MetaGraspNet Dataset V0

This repository contains the evaluation metric code for MetaGraspNet Dataset described in the paper "MetaGraspNet: A Large-Scale Benchmark Dataset for Vision-driven Robotic Grasping via Physics-based Metaverse Synthesis" (https://arxiv.org/abs/2112.14663).

There has been increasing interest in smart factories powered by robotics systems to tackle repetitive, laborious tasks. One particular impactful yet challenging task in robotics-powered smart factory applications is robotic grasping: using robotic arms to grasp objects autonomously in different settings. Robotic grasping requires a variety of computer vision tasks such as object detection, segmentation, grasp prediction, pick planning, etc. While significant progress has been made in leveraging of machine learning for robotic grasping, particularly with deep learning, a big challenge remains in the need for large-scale, high-quality RGBD datasets that cover a wide diversity of scenarios and permutations.

To tackle this big, diverse data problem, we are inspired by the recent rise in the concept of metaverse, which has greatly closed the gap between virtual worlds and the physical world. In particular, metaverses allow us to create digital twins of real-world manufacturing scenarios and to virtually create different scenarios from which large volumes of data can be generated for training models. We present MetaGraspNet: a large-scale benchmark dataset for vision-driven robotic grasping via physics-based metaverse synthesis. The proposed dataset contains 100,000 images and 25 different object types, and is split into 5 difficulties to evaluate object detection and segmentation model performance in different grasping scenarios. We also propose a new layout-weighted performance metric alongside the dataset for evaluating object detection and segmentation performance in a manner that is more appropriate for robotic grasp applications compared to existing general-purpose performance metrics. This repository contains scripts for layout-weighted performance metric.

Object completeness refers to if a single object instance is visually crosscut into multiple segments due to occlusion.

The dataset (5 difficulties) can be accessed at:

Additionally, we provide single class multiple instances scene dataset to address the data imbalance issue. Every class used in the above datasets are used in this dataset with variable amount of instances.

Scripts

metagraspnet_metric.py

Contains general metagraspnet evaluation script

Our proposed metric focuses on evaluating top and secondary layer objects. This is driven by the fact that in real-life practical scenarios, top and secondary layer objects have a priority to be picked, while picking the rest of objects requires moving away top and secondary layer objects. Besides evaluating model performance for top and secondary objects separately, we propose a layout-weighted metric which considers the model performance on both top and secondary layer objects.

modified_coco_evaluator

Contains a script to use with coco api on the AP score for segmentation evaluation

detectron2_coco_interface

Contains a script to use with detectron2 coco api on the AP score for segmentation evaluation

You will also need to use script in modified_coco_evaluator to make it work for detectron2
