Claim 4:
5. The processor implemented method of claim 2, wherein the step of extracting, by the DDEMS via the one or more hardware processors, text data present in each cell of the one or more cells of the table in the table location as table data using the data extraction algorithm comprises:
extracting, by the DDEMS via the one or more hardware processors, a table region associated with the table in the pre-processed engineering drawing document using the table location based on a predefined criteria;
performing, by the DDEMS via the one or more hardware processors, rescaling on the table region using a predefined scale factor to obtain a rescaled table;
applying, by the DDEMS via the one or more hardware processors, thresholding on the rescaled table using a thresholding technique to obtain a clear table;
performing, by the DDEMS via the one or more hardware processors, erosion of the clear table to obtain an eroded table;
extracting, by the DDEMS via the one or more hardware processors, text data present in each cell of the eroded table using a data mapping mechanism; and
performing, by the DDEMS via the one or more hardware processors, masking of the table region associated with the table in the pre-processed engineering drawing document.
