METHOD AND SYSTEM FOR GENERATING 3-DIMENSIONAL MAP DATA

Document Type and Number:

WIPO Patent Application WO/2024/063078

Kind Code:

A1

Abstract:

Provided is a method for generating 3-dimensional map data representing the 3-dimensional structure of a drive environment of a vehicle, wherein: a first 2-dimensional measurement area sensor (11) that acquires 3-dimensional point cloud data by measuring distance to a target point on a plane diagonally intersecting a central axis CL in the front-rear direction of a dolly (10), and an IMU that acquires positioning information enabling identification of the position and orientation of the dolly (10) are utilized to perform a coordinate conversion process based on the positioning information acquired by the IMU, on the 3-dimensional point cloud data obtained by the 2-dimensional measurement area sensor (11), to thereby convert the data into 3-dimensional point cloud data in which criterion position and orientation are identified; and the 3-dimensional point cloud data after the coordinate conversion is mapped onto a 3-dimensional space to generate 3-dimensional map data.
