THREE-DIMENSIONAL (3D) RECONSTRUCTION DEVICE AND METHOD OF FLAME SPECTRA - A simplified explanation of the abstract

This abstract first appeared for US patent application 20230421746 titled 'THREE-DIMENSIONAL (3D) RECONSTRUCTION DEVICE AND METHOD OF FLAME SPECTRA

Simplified Explanation

The patent application describes a device and method for reconstructing three-dimensional flame spectra. The device consists of multiple prism-mask shooting systems and mirrors that are set up around a combustion area. The mirrors reflect the flame data into the prism-mask shooting systems, allowing for real-time acquisition of hyperspectral data from multiple angles. The method involves acquiring and preprocessing hyperspectral data of the flame and using a 3D reconstruction algorithm to reconstruct the spectral data of the flame.

• The device has multiple prism-mask shooting systems and mirrors.
• Mirrors are tilted on the left and right of the shooting system axis.
• Data of the flame is reflected by the mirrors into the prism-mask shooting systems.
• Real-time acquisition of hyperspectral data of the flame is achieved from multiple shooting angles.
• The method involves acquiring and preprocessing hyperspectral data of the flame.
• A 3D reconstruction algorithm is used to reconstruct the spectral data of the flame.

Potential Applications

• Flame monitoring and analysis in industrial processes.
• Fire safety and prevention systems.
• Combustion research and optimization.
• Environmental monitoring of wildfires and controlled burns.

Problems Solved

• Traditional flame monitoring methods are limited to two-dimensional data.
• Lack of real-time acquisition of hyperspectral data from multiple angles.
• Difficulty in accurately reconstructing three-dimensional flame spectra.

Benefits

• Real-time acquisition of hyperspectral data from multiple angles improves accuracy.
• Three-dimensional reconstruction provides a more comprehensive understanding of flame spectra.
• Enables better analysis and optimization of combustion processes.
• Enhances fire safety and prevention measures.

Original Abstract Submitted

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.
