problem with fovis

edit

Hi guys

I tried to run fovis fovis_mono_depth_odometer then I used freenect_camera to get data from my kinect

I wrote this launch file for that:

<launch>

<remap from="/camera/rgb/image_rect" to="/rgb/image_raw"/>
<remap from="/camera/rgb/camera_info" to="/rgb/camera_info"/>
<remap from="/camera/depth_registered/image_rect" to="/depth_registered/image_raw"/>
<remap from="/camera/depth_registered/camera_info" to="/depth_registered/camera_info"/>
<node
    pkg="fovis_ros"
    type="fovis_mono_depth_odometer"
    name="fovis"
    output="screen"
/>

<node
    pkg="freenect_camera"
    type="freenect_node"
    name="Driver"
    output="screen"
/>

</launch>

But I got this err:

This is graph of my nodes

and fovis didn't work.

any suggestion about my problem?

Thanks

Hamid
