Liquefied petroleum gas label pattern recognition system

The invention discloses a liquefied petroleum gas label pattern recognition system, and relates to the field of image enhancement. Comprising an image acquisition unit, an image processing unit, a data processing unit and an image recognition unit. The method comprises the following steps: acquiring an HSV color space image of a label image of liquefied petroleum gas, segmenting a plurality of image blocks, acquiring a dictionary vector and a first sparse vector of each image block, and adjusting each feature description value in the first sparse vector of the image block to determine a reflective feature, and calculating a reflective texture correction coefficient of each pixel point by using the feature description value of the reflective feature, performing image enhancement on the label image by combining the reflective texture correction coefficient with the required enhancement degree, and identifying the label of the liquefied petroleum gas according to the enhanced label image.
