The ROS driver publishes point clouds, depth, ir and noise images through ROS topics, supports dynamic reconfigure, nodelets with zero copy transfers and comes with a fully configurable launch file and a detailed readme.

The sources can be found on our GitHub:

  https://github.com/code-iai/pico_flexx_driver

Information on the device itself can be found here:
http://www.pmdtec.com/picoflexx/

Some device features:
- size: 68 x 17 x 7.25 mm (WxHxD)
- measurement range: 0.1 - 4 m
- FPS: 5 to 45
- resolution: 224 x 171

Rhoeby Dynamics R2D LiDAR

From John Jordan President of Rhoeby Dynamics LLC

The new Rhoeby Dynamics R2D LiDAR is the smallest, lightest, lowest-cost
2D LiDAR device on the market today. It's proven capable of performing
mapping, navigation and dynamic obstacle avoidance in the indoor setting,
and comes complete with its open-source ROS driver for rapid integration
into any robotics platform.

The device uses IR LED Time-of-Flight (not laser-based), making it a quite
novel technology. This novel approach is what enables us to achieve the
small form factor, low weight, and helps keep the cost down. All settings
are easily controlled via USB (or UART).

Video demonstrations of the LiDAR in operation can be seen here:

    http://rhoeby.com/video

In summary, the LiDAR has the following features:

    * Scan rate: up to 5 Hz, user-configurable
    * Scan range: 360 degrees, over 5 meters
    * Angular resolution: typically ~ 1.0 degree, maximum 0.36 degrees (@
1 Hz scan rate)

    * small form-factor (75 x 45 x 45 mm)
    * light-weight (< 125 g)
    * robust design (direct-drive motor)
    * no safety issues (compared to laser-based device)

We're confident that this device is well-suited to cost-sensitive
applications requiring indoor Simultaneous Localization And Mapping
(SLAM), navigation and obstacle avoidance, and will be a good fit for many
robots. The device is available now, for immediate delivery in the United
States and beyond.

ROS package for Basler cameras

| No Comments | No TrackBacks
From Beatriz Leon Pinzon via ros-users@

We have created a ROS package to be able to publish images using a Basler camera. We have a Basler Dart camera but the package should work with any of their cameras as all use the same API.

Here is the github address:
https://github.com/shadow-robot/basler_camera

Their cameras are not yet uvc compatible so this package would be helpful in the meantime.

Real-time stereo vision integration into ROS

From Konstantin Schauwecker via ros-users@

I'm glad to announce the ROS integration of the SP1 stereo vision system by Nerian Vision Technologies. The SP1 provides real-time 3D data through the use of a stereo camera and a powerful FPGA. In ROS, this data can be published as a point cloud or as a disparity map.

You can find the wiki page for the ROS node here:
http://wiki.ros.org/nerian_sp1

Further information about the SP1 system can be found on the product page:
http://nerian.com/products/sp1-stereo-vision/

The ROS node and the API code are published under the MIT license, and can thus be freely modified and redistributed.
From Konstantin Zhukov via ros-users@

I'd like to announce OrSens - portable stereo-camera calculating depthmap onboard, so you can get depth and RGB streams via USB at 30FPS.

Here is the ROS wiki page for more info:


Here are the repositories:


Here's the website:

Our team is working on deep integration with ROS and on providing some ready-to-use computer vision solutions.
We ourselves use the camera in our device for blind people, with ROS-powered software.

We hope that our work could be useful for the community.

Cross posted from: Ros-Industrial


Love Park Robotics has announced a ROS driver for the new IFM Efector O3D303 3D camera system. This sensor was officially released in Germany on April 13, 2015. The O3D303 is a time-of-flight sensor, specifically designed for use in industrial environments and automation applications. The 176x132 element detector features a relative accuracy of +/-4mm. In addition to the robust design, it is able to operate in illumination conditions ranging from complete darkness to sunlight. It is also affordable, at a per-unit cost of $1250 USD. A picture of the O3D303 is shown below along with a point cloud of an imaged pallet (taken in an office environment) to highlight the quality of the sensor data.

As part of our beta test period, Love Park Robotics developed a software interface to the O3D303 that allows us to utilize the sensor within software frameworks such as PCL, OpenCV, and ROS. This code has been made available as open-source on Github in the following repositories: libo3d3xx and o3d3xx-ros. Additionally, we are working with the ROS Industrial community to make binary debian packages available as part of the core ROS and ROS-I distributions.

New driver for DepthSense DS325 3D Camera

| No Comments | No TrackBacks
From Walter Lucetti via ros-users@

if someone is searching for a driver for the DepthSense DS325 RGB-D time-to-flight camera, I'm glad to say that the first working version of it is available on Github:

https://github.com/Myzhar/ros_depthsense_camera

At this stage the driver can correctly publish RGB videostream, Simple XYZ Pointcloud and RGB XYZ Pointcloud.

One of the strenght of my driver is the fact that it does not use neither OpenCV nor PCL libraries.
It publishes only  sensor_msg::pointcloud2 and sensor_msg::Image messages.

The next step will be the porting on CUDA of the heaviest function like the RGB to XYZ mapping and the use of the builtin accelerometer to compensate robot asset.
I will also write the code to simulate a 2D laser scanner to provide full information... if requested.

All this with an eye on the use of 100% of the potential of NVidia Jetson TK1...

Any comment or debug will be really appreciated

DUO3D ROS node release

| No Comments | No TrackBacks
From Krystian Gebis via ros-users@

Hello all,

Recently, I have been working on creating a ROS driver for the DUO3D camera. After working with the DUO team, I have managed to wrap ROS around the DUO API functions, and have the camera images be published as ROS messages' of type sensor_msgs::Image. For those of you who do not know about DUO3D, it is a new, relatively inexpensive, stereoscopic camera which allows for many different custom solutions such as better lens, wider baseline, etc. More information about DUO3D can be viewed here: https://duo3d.com/ . 

For those of you who are interested, here is a link to the github repository where I have developed the duo3d_camera node: https://github.com/l0g1x/DUO-Camera-ROS

As for now, I am still in the process of talking with DUO on how to package their shared libraries into a Debian package, so once I get that figured out with them, I will try to release the first version to the ROS repo.

I welcome everyone to give me feedback, as this is my first contribution back to the ROS community.

Announcing ROS support for LazeeEye

| No Comments | No TrackBacks
From Heuristic Labs via ros-users@

I'm writing to make you aware of an exciting new Kickstarter project, the "LazeeEye": http://kck.st/1gVCcrB

lazeePi.jpg

LazeeEye takes your existing smartphone and turns it into a depth camera using laser illuminator hardware and a stereo vision processing app. 

The goal is to produce hardware and software that can bring 3D perception to devices that have low-power/low-weight processing and a high-resolution, such as what you would find in your smartphone.

You as a ROS user can be particularly excited about using your existing smartphone in robotics applications. In fact, the inspiration for the LazeeEye was for lightweight aerial robots, where we were constrained by the redundancy, inefficiency, cost, and lack of portability of existing 3D sensors.

For more information, or to consider supporting the project, please check out the Kickstarter page: http://kck.st/1gVCcrB, and don't hesitate to spread the word!

I just wanted to affirm that ROS drivers will be made available for LazeeEye, including image capture through rosjava (if on Android). We'll make every attempt possible to match existing conventions for the RGB-D processing pipeline, so as to seamlessly replace your legacy Kinects and Xtions : )

Also wanted to mention hardware support for LazeePi (LazeeEye on a Raspberry Pi), and its camera module.
