Abstract: The disclosure is generally directed to remotely-controlled automated vehicle parking operations. A driver of a vehicle stands on a curb and launches a software application on a handheld device. The software application uses a camera of the handheld device to capture images of the vehicle that can be observed by the driver. The software application then attempts to obtain a visual lock between the camera and the vehicle. In some cases, obtaining the visual lock may be hampered due to adverse lighting conditions. Light may be transmitted from the handheld device to illuminate the vehicle for better image capture. Alternatively, a command can be transmitted from the handheld device to a controller in the vehicle for turning on a light in the vehicle. After obtaining visual lock, various techniques such as vehicle path prediction and interpolation, can be used for effectively tracking the vehicle.
