1. A method of determining multi-dimensional (mD) performance attributes of an in-the-field and moving sports participant who, at least at certain times routinely hovers about a predetermined hovering area while participating in a live in-the-field sports event, where the mD performance attributes are ones mapped along a time line as well as over a plurality of spatial reference coordinates and where the moving sports participant has a plurality of identifiable body parts, the method comprising:

  • receiving and recording at least first and second two-dimensional (2D) images of the moving sports participant from respective at least first and second high speed cameras, where each of the at least first and second cameras operates at more than 30 frames per second and where the respective at least first and second cameras are respectively pointed to have different points of view of the predetermined hovering area; and

    determining from at least two of the received and recorded 2D images, a multi-dimensional (mD) smooth and continuous motion curve of a selected one of the identifiable body parts of the moving sports participant, the multi-dimensional (mD) motion curve covering a continuous segment of time in which the moving sports participant was performing an in-the-field play action.
