Depth Filtering Level (Micasense RedEdge MX)?
« on: June 20, 2019, 08:43:45 PM »
Hello everybody!

I am working on a project involving monitoring grain sorghum height throughout the early growing stages. To do this, I captured a DEM (bare soil, before any growth) and will then capture data when the sorghum is growing to generate a DSM; the DSM will be subtracted from the DEM to get vegetation height.

My question is this: What depth filtering should I use? I need as much detail as possible since my plants are really small. As I understand it, the higher the level of depth filtering, the less detail will be shown in the DEM/DSM.

Here are the parameters/equipment I am currently working with:

DJI Matrice 200
Camera: Micasense RedEdge MX
Flight altitude: 30m (I desire to eventually take this down to an altitude of 15-20 m)
Alighment quality: High
Key point limit: 40,000
Tie point limit: 4,000
Dense point cloud accuracy: High
Depth Filtering: Mild

Any help would be appreciated! Thanks everyone!
