Title:
LiDAR SYSTEM
Document Type and Number:
Japanese Patent JP2023120956
Kind Code:
A
Abstract:
To provide a LiDAR system for detecting a geometric parameter for a mobile body.SOLUTION: A three-dimensional point group 201 of a supporting surface is extracted (step c) from a three-dimensional point group (b) formed by synthesizing a three-dimensional point group (a1) detected by a second LiDAR2 with a three-dimensional point group (a2) detected by a first LiDAR1. A three-dimensional point group 201 of a virtual supporting surface with a height of 0 m from the extracted three-dimensional point group of the supporting surface is generated (step d). The three-dimensional point group 201 of the supporting surface is fit to the three-dimensional point group 202 of the virtual supporting surface. The coordinate conversion matrix is calculated which the most optimally coordinate-converts the three-dimensional point group of the supporting surface into the three-dimensional point group of the virtual supporting surface. The height, the roll, and the parameter of the pitch of the coordinate conversion matrix are the height, the roll, and the geometric parameter of the pitch of the first LiDAR1.SELECTED DRAWING: Figure 4
