Abstract

The highest workload for helicopter pilots occurs during hover and landing tasks. Thus, the precision hover mode above a ground fixed or moving target was selected for closer investigation. As a proof of concept a restricted computer vision system, which is capable of locating and tracking a square, was integrated in the fly-by-wire helicopter ATTHeS (Advanced Technology Testing Helicopter System). A square with a length of one metre was mounted on top of a car. Flight tests demonstrated the automatic stabilization of the helicopter above the moving car by computer vision. This feasibility study lead to the development of a more general computer-vision system, which is able to observe the helicopter flight state during hover and low speed, based on the detection and tracking of significant but arbitrary features. That means that no additional information about the appearance of the camera view has to be known in advance to achieve autonomous helicopter hover stabilization. The paper presents the characteristics of the two computer vision sensors.
