News: We released the codebase v0.17.2.
In addition, we have preliminarily supported several new models on the v1.0.0.dev0 branch, including DGCNN, SMOKE and PGD.
Note: We are going through large refactoring to provide simpler and more unified usage of many modules. Thus, few features will be added to the master branch in the following months.
The compatibilities of models are broken due to the unification and simplification of coordinate systems. For now, most models are benchmarked with similar performance, though few models are still being benchmarked.
You can start experiments with v1.0.0.dev0 if you are interested. Please note that our new features will only be supported in v1.0.0 branch afterward.
In the nuScenes 3D detection challenge of the 5th AI Driving Olympics in NeurIPS 2020, we obtained the best PKL award and the second runner-up by multi-modality entry, and the best vision-only results.
Code and models for the best vision-only method, FCOS3D, have been released. Please stay tuned for MoCa.

Introduction
English | 简体中文
The master branch works with PyTorch 1.3+.
MMDetection3D is an open source object detection toolbox based on PyTorch, towards the next-generation platform for general 3D detection. It is a part of the OpenMMLab project developed by MMLab.
Major features
-
Support multi-modality/single-modality detectors out of box
It directly supports multi-modality/single-modality detectors including MVXNet, VoteNet, PointPillars, etc.
-
Support indoor/outdoor 3D detection out of box
It directly supports popular indoor and outdoor 3D detection datasets, including ScanNet, SUNRGB-D, Waymo, nuScenes, Lyft, and KITTI. For nuScenes dataset, we also support nuImages dataset.
-
Natural integration with 2D detection
All the about 300+ models, methods of 40+ papers, and modules supported in MMDetection can be trained or used in this codebase.
-
High efficiency
It trains faster than other codebases. The main results are as below. Details can be found in benchmark.md. We compare the number of samples trained per second (the higher, the better). The models that are not supported by other codebases are marked by

Like MMDetection and MMCV, MMDetection3D can also be used as a library to support different projects on top of it.
