Bow-arrow interaction in archery.
A mathematical model of the flight of the arrow during its discharge from a bow was proposed by Pekalski (1990). His description of the model was incomplete. In this paper, I give a full description of the model. Furthermore, I propose some improvements that make his model more consistent with reality. One achievement is the modelling of contact of the arrow and grip; the pressure button is mod...
متن کاملMathematical and Computer Model of Sport Archery Bow and Arrow Interaction
The aim of the research was to summarize a mathematical model of bow and arrow interaction in the vertical plane and to develop an appropriated computer model. A bow was modeled as a non-deformed riser and hinged to it two nondeformed limbs with Archimedean springs. Their stiffness as well, as an elasticity of a string was taken into account in a linear approach. An asymmetric bow scheme was co...
متن کاملA three-dimensional analysis of finger and bow string movements during the release in archery.
The aim of this paper was to examine finger and bow string movements during archery by investigating a top Austrian athlete (FITA score = 1233) under laboratory conditions. Maximum lateral bow string deflection and angular displacements for index, third, and ring fingers between the full draw position and the end of the release were quantified using a motion tracking system. Stepwise multiple r...
متن کاملDesign and Virtual Studio Presentation of a Traditional Archery Simulator
In this paper we describe the design of a virtual reality simulator for traditional intuitive archery. Traditional archers aim without a target figure. Good shooting results require an excellent body-eye coordination that allows the user to perform identical movements when drawing the bow. Our simulator provides a virtual archery experience and supports the user to learn and practice the motion...
متن کاملArrowsmith: 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...
