使用open3d合并ply模型
import open3d as o3d
from scipy.ndimage import binary_fill_holes
def 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)
合并后的ply文件：
