Jello effect in Orthomosaic generated for Micasense Altum
« on: August 29, 2023, 12:59:56 PM »
Getting a wavy effect in multiple regions of orthomosaic processed using Agisoft Metashape 1.8.5. Updating too latest version also did'nt help either. If anyone has solution related to this, please reply.

Image Format : TIFF Unsigned 16 Bit

Screenshot of the wavy pattern is also attached to get a clearer understanding of problem.

this is all from memory so some of the names/places of things might be a bit off!

right click on the affected part of the orthomosaic and select 'open image' (i think this was available in 1.8.5). then you will see which image was used to generate this part of the orthomosaic. you will probably/hopefully find that for whatever reason it didn't choose the best image for that part, i.e. too far away or at an oblique angle.

to fix it, draw a polygon around the affected area (turning on seamlines can help to see the extent of the area covered by this suboptimal image) and right click on the polygon and choose assign images. then select the image that should have been used. once happy, right click on the orthomosaic in the chunk explorer (i forgot what it's called exactly) and choose regenerate to apply your changes and blend the images together nicely.

if there is no better image to choose from in the 'assign images' window, then either you didn't get a good image of that area, or some of your images are misaligned.
