연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

The method according to claim 1 wherein providing a video overlay comprises: detecting a position of the aircraft to be refueled; andproviding a detection video overlay on the display indicating a relative position of the aircraft to be refueled with respect to the refueling environment. 3. The method according to claim 2 wherein providing a video overlay further comprises: removing the detection video overlay upon identifying the type of aircraft to be refueled; andproviding an identification video overlay on the display indicating the type of aircraft and a relative position of the aircraft with respect to the refueling environment. 4. The method according to claim 1 wherein providing a video overlay comprises: detecting that the position of the aircraft to be refueled is within a defined refueling area;providing a reticule overlay on the display indicating an impact point of the refueling boom; andadjusting a position of the reticule overlay based on boom operator maneuvering of the boom. 5. The method according to claim 4 further comprising changing a color of at least one of the first and second receptacle overlay and the reticule overlay when the boom operator maneuvers an intersection of the reticule overlay to be within the first and second receptacle overlays, indicating the boom is aligned with the refueling receptacle. 6. The method according to claim 1 further comprising: monitoring at least one of a closure rate and a distance between the aircraft to be refueled and the tanker aircraft; andchanging at least one feature of the at least one video overlay indicative of the positional relationship when at least one of the closure rate exceeds a predefined rate and the distance between the aircraft to be refueled and the boom of the tanker aircraft becomes less than a predefined distance. 7. The method according to claim 1 further comprising providing at least one indicator for viewing on the display by the refueling boom operator, the indicator illustrating an amount of mechanical stress in a physical engagement between the boom and the aircraft to be refueled as providing by at least one strain sensor attached to the boom. 8. The method according to claim 7 wherein providing at least one indicator comprises providing indicators indicating the amount of mechanical stress in both azimuth and elevation. 9. An aerial refueling situational awareness system comprising: a camera operable to provide a video image of an aircraft in a refueling area, the refueling area including a distal end of a refueling boom therein;a vision processing system communicatively coupled to said camera; andan operator display communicatively coupled to said vision processing system, said operator display configured to present images of the refueling environment to a boom operator, said vision processing system programmed to: automatically identify a type of aircraft when an aircraft to be refueled enters the refueling environment;generate at least one video overlay over the video image of the aircraft provided by the camera such that the at least one video overlay at least substantially surrounds the video image of the aircraft, wherein the at least one video overlay is based on the identification of the type of aircraft, the at least one video overlay configured to provide situational awareness to the boom operator viewing the refueling area on said operator display and indicate a relationship between the aircraft to be refueled and a tanker aircraft, the at least one video overlay including at least one guidance cue configured to assist in aligning an aerial refueling boom coupled to the tanker aircraft with respect to a receptacle coupled to the aircraft to be refueled such that the aerial refueling boom is coupleable to the receptacle, wherein the at least one video overlay is based on a position of the refueling boom as sensed by the camera and relayed to the vision processing system; anddetermine at least one of a number of fuel pumps and a fuel flow rate to be used by the aerial refueling boom based at least in part on the type of aircraft to be refueled. 10.
