Bandwith and framerate issues #58

Open gscortichini opened 8 years ago

gscortichini commented 8 years ago

Hi everyone, i`m using a Pointgrey Blackfly Camera (BFLY-PGE-23S6C, 1920x1200) through ROS pointgrey_camera_driver. My camera works perfectly on FlyCap2, where i can easly reach 40Hz of framerate (the max framerate for that camera model is 41).

When i work with point_grey_camera driver with this launch file:

``` ```

I can reach only 12Hz of framerate on "camera/image_raw" topic. It doesn`t matter which videomode i choose, the max framerate is always 12Hz.

I tried Raw8,Raw16,Mono8 and Mono16. I get always the same max framerate. This means that the Bandwith is variable, but not directly by setting one specific parameter.

After this, when i run Flycap2, i noticed that the Packet Size and Packet Delay values were changed, and obviously the Bandwith too.

Is there anything i can do in order to increase the framerate and reach 35Hz or 40Hz?

did you find any solution for this? I am using Chameleon 3 on one of my older computer it works fine but on the new one I can't get a frame rate higher than 5.6

Try adjusting the frame rate by running rosrun rqt_reconfigure rqt_reconfigure

@brianabrams It works but you need to launch rqt_reconfigure everytime you use the driver?

Try turn off auto_shutter and manual set the shutter speed in the launch file.
