A Natural Interaction Interface for UAVs Using Intuitive Gesture Recognition

Abstract

The popularity of unmanned aerial vehicles (UAVs) is increasing as technological advancements boost their favorability for a broad range of applications. One application is science data collection. In fields like earth and atmospheric science, researchers are seeking to use UAVs to augment their current portfolio of platforms and increase their accessibility to geographic areas of interest. By increasing the number of data collection platforms, UAVs will significantly improve system robustness and allow for more sophisticated studies. Scientists would like the ability to deploy an available fleet of UAVs to traverse a desired flight path and collect sensor data without needing to understand the complex low-level controls required to describe and coordinate such a mission. A natural interaction interface for a Ground Control System (GCS) using gesture recognition is developed to allow non-expert users (e.g., scientists) to define a complex flight path for a UAV using intuitive hand gesture inputs from the constructed gesture library. The GCS calculates the combined trajectory online, verifies the trajectory with the user, and sends it to the UAV controller to be flown.
