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.

Abstract: A high-speed and high-accuracy spectral video system has a filter module that filters optical signals in desired bands; a beam splitting module that splits the signal from the filter module into two identical beams entering an encoding aperture module and an RGB information acquisition module, respectively; a dispersion module disperses the optical signal and transmits the dispersed signal to a grayscale information acquisition module; a data reconstruction module aligns the signal from the grayscale information acquisition module to the signal from the RGB information acquisition module, denoises the signals, reconstructs a video by a bilateral filtering algorithm, and sends the reconstructed video to a display module for storage and display. A flame spectrum can be reconstructed using few sampling points to obtain broad-band spectral characteristics of the flame or using many sampling points to obtain high-accuracy spectral data.
