How to use this package? #4

Closed ricber closed 2 years ago

ricber commented 2 years ago

Can you please explain how to read data from the ZED2 camera without a GPU by using this package? Is there a launch file or a node to launch?

Myzhar commented 2 years ago

You cannot use this package to read data without a GPU. This is a package that defines the ZED custom messages for object detection and custom services to control the ZED node. You must run a ZED Node on a machine with GPU to retrieve data

Thank you for your answer! But could you please explain what does it mean the following phrase written on this package’s README file: “ Note: this package does not require CUDA, hence it can be used to receive the ZED data also on machines not equipped with an Nvidia GPU”.

Myzhar commented 2 years ago

That means that you can use the plugins provided by this package to display ZED Object Detection data in Rviz even if the host device does not support CUDA. However, you require a ZED node running elsewhere (on a CUDA machine) and publishing the data to be subscribed for visualization.
