TL;DR: In this article, the authors present approaches and design constraints for a video guidance system for autonomous rendezvous and docking of spacecraft in close-in operations, where operation with multiple target spacecraft is required.
Abstract: A number of future space missions will require autonomous rendezvous and docking of spacecraft. Recent work in video guidance shows that a video approach has great promise for solving problems in close-in operations, especially where operation with multiple target spacecraft is required. A video guidance system can be built with existing processor and sensor technology. This paper presents approaches and design constraints for such a system.

TL;DR: A system-level approach is proposed that incorporates this technique into a complete paradigm for real-time image-based guidance in order to provide a physician with continuously-updated navigational and guidance information.
Abstract: Previous research has indicated that use of guidance systems during endoscopy can improve the performance
and decrease the skill variation of physicians. Current guidance systems, however, rely on
computationally intensive registration techniques or costly and error-prone electromagnetic (E/M)
registration techniques, neither of which fit seamlessly into the clinical workflow. We have previously
proposed a real-time image-based registration technique that addresses both of these problems. We
now propose a system-level approach that incorporates this technique into a complete paradigm for
real-time image-based guidance in order to provide a physician with continuously-updated navigational
and guidance information. At the core of the system is a novel strategy for guidance of endoscopy. Additional
elements such as global surface rendering, local cross-sectional views, and pertinent distances
are also incorporated into the system to provide additional utility to the physician. Phantom results
were generated using bronchoscopy performed on a rapid prototype model of a human tracheobronchial
airway tree. The system has also been tested in ongoing live human tests. Thus far, ten such tests,
focused on bronchoscopic intervention of pulmonary patients, have been run successfully.

TL;DR: In this paper, a method for guiding an aircraft toward a stopping position within an aircraft stand of an airport comprises using a visual docking guidance system (VDGS) associated with the aircraft stand for displaying first instructions for guiding the aircraft toward the stopping position.
Abstract: A method for guiding an aircraft toward a stopping position within an aircraft stand of an airport comprises using a visual docking guidance system (VDGS) associated with the aircraft stand for displaying first instructions for guiding the aircraft toward the stopping position. The first instructions are based on an initial determination of the aircraft-type and on first sensed positional information of the aircraft. Aircraft-type data that is stored in a radio frequency identification (RFID) tag carried by the aircraft is then read. Using the VDGS, second instructions are displayed for guiding the aircraft toward the stopping position based on the aircraft-type data and based on second sensed positional information of the aircraft.
