Use Open3D to calculate the volume of the intersection of two point cloud AABB bounding boxes
Point cloud is a set of discrete points in three-dimensional space, which is often used to represent the shape and surface information of objects. When processing point cloud data, we often need to calculate the intersection between two point clouds, such as judging whether two point clouds intersect, calculating the intersecting volume, etc. Open3D is an open source library that provides rich point cloud processing functions. In this article, we will use Open3D to calculate the intersection volume of the AABB bounding boxes of two point clouds.
The AABB (Axis-Aligned Bounding Box) bounding box refers to an axis-aligned cube parallel to the coordinate axis. Calculating the intersecting volume of the AABB bounding box can help us understand the degree of overlap between two objects, which is very important for application scenarios such as collision detection and combined virtual and real modeling.
First, we need to import the Open3D library and read two point cloud files. Suppose we have two point cloud files named "cloud1.pcd" and "cloud2.pcd".
import open3d as o3d
# 读取点云文件
cloud1 = o3d.io.read_point_cloud("cloud1.pcd")
cloud2 = o3d
