Pts file content order

[knelson026]

When exporting from recap to a .pts file and opening it in a text editor, what format is each line in? It appears to start with x, y, and z, but I can't seem to figure out what the next 4 values are.

PTS format is:

<X> <Y> <Z> <Reflectance> <Red> <Green> <Blue>

<Reflectance> is a normalized measurement of the laser return on the measured surface, in range 0 (no return) to 1 ('full' or bright return).

Red/Green/Blue are the color of the point in 0-255 (8-bits).  For point clouds with no color, these columns will represent a grayscale version of the reflectance.

There's not a firm standard for PTS but this link is somewhat helpful (notice the slightly different intensity scale though):
