Autopilot

Generating ground truth data

The simulator sends in the following

RGB Data

Normalised Disparity Data

Producing 3D point cloud

We are able to use points = cv2.reprojectImageTo3D(depth_map, p_mat) to generate the point cloud.

p_mat = np.array([[-0.501202762, 0.000000000, 0.000000000, 0.000000000],
	[0.000000000, -0.501202762, 0.000000000, 0.000000000],
	[0.000000000, 0.000000000, 10.00000000, 100.00000000],
	[0.000000000, 0.000000000, -10.0000000, 0.000000000]
]) 
points = cv2.reprojectImageTo3D(depth_map, p_mat)

Setting up Python env

The environment involes installing the headless version of OpenCV as the normal version causes PyQt5 to crash. This script creates a Virtual Env at ~/auto

./setup_env.sh
source ~/auto/bin/activate

Generate settings.stereo.json

python generate_cameras.py > settings.stereo.json

Launching the Project

The main.py will start the sim and the rendering software as multiple processes

python main.py

Install PyTorch with CUDA

Refer to the official website for details

https://pytorch.org/get-started/locally/

pip3 install torch==1.9.1+cu111 torchvision==0.10.1+cu111 torchaudio==0.9.1 -f https://download.pytorch.org/whl/torch_stable.html
