- Abstract
- Sports arcade games use a ball simulator to predict the trajectory of a flying ball with initial conditions, including ball speed and spin. Therefore, the accurate measurement of initial conditions of a flying ball is a critical issue for sports arcade games. In usual, high-tech equipment, such as Doppler radars and high-speed video cameras, is used for commercial sports arcade game systems. However, such high-tech equipment increases the system cost for developing sports arcade games. Multi-exposure cameras can be adopted for sports arcade games instead of using such high-tech, high-cost equipment. A golf game system with multi-exposure cameras has been introduced in the related work [Kim and Kim 2012]. In this paper, a new approach for measuring initial conditions of a pitched baseball with multi-exposure cameras is presented for baseball pitching games. The new approach can robustly detect baseball regions and surface patterns to measure initial conditions with high accuracy regardless of illumination conditions. 2013 Copyright held by the Owner/Author.
