The invention provides a vehicle converse running detection device and method based on SVM. A classifier is innovatively used for detecting vehicle converse running. Classification is conducted through the combination with various characteristics including gravity centers, speeds, accelerated speeds, areas, perimeters, the minimum external rectangles and the like, on tracks, of vehicles, and the classification accuracy can be effectively improved. Considering that the probability of converse running happening on roads is generally low, in order to obtain more converse running samples, forward running samples are innovatively used as the converse running samples after the sequence is inverted and are then combined with original samples, the converse running samples are effectively supplemented, and the problem that the number of positive samples and the number of negative samples are not even can be effectively solved.
