Zed Launch #89

Closed CapitalZe closed 6 years ago

CapitalZe commented 6 years ago

Before I make any changes anywhere I'd like to confirm what I infer. Referring to this issue.

I have a ZED and am currently getting the error:

[ INFO] [1537347897.712051688]: camera calibration URL: file:///home/nvidia/.ros/camera_info/camera.yaml
[ INFO] [1537347897.712238568]: Unable to open camera calibration file [/home/nvidia/.ros/camera_info/camera.yaml]

[FATAL] [1537347897.756897384]: Failed to initialize gscam stream!

From reading the above linked issue, it apparent that I didn't launch the ros-zed-wrapper node.

So my question is, must I emend the everything.launch file to remove the gscam input and replace it with this or must I simply change the pertinent topic of the caffe_ros.cpp node?

Cheers!

That's right, if you use ZED ROS node then you don't need to run gscam node. In such case you can create your own .launch file, based on trailnet_debug_zed.launch you referenced. You don't need to change the source code, caffe_ros ROS node has a parameter, camera_topic which can be used to change camera topic when running caffe_ros via rosrun or .launch file.

Thanks! Really helpful. As of now it's working.
