Setup Note that we will be using a new conda environment for this project! If you run into import module errors, try pip install -e . again, and if that still doesn’t work, you may have to create a fresh environment. 1. Install Miniconda. It doesn’t matter whether you use Python 2 or 3 because we will create our own environment that uses 3 anyways. 2. Open the terminal (a) On Windows: open the installed Conda prompt to run the command. (b) On MacOS: open a terminal window to run the command (c) On Linux: open a terminal window to run the command 3. Navigate to the folder where you have the project 1 4. Create the conda environment for this project (a) On Windows: conda env create -f proj2_env_win.yml (b) On MacOS: conda env create -f proj2_env_mac.yml (c) On Linux: conda env create -f proj2_env_linux.yml 5. Activate the newly created environment (a) On Windows: use the command conda activate proj2 (b) On MacOS: use the command source activate proj2 (c) On Linux: use the command source activate proj2 6. Install the project files as a module in this conda environment using pip install -e . (Do not forget the .). Run the notebook using jupyter notebook ./proj2_code/proj2.ipynb. At this point, you should see the jupyter notebook in your web browser. Follow all the instructions in the notebook for both the code + report portions of this project. Submission Instructions Recheck you pass all local unit tests by entering the proj2_unit_tests directory and running the command pytest ./. This command will run all the unit tests once more, and you need to add a screenshot to the report. Ensure that the conda environment proj2 is being used. • Submit the code as zip on Gradescope at PS2 – Code. • Submit the report as PDF on Gradescope at PS2 – Report. There is no submission to be done on Canvas. Rubric Code: The score for each part is provided below. Please refer to the submission results on Gradescope for a detailed breakdown. Part 1: Projection Matrix on provided images 28 Part 3: Fundamental Matrix 20 Part 4: RANSAC 20 EC1: Fundamental Matrix decomposition 10 Total 68 (+10) Report: The report is worth 32 points. Please refer to the pptx template where we have detailed the points associated with each question. Deliverables The following code deliverables will be uploaded as a zip file on Gradescope. 1. proj2_code/fundamental_matrix.py (a) point_line_distance() 2 (b) signed_point_line_errors() 2. proj2_code/least_squares_fundamental_matrix.py (a) optimize() 3. proj2_code/projection_matrix.py (a) objective_func() (b) projection() (c) estimate_camera_matrix() (d) decompose_camera_matrix() (e) calculate_camera_center() 4. proj2_code/ransac.py (a) calculate_num_ransac_iterations() (b) find_inliers() (c) ransac_fundamental_matrix() 5. proj2_code/recover_rot_translation.py (a) recover_E_from_F() (b) recover_rot_translation_from_E() 6. proj2_code/proj2.ipynb 7. proj2_code/get_points.py 8. proj2_code/two_view_data.py 9. proj2_code/utils.py Do not create this zip manually. You are supposed to use the command python zip_submission.py –gt_username for this. The second thing to upload is the PDF export of the report on gradescope.
