I am trying to create synthetic data with unreal engine. I want to fly a drone(with airsim or anything else) and capture IR images. as its for teaching a neural network, I need a real good IR vision images. I mean just a texture with red color and orange color respecting the corners(like another tutorials in the net) is not as good as I want. airsim it self has a IR vision but its something like grayscale and its not good as it should be. can you please Help me doing this :)?

no different UE4 or UE5 or even unity! I just need the simulation (even in paint :D)

I was thinking about setting a variable Temperature for every single object in my scene and using this to convert the RGB to IR but idk it is good or not. also if you know some material or object available in the market that will capture IR vision images it will be nice if you tell me about it.

its my unreal project

IR vision image(no matter left one or right one)

  • any idea can be useful :) i have to do it asap so i need your help – Reza shahriari Aug 10 '23 at 06:38
  • You're looking for a post effect. If you search on google there'll be a bunch of tutorials on creating one - i'm sure you could also find something on the marketplace. You could probably just have the effect always active for your purposes. – George Aug 10 '23 at 11:04
  • Thanks @George I have searched both google and marketplace but I have found nothing yet... i am steal searching to find some useful thing:) – Reza shahriari Aug 10 '23 at 13:00
  • I think it depends on what are you trying to achieve. If you are trying to classify different objects based on their heat signatures, then it is best to create a realistic heat distribution per object and a post processing shader. But if you are trying to detect heat zones, like above a certain threshold, I think you can get away with just using a post processing shader that only looks like a real IR output. Let us know how it goes. – esgnn Aug 10 '23 at 21:29
  • @esgnn yea i want the second one. i just decided to make temperature for every single object and then convert this temperature to IR. thanks for the help – Reza shahriari Aug 11 '23 at 08:16

no chance ... unreal is a game engine... use something else for simulating the real world and creating synthetic data and also airsim... its not even supported by Microsoft why you are using it!?

  • The question is simply how can the op simulate IR vision in unreal. Nowhere do they say anything about simulating the real world. Unreal is more than capable of IR capture... – George Aug 10 '23 at 11:02
