Hello Guys,
First want to take a moment and appreciate this amazing work. The calibration process is very precisely explained in the paper and I am also thinking to use the same methods for my work on sensor fusion. I will be calibrating LIDAR and Radar with this repo. Since my application is a bit tricky and we have to use the measurements that are probably 80 meters away from the sensors.

Is it better to also calibrate the sensors by placing the calibration tool a bit far away from the sensors in my case? Let's say 25 meters. If so, I have to change the dimensions of the styrofoam. I was also thinking to increase the thickness of the styrofoam, as we are doing the experiments in an open environment. In windy conditions, thicker styrofoam might be more stable. Let's say 12 cms. Does the thickness of styrofoam affect the radar points interacting with the reflector? also, Can you also tell what was the type of styrofoam you used? Was it probably EPS 040?

I don't think 80 meters would be problematic as long as the detectors still work. It will probably require some tuning of the detector parameters and the camera should have sufficient resolution.

The styrofoam and windy conditions are indeed problematic. The calibration board is very lightweight and easily blown away. Yet, having a person holding the board may affect the radar detections. I don't know if thicker styrofoam would add enough weight to stabilize it.

I don't expect the thicker styrofoam to affect the radar points, but I haven't tested this.

Unfortunately, I don't know what type of styrofoam was used exactly.
