Claim 13:
14. The system of claim 12, wherein the step of extracting 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 a table region associated with the table in the pre-processed engineering drawing document using the table location based on a predefined criteria;
performing rescaling on the table region using a predefined scale factor to obtain a rescaled table;
applying thresholding on the rescaled table using a thresholding technique to obtain a clear table;
performing erosion of the clear table to obtain an eroded table;
extracting text data present in each cell of the eroded table using a data mapping mechanism; and
performing masking of the table region associated with the table in the pre-processed engineering drawing document.
