WIPO Patent Application WO/2002/077653
Kind Code:
A1
Abstract:
A mobile measuring device, comprising cameras (2) for photographing a swimmer (9) swimming in a pool (10) from just above the swimmer and a control part (8) for calculating the moving speed of the swimmer (9) based on the images photographed by the cameras (2), whereby, by photographing the swimmer (9) from just above the swimmer, the portion of the swimmer (9) to be measured can be prevented from being hidden by the rotation of the arm of the swimmer (9) and the resulting spraying of water and water bubbles, the position of the swimmer (9) for each unit time can be detected accurately based on the photographed images, and the moving speed of the swimmer can be measured continuously.
