Even though the process of constructing and manufacturing a workpiece gets more and more automated, the design and use of technical drawings is still not fully integrated in the automated production process. Technical drawings accompany the workpiece throughout its life cycle and are important for additional information which is typically not part of the CAD-model, for example tolerances and regulatory standards. Goal of this master thesis is to provide a system which is able to extract textual information from technical drawing in order to process this data and automatically generate a user interface which can be used as support for measurement and quality control of workpieces. This is done by extracting textual data from the drawings, clustering these using DBSCAN and post-processing these elements to get essential dimensioning requirements. Additionally, relevant regulatory standards are extracted and added to the user interface to provide employees with all necessary information to measure and assess the quality of a given workpiece. An evaluation of the prototype shows that overall more than 70% of relevant dimensions can be extracted, whereby this value is dependent on the complexity and layout of the drawings. In addition, design guidelines are developed to optimize the readability of drawings for machines as well as for humans and additional application scenarios are explored.
