Tutorial for RT-DETR with Isaac Sim


  1. Detect object bounding boxes using Isaac ROS RT-DETR object detection


This tutorial detects the Mac and Cheese Box mentioned in the SyntheticaDETR Object Classes section. In order to detect other objects from SyntheticaDETR Object Classes, you need to create a mesh and replace the mesh_file_path and texture_path arguments to this tutorials launch file with the mesh you generated. The tutorial on how to create a mesh using an iPhone can be found here. In order to detect other objects not supported by SyntheticaDETR, you will have to modify the launch file and replace the 2D object detection pipeline with one that supports the object you are trying to detect.
