Art Meets Science

Preserving Through Documentation

For the next several weeks we will be documenting and processing the data gathered from the Rio Vista Farm. We are cleaning the laser scan data acquired in the field last week with the high definition 3D scanner of the 43 stations. This is a multi-step process since we have to get all of the different pieces and programs to speak to each other in the proper formats.

We had to download each station’s point cloud scans and use a program, Cyclone, to clean the files. We also had to convert the panorama images from NEF to TIFF into JPEG, using Capture NX-D and PTGui. After rearranging the panoramas and cleaning the 3D scan data, we began the photometry process. This is essentially overlaying the colored image with the pixel image, which creates the 3D site image. Once we register each station into a single database we will be able to create a fly through of the editors site so that everyone can get a glimpse of the Rio Vista Farm.

 

The points come together to form the 3D scan

This is an example one station, for each station we took 30 images at different exposures. The program, Capture XN-D, selects the best exposure and aligns the images together through control points and in order to create the panorama. This colored image is what we would use to combine with the point cloud data.
