Engineering Diagram Graph Annotation
Label StudioImageBounding BoxFixed PriceProject Overview
You should be comfortable reading technical/engineering diagrams and interpreting symbols, connectors, and line crossings. Prior experience with annotation tools that support bounding boxes and region-to-region relations (e.g., Label Studio or CVAT) is required, and you must be consistent and detail-oriented when labeling complex, large images. Comfort working at full resolution and producing clean, guideline-compliant labels is essential. Nice to have: experience annotating object-detection or graph/relationship ML datasets. For each engineering diagram sheet, you will label all symbol nodes with classified bounding boxes (7 symbol classes) and annotate special routing/helper nodes (connector bends/junctions and crossing line intersections). You will also label edges between symbols to represent connectivity, marking each edge as solid or non-solid. You will export annotations in the requested format (Label Studio JSON / CVAT XML / COCO) using the same coordinate frame as the source images.
