Title:
ストローク情報計測装置
Document Type and Number:
Japanese Patent JP4234407
Kind Code:
B2
Abstract:
To provide a stroke information measuring apparatus capable of measuring stroke information with high precision, without tracking a specific part of a swimmer.
A swimmer 150 in action is photographed with an imaging means 2, and pixel data on a position corresponding to a specified instrumentation line out of individual acquired image data are extracted by the image extraction means of an arithmetic part 3. The pixel value of the extracted pixel is binarized and integrated by an integrating means. A transit time determination means determines instrumentation line transit time of the swimmer 150 from a time-series change in accumulated data, and sends it to a server section 5.
