TODO List

• Training and inference code.
• Pipeline to reproduce the evaluation results on the proposed OnePose dataset.
• OnePose Cap app: we are preparing for the release of the data capture app to the App Store (iOS only), please stay tuned.
• Demo pipeline for running OnePose with custom-captured data including the online tracking module.

Installation

conda env create -f environment.yaml
conda activate onepose

We use SuperPoint and SuperGlue for 2D feature detection and matching in this project. We can't provide the code directly due its LICENSE requirements, please download the inference code and pretrained models using the following script：

REPO_ROOT=/path/to/OnePose
cd $REPO_ROOT
sh ./scripts/prepare_2D_matching_resources.sh

COLMAP is used in this project for Structure-from-Motion. Please refer to the official instructions for the installation.

[Optional, WIP] You may optionally try out our web-based 3D visualization tool Wis3D for convenient and interactive visualizations of feature matches. We also provide many other cool visualization features in Wis3D, welcome to try it out.

# Working in progress, should be ready very soon, only available on test-pypi now.
pip install -i https://test.pypi.org/simple/ wis3d

Training and Evaluation on OnePose dataset

Dataset setup

1. Download OnePose dataset from onedrive storage and extract them into $/your/path/to/onepose_datasets. The directory should be organized in the following structure:

   |--- /your/path/to/onepose_datasets
   |       |--- train_data
   |       |--- val_data
   |       |--- test_data
   |       |--- sample_data
   

2. Build the dataset symlinks

   REPO_ROOT=/path/to/OnePose
   ln -s /your/path/to/onepose_datasets $REPO_ROOT/data/onepose_datasets

3. Run Structure-from-Motion for the data sequences

   Reconstructed the object point cloud and 2D-3D correspondences are needed for both training and test objects:

   python run.py +preprocess=sfm_spp_spg_train.yaml # for training data
   python run.py +preprocess=sfm_spp_spg_test.yaml # for testing data
   python run.py +preprocess=sfm_spp_spg_val.yaml # for val data
   python run.py +preprocess=sfm_spp_spg_sample.yaml # an example, if you don't want to test the full dataset

Inference on OnePose dataset

1. Download the pretrain weights pretrained model and move it to ${REPO_ROOT}/data/model/checkpoints/onepose/GATsSPG.ckpt.

2. Inference with category-agnostic 2D object detection.

   When deploying OnePose to a real world system, an off-the-shelf category-level 2D object detector like YOLOv5 can be used. However, this could defeat the category-agnostic nature of OnePose. We can instead use a feature-matching-based pipeline for 2D object detection, which locates the scanned object on the query image through 2D feature matching. Note that the 2D object detection is only necessary during the initialization. After the initialization, the 2D bounding box can be obtained from projecting the previously detected 3D bounding box to the current camera frame. Please refer to the supplementary material for more details.

   # Obtaining category-agnostic 2D object detection results first.
   # Increasing the `n_ref_view` will improve the detection robustness but with the cost of slowing down the initialization speed.
   python feature_matching_object_detector.py +experiment=object_detector.yaml n_ref_view=15
   
   # Running pose estimation with `object_detect_mode` set to `feature_matching`.
   # Note that enabling visualization will slow down the inference.
   python inference.py +experiment=test_GATsSPG.yaml object_detect_mode=feature_matching save_wis3d=False

3. Running inference with ground-truth 2D bounding boxes

   The following command should reproduce results in the paper, which use 2D boxes projected from 3D boxes as object detection results.

   # Note that enabling visualization will slow down the inference.
   python inference.py +experiment=test_GATsSPG.yaml object_detect_mode=GT_box save_wis3d=False # for testing data

4. [Optional] Visualize matching and estimated poses with Wis3D. Make sure the flag save_wis3d is set as True in testing and the full images are extracted from Frames.m4v by script scripts/parse_full_img.sh. The visualization file will be saved under cfg.output.vis_dir directory which is set as GATsSPG by default. Run the following commands for visualization:

   sh ./scripts/parse_full_img.sh path_to_Frames_m4v # parse full image from m4v file
   
   cd runs/vis/GATsSPG
   wis3d --vis_dir ./ --host localhost --port 11020

   This would launch a web service for visualization at port 11020.

Training the GATs Network

1. Prepare ground-truth annotations. Merge annotations of training/val data:

   python run.py +preprocess=merge_anno task_name=onepose split=train
   python run.py +preprocess=merge_anno task_name=onepose split=val

2. Begin training

   python train.py +experiment=train_GATsSPG task_name=onepose exp_name=training_onepose

All model weights will be saved under ${REPO_ROOT}/data/models/checkpoints/${exp_name} and logs will be saved under ${REPO_ROOT}/data/logs/${exp_name}.
