動画像からの移動物体の抽出と速度推定

Abstract

This study aims at speed estimation of a moving object from pictures photographed with a digital camera. The background subtraction method was used to recognize a moving object. In addition, the recognition rate is improved with a median filter and noise elimination by pixel and line matching. Speed estimation was performed with comparing positions of the gravity of the object in two different pictures. Speed estimation is achieved with the accuracy of ±1%.
