Qualisys-Python-IO 0.0.3

A python packege to get data from qualisys cameras

qualisys_python_IO

This repository provides an interface for connecting to and interacting with a Qualisys Motion Capture system. The main components include a Python class for handling the connection and data retrieval, and supporting functions for processing the motion capture data.

Files

1. qualisys_io.py
   • Purpose: Manages the connection to the Qualisys system and handles the retrieval of position and rotation data.
   • Key Classes/Methods:
     • qualisys_io: Initializes the connection, starts/stops the data stream, and retrieves position and rotation data.
     • connect(): Starts the data streaming process.
     • stop(): Stops the data streaming and disconnects from the system.
     • get_position_rotation(): Retrieves the latest position and rotation data from the Qualisys system.
2. lib.py
   • Purpose: Contains the underlying logic to connect to the Qualisys system and process 6DoF data.
   • Key Functions:
     • run(): Main loop to handle the real-time data processing and streaming.
     • create_body_index(): Parses the XML data to create a dictionary mapping body names to indices.
     • body_enabled_count(): Counts the number of enabled 6DoF bodies.
     • main(): Handles the connection to the Qualisys system, retrieves data, and processes it in real-time.

How to Use

example:

import time
from Qualisys_Python_IO import qualisys_tools

robo_position = qualisys_tools.qualisys_io("Robo01","192.168.0.26","password")

robo_position.connect()
time.sleep(1)
position,rotation = robo_position.get_position_rotation()
print(position,"\n",rotation)

robo_position.stop()
