Lego Panorama

Comments Off

I’ve discussed panorama robots in the past, and here is a new creation. James Catan has created several Lego robots to do timelapse and and pan/tilt pictures. One of them were recently presented in Gadget Review, and shows holding a Canon Rebel XT with a kit lens. So not quite 5D, 200mm f2.8 as with Jeffrey Martin’s rig. Yet still a good and simple setup.

Another interesting pan & tilt product comes from Sparkfun. It is a robot arm, consisting of servos and and a claw. It will definitely not hold a SLR, but possibly some smaller pocket cameras or phones. As far as I understand, the complete robot arm comes in several parts which you’ll have to add to your order separately.

Strahov Library 40 Gigapixels

Comments Off

Jeffrey Martin, founder of 360Cites, recently released a 40 GP indoor panorama of the Strahov Library in Prague. It claims to be the world’s largest indoor panorama. It consists of 2947 shots, which combine to the 280,000 x 140,000 pixels, and 280 GB image.

You can view it here, but be aware that the Flash application and pictures can take quite some time to load. I also have the Flash crash several times.

The TC article mentions the he used a Canon 550D and a 200mm lens. It is also covered by Wired, and from their picture of the setup, it seems to be a Canon EF 70-200mm f/2.8 L USM. The Canon 550D is a 18 MP camera, which means 2947 input images gives a total of 53 GP raw data. Furthermore, he uses RAW files, at around 20 – 25 MB echo, so that would take up 59 to 73 GB on the card. (Thus, the 280 GB number above seems a bit strange).

Furthermore, it intersecting to note hat he uses the GigaPanBot by T. Emrich from Germany. I wrote about his project in November last year, and got the impression it was more of a hobby project. It seems he has made a nice niche business for himself.

In the Wired article, they mention that the camera does not always get focus, so Jeffrey has to jump up, pause the robot, fix the focus, and continue. It also says that on the first day, he managed to finish about 20% of the job before the library closed at 5 pm. It doesn’t say how long it took to complete, but at that rate it would take a week! After that, it took 111 hours to stitch everything together, and about 10 hours of work to fix misaligned images.
