Abstract: A method of visual odometry for a non-transitory computer readable storage medium storing one or more programs is disclosed. The one or more programs comprise instructions, which when executed by a computing device, causes the computing device to perform the following steps comprising: performing data alignment; obtaining data from sensors; based on the data from the sensors, performing machine learning in a visual odometry model; generating a prediction of static optical flow; generating motion parameters; and training the visual odometry model by using at least one of the prediction of static optical flow and the motion parameters.

Abstract: A method of generating a ground truth dataset for motion planning of a vehicle is disclosed. The method includes: obtaining undistorted LiDAR scans; identifying, for a pair of undistorted LiDAR scans, points belonging to a static object in an environment; aligning the close points based on pose estimates; and transforming a reference scan that is close in time to a target undistorted LiDAR scan so as to align the reference scan with the target undistorted LiDAR scan.
