Spatial sensing and measurement on mobile devices

APIs from RealityCap give iOS apps the ability to sense their surroundings in three dimensions. This patent-pending sensor fusion technology combines computer vision and inertial data to give your apps accurate 6DOF device motion and a 3D point cloud of the environment. RealityCap software runs on 2011 (A5-based) and newer devices in real time, with no additional hardware or markers. Results are accurate over both short and long distances, and come with absolute scale in meters.

I’ve previously covered other apps that are coming to market to help DIYers and professionals to quickly size rooms. This is slightly different; in that their is no external tool. You take a photo, that gets sent to a web service that does the calculations to work out the length of different objects in the photo. Very smart stuff.

Beautiful long exposure photographs by NASA astronaut Don Pettit

Last month we shared a long exposure photograph by NASA astronaut Don Pettit that showed star trails and city trails in the same frame. Turns out the photo was just one of many long exposure images shot by Pettit so far during Expedition 31. The photograph above shows star trails, an aurora, and flashes of lightning splattered all across the surface of the Earth. (via Incredible Long Exposure Photographs Shot from Orbit)

Eiffel Tower in Paris gets struck by lightning

(via Sacrebleu!) A lightning strike gives a vivid backdrop to the iconic Eiffel Tower, while the Paris landmark is illuminated in vibrant blue lights. Amateur photographer Bertrand Kulik captured the shot which will appear in an exhibition titled “Lumieres celestes, lumieres des hommes”, in Issy L’eveque, Burgundy. It was taken 21:02 GMT, 28 July 2008 during a storm in the French capital.
