openni.launch既不是包[openni_launch]中的启动文件，也不是启动文件名[openni_launch]

Question

我想在GPU中运行我的代码。

我有两个OpenCV版本：

1. ros-3包括带有CPU的cv_bridge.............................................just。
2. 具有GPU增强功能的OpenCV需要构建cv_bridge .就用GPU

在运行代码时，系统考虑running 3 default。因此，我删除了ros-kinetic OpenCV 3 by：sudo apt remove ros-kinetic-opencv3，然后，我为OpenCV构建了带有GPU增强功能的cv_bridge，比如这 (我在catkin_ws/src中下载了vision_opencv，然后使用了catkin_make和source ./devel/setup.bash)。

我试着拍了两个摄像头：

1)照相机名称:华硕xtion当我运行照相机时：roslaunch openni_launch openni.launch，获取此错误

[openni.launch] is neither a launch file in package [openni_launch] nor is [openni_launch] a launch file name The traceback for the exception was written to the log file。

当使用这个命令：sudo apt-get install ros-kinetic-openni-launch时，它是工作的，但是使用CPU而不是GPU运行为什么？因为它安装了ros-kinetic-opencv3，所以我需要使用第一步(删除ros-kinetic opencv3 3)，这意味着一个封闭的循环。

2)相机名称: Orbbec

我做了第一步和第二步，比如ASUS xtion。当我运行照相机时：roslaunch astra_camera astra.launch得到了这个错误：

我修正了这个错误使用：sudo apt install ros-kinetic-rgbd-launch，它是工作，但运行与CPU，而不是GPU，为什么？因为它安装了ros-kinetic-opencv3，所以我需要使用第一步(删除ros-kinetic opencv3 3)，这意味着一个封闭的循环。

请帮助我或有什么建议吗？

Answer 1

看上去像是在跑

sudo apt install ros-kinetic-rgbd-launch

至少有帮助
