摘要
Scientific recording of motion and providing feedback based on the evaluation of the recorded data is an essential element of sport science. Today, motion analysis in sports can only be performed in a laboratory environment. In that case, fine differences specific to sports are lost and limited information can be achieved regarding the factors that bring success. The idea of performing motion analysis in sports by recording motions using digital video cameras and evaluating the recorded images through photogrammetric methods is a current issue in sport science. The aim of the present study was to describe a new photogrammetric method used in the analysis of sport movements. For this purpose, images were obtained using two 200 FPS+VGA+1394B Dragonfly Express video cameras. A calibration cage was used while recording the images. Afterwards, the recorded images were evaluated using Pictran, which is a software package for the photogrammetric evaluation of digital images.
