Examples
- The main work of the thesis is as follows : we design a novel omni - mirror more applicable in robocup , which is made up of an isomeric horizontal mirror and an isomeric vertical mirror and can make the resolution of the imaging of the objects near the robot on the field constant and make the distortion of the imaging of the objects far from the robot small in vertical direction ; we select a 1394 digital color camera and complete the development of its software program for data acquisition ; we design a image processing algorithm for the panoramic image , which can segment the image by color , extract the features of image fast and effectively and complete the recognization of target ; according the character of the imaging , we design a new fast hough transform algorithm for line detection , which can detect the white mark lines of the field realtimely , and then design a robot ’ s self - localization method based the mark lines , which only uses the information of omni - vision system ; finally we design a monte carlo localization method based on the information of omni - vision system and odometry , and present the localization results of two localization methods and analyze the experiment results and get the conclusions
本论文的主要工作如下:设计了一种新的更适用于机器人足球赛的全向反射镜面,该镜面由水平等比镜面和垂直等比镜面组合而成,能够使机器人近处一定范围内水平场地上的物体成像分辨率不变,远处物体成像高度上变形较小;选择了一款基于1394接口的数字摄像机,并完成其数据采集程序开发;针对全景图像设计了图像处理算法,能够快速有效的实现图像颜色分割和图像特征提取,完成目标识别;根据全景图像的成像特性,设计了一种新的用于直线检测的快速hough变换算法,能够实时的提取出场地的白色标志线,并在此基础上设计了完全利用全向视觉信息的基于标志线的机器人自定位方法;最后设计了一种基于全向视觉信息和里程计信息的montecarlo定位方法,给出两种方法的定位结果,并分析实验结果,给出结论。 - The inversionless bm algorithm in rs decoder is implemented with serial mode , which avoids the inversion computation and only needs 3 finite - field multipliers . thus , the complexity of hardware implementation has been mostly reduced . a 3 - level pipe - line processing architecture is also used in the hardware and the coding circuit in rs coder is optimized by using the characteristics of the finite - field constant multiplier
Rs解码器的设计采用无逆bm算法,并利用串行方式来实现，不仅避免了求逆运算，而且只需用3个有限域乘法器就可以实现，大大的降低了硬件实现的复杂度，并且因为在硬件实现上，采用了3级流水线（ pipe - line ）的处理结构。
