Hello,
I need to paint over 200 targets for our upcoming project and I need some advice on what would be the best option to paint.
I’ve done some tests and it’s really hard to see from the intensity (or intensity gradient) view at 200ft AGL & 5 m/s speed.
I’m wondering if there’s a certain pattern and/or type of paint that would be more visible?
How we’ve done our paint was black and white checkerboard pattern.
This is how it looks from 100ft AGL at 2 m/s speed (low pass)
This is how it looks from 200ft AGL at 5 m/s speed (normal operating altitude)
This is the paint we used
How we painted
We need the paint to show up at 200ft agl 5 m/s speed as constantly doing low passes will really delay our timeframe.
Your advice will be greatly appreciated!

we use something like this painted in a 4" thick chevron, and we get great visibility- we usually fly around 160’-200’ AGL.

Did you find a solution to this?
I’m also having trouble identifying the centre of GCP in R3 Pro data at 200’ / 5ms.
I have tried paint
- line marking paint
- 24" black white canvas panels (from bullseye)
- honeycomb reflective backed boards.
The canvas panels don’t show at all, but they are designed for photogrammetry.
Paint also doesn’t show well at that altitude but I guess it depends on the paint used?
Honeycomb reflective backed panels show up great but I cannot make out the centre.
My next two options are:
I’m coming to the conclusion that it’s not really the colour, its the reflectiveness of the material.
The hunt continues.
