Point clouds can be viewed as NumPy arrays, so modifying them is possible using all the familiar NumPy functionality: import numpy as np import pcl p = pcl.PointCloud(10) # "empty" point cloud a = np.asarray(p) # NumPy view on the cloud a[:] = 0 # fill with zeros print(p[3]...
带有PointCloud 数据的 ChefBot 要开始键盘遥控操作,请使用以下命令: $ roslaunch ChefBot_bringup keyboard_teleop.launch 要查看正在创建的地图,我们需要使用以下命令在远程系统上启动 RViz: $ roslaunch ChefBot_bringup view_navigation.launch 在RViz 中查看机器人后,可以使用键盘移动机器人并查看正在创建的地图。

接下来,仍以 example.py 为例,看看 Run As Python Coverage 功能展现出的结果。选择Run As -> Python Coverage,控制台 Console 中显示出了程序的运行结果。切换到刚才打开的 Code Coverage Results View 视图,单击左栏中的 example.py。 代码运行过程中的覆盖情况很清楚地显示在右栏中。
