Open3D

1.1 包围盒法介绍：

求解离散点最优包围空间

常用的凸包算法：
AABB
OOB

2.1 python代码

conda activete deeplabv3plus(环境名称–安装好open3D的)
python demo.py

import open3d as o3d

def main():
    # 读取点云数据
    pc = o3d.io.read_point_cloud("downsampled_pcd.pcd")

    # 获取点云的包围盒
    aabb_box = pc.get_axis_aligned_bounding_box()
    aabb_box.color = (1, 0, 0)

    obb_box = pc.get_oriented_bounding_box()
    obb_box.color = (0, 1, 0)

    # 计算包围盒体积
    aabb_volume = aabb_box.volume()
    obb_volume = obb_box.volume()

    print(f"aabb算法包围盒体积: {aabb_volume} ")
    print(f"obb算法包围盒体积: {obb_volume} ")

    # 可视化
    o3d.visualization.draw_geometries([aabb_box, obb_box, pc], "result", 800, 600, 50, 50, False, False, True)
