• Abstract: This paper presents a novel calibration algorithm for Multi-Focus Plenoptic Cameras (MFPCs) using raw images only. The design of such cameras is usually complex and relies on precise placement of optic elements. Several calibration procedures have been proposed to retrieve the camera parameters but relying on simplified models, reconstructed images to extract features, or multiple calibrations when several types of micro-lens are used. Considering blur information, we propose a new Blur Aware Plenoptic (BAP) feature. It is first exploited in a pre-calibration step that retrieves initial camera parameters, and secondly to express a new cost function for our single optimization process. The effectiveness of our calibration method is validated by quantitative and qualitative experiments.

  We introduce a new approach to hand-eye calibration called EasyHeC, which is markerless, white-box, and delivers superior accuracy and robustness. We propose to use two key technologies: differentiable rendering-based camera pose optimization and consistency-based joint space exploration. Our evaluation demonstrates superior performance in synthetic and real-world datasets.

  We propose a marker-free online method for the extrinsic calibration of multiple smart edge sensors. Our method assumes the intrinsic camera parameters to be known and requires priming with a rough initial estimate of the camera poses. We show that the calibration with our method achieves lower reprojection errors compared to a reference calibration generated by an offline method.

• Leveraging blur information for plenoptic camera calibration [6.0982543764998995]
  This paper presents a novel calibration algorithm for plenoptic cameras, especially the multi-focus configuration. In the multi-focus configuration, the same part of a scene will demonstrate different amounts of blur according to the micro-lens focal length. Usually, only micro-images with the smallest amount of blur are used. We propose to explicitly model the defocus blur in a new camera model with the help of our newly introduced Blur Aware Plenoptic feature.
