This chapter requires you to have a Microsoft Kinect 3D sensor installed. Alternatively, you may install an Asus Xtion sensor or any other depth sensor for which OpenCV has built-in support.

First, install OpenKinect and libfreenect from http://www.openkinect.org/wiki/Getting_Started. You can find the code that we present in this chapter at our GitHub repository: https://github.com/PacktPublishing/OpenCV-4-with-Python-Blueprints-Second-Edition/tree/master/chapter2.

Let's first plan the application we are going to create in this chapter.
