BTS Bioengineering

BTS Smart DX

High-end motion capture technology that is used by NASA?  What’s it doing it doing in my local bike shop?  Let’s explore what these funny-looking BTS cameras do and how they’ll make your bike fitting experience that much greater.

Main features – BTS Smart DX

  • High frequency acquisition up to 2000Hz
  • Resolution up to 2048×2048 pixels
  • Automatic marker identification
  • Quick calibration of multiple and with different dimensions volumes
  • Functioning without any loss of precision and accuracy.

Okay, so what do the factoids mean to you and what do they have to do with bike fitting?  Well these features allow us to create three dimensional renderings of your body in motion while you cycle.  High frequency acquistion gives the rendering a smooth look by collecting data (in this case images).  The high resolution means that we can zoom in and investigate problem area with without losing picture quality.  The software automatically picks up the markers we place at your joints and other significant points(the markers are reflective balls like they use in movies for motion capture).  Our system and software allow us to use multiple cameras, which creates a three dimensional box with a wire -frame verison of you cycling.  We can then manipulate the box so that we can look at your rendering from any direction.
