In developing additional application with AI, trained AI model on Caffe/Tensorflow/ONNX framework is needed needs to be convert to binary file (cavalry.bin), which is executable executed by accelerator H/W (CVFlow) inside embedded to AI camera.

The CV tool is what does processes this conversion process.

...

Note

  • The target users of this document are supposed to have skill of training AI model.

  • The cvtool is not the tool for training AI model.
    Users have to train it in each framework previouslyin advance.

  • The cvtool handles CNN as target AI model.

  • The model of tensorflow v2.x needs to be converted to tflite in advance.

  • Pytorch model needs to be converted to ONNX in advance

...

The CV Tool handles colored items in the figure below.

...

Retraining of a model is not included in this process.

...

  • only 16bit

  • 16bit/8bit mixed (the CV tool decides data length of each operation)

  • only 8bit

The inference time of 8bit operation results in faster inference time and less accuracy than 16bitis faster but less accurate compared to 16bit operation.

Preparation

...

Please refer here for the environment construction procedure.

...

Please refer to the following page pages for model conversion.
