Abstract
Concerning about the defects that the current DSP based traffic flow detection algorithm has poor real time performance and high miss detection rate,an improved single-frame image differential algorithm was proposed. The proposed method is based on the TMS320DM642 DSP platform and realized underground parking lot traffic flow video detection. Differential operation is applied on the gray value of one detection line in a single frame image. The characteristics of the vehicles are extracted by the analysis of the gray value to make one dimension processing possi⁃ble,taking place of conventional two dimension processing. In addition,the algorithm utilizes the dual-frame back⁃ground to relieve the miss detection rate. The experiment result shows that the algorithm complexity is reduced by 3 orders and the accuracy reaches 93%which proves the proposed algorithm to be a practical and efficient method.关键词
