| Abstract: | Magnetometer detector is a new type of vehicle information detection equipment based on the changes of magnetic field. A method of traffic flow information detection was proposed based on this magnetometer detector. The preprocessing and the steps of feature extraction of the coilection data were introduced. The method to distinguish the vehicle based on threshold value was discussed by using 2 magnetoresistive sensors. A real-time experimental test of the traffic flow was conducted. The experimental results show that the accuracy of the vehicle detection method based on magnetoresistive sensors can be as high as 96%. |
