I am trying to Analyse the ego vehicles velocity at different instants in time. For a particular scene, I can get the ego_pose for different sample_data for a particular sensor, and get the instantaneous velocity by (distance travelled by time interval between the two timestamps. However for the first_sample token, I will nto be able to figure out the initial position and the initial timestamp. Is it alright to assume the vehicle stars from (0, 0) and initial time being 0 ?
thanks
