How would one approach the problem to extract information like the biggest diameter, smallest diameter, number of wholes, the diameter of wholes, widths, length, etc. from engineering drawing?
I'm interested in the general approach to such a problem. Which algorithms, etc. are best suited?
Problems I see:
- Different graphical symbols used to encode things like welding areas
- Text is separated from an area where it belongs to but attached via arrows
- rotated text
- specifying which information to extract, not everything is needed
The output would be a table where the features are in columns and the different drawings are per line.
