Payload systems and tracking algorithms for photogrammetric measurement of parachute shape

摘要

Parachute systems play a critical role in many science and military missions. Currently, NASA and the U.S. Army air delivery systems programs are evaluating measurement technologies to support experimental and qualification testing of new and modified parachute concepts. Experiments to validate the concept of parachute shape measurement have been conducted in a controlled, indoor environment using both fixed and payload cameras. The paper will provide further detail on the rationale for the experiments, the design of the payload systems, the indoor and outdoor testing, and the subsequent data analysis to track and visualise the shape of the parachute.
