The measurement of moving state of individual vehicle is necessary to grasp automobile traffic flow. Recently the image-processing type vehicle detector system has been noticed as a new sensor. However, as it is very difficult in real time processing and moreover it has particular technical problem for image-processing at outdoor environment, it has not been sufficiently utilized. In this paper, we propose a vehicle detecting method using wave form analysis on space frequency domain which signal is a brightness distribution from TV monitor. The features of our method are simple system construction because detection is achieved using finite frequency components and its Spectrum ratio. At the end of this paper, the certitude and robustness of this method has been verified with recognition experiments.
