ros noetic moveit 将点云话题通过open3d进行三角化为一个整体后转换为对应原来点云位姿的环境scene的Python实现函数

以下是一个Python函数的示例代码，可以将点云话题通过Open3D进行三角化为一个整体，然后将其转换为对应原始点云位姿的环境scene：

import rospy
import open3d as o3d
from sensor_msgs.msg import PointCloud2
from geometry_msgs.msg import PoseStamped
from moveit_msgs.msg import CollisionObject, PlanningScene

def callback(data):
    # Convert PointCloud2 to Open3D PointCloud
    cloud = o3d.io.read_point_cloud_from_depth_image(data)
    
    # Triangulate PointCloud
    mesh, _ = cloud.compute_convex_hull()
    
    # Convert Open3D Mesh to CollisionObject
    collision_object = CollisionObject()
    collision_object.id = "mesh"
    collision_object.meshes.append(o3d.geometry.TriangleMesh(mesh))
    collision_object.mesh_poses.append(PoseStamped())

    # Publish PlanningScene
    planning_scene = PlanningScene()
    planning_scene.world.collision_objects.append(collision_object)
    planning_scene.is_diff = True
    scene_publisher.publish(planning_scene)

def listener():
    rospy.init_node('pointcloud_to_scene', anonymous=True)
    rospy.Subscriber("pointcloud_topic", PointCloud2, callback)
    rospy.spin()

if __name__ == '__main__':
    scene_publisher = rospy.Publisher('/planning_scene', PlanningScene, queue_size=10)
    listener()

请注意，此代码仅是示例，并且可能需要进行一些修改以适应您的特定应用程序。此外，确保您已正确安装所需的库，并正确发布PlanningScene消息。
