  • Lidar localization using optical flow
    Patent number: 12436281
    Abstract: A method for determining a lidar sensor pose with respect to a predefined map image, comprising acquiring a lidar height map; determining an optical flow field, which relates the lidar height map and the map image; and computing a maximum-likelihood/ML estimate of the lidar sensor pose on the basis of the determined optical flow field. The optical flow field may optionally be determined by a regression model, which additionally produces an associated variability tensor to be used in the ML estimation. In particular, the optical flow field may be determined by a trained neural network.
