General / Re: Colorize Dense Cloud from multispectral camera

Hello,

I was tracking this thread and the Agisoft tutorial on reflectance calibration of the Micasense Red-Edge Camera (have reviewed the Micasense tutorials and git repository as well).

Has the Agisoft team published a technical tutorial on how the DLS 2 sensor is used for calibration within MetaShape?   The Micasense documentation that I've found is sparse, only a bit on the older DLS 1 sensor.

Thanks in advance and I apologize if this information has already been provided.

Hi Alexey/All,

I apologize up front if this has been answered elsewhere, but can you point me to the algorithm/papers that describe the conversion  between the australis calibration coefficients and the defaults shown in the Photoscan GUI?

For the radial terms, It appears that the conversion is roughly (but certainly not exact):

k1_photoscan = f^2 * k1_australis
k2_photoscan = f^4 * k2_australis
...

where f is the focal length.

Any insight greatly appreciated.

Thanks!
