Launch Files
Launch files provide a convenient way to start up multiple nodes and a master, as well as setting parameters.
Use roslaunch to open ZED launch files.
roslaunch zed_wrapper zed.launch
Start the node with one ZED
Use the zed.launch file to launch a single camera nodelet. It includes one instance of zed_camera.launch.
roslaunch zed_wrapper zed.launch
Start the node with multiple ZED
To use multiple ZED, launch the zed_multi_cam.launch file which describes the different cameras. This example includes two instances of zed_camera.launch.
roslaunch zed_wrapper zed_multi_cam.launch
Start the node with multiple ZED and GPUs
You can configure the wrapper to assign a GPU to a ZED. In that case, it it is not possible to use several instances of zed_camera.launch because different parameters need to be set for each ZED. A sample zed_multi_gpu.launch file is available to show how to work with different ZED and GPUs.
roslaunch zed_wrapper zed_multi_gpu.launch
