在使用CloudCompare导入pcd文件时，弹窗报错：

An error occurred while loading 'original_point_cloud': the third-party library in charge of saving/loading the file has failed to perform the operation

然而我直接用Python脚本是可以预览的：

未能理解确切原因，但有解决方法：

写一个Python脚本，将pcd格式的点云文件转为ply格式：

import open3d as o3d

def convert_pcd_to_ply(input_file_path, output_file_path):
    # 读取PCD文件
    point_cloud = o3d.io.read_point_cloud(input_file_path)

    # 检查点云是否成功加载
    if point_cloud.is_empty():
        print(f"Error loading point cloud from {input_file_path}. Please check the file path or format.")
        return

    # 将点云保存为PLY格式
    o3d.io.write_point_cloud(output_file_path, point_cloud)
    print(f"Point cloud saved as {output_file_path}")

# 使用示例
input_file_path = "original_point_cloud.pcd"  # 输入文件路径
output_file_path = "converted_point_cloud.ply"  # 输出文件路径

convert_pcd_to_ply(input_file_path, output_file_path)

再次导入ply文件，没有报错了：
