We had a blast at ICCV during our tutorial, as we open sourced and demoed Kinect Fusion (more on that soon), as well as had a lot of interesting discussions with our colleagues from all around the world. I’m curious to see how things evolve in the next 2 years and whether ICCV 2013 will be more 3D centric than 2011 was.
If you’re interested in joining our code sprints, we’re currently accepting applications for the PCL Trimble Code Sprint (TRCS).
It is our immense pleasure to announce the beginning of a new PCL Code Sprint sponsored by Toyota: PCL-TOCS!
PCL Code Sprints are intended to rapidly advance the capabilities of the Point Cloud Library in a certain area/subject by offering stipends to talented student developers and pairing them with knowledgeable mentors for several months of accelerated software development. These sprints have been inspired by the Google Summer Of Code (GSOC) initiative, and we will be following the same basic model. Projects will run for an initial period of 3 months with the same structure and performance evaluations as the GSOC program, and all of the code produced will be open source.
For this fall’s PCL-Toyota Code Sprint, we have identified the following important areas for further development in PCL, and we are therefore searching for outstanding candidates (and mentors) to work on the following projects:
Surface reconstruction and point cloud smoothing
Accurate surface reconstruction and point cloud smoothing have been demonstrated in specific test environments with minimal clutter and when the object of interest fills most of the field of view. However, additional algorithms are needed when performing surface reconstruction and/or point cloud smoothing in a cluttered space. In this project, students will work to develop algorithms capable of smoothing noisy point clouds and reconstructing surfaces of objects so that they can be compared against a collection of known 3D objected models. The algorithms developed must be able to operate in a cluttered home or health-care environment, and they must be tolerant of noisy point cloud data (such as those acquired by sensors like the Microsoft Kinect). This project will also investigate the reliability and accuracy of different surface reconstruction techniques when data is acquired from a moving sensor.
CPU and GPU optimizations
CPU and GPU optimizations for real-time global point cloud localization
In this project, students will work to develop CPU and GPU optimizations to enable real-time 3D place recognition. Existing algorithms are able to process a point cloud containing a partial view of an environment and subsequently localize it within a previously captured 3D map of the complete environment. However, this task is very computationally expensive, and many improvements are needed to make these approaches practical for real world uses. The goal of this project is to develop highly optimized implementations of a number of general purpose search and feature extraction algorithms that can be used in a variety of applications.
CPU and GPU optimizations for real-time 3D segmentation and boundary extraction
With image segmentation, being able to perform multiple levels of segmentation on a single image is becoming more common to aid in recognition tasks. For instance, it is common to use coarse segmentation initially to identify regions of interest and then use a finer segmentation for boundary detection of individual objects in the scene. In this project, the student will develop real-time algorithms for segmenting 3D images, using CPU and GPU optimizations so that multiple levels of segmentation be computed quickly.
The above projects will run for a period of 3 months divided into two terms. Each student developer will receive a stipend of $5000 for their contributions, subject to satisfactory mid-term and final evaluations.
a list of projects (emphasis on open source projects please) that they contributed to in the past
Advanced C++ programming skills are required for all projects. Please remember that this is a unique opportunity to work with some of the world’s best 3D perception researchers!
Interested mentors should send a brief e-mail to the address mentioned above pointing out their time commitments and expertise in the field.
The Intelligent Robots and Systems (IROS) conference this year is going to be loaded with great presentations and interesting discussions. Willow Garage is organizing a number of events, including the PR2 Workshop, as well as a technical tour. PCL will be present en pleine forme with its second tutorial. Be there if you care about 3D point cloud perception!
Earlier last week we released PCL 1.0. We’ve been working on this project for some time now, but the past few weeks have been nothing but bug hunting, adding documentation and making sure we are able to cross-compile on Windows, MacOS, and Linux.
One thing that sets us apart from other initiatives is our openness to change, and to the whole management process of the library in general. We’re really happy to be part of a very exciting community, which seems to be continuously growing by the minute. So, check PCL out, and please let us know what’s wrong with it, so we can fix it!
Done!!!Willow Garage proudly presents the first open source “beer fetching app” for robots!
Part of a 1-week project, together with a few of my colleagues, we programmed the PR2 robot to:
navigate and find a refrigerator
open its door by locating the fridge handle
position the robot’s manipulators so that the door doesn’t close while grasping things inside the fridge
automatically identify the types of beer available in the fridge (we trained models on about 9 beers - training involves simply storing a picture of the beer bottle you want to identify in a directory)
determine the types of beer the user selected from a web page, compute grasping points, move the arms and grasp them, and then move the beers onto a storing rack that we installed on the robot
close the fridge door
navigate the the delivery point selected by the user on the web page
identify people faces and perform delivery/hand-off beer + bottle opener
