in finance, scientific research and other industries. The effectiveness of its data analysis has also been obtained in all walks of life. Extensive validation. [0003] Since the chart data is generally attached to the text file, it is often necessary to extract the charts in each text file separately when using the chart data for analysis. However, the traditional chart extraction method, one is based on CPU computing equipment for processing, which needs to parse the text file in advance, which leads to high time cost, slow extraction speed and long time. The format of ...
