Approximately how much marking data do I need to collect?

[gokcesena]

Thanks so much for the work. I hve some questions:
Approximately how much marking data do I need to collect?
After calibrating once on the fixed system, do I need to repeat the same processes for each environment, or is calibrating only once sufficient?
What should be the average RMSE value?
Thank you in advance.

The more data you have for calibration the better it is. But you can try with min 20 first.

For fixed system (fixed camera and fixed lidar), you only have to calibrate once.

I can't say much on the average RMSE value, as it depends on your system and calibration data.
