J4K Java Library The J4K library is a popular open source Java library that implements a Java binding for the Microsoft's Kinect SDK.It communicates with a native Windows library, which handles the depth, color, infrared, and skeleton streams of the Kinect using the Java Native Interface (JNI). The J4K library is compatible with all kinect devices (Kinect for Windows, Kinect for XBOX, new. Install Kinect for Windows Runtime 2.0. Install Kinect for Windows SDK 2.0. Restart your PC. Once you have completed these steps, you can open the camera app on Windows 10 to verify that. If this is also your case and you installed the latest version of Kinect for Windows SDK (version 2.0), try the following: Unplug the Kinect from the USB 3.0 port; Remove the version 2.0 software (It is advisable though I didn’t remove it from my computer) Install the previous version of Kinect for Windows SDK (version 1.8).

Abstract

Body joint estimation from a single vision system poses limitations in the cases of occlusion and illumination changes, while current motion capture (MOCAP) systems may be expensive. This synchronized Azure Kinect-based MOCAP system serves as a remedy to both of these problems by creating a low-cost, portable, accurate body-tracking system.

Keywords: Motion capture (MOCAP) system, synchronization, Kinect, body-tracking

Demo

Check out the outcomes on some various movements!Note: this demo experiences some offset due to a parallax problem (devices are at a lower height than the human).

Building

Test Setup

Configuration

Daisy-chain configuration: supports connection of 2+ subordinate mode devices to a single master mode device (RS-232)

Testing Environment

Camera Calibration to capture synchronous images

Outcomes

Kinect Sdk 1.8

With multiple devices in place, joint estimation is still performed as if there is no occlusion or lighting effect.The following videos and images are tested in the test setup shown above.

Azure Kinect SDK Details

Azure Kinect SDK is a cross platform (Linux and Windows) user mode SDK to read data from your Azure Kinect device.

The Azure Kinect SDK enables you to get the most out of your Azure Kinect camera. Features include:

Depth camera access
RGB camera access and control (e.g. exposure and white balance)
Motion sensor (gyroscope and accelerometer) access
Synchronized Depth-RGB camera streaming with configurable delay between cameras
External device synchronization control with configurable delay offset between devices
Camera frame meta-data access for image resolution, timestamp and temperature
Device calibration data access
