AI Technical Summary

Technical Problem

Existing methods for generating vehicle maps, such as Graph-SLAM, are computationally intensive and require high power due to complex landmark considerations, limiting their effectiveness in vehicles with limited computing resources.

Method used

A method for generating vehicle maps by segmenting poses into subsets based on Euclidean distances and yaw angles, using hyperedges to connect poses within the same driving route, allowing for efficient map display updates and reduced data transmission.

Benefits of technology

This approach enables accurate and efficient map display generation with reduced computational requirements, allowing for precise localization and minimal data transfer, while minimizing landmark considerations.

Abstract

To provide an improved method for generating a map display about vehicles.SOLUTION: A method includes the steps of: receiving vehicle sensor data; and determining the posture (201) of a vehicle based on the vehicle sensor data, and generating a subset (211) of a plurality of postures (201) by integrating the postures (201) of running motions performed in the same sub-section of a running route. A sub-segment is generated regarding each subset (211), a course of a lane in the sub-segment corresponding to the subset (211) is determined based on the postures (201) of the subset (211), the sub-segment is interpreted as a node in the graph representation of the map display, and the sub-segments are connected via edges of the graph representation such that the subsets (211) connected via the edges are based on the respective postures (201) of running motions.SELECTED DRAWING: Figure 3
