Smoke concentration detection method fusing HSL space and improved dark channel technology

The invention discloses a smoke concentration detection method fusing an HSL space and an improved dark channel technology, and the method comprises the steps: carrying out the brightness adjustment of a foggy image in the HSL space, and improving a calculation method of atmospheric light and transmissivity in a dark channel prior theory, so as to obtain a more precise transmissivity value; the relation between the image transmissivity and the smoke concentration is obtained through multiple groups of real experiments. Experimental results show that compared with the concentration measured by an electrochemical sensor, the average error of the image smoke concentration obtained based on the algorithm is controlled to be about 5.8%, and high accuracy is achieved. In addition, the method has the effect of reducing the negative influence of illumination and background images on smoke concentration measurement. 本发明公开了一种融合HSL空间和改进暗通道技术的烟雾浓度检测方法，首先在HSL空间中对有雾图像进行亮度调整，改进暗通道先验理论中大气光和透射率的计算方法以获得更为精确的透射率值，通过多组真实实验获取图像透射
