I am working on EKF-MonoSlam (Davson) method for the mere input as a webcam, (it works "fine" if we calibrate and use reasonable sigmas) , and I am trying to add the odometry of some dataset (as rosbag) as in the reference (https://github.com/rrg-polito/mono-slam)
so the odometry (estimated pose) is added so $V_k$ is to make $r_k$ right and so $\Omega_k$ (I know I could use velocity , but I need this working first) , that is supposed to make the camera in the right track as additional measurement, but what happens is:
- the camera refuse many matches (as the projection of it is wrong),and soon drift and get lost.
Why is that? and How to fix it?
the dataset site says that odometry data is not calibrated , so I am thinking that it maybe need some scale parameters to make the image estimate of pose match with odometry estimates, if so, how to find that scale
any help or reference ,would be appreciated ,Thank you
now I am using velocity of odometry as input and it's better (still there's errors), any link to code or explanation of adding odometrey (as control not measurement) to compare how it goes would be appreciated , this is really a headache in c++...
