文摘

A novel geometric calibration method of focused light field camera is developed. Virtual image points are calculated from raw light field images. Geometric parameters of the main lens and microlens are accurately calibrated. Three-dimensional temperature field of ethylene diffusion flames is reconstructed. The reconstruction results are validated with thermocouple measurements.
