title: Synthetic Photogrammetric Survey Dateset

description: This dataset contains a set of synthetic images, used to simulate a photogrammetric survey of everyday and cultural heritage objects.

This dataset has been used to study the influence of specular reflections on the photgrammetric reconstruction process, and to train a neural model to remove specular highlights from photos, to improve the photogrammetric reconstruction.

 

The 3D assets have been prepared to have a coherent position orientation, scale, materials, naming, and stored in individual blender files. For each asset, another blender file was created, with a configurable camera and lighting rig, to simulate camera placement and ligthing used in a photogrammetric survey. Rendering was configured to produce simultaneously 3 images: a complete rendering, a diffuse-only rendering, and a specular-only rendering. 

In this way, for each asset, it was possible to generate renderings compatible in terms of framing, resolution, lighting and appearance, to real-world photogrammetric surveys. The image triples were used to train a neural network to remove specular highlights from photos. 

 

This dataset comprises 24 assets, 144 rendered images per asset (3456 in total).

 

This dataset has been prepared by the Visual Computing Lab, CNR-ISTI (https://vcg.isti.cnr.it)

Authors: Marco Callieri, Daniela Giorgi, Massimiliano Corsini, Marco Sorrenti.

DATASET CONTENT:

 

The dataset contains two main folders, plus readme info file.

 

--IMAGES

The rendered images, simulating the photogrammetric survey.

  

One folder per asset, folder is named as the asset. 

For each asset, 48 views, 3 render per view:

  ASSETNAME_CXXX   combined rendering image

  ASSETNAME_DXXX   diffuse-only image

  ASSETNAME_SXXX   specular-only image

In total, 144 images per folder, 2000x2000 resolution.

PNG format, with transparency channel as mask.

 

 

--SCENES_ASSETS

The 3D assets and Blender scenes.

 

00_BASE.blend is the basic empty scene file, used for the inital setup of the rendering process and the lighting/camera rigs.

 

For each asset there is a blender file, named as the asset, containing the camera/lighting setup and rendering configuration to produce the combined/diffuse/specular images. Each of these blender files references its relative 3D asset from another Blender file from one of the subfolders.

    

The prepared 3D assets are stored in the subfolders named as the asset.

Each asset subfolder contains the original 3D model and texture, plus a Blender scene containing the ready-to-use asset with a standardized position, orientation, scale, naming, material and settings.
