 ====== AMASS Overview ======
-AMASS (**A**DTech **M**otion **A**nalysis **S**oftware **S**ystem) is a software package for deriving the three-dimensional (3D) locations of passive targets (unidentified markers) imaged by any number of video cameras, and writing the identified data to file using the [[[http://www.c3d.org|C3D file format]]]. Input data are the marker centroids expressed in each camera’s image coordinate system, and a small number of parameters. The full AMASS software and documentation is available as a free download for evaluation purposes, but a wand must be purchased if you wish to use AMASS within your application.

 In the current context we restrict ourselves to imaging and extracting 3D information on “points”, and do not include surfaces or volumes unless they may be constructed from a multitude of “points”. Physically every “point” has a finite extent and is usually defined by the location of a marker (or target). Typically markers are spherical for optimal accuracy but that is not a requirement, as for example with systems that use active markers (LEDs).

 ==== A little history ====
-The original AMASS was released in 1988 and presented novel solutions to issues such as camera lens distortions, camera system calibration, image data reduction, and integrated 2D and 3D marker tracking. It also introduced the [[[http://www.c3d.org|C3D file format]]] for identified 3D marker data that has become a standard for biomechanical applications, see [[[http://www.c3d.org|c3d.org]]]. In 1995 AMASS introduced the first wand calibration that has now become the standard for passive marker systems. Since that time, computer, camera, and software technology has grown at a rapid pace to the point where an inexpensive desktop computer and off-the-shelf cameras can easily collect and process data from many cameras and create extremely large data files.

 Unfortunately the ease-of-use of 3D measurement systems has not kept pace with hardware improvements, with the consequence that many commercial systems still have a steep learning curve and often require dedicated professionals for their effective operation. The reason for this is twofold:
