Mooncast Simulation in HD

While working on our on-board video processing pipeline we reached a point where we needed a test video that would be representative of a mooncast for the Google Lunar X PRIZE. Using a regular video is not the best solution here because a mooncast has a different motion and color profile and these parameters can have great influence on the efficiency of the compression algorithms.
Therefore, we took some Apollo 17 surface photos from EVA 2 Station 4 (Shorty crater) and created a simulated mooncast consisting of a 360 degree pan. To make it a bit more entertaining we added some original voice recordings from the EVA.

The simulation uses stereographic projection, which allows panning and zooming in all directions. The vertical field of view is 60 degrees. The flickering of the small stones is an artifact of the projection algorithm and not the video compression. We will have to improve that.

Watch in HD

So what do you think? Is the quality good enough for a GLXP mooncast? Or is it too bad? Is the panning too slow or too fast? Leave your comments!
