First, I thank LeeAnn, my devoted wife of more than 20 yearsShe has been an unflagging fan, a counselor, and a demanding editor. She taught memuch of what I have managed to learn about how to express a thought in ink. Thanksto my mother who was sure I would grow into someone in whom she would be proudwhen facts should have dissuaded her Thanks also to my father for his insistence thatI obtain a college education; that privilege was denied to him, an intelligent man borninto a family of modest meansI am grateful for the education provided by Virginia Tech Go Hokies. The basicsof electrical engineering imparted to me over my years at school allowed me to graspthe concepts I apply regularly today. I am grateful to Mr. Emory Pace, a toughprofessor who led me through numerous calculus courses and, in doing so, gaveme the confidence on which I would rely throughout my college career and beyondI am especially grateful to Dr Charles Nunnally; having arrived at university froma successful career in industry, he provided my earliest exposure to the practicalapplication of the material I strove to learn. I also thank Dr robert lorenz of theUniversity of Wisconsin at Madison, who introduced me to observers some years agoHis instruction has been enlightening and practical. Several of his university coursesare available in video format and are recommended for those who would like toextend their knowledge of controls. In particular, readers should consider ME 746which presents observers and numerous other subjectsI thank those who reviewed the manuscript for this book. Special thanks goes toDan Carlson for his contributions to almost every chapter contained herein Thanksalso to Eric Berg for his numerous insights. Thanks to the people of KollmorgenCorporation(now, Danaher Corporation), my long-time employer, for their continuing support in writing this book. Finally, thanks to Academic Press, especially to JoelClaypool, my editor, for the opportunity to write this edition and for editing, printing, distributing, and performing the myriad other tasks required to publish a bookX1

360环视摄像头鱼眼四摄像头拼接算法
用于鱼眼摄像头的一个环视参考文档很不错,自己最开始做这个相关的项目就是参考这个文档,发现写的很是不错,非常值得参考特别有用的,哈哈哈哈哈哈哈哈哈哈赵三峰,谢明,陈玉明:基于逆向投影的全景泊车系统设计与实现其中,(x,y)表示校正图像的坐标,(x,y)表示鱼眼图像的坐标此算法的效果如图所示。1------图校正前后图像俯视变换clay.OB图离散化后的路面本文采用直接线性变换()来找到俯视变换的投影矩阵,这种方法的优点在于不需要知道摄像头视RR角等参数,只需要在图像坐标系下标定对特征点就可R以计算出个未知的参数,从而得到单应性矩阵,并利R用单应性矩阼完成俯视变换。其中,M表示合成图像的宽度,单位:像素;No表示直接线性变换的公式如下合成图像的高度,单位:像素;R表示合成区域的宽Coxi i+Coli+Cu22i +Cu3)度,单位:;R1表示合成区域的长度,单位(iam,0)表示图像的坐标,单位:像素;x,y表示合成区C102+(ny2+C12x;+CrC20x:+C21y+C2231+1)域路面的坐标,单位:。下面判断路面上的点被哪个摄像头拍到,因此将路其中,(2v)表示图像坐标,(xy2)为物体空间坐标,面分成八个区域,如图所示Co,co1,…,C2为未知参数。但是本文的物体选择的是路面特征点,因此公式的z=0,简化后的二维公式为:(左前前)(右前)IX).
