Three cameras are set up in different positions, each seeing a slightly different view. Two cameras are considered the minimum for three-dimensional analysis. By adding a third camera, the accuracy of the data collection is increased. |

The following pictures show the action in all three cameras. The pictures on the left is what the cameras see. The pictures on the right is what the computer "sees" after it has tracked the image. To view a video of the motion, click on one of the links below each image. |

You will see that in the videos on the right, various markers are missing and some of the motion appears choppy. This is because the data is in the '"raw" form. The analysis software will compare the three camera views, and construct a three- dimensional representation of the musician. To to this, complex mathematical equations are required. |

A useful application is the ability to overlay the computer-generated stick figure on top of the original video footage. Here the subtleties of the interrelated motions of the arm and bow can be more clearly seen. A further step would be to render a computer-animated virtual bow arm capable of being rotated and being seen from any perspective. |
