测试效果

废话

paint_uniform_color

将所有点绘制为统一的颜色。颜色在RGB空间中，[0,1]范围内。

测试代码

    cloud = o3d.io.read_point_cloud('D:\\TransPCD.pcd')
    return cloud

    return  cloud.voxel_down_sample(20)

def K_estimate_normals(cloud:o3d.geometry.PointCloud):
    cloud.estimate_normals(search_param=o3d.geometry.KDTreeSearchParamHybrid(radius=50, max_nn=30))
    return cloud

    print('K_CropCloud')
