TensorRT Depth Anything for Efficient Inference

city_depth_anything_1024x256.mp4

Purpose

This package estimates depth for arbitrary images using TensorRT Depth Anything for efficient and faster inference. Specifically, this supports multi-precision and multi-device inference for efficient inference on embedded platforms.

Setup

Install basic libraries for inference on GPUs including CUDA, cuDNN, TensorRT (>=8.6), and OpenCV.

Also, you'll need to install them as below.

sudo apt-get install libgflags-dev
sudo apt-get install libboost-all-dev

ONNX Conversion

Please use the export_to_onnx.py from the following repository for the converter.

https://github.com/spacewalk01/depth-anything-tensorrt

Build sources

git clone git@github.com:tier4/trt-depth-anything.git
cd trt-depth-anything.git
cd build/
cmake ..
make -j

Start inference

-Build TensoRT engine

./trt-depth-anything --onnx depth_anything_vitb14.onnx --precision fp32

-Infer from a Video

./trt-depth-anything --onnx depth_anything_vitb14.onnx --precision fp32 --v {VIDEO PATH} --depth {gray/magma/jet} (--max_depth VALUE)

-Infer from images in a directory

./trt-depth-anything --onnx depth_anything_vitb14.onnx --precision fp32 --d {Directory PATH} --depth {gray/magma/jet} (--max_depth VALUE) (--save_detections --save_detections_path {SAVE_PATH}) (--dont_show)
