depth-preview-neural

Live stereo depth preview intended for ONNX-based stereo models. It uses the same rectification and display pipeline as the classical preview, but is aimed at neural backends.

Examples

ag-cam-tools depth-preview-neural -a 192.168.0.201 -A --calibration-local calibration/calibration_20260225_143015_a1b2c3d4 --stereo-backend onnx --model-path model.onnx
ag-cam-tools depth-preview-neural -a 192.168.0.201 -A --calibration-slot 0 --stereo-backend igev

Backend summary

Backend	Engine	Build requirement
sgbm	OpenCV StereoSGBM	pkg-config opencv4
onnx	ONNX Runtime C API	pkg-config libonnxruntime or ONNXRUNTIME_HOME

The CLI also accepts igev and foundation as aliases for onnx.

Sensor modes

depth-preview-neural requires a stereo Lucid camera. The mono refusal behavior matches depth-preview-classical — see that page for the exact error message.

Notes

• depth-preview-neural uses the same major CLI options as depth-preview-classical.
• Runtime SGBM tuning keys are not enabled in this command.
• The ONNX backend automatically picks the best execution provider available at runtime, preferring CUDA and CoreML over CPU when present.

See ../backends/igev-setup.md for model export and ONNX runtime setup.
