Vehicle location function is the basic component of many new applications of Internet of Vehicles. The accuracy and reliability of positioning will directly affect the application effect. The traditional vehicle location method is to use the satellite positioning and navigation system for positioning, but in the case of satellite signal failure (tunnel, urban canyon, the environment is blocked scene), the traditional vehicle location method is obviously not applicable. In this paper, a vehicle location method based on roadside radar and GPS is proposed. The transformation equation of radar coordinates and geodetic coordinates in 3D Cartesian Coordinate System is established by using Least Squares Method through multiple calibration points in advance. The radar coordinates of vehicle are transformed into geodetic coordinates through a series of coordinate transformation, and then a large number of radar coordinates of vehicles can be quickly and accurately converted into geodetic coordinates, which lays a foundation for vehicle location service.
