Prepare for the final thesis presentation

  1. 1. Reconstruction of 3D image for Indoor scene S1150046 Naoki Okazaki
  2. 2. Outline・Forecast・Motivation and Problem Statement・Related Work・Method・Result - case 1 : SIFT - case 2 : 2DCDP・Summary and Future Work・Backup Slides
  3. 3. Forecast SIFT 2DCDP VS. Improve !!
  4. 4. Motivation andProblem StatementThe present conditions: Wall Floor Difficult for Reconstruction andThe improvement of the problem : 3D reconstruction in indoor environment closer
  5. 5. Related WorkThe result of past study of 3D reconstruction in indoor environment : This system uses existing some packages and algorithmsStudy of the comparison of SIFT and 2DCDP performed in the past : This study shows utility of 2DCDP from a result of provided Matching points and Number of polygons.
  6. 6. MethodApply a common image data set to two packages : 1. Bundler Structure from Motion package (SIFT case) - Developed by Noah Snavely - SIFT algorithm can describe characteristics of feature points that are invariant to scale and rotation changes. One of data image 2. 2DCDP by my Lab - Developed by Yaguchi, Iseki, and Oka - 2DCDP preserves 2D pixel correlation and assures continuity and monotonicity in the input image. Search ・ Matching points ・ Calculation time
  7. 7. Result - Case of SIFTThe data obtained ・ Matching points : 75,000 points ・ Calculation time : 24 hours Details still under investigationThe reconstructed 3D image by obtained data Panel Bookshelf Three lines of desks PC rack
  8. 8. Result - Case of 2DCDPThe data obtained ・ Matching points : ・ Calculation time : //Im sorry. My experiment is not yet over.
  9. 9. Summary andFuture Work//Im sorry. My experiment is not yet over.
  10. 10. Back up//Im sorry. My experiment is not yet over.
