Support for velocity and covariance #491
Description
Hi @MichaelGrupp, thanks for the great work, love evo and use it fairly often.
Is your feature request related to a problem? Please describe.
One of the issues I often face is that I want to look at more than just poses, namely estimated velocity and uncertainty bounds.
Describe the solution you'd like
- First would be plotting support for these data if they exist.
- A new text file format or an extension to the TUM format which includes velocities and uncertainties.
Describe alternatives you've considered
🤷🏼♂️
Additional context
I can imagine that plotting multiple uncertainty bounds can get messy very quickly. Already, if your reference trajectory has uncertainty bounds, plotting two trajectories would create 6 curves and be hard to read. Maybe we would need an easy way to select which uncertainties are plotted?
