All credit for the model architecture and training goes to the original authors. - -### Inspiration from Prior ROS2 Wrappers -This package was inspired by the following excellent ROS2 wrapper implementations: - -- **Depth Anything V2 ROS2**: [grupo-avispa/depth_anything_v2_ros2](https://github.com/grupo-avispa/depth_anything_v2_ros2) -- **Depth Anything ROS2**: [polatztrk/depth_anything_ros](https://github.com/polatztrk/depth_anything_ros) -- **TensorRT Optimized Wrapper**: [scepter914/DepthAnything-ROS](https://github.com/scepter914/DepthAnything-ROS) - -Special thanks to these developers for demonstrating effective patterns for ROS2 integration. - ---- - -## Overview - -This aims to be a camera-agnostic ROS2 wrapper for Depth Anything 3 (DA3), providing real-time monocular depth estimation from standard RGB images. This package is designed to work seamlessly with any camera publishing standard `sensor_msgs/Image` messages. - -### Key Features - -- **TensorRT-Optimized**: Production backend using TensorRT 10.3 for maximum performance (40+ FPS on Jetson Orin NX) -- **Camera-Agnostic Design**: Works with ANY camera publishing standard ROS2 image topics -- **Multiple Model Support**: All DA3 variants (Small, Base, Large) with TensorRT FP16 -- **Shared Memory IPC**: Low-latency host-container communication via `/dev/shm` (~23ms total frame time) -- **Multi-Camera Support**: Run multiple instances for multi-camera setups -- **Real-Time Performance**: 23+ FPS real-world, 43+ FPS processing capacity on Jetson Orin NX 16GB -- **Production Ready**: Comprehensive error handling, logging, and testing -- **Docker Support**: Pre-configured Docker and Docker Compose files for Jetson -- **One-Click Demo**: `./run.sh` handles everything (engine build, service start, container launch) -- **Performance Profiling**: Built-in benchmarking and profiling tools -- **INT8 Quantization**: Model compression for even faster inference -- **Complete Documentation**: Sphinx-based API docs with comprehensive tutorials -- **RViz2 Visualization**: Pre-configured visualization setup - -> **Important**: This project has migrated to **TensorRT as the production inference backend**. The architecture uses a host-container split where TensorRT 10.3 runs on the Jetson host for maximum performance (23+ FPS real-world, 43+ FPS capacity), while the ROS2 container communicates via shared memory IPC. PyTorch remains in the container only as a library dependency and development/testing fallback - it is NOT used for production inference. - -### Production Architecture - -This project uses a **host-container split architecture** optimized for Jetson deployment: - -``` -+----------------------------------------------------------+ -| HOST (JetPack 6.x) | -| +----------------------------------------------------+ | -| | TRT Inference Service (trt_inference_shm.py) | | -| | - TensorRT 10.3 loads DA3 engine | | -| | - ~15ms inference latency | | -| +----------------------------------------------------+ | -| ^ | -| | /dev/shm/da3 (shared memory) | -| v | -| +----------------------------------------------------+ | -| | Docker Container (L4T r36.4.0) | | -| | - ROS2 Humble + camera drivers | | -| | - SharedMemoryInferenceFast (~8ms IPC) | | -| | - Publishes /depth, /depth_colored topics | | -| +----------------------------------------------------+ | -+----------------------------------------------------------+ -``` - -**Why this architecture:** -- TensorRT 10.3+ required for DA3's DINOv2 backbone (TRT 8.x fails) -- Container TRT bindings are broken in current dustynv images -- Shared memory IPC reduces latency from ~40ms (file-based) to ~8ms -- Total frame time: ~23ms (15ms inference + 8ms IPC) - -### Supported Platforms - -- **Primary Target**: NVIDIA Jetson Orin NX/AGX (JetPack 6.x, TensorRT 10.3+) -- **ROS2 Distribution**: Humble Hawksbill -- **TensorRT**: 10.3+ required for DA3 model support (DINOv2 backbone) -- **Python**: 3.10+ - -> **Important**: TensorRT 10.3+ is required.
