Lytro Illum Calibration Dataset

Calibration datasets used in the article Standard Plenoptic Cameras Mapping to Camera Arrays and Calibration based on DLT. These datasets were acquired with a Lytro Illum camera using two calibration grids with different sizes: 8 × 6 grid of 211 × 159 mm (Big Pattern) with approximately 26.5 mm cells, and 20×20 grid of 121.5 × 122 mm (Small Pattern) with approximately 6.1 mm cells. Each dataset acquired is composed of 66 fully observable poses of the calibration pattern. The datasets contain images with objects in order to evaluate the rectification in images not used during the calibration. Care was taken to avoid changing the focal settings of the camera.本文《Standard Plenoptic Cameras Mapping to Camera Arrays and Calibration based on DLT》（即《标准全光相机（Plenoptic Camera）映射至相机阵列及基于直接线性变换（Direct Linear Transform, DLT）的标定》）中所使用的标定数据集，均采用Lytro Illum相机采集。本次采集使用两款不同尺寸的标定棋盘格：其一为8×6规格、尺寸211×159 mm的大图案（Big Pattern），其方格单元边长约为26.5 mm；其二为20×20规格、尺寸121.5×122 mm的小图案（Small Pattern），其方格单元边长约为6.1 mm。每个数据集均包含66组标定图案可被完全观测的相机位姿采集样本。此外，数据集还涵盖带有其他物体的图像，用于评估标定阶段未使用图像的图像校正效果。实验过程中严格避免更改相机的焦距设置。
