azure kinect dataset

Question

can anyone please provide me with body movement dataset from azure Kinect so i can analysis this data

Answer 1

Hi Ahmed, thank you for posting the question. There are no recorded Data sets available on the Azure Kinect DK documentation that we can share with you on this.

However, there is a quickstart on Record Azure Kinect sensor streams to a file that lets you save the sensor streams and output to an .mkv file. Once you have the file generated, there are tools in place that lets you extract the data from the .mkv file to different formats.

To record sensor data, the Matroska (.mkv) container format is used, which allows for multiple tracks to be stored using a wide range of codecs. The recording file contains tracks for storing Color, Depth, IR images, and IMU.

Low-level details of the .mkv container format can be found on the Matroska Website.

Tools such as ffmpeg or the mkvinfo command from the MKVToolNix toolkit can be used to view and extract information from recording files.

For example, the following command will extract the depth track as a sequence of 16-bit PNGs to the same folder:

Copy

ffmpeg -i output.mkv -map 0:1 -vsync 0 depth%04d.png

The -map 0:1 parameter will extract track index 1, which for most recordings will be depth. If the recording doesn't contain a color track, -map 0:0 would be used.

The -vsync 0 parameter forces ffmpeg to extract frames as-is instead of trying to match a framerate of 30 fps, 15 fps, or 5 fps.

Please refer the resource Record File Format to get more information on the options available.

Hi,

There are several publicly available datasets that include body movement data from Azure Kinect DK:

1. Azure Kinect Body Tracking SDK samples: Microsoft provides several samples with the Azure Kinect Body Tracking SDK, which include body movement data. You can download the SDK from the Microsoft website and find the samples in the C:\Program Files\Azure Kinect Body Tracking SDK\sdk\windows-desktop\amd64\release\samples_c directory.
2. CMU Panoptic Dataset: This dataset includes a variety of visual data including body movements captured by the Azure Kinect DK. You can access the dataset at https://domedb.perception.cs.cmu.edu/index.html.
3. Azure Kinect ROS Driver: The ROS driver for Azure Kinect includes body tracking data in its output. You can find information about the driver and the ROS packages at https://github.com/microsoft/Azure_Kinect_ROS_Driver.

Note that these datasets may require some processing and cleaning before they can be used for analysis. Additionally, make sure to check the terms of use for each dataset to ensure that you are using it in compliance with any restrictions or requirements.
