A simple solution to incorporate object localization into conventional computer vision object detection algorithms.
IDEA: There aren't that many open source real-time 3D object detection. This is an example of using "more popular" 2D object detection and then localize it with a few feature points. It uses recently released Barracuda for object detection and ARFoundation for AR. It works both on IOS and Android devices.
"com.unity.barracuda": "1.0.3", "com.unity.xr.arfoundation": "4.0.8", "com.unity.xr.arkit": "4.0.8", "com.unity.xr.arcore": "4.0.8"
It is developed in Unity 2019.4.9 and requires product ready Barracuda with updated AR packages. The preview Barracuda versions seems unstable and may not work.
- Open the project in Unity (Versions > 2019.4.9).
Edit -> Player Settings -> Other XR Plug-in Management, make sure Initialize XR on Startup and Plug-in providers are marked to enable ARCamera.
- Make sure that Detector has ONNX Model file and Labels file set.
File -> Build settingschoose Detect and hit Build and run.
- For IOS, fix team setting in
Signing & Capabilities.
Use your own Model
- Convert your model into the ONNX format. If it is trained through Darknet, convert it into frozen tensorflow model first, then ONNX.
- Upload the model and label to
Assets/Models. Use inspector to check the model input and output names and modify the associated variables in here and here in
