velocity in KF states

[lucianzhong]

Hi,
thanks for this great work. I am tring to get the velocity of obstacles
Print out the KF states, the last three is zero as well which stands for the vx,vy,vz.
self.kf.x: [[40.33045757]
[ 0.72194955]
[-0.91660528]
[ 1.48425448]
[ 2.16024897]
[ 0.89416712]
[ 1.75878836]
[ 0. ]
[ 0. ]
[ 0. ]]

i have the same problem,do you get the solution?

[lucianzhong]

not yet. How about you?

@lucianzhong @Jason-Du111 If this is the first frame or the first frame of an object, it will have zero velocity due to initialization. Could you please check if all the objects have zero velocities, or only a few?
