Voxl2 camera RAW

[robertociuch]

Hi everyone,

is there a way to take some raw snapshot from the HiRes camera (IMX412 w microcoax wires)?
I see that the file created by "voxl-send-command hires_large_color snapshot" is pretty small (less then 800KB)
The preview on the voxl portal seems even better compared to the jpg image

thank you in advance!

Hi all, I work with Roberto, adding here the voxl-camera-server.conf file we are currently using.

{
	"version":	0.1,
	"fsync_en":	true,
	"fsync_gpio":	109,
	"cameras":	[{

}

We are using the snapshots for one of our projects and we would need to have the most detailed image possible to be processed with an external algo.
Thanks
