What is the allowed way to get images? And how to get them for both drones?

Hello,

I would like to know what is the allowed way to get images 2 and 3, please (I mean the exact API call). Right now, I am doing this (I have modified the .json file so drone_2 also has a fpv_cam with the same settings as drone_1):

im1 = airsim_client.simGetImage(camera_name="fpv_cam", image_type=0, vehicle_name='drone_1')
im2 = airsim_client.simGetImage(camera_name="fpv_cam", image_type=0, vehicle_name='drone_2')

This doesn't work by the way. I get the same image for both vehicles. How can I get them for each drone?

unfortunately, airsim doesn't allow same camera names. use fpv_cam_2, and this should work.
using either simgetimage or simgetimages is fine.
we don't expect people to be looking at what drone_2 is seeing. we expect them to get the pose of drone_2 directly

Yes, images from drone_2 are only for training purpose in my case. I'll try this, thanks

I think simGetImages is faster than simGetImage. You can test with this script https://github.com/microsoft/AirSim-NeurIPS2019-Drone-Racing/blob/master/baselines/baseline_racer_image_benchmarker.py

Oh yes now I see why you were preoccupied about passing more than one image per drone. Even passing 1 image per drone with simGetImages is extremely slow on my laptop, maybe 4 FPS. What about using a much lower resolution?

This solved this question by the way, so I close this issue, I will be opening another one for simGetImages() huge overhead.
