ConvNet-Based Optical Recognition for Engineering Drawings
Andrew Brock, Theodore Lim, James Millar Ritchie, Nick J. Weston · 2017
End-to-end machine analysis of engineering document drawings requires a reliable and precise vision frontend capable of localizing and classifying various characters in context. We develop an object detection framework, based on convolutional networks, designed specifically for optical character recognition in engineering drawings. Our approach enables classification and localization on a 10-fold cross-validation of an internal dataset for which other techniques prove unsuitable.
