Abstract
Vehicles, such as vehicles in an open-pit mine, are visually tracked. The location of a vehicle is determined using radio frequency signals, such as pseudolite transmissions of ranging signals. The camera is steered based on the location. For example, multiple cameras are directed automatically on a vehicle based on the vehicle position. Images from a plurality of perspectives are provided to resolve or prevent a problem. The directing may include zooming for better viewing of vehicles at different distances from the camera. The directing may be incorporated into a vehicle management system, such as a dispatch system. For example, a user selects a vehicle from a list of managed vehicles or a displayed map, and the cameras are steered to view the selected vehicle based on the position of the vehicle.
