Summary:The invention discloses a method for identifying dangerous goods marks based on template matching. The method is applied to a post-disaster site after dangerous goods explosion. The method mainly comprises the steps of video acquisition, format conversion, image initialization, contour extraction, region of interest extraction, template matching and the like, and can be used for identifying various different dangerous goods marks. Compared with the prior art, the method has the following technical characteristics and advantages: 1) the method for identifying the dangerous goods marks through template matching is provided, the recognition time is about 1s, and at most three pictures of the dangerous goods marks can be identified at the same time; 2) a template matching method combining a FAST operator and a Sift operator is adopted, the matching precision is greatly improved, and 3) the image edge is solved by calculating the characteristic value of the gradient field, so that the effect of rapidly and accurat
