This presentation outlines our vision on the D-Reader, the product our company develops. The product is focused on automated understanding of engineering drawings.
2. 1. To get the exact information on an object’s parts and assemblies, its volumetric
model and composition
2. To get exact information about materials and components of the object
3. To be able to obtain all information from the drawings and convert it into a 3-D
model in a compatible software package.
The drawing must be converted to the selected format. Thus, DII’s AI platform has to
read the information from the available drawings in a similar way to a human.
Tasks
3. 0. Prepare the drawing for recognition. “De-noise” the drawing and “vectorise” the
image (converting from a raster to a vector image).
1. Define the drawing’s functional areas
2. Recognise signs and symbols
3. Distinguish service graphics from the object’s dimensions
4. Relate geometry with service signs and symbols
5. Turn 2-D views and the material library into a precise 3-D model
Steps
4. 0. De-noise and vectorise
The images are prepared for future work. In most
cases we can use available algorithms and
integrate them into our software.
11. 1. Define the drawing’s functional
areas
Using computer vision-(CV) trained software, we
will be able to determine key functional areas of
the drawings. Existing CV object and area
detection algorithms will be used. Training will be
required for the engineering drawings’ domain.
16. 2. Recognise symbols and special
signs
Existing text and symbol detection algorithms will
be used. It needs knowledge transfer for the
engineering drawings’ domain.
26. 4. Relate geometry with service
signs and symbols
Combine computer vision and standard rules of
automatic reading. R&D is still required with
software implementation according to ISO
standards.
33. 5. Turn 2-D views and bill of
materials into a 3-D model
Combine a digital view projection with a bill of
materials (BOM)
Requires BOM digitisation and
object assembly algorithms
