[JdeRobot] Depth image

[JoseMaria Cañas Plaza]

Hi Rebeca,

yes, using only the first byte (R) you are getting the summary of the
depth (255 levels up to MAX_LENGTH). To get the full depth information
better use the other two bytes (G and B) according to the encoding
described in [1].

Cheers,

JoseMaria
