The Stereo-Vision-Experiment Review Tool team used the stereo image data provided by the SPHERES micro satellites project to build an experiment review iPad app. NASA’s SPHERES program – Synchronized Position Hold, Engage, Reorient, Experimental Satellites -- consists of three free flying vehicles inside the International Space Station identifiable by their shell colors of Red, Blue, and Orange. Initially the SPHERES were designed for testing of control theory algorithms. The Satellites are about the size and mass of a bowling ball and use cold gas thrusters (CO2) to propel the vehicles around a fixed experimental volume.
Data for this solution comes from NASA's SPHERES program, which uses ultrasound beacons as a metrology system to identify its position in conjunction with accelerometers, and gyroscopes. The tool created by the team allows scientists to easily review YouTube videos captured from the space station experiments by facilitating browsing and visualizations. Users can bookmark and annotate significant areas of the timeline and browse adjacent time-slices interactively. The team created an API that links the annotated video feed and specific frame to visualizations.
