烟气是火灾过程中的重要物理现象。为改进早期火灾探测和预警，需要对基于图像探测的火灾烟气模式加以研究。以不同应用背景为依据，对烟气模式提出分类研究的思想。并以提高图像探测的可靠性和灵敏度为目的，对烟气的图像信息特征进行分析，提出了建立早期火灾烟气模式的设想。
Smoke is an important physical phenomenon in the process of fire. In order to improve early fire detection and warning, fire smoke patterns based on image detection need to be studied. Based on different application backgrounds, this paper proposes the concept of taxonomic study on the smoke model. In order to improve the reliability and sensitivity of image detection, the characteristics of the image information of smoke are analyzed, and the idea of establishing an early fire smoke pattern is proposed.
