I have developed a ROS2 package for performing object detection (Microsoft COCO objects, eg car/bicycle/person etc). It listens to topic /image and publishes ROS2 Detection2DArray messages on topic /detected\_objects. It uses PyTorch MobileNet to perform the object detection.

There are certainly more sophisticated vision perception systems out there, eg [NVIDIA Isaac](https://developer.nvidia.com/isaac), but the aim of this package is to be easy to setup and use and also to use standard ROS2 messages.

I hope this may be of interest.
