Abstract

The invention discloses a single-camera flame three-dimensional reconstruction depth estimation method based on optical flow, which can perform three-dimensional depth estimation on flames under complex working conditions and detect the combustion state of the flames. The problems that in a traditional flame three-dimensional reconstruction algorithm, the calculation cost is high, experimental equipment is expensive, and experimental operation is complex are solved, and a new thought is provided for flame monitoring under the complex working condition. A black baffle is used as the background of a flame combustion environment built in the design, it is guaranteed that the background of a shot flame image is single, a camera is used for conducting video collection and then transmitting the video to a computer for frame extraction, and the extracted flame image is firstly subjected to denoising processing; and performing semantic segmentation by using a network trained in advance, then performing optical flow estimation, and finally converting an obtained optical flow graph to obtain a three-dimensional depth map.

Description

technical field [0001] The invention belongs to the technical field of flame video image segmentation, and relates to a single-camera flame three-dimensional reconstruction depth estimation method based on optical flow. Background technique [0002] The three-dimensional model of the flame has extremely important applications in the industrial field. The three-dimensional reconstruction of the flame can help people understand the temperature distribution of the flame and the sufficient degree of combustion more intuitively. It is of great significance for the study of the flame propagation mechanism and the dynamic simulation of the flame model. [0003] In fossil fuel power plants, burner combustion performance analysis is required to improve the efficiency of fuel combustion, ensure the safety of boilers, and reduce the emission of polluting waste. Therefore, it is necessary to establish a three-dimensional model of the combustion flame, and then analyze the combustion cha...
