Evalutation Scripts, RMSE 0% on all sequences, trajectory file consists only of small number of frames

[ashishkumar822]

Hi, I have two issues with the code base.

1. I have got to compare accuracy of ICE-BA with some different front-end. But I could not find any evaluation script for computing ATE.
2. I went through the code and found that back-end consists of RMSE calculations. However when I run it, I always get zero LBA and GBA error.

I get the following output:

Kindly provide solution as soon as possible as we need to meet a near deadline.

Thank you

Hi @ashishkumar822 ,
if it is not too late already, you can try using evo https://github.com/MichaelGrupp/evo for the calculation of RMSE
