[ros-users] Frame rate low

[liuwei at cmu.edu]

Hi,

I could only get a very low frame rate with openni_kinect on the ROS.
I am using a kinect camera, with the command of rosbag record -a,
I find that the frame rate is just about 3fps. Even when I just record a
single
topic, the fps is still low, is about 8 fps, with a extremely big file. Can
you help me about this?

And Is there a instruction about the data in every topic?
topics like
/camera/depth/camera_info
/camera/depth/disparity
/camera/rgb/image

Regards
Wei
