Improvement of multicopter detection using an infrastructure camera

THERE has been increased worldwide interest in aerialrobots in recent years, and research toward a variety of applications is underway. However, aerial robots are difficult to control, frequently leading to accidents. In the case of indoor aerial robots, it is furthermore difficult to ensure that operators retain line-of-sight. Therefore, extensive research has been conducted on robots capable of autonomous flight, for example, in regard to hovering, movement to a specified destination, obstacle avoidance during flight, and object detection. During autonomous robot flight, measurement of unit position is extremely important. The present research assumes indoor flight, so GPS-based systems cannot be used.
