# Kinect Simple Body Tracking CSV Recorder
2+
3+
This is a tool that uses Azure kinect to record body tracking data to a CSV file.
4+
5+
## Usage
6+
7+
1. Install [Azure kinect Sensor SDK](https://learn.microsoft.com/en-us/azure/kinect-dk/sensor-sdk-download) and [Body Tracking SDK](https://learn.microsoft.com/en-us/azure/Kinect-dk/body-sdk-download).
8+
1. Download this tool. (→ [Release page](https://github.com/Hashory/kinectSimpleBodyTrackingCSVRecorder/releases))
9+
1. Run `kinectSimpleBodyTrackingCSVRecorder.exe`.
10+
11+
## CSV file format
12+
13+
The CSV file contains the following information.
14+
There are 32 joints in total, each with three coordinates (x, y, z). Therefore, there are 96 rows in total.
15+
See [here](https://learn.microsoft.com/en-us/azure/kinect-dk/body-joints#joint-hierarchy) for joint order and more information.
16+
17+
**CSV format:**
18+
```csv
19+
PELVIS.x, PELVIS.y, PELVIS.z, SPINE_NAVAL.x, ･･･ EAR_RIGHT.y, EAR_RIGHT.z
20+
```
21+
22+
Also, be careful with the coordinate system. Azure kinect uses [this](https://learn.microsoft.com/en-us/azure/kinect-dk/coordinate-systems#3d-coordinate-systems).
