The invention discloses a road condition detection method based on millimeter-wave radars and cameras. The method comprises the following specific steps: S1, installing millimeter-wave radars with different working frequencies and cameras with different precisions at corresponding fixed relative positions; s2, firstly, the millimeter wave radar with the lowest working frequency is adopted to acquire millimeter wave radar point cloud data corresponding to the road condition in real time, and then whether the acquired millimeter wave radar point cloud data meet requirements is analyzed; s3, acquiring an optimal millimeter wave radar as a radar data detection basis; acquiring optimal millimeter wave radar point cloud data in real time; s4, the camera with the lowest precision is adopted, and data of the current camera corresponding to the road condition is obtained in real time; then analyzing whether the acquired camera data meets the requirements or not; s5, acquiring an optimal camera as a camera data detection basis; and S6, matching and fusing the millimeter wave radar data and the camera data according to a preset time rule. The detection precision is improved.
