Dataset Description
We introduce a challenging dataset for identifying machine parts from real photos, featuring images of 102 parts from a labeling machine. This dataset was developed with the complexity of real-world scenarios in mind and highlights the complexity of distinguishing between closely related classes, providing an opportunity to improve domain adaption methods. The dataset includes 3,264 CAD-rendered images (32 per part) and 6,146 real images (6 to 137 per part) for UDA and testing. Rendered images were produced using a Blender-based pipeline with environment maps, lights, and virtual cameras arranged to ensure varied mesh orientations. We also use material metadata and apply one of 21 texture materials to the objects. We render all images at 512x512 pixels. The real photo set consists of raw images captured under varying conditions using different cameras, including varied lighting, backgrounds, and environmental factors.
Update:
- Fix material issues for some objects. (real was black steel but synth was natural steel)
- Add train & test estimated depth data from ZoeDepth
- Add unprocessed (uncropped) test image data with bounding box labels
- Add depth data exported from render pipeline (blender) via compositing graph. (raw EXR & normalized PNG)
- Add training images including ControlNet generated wood backgrounds
- Add training images including ControlNet generted hands
- Add training images processed by T2i-Adapter Style Transfer
