Robot servoing from video rate data inputs is now possible. Area Parameter Acceleration techniques allow computers to isolate and geometrically describe as many as 255 objects each 33 millisecond video frame time. From the parameters of each object, the host processor may determine size, location, orientation, and shape. It then may recognize appropriate objects and select the right target for robot action.
One of the major deficiencies in current robot control schemes is the lack of high-level knowledge in the feedback loop. Typically, the sensory data acquired are fed back to the robot controller with minimal amount of...

The author presents an image acquisition and processing system designed for real-time six-dimensional object tracking with the precise temporal semantics and low latency required for use within the feedback loops of robotic applications. To achieve real-time performance, the system must extract from the image only the information needed to accomplish the task. Successful task performance depends on an integrated system, rather than on a collection of components. The hardware design takes the form of two large complementary VME-compatible cards: TRIAx, capable of simultaneously acquiring and processing two high-resolution video streams, and JIFFE, capable of 20 MFLOPS for the three-dimensional calculations. Described are algorithms that enable the system to track a rectangular solid, intended to track objects held by a robot hand. The algorithms hinge on scanning only small line segments of the image, followed by techniques for reconstructing object location from sparse edge points. The system tracks a cardboard box.
If robots must function in unstructured environments, they must also possess the ability to acquire information and construct appropriate models of the unknown environment. This paper addresses the automatic generatio...
