Sentera NDVI imagery

 Do you/can you process imagery from a Sentera NDVI camera? I'm not fully sure how it works but I guess it's the Sentera's NIR images plus the Phantom 3 Adv RGB images combined? Any gotchas?

 

Thanks

Thanks Matt, I know about AgVault, but can Maps Made Easy process Sentera imagery?

Ive never tried it, Ive only ever used agvault and I've never processed a full orthomosaic with it. Would be interesting

Sentera imagery is frequently uploaded to our system and the results are highly variable. 

Maps Made Easy can process any tagged imagery provided that it is in focus and not smeared. Rolling shutter cameras often exhibit issues with stitching especially if the rolling shutter is a low frame rate one. Global shutter imagery should have no trouble.

Thanks for the comments Zane. The Sentera has a global shutter for the NIR/RE band so that should not be an issue, however it's interesting that common RGB cameras (eg DJI Phantom 3/4, Inspire 1 etc as used for normal mapping) are the ones that have rolling shutters! Presumably image format is not an issue with the Sentera and can be used straight from the camera (together with the DJI RGB images) in MME?

Maps Made Easy only accepts JPG images. Generally, global shutters are only available on lower resolution sensors unless you want to spend LOTS of money. Most of the high resolution global shutter options are industrial or machine vision cameras.

Sentera with DJI should generally be no problem for MME then.

Thanks Zane for the comments & clarifications :-)
