The invention discloses a data fusion system and method based on geomagnetic sensors and a camera sensor. An edge device receives geomagnetic timestamps sent by each geomagnetic sensor arranged on a measured road and vehicle information sent by the camera sensor in real time; the vehicle information comprises a camera timestamp representing vehicle image acquisition time, a license plate, a vehicle type and a vehicle color; the edge device determines track information of each vehicle in each detection time period by using the obtained geomagnetic timestamp based on Kalman filter processing in each detection time period; determining a corresponding matched vehicle in the vehicle information by using the track information of each vehicle; and carrying out data fusion on the track information and the vehicle information of each matched vehicle in the detection time period, and uploading the fused data to an intelligent traffic cloud platform. According to the method, the geomagnetic sensor and the camera sensor are utilized to improve the information acquisition accuracy, more comprehensive vehicle driving information is obtained, the fusion algorithm complexity is low, and the cost is low.
