Before I talk about the shoot, I want to show you a sample of the data. It's really very simple. The following are three points I pulled arbitrarily from the data of Thom Yorke singing. They're in the file 2067.csv, which is the 1,067th frame in the video. Because each second is 30 frames and the first frame is 1001.csv, these data points can be seen at around 0:36 in the video. You can find this datafile on the Google Code site, along with the other frames:
70.05, 162.48, -79.32, 122 70.23, 165.26, -78.82, 112 70.46, 168.00, -77.55, 95
The data are in the format
x, y, z, intensity. All of the data we captured was eventually translated into this format.
The x, y, z values are relative distance measurements. The GeoVideo system, like the Lidar, has a 0, 0, 0 point upon which it bases all other points. What 70.46 means, therefore, is that the point is 70.46 units along the x-axis away from the 0 point. You can scale these numbers however you want. The intensity range is from 0 (0% white) to 256 (100% white).
You'll find 2,000 frames' worth of Thom singing on the Google Code site, comprising just over a minute from the video. The audio is available as well. We also included two static landscapes' worth of data: the city and the cul-de-sac. They are in the HoC_DataApplications_v1.0.zip archive that includes the viewer program.
The data you see on the site is in the same format as the data we delivered to the post-processing studio, with one minor difference. The studio wanted RGB ...
