Does reading calibration file work? #69

Closed keithicus closed 8 years ago

keithicus commented 8 years ago

I'm trying to use the driver to ultimately get rectified images from an ethernet blackfly. I followed the example launch file, was able to see images and perform camera calibration. However, when i saved off the yaml and tried to use the example launch file to load the calibration file, it doesnt seem to load. No error is thrown, but if i "rostopic echo /camera/camera_info" nothing is printed to terminal and it just hangs. I triple checked the file location and even tried moving and renaming it.

Has this been tested? Is it known to work? Here's my launch file:

Turns out it was reading the calibration file, but i think the camera_info topic wasnt bneing published because nothing was subscribing to the image topic.
