misc3d's Introduction

Misc3D

Note: Currently, the project is under the modification to follow the latest Open3D features (tensor and tensor based geometry) and some of the functions will be refactored to support both CPU and CUDA. If you have error during building the project, please refer to previous tags.

A unified library for 3D data processing and analysis with both C++&Python API based on Open3D.

This library aims at providing some useful 3d processing algorithms which Open3D is not yet provided or not easy to use, and sharing the same data structures used in Open3D.

Misc3D also provides some useful applications:

RGBD Dense Reconstruction (app/reconstruction) tutorial
Instance-level 6D Pose Label Anotation Tool (app/label_maker), which supports both real and mixed-reality data generation. tutorial

Core modules:

common:
1. Normals estimaiton from PointMap
2. Ransac for primitives fitting, including plane, sphere and cylinder, with parallel computing supported.
3. K nearest neighbors search based on annoy. It has the similar API as open3d.geometry.KDTreeFlann class (the radius search is not supported).
preprocessing:
1. Farthest point sampling
2. Crop ROI of point clouds.
3. Project point clouds into a plane.
features:
1. Boundary points detection from point clouds.
registration:
1. Corresponding matching with descriptors.
2. 3D rigid transformation solver including Least Square, RANSAC and TEASERPP.
pose_estimation:
1. Point Pair Features (PPF) based 6D pose estimator. (This implementation is evaluated on Linemod, Linemod-Occluded and YCB-Video dataset, the performance can be found in BOP Leaderboards/PPF-3D-ICP)
2. A RayCastRenderer, which is useful for partial view point clouds, depth map and instance map generation.
segmentation:
1. Proximity extraction in scalable implementation with different vriants, including distance, and normal angle.
2. Plane segementation using iterative ransac plane fitting.
reconstruction
1. RGBD dense reconstruction, an improved version of Open3D legacy reconstruction system. See toturial for more details.

How to build

Requirements

cmake >= 3.10
python >= 3.6
eigen >= 3.3
open3d (use master branch)
pybind11 >= 2.6.2

Build

Build open3d as external library. You can follow the instruction from here guide. Build pybind11 in your system as well. If you only use C++ API, you can skip this step and just download the pre-built open3d library from official website.

Linux

Git clone the repo and run:

mkdir build && cd build
cmake .. -DCMAKE_INSTALL_PREFIX=</path/to/installation>
make install -j

If you only use C++ API, make sure you add -DBUILD_PYTHON=OFF.

After installation, add these two lines to ~/.bashrc file:

# this is not necessary if you do not build python binding
export PYTHONPATH="$PYTHONPATH:</path/to/installation>/misc3d/lib/python"
# this is necessary for c++ to find the customized installation library
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:</path/to/installation>/misc3d/lib"

Run source ~/.bashrc to save changes.

Windows

Note: In windows, you can download the latest pre-build Open3D c++ Release and python package wheel from this link.

Git clone and run: mkdir build && cd build. You can use Cmake GUI to configure your build options. Then run cmake --build . --config Release --target INSTALL to install Misc3D.
After installation, add this variable: /path/to/installation/misc3d/lib/python to your user environment variable PYTHONPATH to make sure you can import misc3d in python.

How to use

Python

The example python scripts can be found in examples/python. You can run it after you install the library successfully.

You can import misc3d same as open3d:

import open3d as o3d
import misc3d as m3d

# Estimate normals inplace.
m3d.common.estimate_normals(pcd, (640, 480), 3)

# Ransac for primitives fitting.
w, indices = m3d.common.fit_plane(pcd, 0.01, 100)
w, indices = m3d.common.fit_sphere(pcd, 0.01, 100)
w, indices = m3d.common.fit_cylinder(pcd, 0.01, 100)

# Farthest point sampling.
indices = m3d.preprocessing.farthest_point_sampling(pcd, 1000)

# Crop ROI point clouds.
pcd_roi = m3d.preprocessing.crop_roi_pointcloud(pcd, (500, 300, 600, 400), (640, 480))

# Project point clouds into a plane.
pcd_plane = m3d.preprocessing.project_into_plane(pcd)

# Boundary points detection.
index = m3d.features.detect_boundary_points(
    pcd, o3d.geometry.KDTreeSearchParamHybrid(0.02, 30))
boundary = pcd.select_by_index(index)

# Features matching using FLANN or ANNOY
# `fpfh_src` is open3d.pipeline.registration.Feature instance which is computed using FPFH 3d descriptor.
index1, index2 = m3d.registration.match_correspondence(fpfh_src, fpfh_dst, m3d.registration.MatchMethod.FLANN)
index1, index2 = m3d.registration.match_correspondence(fpfh_src, fpfh_dst, m3d.registration.MatchMethod.ANNOY)

# Solve 3d rigid transformation.
# Ransac solver
pose = m3d.registration.compute_transformation_ransac(pc_src, pc_dst, (index1, index2), 0.03, 100000)
# SVD solver
pose = m3d.registration.compute_transformation_least_square(pc_src, pc_dst)
# Teaser solver
pose = m3d.registration.compute_transformation_teaser(pc_src, pc_dst, 0.01)

# PPF pose estimator.
# Init config for ppf pose estimator.
config = m3d.pose_estimation.PPFEstimatorConfig()
config.training_param.rel_sample_dist = 0.04
config.score_thresh = 0.1
config.refine_param.method = m3d.pose_estimation.PPFEstimatorConfig.PointToPlane
ppf = m3d.pose_estimation.PPFEstimator(config)
ret = ppf.train(model)
ret, results = ppf.estimate(scene)

# Create a ray cast renderer.
intrinsic = o3d.camera.PinholeCameraIntrinsic(
    640, 480, 572.4114, 573.5704, 325.2611, 242.0489)
renderer = m3d.pose_estimation.RayCastRenderer(intrinsic)

# Cast rays for single mesh with a associated pose.
ret = renderer.cast_rays([mesh], [pose])
depth = renderer.get_depth_map()
# Convert depth map into numpy array. 
depth = depth.numpy()
# Get partial view point clouds of the mesh in the scene.
pcd = renderer.get_point_cloud()

# proximity extraction
pe = m3d.segmentation.ProximityExtractor(100)
ev = m3d.segmentation.DistanceProximityEvaluator(0.02)
index_list = pe.segment(pc, 0.02, ev)

# plane segmentation using iterative ransac
results = m3d.segmentation.segment_plane_iterative(pcd, 0.01, 100, 0.1)

# vis
# draw a pose represented as a axis
m3d.vis.draw_pose(vis, size=0.1)
# draw point clouds painted with red
m3d.vis.draw_geometry3d(vis, pcd, color=(1, 0, 0), size=3.0)
m3d.vis.draw_geometry3d(vis, mesh, color=(1, 0, 0))
m3d.vis.draw_geometry3d(vis, bbox, color=(1, 0, 0))

# logging
# the logging api is similar to open3d
# the VerbosityLevel is Info, Error, Debug and Warning
m3d.set_verbosity_level(m3d.VerbosityLevel.Error)

C++

You can run c++ examples after finish build the library, which are inside /path/to/install/misc3d/bin. The source code of examples are in examples/cpp.

misc3d's Issues

Questions about pose_estimation

Thanks for your great work firstly.
However, I have an issue about pose_estimation section.
Does pose_estimation can only detect one side of object?

My object is irregular industrial sheetmetal, as the object in scene is forward, pose_estimation can detect very well.
But if the irregular industrial sheetmetal is inverted, pose_estimation must be failed, the results of the pose form pose_estimation is always forward direction.
I know there is config.training_param_.invert_model_normal, if I set config.training_param_.invert_model_normal is true, the pose form pose_estimation is always backward direction that it cannot detect the forward direction.

My question is if there some method that I can detect the object whatever the direction is forward or backward ?

C++ installation has error loading library

Hi, I was having a hard time installing the python version but managed to install the c++ version.

However, when I tried to run the examples, there was an error saying "./ransac_and_boundary: error while loading shared libraries: libmisc3d.so: cannot open shared object file: No such file or directory"

I've checked the lib and it was in the lib directory. How should I load it?

Any suggestion to solve the problem would be very appreciated. Thanks!

ImportError: libmisc3d.so: cannot open shared object file: No such file or directory

Hi @yuecideng , I installed the Misc3D lib and successfully ran through few example python scripts in terminal. However, when I run script in pycharm then it occur import error and the terminal become like this as well. How can I solve this problem?

Question about BOP Submission: PPF_3D_ICP

While using PPF in 6D Object Pose Estimation, the scene PointCloud you used is directly created from original color and depth, or after RoI crop using bbox/mask?

How do I compile Misc3D OFFLINE?

It's been too many trouble to compile Open3D offline, so I give up. Instead, using the x86_64 (pre CXX11 ABI) with CUDA 11.x Package. However, encounter this error

...
/usr/bin/ld: /data1/install/Open3D_install/lib/libOpen3D.so: undefined reference to std::__1::ios_base::__set_badbit_and_consider_rethrow()' /usr/bin/ld: /data1/install/Open3D_install/lib/libOpen3D.so: undefined reference to typeinfo for std::__1::basic_istream<char, std::__1::char_traits >'
/usr/bin/ld: /data1/install/Open3D_install/lib/libOpen3D.so: undefined reference to `std::__1::random_device::operator()()'
...

Any advice maybe?

关于编译misc3d项目

1.open3d == 0.14.1是什么意思呢，是用open3d 为0.14.1的包去编译吗？
2.Build open3d as external library. 这个的意思是先按照https://github.com/isl-org/open3d-cmake-find-package的指示去编译open3d包吗，能不能说明下具体编译步骤，因为编译open3d按照https://github.com/isl-org/open3d-cmake-find-package的方法很难编译成功，因为需要一些很难解决的依赖问题。
谢谢你

How should 'score_thresh' be set to make sure ret is True?

In examples/python/test_ppf_estimator.py

# init ppf config
config = m3d.pose_estimation.PPFEstimatorConfig()
# init training param
config.training_param.rel_sample_dist = 0.04
config.score_thresh = 0.05
config.refine_param.method = m3d.pose_estimation.PPFEstimatorConfig.PointToPlane

What does rel_sample_dist mean?

When I set score_thresh to 0, I get "No match" as usual, I know 0 means Default, which is 0.05.
However, when I set score_thresh to 0.001, in rare cases, I still got "No match".
I assure config.score_thresh = 1e-10 may work when at least one result is needed.
Maybe there is a offical way to do it?

Aborted (core dumped)

你好，我编译成功后，最原点采样可以运行，但是其他的都无法运行，PPF报错：Aborted (core dumped)，请问你遇到过这种问题吗？

build error: undefined reference to `open3d::core::Tensor::~Tensor()'

I'm very interesting in your work. I have spent a lot of time to build the codes on ununtu20.04, but it still have problems. The environment I used is as the follow:

Ubuntu20.04
Open3D v0.15.1
python=3.7
pybind=2.10.0dev1

I have build the Open3D from source successfully. Then, I have install Misc3D according to your tutorial, the commands are as follows

git clone https://github.com/yuecideng/Misc3D.git

cd Misc3D

mkdir build
mkdir misc3d_install
cd build

cmake -DCMAKE_PREFIX_PATH=/home/subchange/dev_build/Open3D/install -DCMAKE_INSTALL_PREFIX=../misc3d_install ..

Note that the path /home/subchange/dev_build/Open3D/install is the path where I have install Open3D

Please see the errors in the follow

I do not good at c++ language. Cloud you please give me some help to build the project from source? Thank you very much.

how can i tune the parameters that i can get a better result

hi,when i use ppf_3d_icp,i find the result is not so well.
i want to know what parameter i can tune
i only tune the rel_sample_dist and score_thresh,so that more points can be counted in estimator.
what else parameters can i tune,hope your reply.

Compile misc3d in conda's virtual environment

All of my environments are installed in conda's virtual environment，And the source code is compiled to open3d with the python path specified as: /home/tsy/anaconda3/envs/ttt/bin/python, and after testing open3d is compiled successfully，How does misc3d compile into conda's virtual environment? Can't seem to specify a python path?

How did you manage to get a bop19_average_recall of 0.411 on YCB-V dataset?

How did you manage to get a bop19_average_recall of 0.411 on YCB-V dataset?
I tried gt_mask and ppf+icp on ycbv/test_targets_bop19, however, only get a score of 0.3094.
Once before I tried ppf on lm dataset, AR is 0.817, as good as yours.
I wanna know what could be wrong on ycbv, how'd you manage to fulfill sparse icp and dense icp?
Maybe you could open source your BOP submit pipeline?

can't import misc3d in python

Hi,i encounter a problem that i can't import misc3d in python.
when i finish your following guide :
1.Build open3d as external library. You can follow the instruction from here guide. Build pybind11 in your system as well. If you only use C++ API, you can skip this step and just download the pre-built open3d library from official website.
2.Git clone and run: mkdir build && cd build. You can use Cmake GUI to configure your build options. Then run cmake --build. --config Release --target INSTALL to install Misc3D.
3.After installation, add this variable: /path/to/installation/misc3d/lib/python to your system environment variable Path to make sure you can import misc3d in python.

i don't know why i still can't import misc3d,hope your rely.

Python binding failed

Hi @yuecideng ,
I followed the instruction to install and run examples in the repo and got the error with python binding, for example: farthest_point_sampling.py: TypeError: farthest_point_sampling(): incompatible function arguments. The following argument types are supported.
I use ubuntu 20.04, open3d installed with CUDA enable.
Do you know how to solve the issue?.
Thank you
