Virtual Drone

A fly through of a 3D Model of a Stone Building derived through Photogrammetry showing the model overall and then getting closer to the surface to show the richness of organic detail captured.

A few snapshots from a 3D point cloud / 3D scan of this structure- in support of a rendering by a third party. (Snapshots are screen grabs from Autodesk RECAP)

Snapshots of a 3D point cloud

Its admittedly pretty fun to fly around a house once you have the point cloud made, taking “pictures” that you couldn’t have snapped when you were actually on site without the use of a jetpack!

Spending a lot of time seeing how different photogrammetric systems and point cloud software packages speak to one another. sometimes the interface is elegant, sometime not so much…

I have been neglecting updates on my website, even though I’ve been doing some interesting work!

2016 has been extremely busy with large projects at the Biltmore in Asheville, NC and in San Antonio, TX (above). I’ve also had a chance to do some design work for two restaurant installations here in Virginia – “The Store” and “Chicano Boy”.

Plus I had a nice show of photographs of Portsmouth Island, NC that has been hanging in Ocracoke all summer.

That’s all for now – just wanted to post something 😉

Last summer I was hired by Frazier Associates in Staunton to prepare some as found documentation of the Bob White Covered Bridge in Patrick County, Virginia for preservation work to be conducted through VDOT. I learned yesterday that bridge was washed away in flash flooding! This is horrible to learn; now only seven covered bridges remain statewide, I believe.

I am therefore VERY glad to have a couple hundred photos of the structure suitable for photogrammetric rectification. I did prepare some simple drawings and orthophotography, small versions of which I’ll share here. I’ll also share some video snap shots of the point cloud I created.

I hope to get in touch with anyone who might be interested in rebuilding. If you stumble upon this page and share my interest please contact me!

Aerial Photography > Dense Point Clouds

Since 2009 I’ve done a fair amount of work with aerial photography, all the while continuing to explore architectural photography and photogrammetry while on the ground. I’ve tried in the past with some success to merge the two things but have found the results to be lacking something. That something, I think, is the hyper dense point cloud – and now I have it pretty much figured out.

Below are tow animated GIF images showing first the point cloud describing our local hospital (which I was contracted to cover with aerial photographs a few years back) and the second is a textured 3-D model of the scan.

Its so amazing to think that the flight over this structure can be reconstructed virtually a few years later with even more options to “fly around”…
