> The Mail Rail scan is comprised of more than 11 billion points, consuming over a terabyte of storage. That's about 90 bytes per point. Seems a lot.

  When I devised my format for laser scanning, I used X, Y, Z, R, G, B where X, Y, and Z are 4 bytes. RGB was 1 byte each, total of 3 bytes. That's 15 bytes. So.... I'm 600% more optimized than Faro? I think someone's off on their numbers.

    Is it the difference between raw data and processed? The scan could have things like [I'm guessing] corrected baseline direction of the laserbeam (3-axes: theta, phi, psi??), time of pulse initiation in ns(?), time of pulse reception, colourific data, CRC. Then you process that to create the point cloud?

      I made mine using a line laser and a webcam. Its slow, but I can scan decently well, and in color. Of course, the more lasers and cameras, the faster I can scan.

        Do you have more details somewhere about how you made it?
