Description
Dataset description: Calibration images under different lighting conditions - static mode for feature detection
Calibration photos under different lighting conditions. The set includes a geometric calibration matrix, a color standard, a spectrometer and a lamp with a variable lighting spectrum. 10 static images were taken in each of the 12 sessions. The light spectrum was measured in each session. The results of the light spectrum measurements can be found in each folder respectively. Calibration results from each session for the same camera are in the same folder named the sesion number.
