Old Photosynth part 2

Photosynth Part 2

Since writing the old site, Photosynth.net has been discontinued.

However, whilst updating this I found out that Microsoft has reused it.

It is a phenomenal piece of software which had me absolutely amazed when I first used it. It was very easy to use, and just did what it set out to do.

It is good for small panoramas such as Vancouver Docks below. It is amazing when you just chuck almost 500 photos at it and it resolves most of them into the view from Vancouver's Lookout Tower. Also below. I think it would have been a full 360 degree view if I had done it all at the same time. I had already used some of the images in Part A as a test, so they were not included in the full run. As to be expected, it does take a long time to upload and process so many images, but I think the result is worth it.

The software can be downloaded from the Photosynth web site. {This now rediercts, very slowly, to a developer blog. Search for Photosynth to see the news} You do not need to have Photosynth installed to view either the embedded images or the web site. You do however need to have Silverlight installed.

My Photosynth projects are below; {Well they are no longer there. They were hosted on Photosynth.net, which is now clossed}

They open with the Silverlight 3D view. The button with the two rectangles has alternative views, including a 2D view showing all of the constituent photos. After exploring the different views, you could play the slideshow to be wowed again.

The Vancouver Lookout is a high level observation tower near Canada Place in downtown Vancouver. The Lookout tower is on top of the Harbour Centre office building. This is the view on a sunny summers day in 2010. This is made up of over 400 photos.

A day out at the International Festival of the Sea held in Portsmouth in 2005.

On the way north on MS Richard With, a Hurtigruten ship. Day 2 includes a visit to Alesund. This is the view from the docks and a quick trip into the town centre.

Birthplace of the Industrial Revolution. Ironbridge was the first arch bridge in the world to be made of cast iron. Construction began in 1779 and the bridge opened on New Year's Day 1781.

Views from the Shard over London at the end of August 2014.

I went to the Shard for the views, but also with the express intent of creating a 360deg Photosynth panorama. I am pleased with the result. I noticed that if the jump in image magnification is too large the software does not make the connection. I stared with a 300mm lens (450mm in 35mm equivalent) and did a full circuit of the viewing level, the 69th floor. Then I changed lens to a 35mm lens (52mm in 35mm equivalent) for the backdrop. I finished with a 15mm lens (22mm in 35mm equivalent) for the interior. I think if I had also done a complete circuit with a 100mm lens the software would have been more able to do the pattern recognition required to stitch the synth together. Despite some of the close ups not meshing with the background, it was a brilliant day out.

Another example of Photosynth as a panorama including the Shard; by 'nutterguy'.

From the same set of photos I have created the following panoramas;-

  • HMS Belfast
  • Tower Bridge

 

2018 Note. A few years ago, in my BIM Consultant role, at a BIM conference, I was speaking to the founder of a company which works with drones and photogrammetry. It is a very close community of developers working in the field of stitching photos together. Photosynth and the work they were and are doing have a lot of similarities.
