使用open3d合并ply模型

import open3d as o3d
from scipy.ndimage import binary_fill_holesdef merge_ply(ply1, ply2, output_path):# 加载两个多边形模型mesh1 = o3d.io.read_triangle_mesh(ply1)mesh2 = o3d.io.read_triangle_mesh(ply2)# 使用 + 运算符合并两个多边形模型merged_mesh = mesh1 + mesh2# 去除合并后的重复顶点和三角形merged_mesh.remove_duplicated_vertices()merged_mesh.remove_duplicated_triangles()# 可选：合并近距离的顶点# merged_mesh.merge_close_vertices(distance=0.001)# 保存或可视化合并后的多边形模型o3d.io.write_triangle_mesh("path_to_output_mesh.ply", merged_mesh)o3d.visualization.draw_geometries([merged_mesh])if __name__ == '__main__':ply1 = "Left-Caudate.ply"ply2 = "Left-Lenticula.ply"merge_ply_path = "merged_mesh.ply"merge_ply(ply1, ply2, merge_ply_path)
