摘要
随着计算机技术、数字信号处理理论和视觉传感技术的发展,人们开始了视觉定位技术的研究;为实现精准、快速的定位效果,阐述了以块匹配法为核心,基于序列图像的室内定位算法;首先初始化序列图像,然后确定搜索区域,计算最小绝对差,返回图像的坐标值,进行坐标变换,最终计算得出两帧图像的位置变化;实验结果表明,经过算法处理的移动轨迹可以近似地表示定位目标的实际路径。
As the development of computer technology, digital signal processing and vision sensing, people start to research the technol- ogy of visual position. In order to achieve the result of exact and quick positioning, describe indoor position algorithm on block match of image sequence. First, initialize the image sequence, and then define search area, compute the MAD, return the coordinates of image, transform the coordinates, at last, get the change of two images. Experimental results show that the mobile track by algorithm can represent the actual path approximately.
