Abstract
A three-dimensional (3D) reconstruction device and a method of flame spectra are provided. The device has a plurality of prism-mask shooting systems and a plurality of mirrors. The prism-type shooting systems are set up around a combustion area to be reconstructed and each is provided with two mirrors which are tilted on the left and right of an axis of the shooting system, so that data of a flame are reflected by the mirrors into the prism-mask shooting systems, thus realizing the real-time acquisition of hyperspectral data of the flame from multiple shooting angles. The reconstruction method includes following steps of acquiring, by a calibration cylinder, an area to be reconstructed, synchronously acquiring and preprocessing hyperspectral data of a flame, and finally reconstructing 3D spectral data of the flame by a 3D reconstruction algorithm of flame spectra.
