PPISP Dataset
Dataset Description:
The PPISP dataset accompanies the work "PPISP: Physically-Plausible Compensation and Control of Photometric Variations in Radiance Field Reconstruction". It contains object-centric scene captures of four outdoor scenes, each captured with three different cameras, for multi-view 3D reconstruction and novel view synthesis. The photos were captured with exposure bracketing of +/-2 EV and re-processed with automatic exposure and color corrections to create a challenging benchmark for methods that compensate for photometric inconsistencies.
Each scene has two variants: a standard version processed from the full exposure brackets, and an auto version where selected exposures were re-processed with automatic exposure compensation and white balancing, for a total of eight sequences. We also provide pre-computed COLMAP sparse reconstructions (camera poses and point clouds) for each sequence, enabling direct usage in common radiance field reconstruction methods.
The dataset is provided in two formats: COLMAP (colmap/) and NCore V4 (ncore/). Each format contains one zip archive per scene, with both the standard and auto variants as separate folders (e.g., huerstholz/ and huerstholz_auto/).
This dataset is ready for commercial/non-commercial use.
Dataset Owner(s):

Intended Usage:
Benchmarking and development of radiance field reconstruction methods such as 3DGRUT and GSplat.
Dataset Characterization
Capture
Four scenes were captured in raw format using two mirrorless camera systems (Nikon Z7, OM System OM-1 Mark II) and a smartphone (Apple iPhone 13 Pro). The captures were done in an object-centric fashion, that is, with a certain object (statue, artwork, etc.) as the main focus, with photos taken from multiple angles around it. Exposure bracketing of +/-2 EV was used. Aperture and focus were set manually and remained fixed, and image stabilization was disabled.
Processing
The raw photos were developed to JPEG using the manufacturer's recommended software (NX Studio for Nikon, OM Workspace for OM System, Adobe Lightroom Classic for iPhone), with manual white balance from a color calibration target. Furthermore, selected exposures were re-processed with automatic exposure compensation and white balancing, producing an extra four sequences for a total of eight sequences from four real-world scenes.
We used COLMAP to reconstruct camera poses and a sparse point cloud for each sequence.
Dataset Format
- COLMAP format (
colmap/): Downsampled images in JPEG format, COLMAP camera poses, COLMAP sparse point cloud. - NCore V4 format (
ncore/): NCore V4 scene archives and metadata.
Dataset Quantification
8 sequences, about 2600 photos in JPEG format total. The four standard sequences contain 500-700 images each; the four auto sequences contain 50-150 images each.
Measurement of total data storage: About 14.3 GB in compressed form (8.1 GB COLMAP format + 6.2 GB NCore V4 format).
