摘要

Students at Rice University (Houston, TX, USA; www.rice.edu) have developed a vision-based tool that can be used for the qualita- tive analysis of a baseball pitcher's grip. Although grip is an essential part of pitching technique, current video-based analysis does not provide detailed grip information. Thus a method was required to discover the exact position and force of the pitching hand with respect to the ball during the process. The so-called Pitch Pressure Analysis and Logging System, or PitchPALS, developed at Rice employs a baseball that contains 28 piezoelectric sensors placed along the seams of the ball.
