Enhancing Camera Operator Performance with Computer Vision Based Control

Cameras are often mounted on platforms that can move like rovers, booms, gantries and aircraft. People operate such platforms to capture desired views of scene or target. To avoid collisions with the environment and occlusions, such platforms often possess redundant degrees-of-freedom. As a result, manipulating such platforms demands much skill. Visual-servoing some degreesof-freedom may reduce operator burden and improve tracking performance. This concept, which we call human-in-the-loop visualservoing, is demonstrated in this paper and applies a filter and feedforward controller to a broadcast camera boom.
