Keypoint-GraspNet (KGN)

Code release for our papers: ICRA'23 Keypoint-GraspNet: Keypoint-based 6-DoF Grasp Generation from the Monocular RGB-D input and IROS'23 KGNv2: Separating Scale and Pose Prediction for Keypoint-based 6-DoF Grasp Synthesis on RGB-D input.

Installation

Please follow INSTALL.md to prepare for the environment.

Demo

First download our released weights for KGNv1 and/or KGNv2. Put them under the folder ./exp. Then run the demo on real world data via:

bash experiments/demo_kgnv{1|2}.sh

NOTE: the released KGNv1 weight is trained on single-object data, while the KGNv2 weight is trained on multi-object data.

You should seem example results (from kgnv2):

Train and evaluate

Data generation

The dataset used in the papers can be downloaded from the links: sinlge-object and multi-object. Download, extract, and put them in the ./data/ folder.

Alternatively, you can also generate the data by yourself. For single-object data generation:

python main_data_generate.py --config_file lib/data_generation/ps_grasp_single.yaml

Multi-object data generation:

python main_data_generate.py --config_file lib/data_generation/ps_grasp_multi.yaml

Train

First download pretrained ctdet_coco_dla_2x model following the instruction. Put it under ./pretrained_weights/ folder.

Then run the training code.

bash experiments/train_kgnv{1|2}.sh {single|multi}

single/multi: Train on single- or multi-object data.

Evaluation

bash experiments/test_kgnv{1|2}.sh {single|multi} {single|multi}

First single/multi: Evaluate the weight trained on single- or multi-object data.

Second single/multi: Evaluate on single- or multi-object data.

Acknowledgement

Some code borrowed from the CenterPose and Acronym.
