The method comprises the following steps: converting number plate color images of the armed police automobiles into gray level images; performing binaryzation and character segmentation; reconstructing adhered police marks WJ of license plates of the armed police automobiles into characters 'WJ', and reconstructing administrative district codes from 00 to 34 with small dimension on license plate images into novel characters from '00' to '34'; performing trimetric projection on binarized images in the horizontal direction, the vertical direction and the spatial overlooking direction; forming character characteristic values through calculation; and quickly matching the character characteristic values with character characteristic values in a standard word stock so as to accurately recognize fuzzy characters. The method has the advantages that: the method does not perform character ...

The invention discloses a template matching method based on the global features of a scene, which is used for inspecting similar objects in images according to a target template. The method comprises the following steps: extracting searching subgraphs which are within the same template images range from ergodic per-pixel of scene images; counting the relevance of each searching subgraph and the template image; selecting candidate objective pixels according to the standard that the higher the relevance of one searching subgraph and the template image is, the larger possibility for the ergodic pixel corresponding to the searching subgraph to be an objective pixel is; and determining the final objective pixel from the candidate objective pixels. The invention is characterized in that the method counts the relevance of the searching subgraphs and the template image by utilizing the global features, and the global features are obtained by putting the relevance of the templates and the subgraphs ...

The invention relates to a method for determining a rib laying manner of a reinforced retaining wall based on a sand box model test. Initial rib laying parameters of a wallplate are calculated out by establishing a sand box model of a simple interface model and through the Rankine earth pressure theory and the mechanism of action of a reinforced retaining wall, thus a wallplate with pull ribs is manufactured; an earth pressure model loading test is carried out, the number of arrangement layers of the pull ribs is gradually reduced, the rib laying parameters are calculated again, the earth pressure model loading test is repeated, and the optimized number of layers of the pull ribs, the horizontal intervals of all the layers and the vertical positions of all the layers are obtained; the length of the pull ribs is gradually reduced, and the earth pressure loading test is repeated until the optimized length of the pull ribs is obtained. According to the method for determining the rib laying ...
