Multiple View Geometry (3) 썸네일형 리스트형 Conic Conic can be represented by 6 parameters, $$ax^2 + bxy + cy^2 + dx + ey + f = 0$$ it can also represented with matrix form like this: \begin{pmatrix} a &b/2 &d/2 \\ b/2 &c &e/2 \\ d/2 &e/2 &f \end{pmatrix} The relationship between point and conic is like this: $$x^TCx=0 \ \ \ where \ x = (x_1, x_2, 1)$$ Dual conic C*: composed of a bunch of lines which is a tangent line. $$C^* = kC^{-1}$$ ** Cha.. Projective Geometry and Transformations of 2D # Day 1-1 : Homogenous Coordinate Before you read! This book has two notations,"Geometric Representation" and "Algebraic Representation". It would be confused of these combined notations. These two notations which mean points are same. I just wanna let you know! $$X : (x, y) \in \Re^2 : algebraic$$ $$X : (kx, ky, k) \in P^2 : Geometric $$ The line can be written in same rule. when k is not zero... Hello MVG! I'm gonna write down the memo of study "Multiple View Geometry in computer vision". # Day 1 Having read the foreword of this book, this sentence is interesting. "No designers of systems using cameras hooked to computers that will be built in the foreseeable future can ignore this work" The contents of the introduction had a summary of this book from 1-1 to 1-10. When I finish reading this, I'll .. 이전 1 다음
