Vehicle Recognition Based on Region Growth of Relative Tension and Similarity Measurement of Side Projection Profile of Vehicle Body

Current vehicle recognition methods are less concerned simultaneously with: (1) the scale difference between vehicles and other objects in urban city; (2) impact of physical characteristics vehicles. Based on region growth relative tension, a method for measuring similarity side projection profile vehicle’s body is proposed recognizing First, tension used to divide 3D point clouds into series spatial regions. Point these regions projected 2D plane. Then, relevant features extracted, including sizes Screening by features, part regions, inside them which conforms measurement conditions selected. Quantitative evaluations selected data set show that algorithm achieves recall, precision, F-score 0.837, 0.979, 0.902, respectively, Comparative studies demonstrate superior performance algorithm.
