The linear multi-baseline stereo system introduced by the CMU-RI group has been proven to be a very effective and robust stereovision system. However, most traditional stereo rectification algorithms are all designed for binocular stereovision system, and so, cannot be applied to a linear multi-baseline system. This paper presents a simple and intuitional method that can simultaneously rectify all the cameras in a linear multi-baseline system. Instead of using the general 8-parameter homography transform, a two-step virtual rotation method is applied for rectification, which results in a more specific transform that has only 3 parameters, and more stability. Experimental results for real stereo images showed the presented method is efficient. 相似文献

INTRODUCTION Stereo rectification is a crucial processing forany practical stereovision system; and is aimedtransform images so that the conjugate epipolarlines are aligned horizontally and in parallel. Variedand numerous rectification algorithms have beengiven in literature (Ayache and Lustman, 1991;Fusiello et al., 2000; Hartley, 1999; Robert et al.,1995; Mulligan and Kaniilidis, 2000; Isgro andTrucco, 1999). Most of them involve applying ahomography transformation for that purpose. … 相似文献

排序是最基础的算法之一,它应用极为广泛,应用于各个领域,不仅是数据库的核心技术,它本身也有广泛的应用场合。我们采用了分块排序、并归执行的算法,这样通过并发多个进程进行排序,通过对进程的同步的控制,合理的在内存中分配读进程和写进程,减少cpu与硬件的冲突,提高了效率。 相似文献

Neural network and genetic algorithm based global path planning in a static environment 总被引：3，自引：0，他引：3
INTRODUCTION The path planning problem of a mobile robot is to find a safe and efficient path for the robot, given a start location, a goal location and a set of obstacles distributed in a workspace. The robot can go from the start location to the goal location without colliding with any obstacle along the path. In addition to the fundamental problem, we also try to find a way to optimize the plan, say to minimize the time required or distance traveled (Wu et al., 1996; Sadati and Ta-he… 相似文献
