【摘要】 为了精确地预测出做单摆运动的物体在下一时刻的位置,提出一种基于双目视觉的确定物体位置并预测运动轨迹的方法。通过标定、图像预处理、目标捕捉、特征匹配以及三维重建等步骤可以较为准确地获得运动物体在一段时间间隔内的位置坐标。本实验采用多项式拟合运动轨迹,根据双目摄像机测定的历史位置坐标代入多项式中从而预测出下一时刻运动物体的位置。实验结果表明,该方法能够快速计算运动物体的位置坐标并能够准确地预测出下一时刻位置坐标,具有很高的通用性和灵活性。更多还原

【Abstract】 In order to obtain the trajectory accurately and predict the position at the next moment,a method based on binocular vision is proposed in this paper. By the steps of calibration,image preprocessing,target capture,feature matching and 3D reconstruction,the position coordinates of a moving object in a period of time can be obtained more accurately. In this experiment,according to the binocular camera’s historical position coordinates,the position of the moving object is predicted at the next moment. The experimental results show that the proposed method can quickly calculate the position coordinates of the moving objects and can accurately predict the position coordinates of the next time,which has high generality and flexibility.更多还原
