ros moveit中订阅点云话题将多个点云转环境scene的Python接口

好的,以下是一个Python接口,用于订阅点云话题并将多个点云转换为MoveIt环境scene:
```python
import rospy
import moveit_commander
import moveit_msgs.msg as moveit_msgs
import sensor_msgs.msg as sensor_msgs
import numpy as np
class PointCloudToMoveItScene(object):
def __init__(self):
self.robot = moveit_commander.RobotCommander()
self.scene = moveit_commander.PlanningSceneInterface()
def add_point_cloud(self, point_cloud_topic):
rospy.Subscriber(point_cloud_topic, sensor_msgs.PointCloud2, self.callback)
def callback(self, data):
cloud = pc2.read_points(data, skip_nans=True, field_names=("x", "y", "z"))
points = []
for p in cloud:
points.append(moveit_msgs.SolidPrimitive(type=moveit_msgs.SolidPrimitive.SPHERE, dimensions=[0.01],
center=moveit_msgs.Point(p[0], p[1], p[2])))
self.scene.addSolidPrimitives(points)
if __name__ == '__main__':
rospy.init_node('point_cloud_to_moveit_scene')
p = PointCloudToMoveItScene()
p.add_point_cloud('/camera/depth_registered/points')
rospy.spin()
```
此接口使用了与上一个例子类似的逻辑,但将其封装在了可重复使用的类中。您可以调用`add_point_cloud`方法来添加要订阅的点云话题。请注意,此接口仍然使用了`moveit_commander`和`rospy`库。
