Department of Civil and Environmental Engineering, Carleton University CIVE 2004 - Bonus assignment 1 Page 1/3 CIVE 2004 GIS, Surveying, and Graphics 2016 Fall Term Bonus Assignment 1: making a 3D model of an existing building Due Oct. 28 th before midnight Assignment Objectives: The purpose of this assignment is to learn a new application for surveying existing buildings. Stu- dents will apply experimental software application developed by Autodesk. In computer graphics and computer vision, image-based modelling and rendering (IBMR) methods rely on a set of two- dimensional images of a scene to generate a three-dimensional model and then render some novel views of this scene. The traditional approach of computer graphics has been to create a geometric model in 3D using modelling tools and tries to reproject it onto a two-dimensional image. Computer vision, conversely, is mostly focused on detecting, grouping, and extracting features (edges, faces, etc.) present in a given picture and then trying to interpret them as three-dimensional clues. Image-based modelling and rendering allows the use of multiple two-dimensional images in order to generate directly two-dimensional images, skipping the manual modelling stage. This is on the basis of photogrammetric concepts and new developments. The increasing speed and power of computer systems, however, lead researchers in the computer vision field are developing calcula- tion intensive methods that could deal with uncalibrated imagery (i.e. no information about the dif-

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
