Measuring ice hockey shot accuracy with precision: a 3d puck flight simulation

This study aimed to develop a model to predict ice hockey shot puck trajectory based on the initial puck launch vectors and aerodynamic variables. Using motion capture data collected from wrist and slap shots executed within an ice arena, a puck’s position and orientation was tracked from release to an end target location. These data were used to assess the model’s ability to predict puck trajectory from initial launch vectors. Preliminary data showed that for shots executed 10m from the target, the model had a mean RMS error within 1.85 cm laterally and 4.91 cm vertically; both were less than a puck’s diameter. With further refinements, we aim to improve the model’s accuracy. Ultimately, players and coaches may use these predictive models as a training tool to evaluate player shot accuracy both on ice and in smaller off ice training facilities.
