Final Presentation

Description

Presentations of the projects are given a few days after the Final Demo to an audience of fellow student reviewers, the lab instructors, and occasionally faculty or even students from outside the class who are following up a project of personal interest to them. The style is formal and professional, and students should dress accordingly.

Requirements and Grading

Each project team has 25 minutes for a Powerpoint presentation and questions. Every group member must present their own work contributing to the project and be ready to answer questions. Individual grades are given, and everyone in the audience participates in evaluating the presentation. Talks are judged on the basis of presentation technique and of technical organization and content.

Points of technique include dress, use of display materials and their design for readability, clarity of speech, absence of annoying mannerisms, proper eye contact with audience and smooth transitions between speakers. Content is judged on use of a proper introduction, orderly and connected development of ideas, absence of unnecessary details, proper pacing to stay within the allotted time, and an adequate summary at the close of the talk. Quantitative results are expected whenever applicable. Here is a general outline to follow:

  1. Introduction
  2. Objective
  3. Review of original design, requirements, and verifications
  4. Description of project build and functional tests
  5. Discussion of successes and challenges, as well as explanations of any failed verifications demonstrating and understanding of the engineering reason behind the failure
  6. Details of other tests including tests not explicitly required for verification procedures
  7. Recommendations for further work

Any significant relevant ethical issues should be briefly addressed, preferably in a single slide.

Presentations will be graded using the presentation grading rubric. Two sample Presentation documents - with notes at the top - are available at: Sample PRES 1, Sample PRES 2

Here are some recent presentations you can refer to: FA20_Team13, FA20_Team3

Submission and Deadlines

Slides for your final presentation must be uploaded to your project page on PACE prior to your presentation time. Deadlines for signing up may be found on the Calendar. Sign-up for the final presentation is done through PACE. Remember to sign up for a peer review of another group.

# 3D Scanner

# Problem

Our problem is how to design an algorithm that uses a mobile phone to take multiple angle photos and generate 3D models from multiple 2D images taken at various positions. At the same time, we will design a mechanical rotating device that allows the mobile phone to rotate 360 degrees and move up and down on the bracket.

# Solution Overview

Our solution for reconstructing a 3D topology of an object is to build a mechanical rotating device and develop an image processing algorithm. The mechanical rotating device contains a reliable holder that can steadily hold a phone of a regular size, and an electrical motor, which is fixed in the center of the whole system and can rotate the holder 360 degrees at a constant angular velocity.

# Solution Components

## Image processing algorithms

- This algorithm should be capable of performing feature detection which is essential for image processing. It should be able to accurately identify and extract relevant features of an object from multiple 2D images, including edges, corners, and key points.

- This algorithm should be designed to minimize the memory requirement and energy consumption, because mobile phones have limited memory and battery.

## Mechanical rotating system

Phone holder that can adjust its size and orientation to hold a phone steadily

Base of the holder with wheels that allows the holder to move smoothly on a surface

Electrical motor for rotating the holder at a constant angular velocity

Central platform to place the object

The remote-control device can be used to control the position of the central platform. Different types of motors and mechanisms can be used for up and down, such as the stepper motors, servo motors, DC motors, and AC motors.

# Criterion for Success

- Accuracy: The app should be able to produce a 3D model that is as accurate as possible to the real object, with minimal distortion, errors or noise.

- Speed: The app should be able to capture and process the 3D data quickly, without requiring too much time or processing power from the user's device.

- Output quality: The app should be able to produce high-quality 3D models that can be easily exported and used in other software applications or workflows.

- Compatibility: Any regular phone can be placed and fixed on the phone holder with a certain angle and does not come loose

- Flexibility: The holder with a phone must be able to rotate 360 degrees smoothly without violent tremble at a constant angular velocity
