Content:

This dataset contains a static scene representing an artistic view of a boat floating on an ocean made of colored blocks, near a temple, while a giant is chasing them. The dataset consists of two sub-datasets, one with a linear camera movement and the other with a grid of positions. Both sub-datasets showcase the same scene and are in the format of plenoptic images extracted from ray files. The dataset was acquired with two Raytrix cameras [1], the R8 and the R32, mounted on the UPM’s robotic bench. The distance between the two optical axis is (60.7079, -15.7349, 137.849)  millimeters with focals F=25 for the R8 and F=50 for the R32.

The dataset additionally contains calibration images of a checkerboard and white images taken with different main lens apertures.

 

1. Linear Camera Movement Sub-dataset:

    - Camera moves from (x, y, z) = (655, 0, 410) to (655, 450, 410) with a step of 10mm. 

2. Grid Sub-dataset:

    - Camera positions range from x=535 to x=775 per line, with a step of 10mm, and from z=350 to z=370 with a step of 10mm.

3. Calibration images:

    - Cameras are fixed at the central position (x, y, z) = (655, 0, 410) and capture views of a checkerboard with 12mm square size.

    - Overexposed images with a light diffuser were captured with varying camera apertures.

Both sub-datasets follow the format of `{R8 or R32}_z{z position}_y{y position}_x{x position}_Processed.png`. Calibration files are provided in XML format. The datasets were acquired with the UPM’s robotic bench.

The dataset contains:

- A `linear` folder containing:

  - XML calibration files

  - Plenoptic images in PNG format

- A `grid` folder containing:

  - XML calibration files

  - Plenoptic images in PNG format

- A `checkerboard` folder containing:

  - XML calibration files

  - Plenoptic raw and processed images in PNG format of checkerboard with square size of 12mm.

- A `white` folder containing:

  - XML calibration files

  - Plenoptic raw images in PNG format of overexposed images captured with a white diffusor and different main lens apertures.
