Error when starting camera

[GettingChen]

Now it worked on my indigo ,but when I run
roslaunch ccny_openni_launch openni.launch
I get some errors

Thanks to your reply!

Now it works on my computer ,but where is your ccny_rgbd/launch/rviz.cfg.I can't find this file.

[EricLYang]

Sorry, was overly booked the last week. You don't need the rviz.cfg, what you can do is:

rostopic list

get the pose and the other message published, then open rviz

rosrun rviz rviz

to add a pose or other component to visualize the message.

you can also try

rostopic echo /message

to see if it is successfully published

[GettingChen]

When I run the program, I can only get the real-time point cloud, as shown below

How can I get a complete map of the house like in your paper？Thanks in advance.

[EricLYang]

you need checkout to branch 3Dto2D-dense

https://github.com/ccny-ros-pkg/ccny_rgbd_tools/blob/3Dto2D-dense/ccny_rgbd/src/apps/keyframe_mapper.cpp

you need to call bool KeyframeMapper::savePcdMap(const std::string& path) to save the global pointcloud, as it differs from VO , it is keyframe based mapping.

you can simply call bool KeyframeMapper::savePcdMapSrvCallback( to save the pcd

[GettingChen]

When I compile the branch 3Dto2D-dense,I got some new problems
`

The weird thing is that I have installed pcl, but I still get this error.Do you have any idea about this?

[GettingChen]

I will not be able to graduate soon. I hope to get a master's degree by improving your procedures. I really need your help and look forward to your reply.
