  • ALTITUDE SMOOTHING
    Publication number: 20240094026
    Abstract: A system and method including receiving a digital representation of a road that includes one or more lane representations; defining a factor graph including variable nodes and constraint nodes that encode lane boundary constraints for the lane map; translating the factor graph into a nonlinear optimization problem for altitudes of the lane map; generating a solution to the optimization problem; and generating a corrected lane map with an optimized altitude for the road based on the generated solution.
    Type: Application
    Filed: April 28, 2023
    Publication date: March 21, 2024
    Inventors: Grady D. WILLIAMS, Phillip James HAEUSLER
  • METHOD AND SYSTEM FOR TOPOLOGY DETECTION
    Publication number: 20240071101
    Abstract: A system and method including receiving an image of a first lane of a road, the image being captured by a first sensor; defining the first lane as a set of N ordered points; representing the first lane by a combination of N ordered points and a predefined number of types of lane components, C; generating images, each image representing one of the types of lane components; and combining the generated images to generate a topology representation for the first lane.
