Getting Started

This code runs with Python 3.8.17, Pytorch 2.0.1 and TensorRT 8.6.0

- ./src/

• train.py: The training code of the model
• NET1.py: The network structure of the model1
• dataLoader.py: The data loader of the model
• rtholo.py: The code of the real-time holography
• predict_rgbd_multiprocess.py: The testing code of the model
• trt.py: The code of TensorRT class
• getBlaze.py: This code is for generating a blazed grating
• GCD_ctrl.py: This code is for controlling the motorized linear stage
• depthcamera_ctrl.py: This code is for controlling the depth camera Realsense D435
• gxipy: The SDK of the Daheng camera

- ./trt/

• trt_create_v1.py: This code is used to generate the TRT model
• trt_inference_v1.py: This code is used to test the TRT model

Training

python ./src/train.py --p_loss --l2_loss --num_epochs 60 --data_path <The address of your training set>

Testing

python predict_rgbd_multiprocess.py

Checkpoints

We provide pretrained checkpoints. The pre-trained models in - ./src/checkpoints/CNN_1024_30/53.pth

Ackonwledgement

We are thankful for the open source of tensor_holography ,HoloEncoder, HoloEncoder-Pytorch-Version and Self-Holo. These works are very helpful for our research.
