Arrowsmith: Automatic Archery Scorer
We present a method for automatically determining the score of a round of arrows lodged in an archery target face. That is, given an image consisting of a complete target face, and given a set of arrows that have struck within the target face, we generate a score for each arrow with regard to which two circles it’s between. To do this, we present a multi-step process to determine the location a...
متن کاملApplications of Physics to Archery
Archery lends itself to scientific analysis. In this paper we discuss physics laws that relate to the mechanics of bow and arrow, to the shooting process and to the flight of the arrow. In parallel, we describe experiments that address these laws. The detailed results of these measurements, performed with a specific bow and arrow, provide insight into many aspects of archery and illustrate the ...

One achievement is the modelling of contact of the arrow and grip; the pressure button is mod...
