3D Reconstruction from Multiple Images, Part 1: Principles by Theo Moons, Luc van Gool, Maarten Vergauwen

By Theo Moons, Luc van Gool, Maarten Vergauwen

3D Reconstruction from a number of photographs, half 1: rules discusses and explains the way to extract 3-dimensional (3D) types from undeniable photographs. particularly, the 3D info is got from pictures for which the digicam parameters are unknown. the rules underlying such uncalibrated structure-from-motion tools are defined. First, a quick evaluation of 3D acquisition applied sciences places such equipment in a much wider context and highlights their very important benefits. Then, the particular idea in the back of this line of study is given. The authors have attempted to maintain the textual content maximally self-contained, for that reason additionally fending off hoping on an in depth wisdom of the projective innovations that sometimes look in texts approximately self-calibration 3D tools. quite, mathematical reasons which are extra amenable to instinct are given. the reason of the idea comprises the stratification of reconstructions acquired from snapshot pairs in addition to metric reconstruction at the foundation of greater than photographs mixed with a few extra wisdom in regards to the cameras used. 3D Reconstruction from a number of photographs, half 1: ideas is the 1st of a three-part Foundations and traits educational in this subject written via an analogous authors. half II will specialise in simpler information regarding the best way to enforce such uncalibrated structure-from-motion pipelines, whereas half III will define an instance pipeline with additional implementation concerns particular to this actual case, and together with a consumer consultant.

Hence, the image m of the scene point M has coordinates (u, v, f ), where Y X and v = f . 1) Z Z Projections onto the image plane cannot be detected with infinite precision. An image rather consists of physical cells capturing photons, so-called picture elements, or pixels for short. 3 (left). Pixel positions are typically indicated with a row and column number measured with respect to the top left corner of the image. These numbers are called the pixel coordinates of an image point. We will denote them by (x, y), where the x-coordinate is measured horizontally and increasing to the right, and the y-coordinate is measured vertically and increasing downwards.

3 (right) ). 1), will have coordinates Y X + pu and v˜ = f + pv . Z Z These (˜ u, v˜)-coordinates of the image point m are still expressed in the metric units of the camera-centered reference frame. To convert them to pixel coordinates, one has to divide u ˜ and v˜ by the width and the height of a pixel, respectively. 2 Image Formation and Camera Model 321 the pixel width and height, then mu and mv indicate how many pixels fit into one horizontal resprespectively vertical metric unit. 2) Z Z where αx = mu f and αy = mv f is the focal length expressed in number of pixels for the x- and y-direction of the image and (px , py ) are the α mv pixel coordinates of the principal point.

As highlighted before, the difference with selfcalibration techniques as explained in this tutorial is that in the latter 328 Principles of Passive 3D Reconstruction Fig. 6 Calibration objects: 3D (left) and 2D (right). the same images used for 3D scene reconstruction are also used for camera calibration. , a set of 3D coordinates with corresponding 2D coordinates in the image for their projections. 6. These objects contain easily recognizable markers. Internal calibration sometimes starts by fitting a linearized calibration model to the 3D–2D correspondences, which is then improved with a subsequent non-linear optimization step.
