Motion Capturing with Xsens



_

_

the case with all sensors and two suits

Case and Content

The case contains everything you need to capture full body performances. The two suits in the small bags are for different body sizes.

Sensors

Top row, ltr: upper body sensors, lower body sensors, prop. Bottom row, ltr: upper body cable whip, lower body cable whip, cable whip to connect prop in conjunction with a body part.

There should be 18 sensors in the case. These 17 are essential to get the capturing process started at all:

Upper Body: 1 x Head, 1 x Stern, 3 x Left Shoulder, 1 x Left Hand, 3 x Right Shoulder, 1 x Right Hand

Lower Body: 1 x Pelvis, 3 x Right Leg, 3 x Left Leg

Additional sensor: 1 x Prop.

The Sensors are connected to cable whips that should be contained in the same bag as the sensors.

Bodypack

The bodypack is a small computer that processes the information provided by the sensors.


Battery

The battery comes with a wrapper, a cable to connect it to the bodypack and a charger.


Router

The router is connected to a PC with an Ethernet Cable and sends the information it receives from the bodypack to the Xsens Mvn Software.


Dongle

The dongle is an authentification device that needs to be plugged into the PC to get the Xsens software running. You'll find the dongle right next to the bodypack.


Additional Accessories

There should be a tape measure as well inside of the case.

Dressing up

Using the right dimensions

This is how you put on the lycra suit.

So far we're offering two suits: L (1.60m - 1.75m) and XL (1.75m - 1.85m). You shouldn't put it on if you're larger than that.

Washing the suit

Due to hygienic reasons you must always wash the suit after using it. Remove all cables, Bodypack and Motiontrackers. Follow the instructions on the label inside the suit:

  • Only Synthetic machine wash at 30°C!!!
  • Do not bleach
  • Do not iron
  • Do not dry clean
  • Do not tumble dry
  • For the headband, gloves and straps use only cold hand wash.

Wiring things up


You can follow this instructional video to wire up the suit. Always have a second person to help you set things up.

Xsens Mvn FullBody Software

There is a lot of information about the Software and how to use it on their support page.

Installing the Software

Download MVN Analyze/Animate here.

Motion Capture Live Streaming

Connect the Router to your PC with an ethernet cable.

As soon as you're set up just activate the bodypack as depicted here. You should hear a double beep. Go to "File", and press "Start Motion Capture".

Turn on a user. All the working sensors should be depicted in green.

Body Dimensions


Insert the body dimensions of the user and save them for later re-use.

Calibration


Calibrate the body in order to have a proper looking performance.

Live Recording

You should be able to start live recording now.

External Software Link

Life Performances don't need to be limited to the Xsens Software. There are working realtime integrations with Maya, Motionbuilder, Unity and Unreal Engine.

Maya

Follow this link. Under "Plugins, Integrations and Sychronizations" you can download the latest Maya Plugin. Then just follow the procedure depicted in this video

Unreal Engine

There is a good documentation on how to set up the Xsens Suit with Unreal here

Unity Engine

OBR (On Body Recording)

OBR allows you to capture your movements anywhere.

Software Setup

Go to OBR and turn it on. Configure if you're going to be moving on uneven ground.
