摘要:
矿井火灾视觉检测面临的主要挑战包括复杂多变的矿下环境导致的误报或漏报，以及拍摄角度、距离和环境条件变化对图像识别的干扰。在工程实际中，仅依赖温度或形状等单一信息来判别火焰容易对光源和热源误报为火焰。针对上述问题，为了有效识别早期火源并对干扰源进行识别，提出基于双光谱成像技术的矿井火源识别及抗干扰方法，根据火焰的温度信息和形状信息来分别识别出火焰、干扰光源、干扰热源。实验结果表明，光源、干扰热源和火源的边缘图海明距离很大在[30，64]，可以用来区分火焰、光源和干扰热源，通过对同一火焰可见光与红外的边缘图海明距离标定，得到的海明距离[0,25]范围可认为其为同一火焰，（25，30）判断为不同位置类似火焰，[30，64]认为为不同物体疑似光源或者疑似热源。根据不同光谱边缘图海明距离的取值范围，从而实现对矿井火焰、干扰火源、干扰热源的精准分类和识别。
Abstract:
Visual detection of mine fires faces several major challenges, including false alarms or missed detections caused by the complex and variable underground environment, as well as interference with image recognition due to changes in shooting angles, distances, and environmental conditions. In engineering practice, relying solely on single information such as temperature or shape to identify flames can easily lead to false alarms where light sources and heat sources are misidentified as flames.To address these issues and effectively identify early fire sources while recognizing interference sources, a method for mine fire source identification and anti-interference based on dual-spectral imaging technology has been proposed. This method identifies flames, interfering light sources, and interfering heat sources based on both the temperature and shape information of the flame. Experimental results show that the Hamming distance differences between the edge images of light sources, fire sources, and interfering heat sources are significantly large, ranging from [30, 64], which can be used to distinguish flames from mine light sources and interfering heat sources. By calibrating the Hamming distance between the visible light and infrared edge images of the same flame, a Hamming distance range of [0, 25] can be considered as the same flame, (25, 30) as similar flames at different positions, and [30, 64] as different objects suspected to be light sources or suspected heat sources.Based on the Hamming distance value ranges of different spectral edge images, this approach achieves precise classification and identification of mine flames, interfering fire sources, and interfering heat sources.
