| 摘 要： | 由于镜头制造工艺的限制和拍摄条件及环境的影响,影像本身都存在或多或少的畸变误差,这种误差通过传播和累积给影像的后期处理及各种应用造成了不稳定因素。针对计算机立体视觉中基本矩阵的估计精度问题进行了深入研究,通过对相机非线性畸变的自动纠正,分别获取了校正前和校正后的基本矩阵。实验数据表明,在对影像进行畸变校正后估计出来的基本矩阵在平均核线距离和平均余差上都明显小于畸变校正前的。

| Abstract: | Because of the limits of camera manufacturing craftwork and the influence of photographic conditions and environments,the distortion error of image exists more or less.It brings the instable factors to the late image processing and applications through propagating and accumulating.The precision of estimation of fundamental matrix in computer stereo vision has been researched deeply,and the fundamental matrix of distorting images and un-distorting images was calculated respectively through correcting camera ... |
