Abstract
In recent years, a wide variety of robots that can be used in the human living environment has been studied. Then, in such environment, the robots need to find where they are if they support human. Therefore the purpose of this study is to suggest a human tracking method of a multi-rotor craft with the HOG algorithm using the image of a monocular camera installed on the multi-rotor craft. This study showed that multi-rotor craft can performed human tracking by the method proposed in this study.
