Closed neeba closed 9 years ago

neeba commented 10 years ago

I tried to use fovis_ros with kinect But I got these msgs:

[ WARN] [1400569554.215914118]: The tf from '/base_link' to '/camera_rgb_optical_frame' does not seem to be available, will assume it as identity!

[ERROR] [1400569559.823182401]: fovis odometry failed: INSUFFICIENT_INLIERS

Thanks for attention

Could you take a look at FovisInfo message and paste the output here?

neeba commented 10 years ago

I tried to subscribe FovisInfo message with rostopic echo but I got this err

ERROR: Cannot load message class for [fovis_ros/FovisInfo]. Are your messages built?

neeba commented 10 years ago

I changed my Cmake but I got the same errs:

[ERROR] [1400578137.105437418]: fovis odometry failed: NO_DATA [ERROR] [1400578137.197044475]: fovis odometry failed: INSUFFICIENT_INLIERS [ WARN] [1400578147.226398216]: The tf from '/base_link' to '/camera_rgb_optical_frame' does not seem to be available, will assume it as identity!

and when I tried to subscribe FovisInfo , I got the same err:

ERROR: Cannot load message class for [fovis_ros/FovisInfo]. Are your messages built?

Ok. Can you please tell me which linux and ros distro are you using?

I'm using ubuntu 13.04 and ros-hydro

plnegre commented 10 years ago

We didn't test fovis with ubuntu 13.04. In fact, ros-hydro only provide support for 12.04. However, it could work in your enviroment... We execute fovis with 12.04 and hydro.

Regarding to the errors: NO_DATA and INSUFFICIENT_INLIERS, it si common that they appear at the beginning of any execution. If they do not appear again means the odometry is being published.

The warning of the tf means that you have not set the transformation between /base_link and /camera_rgb_optical_frame. Set this using a static_transform_publisher, for example, and the warning will disappear.
