Systems, methods, and computer-readable media are disclosed for determining a distance between a vehicle and a computing device during a remote parking operation. An example method includes receiving, by a computing device, a 3D model of a vehicle and vehicle inertial data. The method also includes capturing an image of the vehicle. The method further includes determining a distance between the computing device and the vehicle based on the image and the 3D model, and updating the distance based on the vehicle inertial data.
