Abstract
A process is provided for estimating a three-dimensional (3D) radiance field of a combustion process in an enclosure. An on-line intensity-temperature calibration is performed based on an association between an intensity of an image pixel and an actual temperature associated with a selected region in the enclosure. The intensity of the corresponding image is transformed to a radiance image based on settings of an image-capturing device and the on-line calibration. A registration and alignment estimation of the image is performed based on positional information of the enclosure. The radiance image is aligned based on the registration estimation. The 3D radiance field having voxels of the enclosure is estimated based on a two-dimensional to 3D transforming of the aligned radiance images.
