Abstract
An image processing system renders, displays and provides virtual user navigation through multiple size and aspect views of a three-dimensional (3D) geometric model of an object, such as an urban scene. A user interface, such as a mouse or joystick device, is coupled to a digital image processor and is employed to supply image manipulation signals to the digital image processor for manipulating images displayed upon a digital image display device. The digital image display device contains an overview display window that displays the object from a ‘bird's eye’ or map perspective, and an inset display window that displays the object from a ‘down inside the scene’ perspective. In response to user interface-sourced commands, the processor can swap the two image perspectives and/or controllably navigate through the inset image.
