Kinect python tutorial

The kinect is an amazing and intelligent piece of hardware. The RGB camera is like any other camera such as a webcam but it is the depth sensor that the Kinect is known for as it enables the Kinect to perceive the world around it in 3D! Note :- This tutorial assumes that you have Linux Ubuntu or Ubuntu based Linux distro with opencv installed on your system. Run the following command in a terminal to test if libfreenect is correctly installed.

This should cause a window to pop up showing the depth and RGB images. Before doing that, install the necessary dependencies. You are commenting using your WordPress. You are commenting using your Google account.

Or if you know a bit about development with the Kinect 2 already, you can skip to a particular lab by navigating to it at the top of the page. The running codebase is available through a link at the bottom of each page, which is complete and runnable as if you have just finished that lab.

If you have any suggestions or would like to report any bugs, please leave some feedback on the Kinect Tutorial GitHub Issues page. Enjoy the labs and have fun! System Requirements The target application is a Windows 8. Supported Operating Systems and Architectures. Debugging the Kinect 2 requires that you meet the system requirements. If you are unsure that the Kinect is plugged in properlyyou can check a light indicator on the power box of the unit the box which comes from the single cable in the Kinect 2 and results in power and USB 3.

If the light on the power-box is Orange then something is wrong with either the power, Kinect 2, or USB3. If the light is White then the Kinect is correctly registered with windows as a device to be used.

The Kinect 2.Goals: Learn how to align color and depth images to get a colored point cloud. The most interesting part is that now we're working with 3D data! Creating an interactive system is a bit too much code for us, though, so we just have a simple rotating point cloud. This tutorial has three parts: first, we'll talk briefly about why point clouds are harder than you might think. Then, we'll show the Kinect SDK side of how to get the right data.

Finally, we'll show some OpenGL tricks to make things easy to display. The positive Y axis points up, the positive Z axis points where the Kinect is pointing, and the positive X axis is to the left. Alignment A naive way of making a point cloud might directly overlap the depth and color images, so that depth pixel x,y goes with image pixel x,y. However, this would give you a poor quality depth map, where the borders of objects don't line up with the colors.

This occurs because the RGB camera and the depth camera are located at different spots on the Kinect; obviously, then, they aren't seeing the same things!

Normally, we'd have to do some kind of alignment of the two cameras the formal term is registration to be able to map from one coordinate space to the other. Fortunately Microsoft has already done this for us, so all we need to do is call the right functions.

Kinect Code A lot of this is just combining the code from the first two tutorials. Kinect Initialization There's nothing new in initialization. We simply need two image streams, one for depth and one for color. We'll store this information in another global array, depthToRgbMap. In particular, we store the column and row i. Now that we're dealing with 3D data, we want to imagine the depth frame as a bunch of points in space rather than a x image.

So in our getDepthData function, we will fill in our buffer with the coordinates of each point instead of the depth at each pixel. Vector4 is Microsoft's 3D point type in homogeneous coordinates. If your linear algebra is rusty, don't worry about homogeneous coordinates - just treat it as a 3D point with x,y,z coordinates. This is in the Kinect-based coordinate system as described above. There is also a version of this function that takes an additional resolution argument. NuiImageGetColorPixelCoordinatesFromDepthPixelAtResolution is takes the depth pixel row, column, and depth in the depth image and gives the row and column of the pixel in the color image.Notice : MediaWiki has been updated.

Report any rough edges to marcan marcan. This page documents how to get started using OpenKinect. The libraries are very much in flux and this won't be the final process. This also means these instructions might be out of date with the latest commits. You may also want to take a look at the following for more information:. For support requests in the OpenKinect irc channel or in the mailing list, please specify the platform you are using, the version of the software you are trying to build or install, and information about the context etc.

The Kinect needs its own power source which is independent from the USB connection to work on a computer. The latest Xbox can power the Kinect directly but the older Xbox requires an adapter for that purpose.

Therefore, the Kinect which is bundled with the Xbox doesn't include an adapter whereas the Kinect which is sold separately does. The adapter is sold here.

The freenect device is accessible to any user belonging to the group 'plugdev'. By default, a desktop user belongs to the plugdev group but if you need to add them to the group:. If you want a recent version of libfreenect no matter which version of Debian or Ubuntu you use, backports of the latest release of libfreenect for all supported version of Debian and Ubuntu namely Ubuntu Lucid Make sure your user belongs to the plugdev group The default for a desktop user to access the device without the root privileges.

If it is not the case, add them by:. An Ubuntu launchpad ppa for Lucid After that, you need to add yourself to the 'video' group and log back in. The package already includes the necessary rules for the udev daemon so that accessing the device will be possible for users in the group video. You don't need to reboot, just plug in the kinect device right now if it was already connected, unplug and plug back in. If you can't access or still need root privileges to use your device: in some cases there might be conflicts between permissions of two drivers installed libfreenect and primesense.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

It's great fun to play on it, So, I was wondering if it was possible to use Python to use it and make my own games and play on PC. Currently, I have 1. Drivers from Microsoft and the hardware. No experience with 3d programming. My Questions 1. Is there good and easy to use module for using Kinect on PC??

And any books for the same?? There is a project called Open Kinect which has many wrappers that you can make use of, including one for Python. To help you get started, there are a good few code demo's supplied with their source code, which can also be viewed online here. Once you've got to grips with making use of the information the Kinect is sending back to you, you can try the popular pygame to base a game around whatever it is you're trying to do.

If not, Python interpreter may think some of the path as character encoding. The main site for PyKinect can be found here. Check it out before jumping in to a PyKinect project — it is worth getting a sense of the resources that are already available.

Download PythonToolsIntegrated. This installs all of the Python tools, not just PyKinect, but you can deal with those as you like. I also recommend downloading the Python Imaging Library for some image capture and manipulation and SciPy for heavy data processing. The challenge was how to make that happen. Here are the directions for posterity: 1.The Microsoft Kinect sensor is a peripheral device designed for XBox and windows PCs that functions much like a webcam.

However, in addition to providing an RGB image, it also provides a depth map. Meaning for every pixel seen by the sensor, the Kinect measures distance from the sensor. This makes a variety of computer vision problems like background removal, blob detection, and more easy and fun! The Kinect sensor itself only measures color and depth.

This library uses libfreenect and libfreenect2 open source drivers to access that data for Mac OS X windows support coming soon. OpenNI has features skeleton tracking, gesture recognition, etc. Unfortunately, OpenNI was recently purchased by Apple and, while I thought it was shut, down there appear to be some efforts to revive it!

If you want to install it manually download the most recent release and extract it in the libraries folder. Restart Processing, open up one of the examples in the examples folder and you are good to go! Processing is an open source programming language and environment for people who want to create images, animations, and interactions.

Initially developed to serve as a software sketchbook and to teach fundamentals of computer programming within a visual context, Processing also has evolved into a tool for generating finished professional work. Today, there are tens of thousands of students, artists, designers, researchers, and hobbyists who use Processing for learning, prototyping, and production. Currently, the library makes data available to you in five ways:.

If you want to use the Kinect just like a regular old webcam, you can access the video image as a PImage! You can simply ask for this image in drawhowever, if you can also use videoEvent to know when a new image is available. With kinect v1 cannot get both the video image and the IR image. They are both passed back via getVideoImage so whichever one was most recently enabled is the one you will get.

However, with the Kinect v2, they are both available as separate methods:. For the kinect v1, the raw depth values range between 0 andfor the kinect v2 the range is between 0 and For the color depth image, use kinect. Pixel XY in one image is not the same XY in an image from a camera an inch to the right.
