EfficientPose

This is the official implementation of EfficientPose. We based our work on the Keras EfficientDet implementation xuannianz/EfficientDet which again builds up on the great Keras RetinaNet implementation fizyr/keras-retinanet, the official EfficientDet implementation google/automl and qubvel/efficientnet.

Installation

1. Clone this repository
2. Create a new environment with conda create -n EfficientPose python==3.6
3. Activate that environment with conda activate EfficientPose
4. Install Tensorflow 1.15.0 with conda install tensorflow-gpu==1.15.0
5. Go to the repo dir and install the other dependencys using pip install -r requirements.txt
6. Compile cython modules with python setup.py build_ext --inplace

Dataset and pretrained weights

You can download the Linemod and Occlusion datasets and the pretrained weights from here. Just unzip the Linemod_and_Occlusion.zip file and you can train or evaluate using these datasets as described below.

The dataset is originally downloaded from j96w/DenseFusion as well as chensong1995/HybridPose and were preprocessed using the generate_masks.py script. The EfficientDet COCO pretrained weights are from xuannianz/EfficientDet.

Training

Linemod

To train a phi = 0 EfficientPose model on object 8 of Linemod (driller) using COCO pretrained weights:

python train.py --phi 0 --weights /path_to_weights/file.h5 linemod /path_to_dataset/Linemod_preprocessed/ --object-id 8

Occlusion

To train a phi = 0 EfficientPose model on Occlusion using COCO pretrained weights:

python train.py --phi 0 --weights /path_to_weights/file.h5 occlusion /path_to_dataset/Linemod_preprocessed/

See train.py for more arguments.

Evaluating

Linemod

To evaluate a trained phi = 0 EfficientPose model on object 8 of Linemod (driller) and (optionally) save the predicted images:

python evaluate.py --phi 0 --weights /path_to_weights/file.h5 --validation-image-save-path /where_to_save_predicted_images/ linemod /path_to_dataset/Linemod_preprocessed/ --object-id 8

Occlusion

To evaluate a trained phi = 0 EfficientPose model on Occlusion and (optionally) save the predicted images:

python evaluate.py --phi 0 --weights /path_to_weights/file.h5 --validation-image-save-path /where_to_save_predicted_images/ occlusion /path_to_dataset/Linemod_preprocessed/

If you don`t want to save the predicted images just skip the --validation-image-save-path argument.

Inferencing

We also provide two basic scripts demonstrating the exemplary use of a trained EfficientPose model for inferencing. With python inference.py you can run EfficientPose on all images in a directory. The needed parameters, e.g. the path to the images and the model can be modified in the inference.py script.

With python inference_webcam.py you can run EfficientPose live with your webcam. Please note that you have to replace the intrinsic camera parameters used in this script (Linemod) with your webcam parameters. Since the Linemod and Occlusion datasets are too small to expect a reasonable 6D pose estimation performance in the real world and a lot of people probably do not have the exact same objects used in Linemod (like me), you can try to display a Linemod image on your screen and film it with your webcam.

Benchmark

To measure the runtime of EfficientPose on your machine you can use python benchmark_runtime.py. The needed parameters, e.g. the path to the model can be modified in the benchmark_runtime.py script. Similarly, you can also measure the vanilla EfficientDet runtime on your machine with the benchmark_runtime_vanilla_effdet.py script.

Debugging Dataset and Generator

If you want to modify the generators or build a new custom dataset, it can be very helpful to display the dataset annotations loaded from your generator to make sure everything works as expected. With

python debug.py --phi 0 --annotations linemod /path_to_dataset/Linemod_preprocessed/ --object-id 8

you can display the loaded and augmented image as well as annotations prepared for a phi = 0 model from object 8 of the Linemod dataset. Please see debug.py for more arguments.
