StereoNet is an end-to-end deep architecture for real-time stereo matching that produces high-quality, edge-preserved disparity maps from a rectified stereo image pair.
This is based on the implementation of StereoNet found here. This repository contains scripts for optimized on-device export suitable to run on Qualcomm® devices. More details on model performance across various devices, can be found here.
Qualcomm AI Hub Models uses Qualcomm AI Hub Workbench to compile, profile, and evaluate this model. Sign up to run these models on a hosted Qualcomm® device.
Use our lightweight command-line interface to inspect and download StereoNet:
pip install qai_hub_models_cli # (the CLI is also available with the qai-hub-models package)
# Inspect the model and list the available download options
qai-hub-models info StereoNet
# Print performance and accuracy metrics
qai-hub-models perf StereoNet
qai-hub-models numerics StereoNet
# Download a ready-to-deploy asset
qai-hub-models fetch StereoNet --runtime tflite --precision floatSee the CLI README for the full list of commands and filters.
Install the package via pip:
# NOTE: 3.10 <= PYTHON_VERSION < 3.14 is supported.
pip install qai-hub-models
pip install git+https://github.com/andrewlstewart/StereoNet_PyTorch@3cb3a02Sign-in to Qualcomm® AI Hub Workbench with your
Qualcomm® ID. Once signed in navigate to Account -> Settings -> API Token.
With this API token, you can configure your client to run models on the cloud hosted devices.
qai-hub configure --api_token API_TOKENNavigate to docs for more information.
Run the following simple CLI demo to verify the model is working end to end:
python -m qai_hub_models.models.stereonet.demoMore details on the CLI tool can be found with the --help option. See
demo.py for sample usage of the model including pre/post processing
scripts. Please refer to our general instructions on using
models for more usage instructions.
By default, the demo will run locally in PyTorch. Pass --eval-mode on-device to the demo script to run the model on a cloud-hosted target device.
To run the model on Qualcomm® devices, you must export the model for use with an edge runtime such as TensorFlow Lite, ONNX Runtime, or Qualcomm AI Engine Direct. Use the following command to export the model:
qai-hub-models export stereonet --target-runtime tflite --precision floatAdditional options are documented with the --help option.
