Overview of this book

Kinect has been a game-changer in the world of motion games and applications since its first release. It has been touted as a controller for Microsoft Xbox but is much more than that. The developer version of Kinect, Kinect for Windows SDK, provides developers with the tools to develop applications that run on Windows. You can use this to develop applications that make interaction with your computer hands-free. This book focuses on developing applications using the Kinect for Windows SDK. It is a complete end to end solution using different features of Kinect for Windows SDK with step by step guidance. The book will also help you develop motion sensitive and speech recognition enabled applications. You will also learn about building application using multiple Kinects.The book begins with explaining the different components of Kinect and then moves into to the setting up the device and getting thedevelopment environment ready. You will be surprised at how quickly the book takes you through the details of Kinect APIs. You will use NUI to use the Kinect for Natural Inputs like skeleton tracking, sensing, speech recognizing. You will capture different types of stream, and images, handle stream event, and capture frame. Kinect device contains a motorized tilt to control sensor angles, you will learn how to adjust it automatically. The last part of the book teaches you how to build application using multiple Kinects and discuss how Kinect can be used to integrate with other devices such as Windows Phone and microcontroller.

Depth data and distance


The depth vision for the Kinect sensor ranges from around 800 mm to approximately 4000 mm (2.6 feet to 13.1 feet), which is the default range for the depth stream. However, the sensor can capture the information beyond 4000 mm, in which case the quality of data will be compromised as the sensor is not built for that.

Note

The DepthImageStream and DepthImageFrame classes have the MaxDepth and MinDepth properties, which return the maximum and minimum depth ranges for that particular stream or captured image frame, in millimeters. This range value returns the best range where distance can be measured properly. Keep in mind, these are read-only properties; these values will change automatically based on the selection of DepthRange for the stream.

The following image shows the default depth range for a Kinect sensor where the sensor can track the objects and measure the distances:

The Kinect depth sensor calculates distance based on the straight distance between the object...
