Vision Factory

This is a general repo for training and testing vision tasks (monocular 3D detection, segmentation, monodepth and more).

This repo contains the training/inference/export codes to obtain the three independent network models trained with completely different strategies (Notice: ROS Nodes and Dataset bridges are in other repos). Demonstration-Ready Models are in release page.

The general starting points/runtime backbone will be in the "scripts", common modules, runtime plugins and helper functions will be in "vision_base".

For different tasks, we may meed to overwrite parts of the dataloader / model / evaluator. Checkout mono3d, segmentation, monodepth for their settings and module overview.

Notice For FSNet Users: The training/testing scripts, vision_base and even the monodepth folder are basically the same as FSNet. For monodepth tasks, for now it is completely fine to directly transferring configs/checkpoints across this two repos. We try to guarantee the backward compliance, especially in the scripts and vision_base package.

Notice For VisualDet3d Users: This repo mainly extracts the MonoFlex model from visualDet3D. However after a complete redesign in the data section for more general usage and works in the new paper, we sadly determined not to follow the original design and merge with the FSNet standard.

In this main page, we will focus on the general usage of vision_base.

(New) Launching Web Demo

We introduced ways to demonstrate the result of the pretrained ONNX models. (So that we could check results with any data at hand)

The onnxmodels are created with the export scripts. And we provide pretrained models in release page of inference.

Install streamlit and run the following command from the base directory:

python3 -m streamlit run demos/web_demo.py --server.fileWatcherType none

Alt text

We could upload any images and check the visualized results. If we do not indicate the camera parameters, the web-page will make a pseudo camera parameter for the demo usage.

The pretrained model is trained on road scenes so we could expect the potential and limitation of the models.

Launching ROS Demo

Check this repo for launching inference demo in ROS1/ROS2.

Pre-Use

We recommend torch > 1.10 or torch 2.0 with the corresponding CUDA versions. run

./make.sh

This operation will build the dcn module inplace and does not install anything.

Common Notice: Make sure the nvcc version (nvcc --version) and the pytorch cuda version (torch.version.cuda) aligned.

General Usage

Start Everything in the base directory of this repo. Please check out each tasks(mono3d/segmentation/monodepth) for dataset preparation.

Training:

### multi-gpu training
./launcher/train.sh $CONFIG_PATH $COMMA_GPULIST $EXPERIMENT_LOGGING_NAME

### single-gpu training / debugging
python3 scripts/train.py $CONFIG_PATH $EXPERIMENT_LOGGING_NAME

Single testing:

python3 scripts/test.py $CONFIG_PATH $SINGLE_GPU $CHECKPOINT

Check the Logging

By default, the train scripts and vision_base will create a detailed tensorflow report besides the logging from specific packages. The logging will be in ./workdirs/\$NAME_IN_CONFIG/log/${EXPERIMENT_LOGGING_NAME}config=${CONFIG_NAME}, we suggest tensorboard open in workdirs/$NAME_IN_CONFIG/log/ or ./workdirs/.

The tensorboard report will include the full expanded config file

and the git changes / git commits

with these info, it is easier to reproduce the experiments when we are tuning parameters in config or modifying codes.

Tips for Developing

In general, we recommend not making breaking change in vision_base (adding more functionalities is generally fine, and extrely welcome for features/bugs report).

If we are starting a new project with new data settings / new models / new strategies, it is recommended to start a new folder and overwrite existing classes, and write config files pointing to new modules. This is achieved by builder and find_object.

Check the codes in segmenatation for how to start a simple new project.

Check the codes in mono3d for how to overwrite data pipeline for complex tasks.
