侦测多移动目标之方法;METHOD OF DETECTING MULTIPLE MOVING OBJECTS

摘要

本发明系揭露一种侦测多移动目标之方法，其包含下列步骤：寻找影像序列中之特征点，利用多视角几何(multiple view geometry)将特征点分成前景型与背景型；利用背景特征点计算出透视变换矩阵(perspective transform matrix)以找出背景运动，藉由透视变换矩阵建立新影像与当前影像之差值，及得到移动目标的轮廓；藉由移动历史及型态学处理以取得各移动目标之轮廓，并以方框追踪各移动目标。; computing perspective transform matrix for estimating the motion of background by the feature points of background, and generating contours of moving targets by the difference between the current image and a new image established by perspective transform matrix; extracting the contour of the each moving object by motion history and morphological processing, and tracking the each moving object with a bounding box.
