Rekonstruktion von Hochkontrastvideos mittels Mehrkamerasystemen

High Dynamic Range (HDR) Stereo Datasets

Overview

Stereo high dynamic range (HDR) imaging offers a promising solution to overcome the dynamic range limitations often encountered in conventional cameras, particularly when capturing scenes with high contrast or varying lighting conditions. In contrast to traditional methods relying on temporal exposure bracketing, which can be unsuitable for dynamic scenes or HDR video, stereo HDR imaging introduces a novel framework leveraging a spatial exposure bracketing approach facilitated by a stereo camera setup. The dataset comprises HDR image data captured using a stereo camera configuration, enabling spatially distributed exposure bracketing across the two cameras. This setup allows for the capture of HDR images of dynamic scenes and facilitates HDR video production through a frame-by-frame operating principle. The dataset not only serves as a valuable resource for researchers and practitioners in the field of HDR imaging but also offers opportunities for exploring novel applications and methodologies, such as HDR video processing, scene reconstruction, and quality assessment techniques.

Datasets

Dataset LMS Pillars:

Artificially created and rendered video sequence using Blender. It consists of 2 camera views with 54 frames each. Furthermore, every frame is available in 7 different exposures. The spatial resolution of each frame is 960×540 pixel.

  • First frame of the LDR video for the left camera view:

LMSPillars-Datensatz (672MB)

 

Dataset IIS Jumble:

This dataset of a static scene has been acquired using a motorized XY translation stage and comprises 15 camera views (5×3). For each view, 5 different exposures as well as a calibration image are available. The spatial resolution of each image is 2560×1920 pixel.

  • Example for the left camera view. View 12 with normal exposure after rectification:
  • Example for the right camera view. View 13 with lower exposure after rectification:
  • Tonemapped HDR image which has been computed using the left and right camera view:
