Computer-Vision-Assisted Origami

Project Website Project Poster Project Video

This program utilizes the capibilities of the OpenCV library to help the user fold a piece of origami. There are three main ways that the user can choose to engage with the program. The first is for the instructions to be displayed in the upper left hand corner of the frame of the webcam's footage. The second is for the instructions to be projected onto the paper (as long as it is parellel to the table). The last (which is still a bit experimental) is for the instructions to be projected onto the paper regardless of its orientation to the camera. Each of these modes requires the user to push a key for the next step to be projected/displayed.

Dependencies:

To obtain the following dependencies, simply run pip install -r REQUIREMENTS.txt

• OpenCV 3
• Numpy 1.14.2
• PyQt5
• pygame
• pyttsx3

Quick start:

To run this software, execute main.py by typing ./main.py in the cv-assisted-origami directory, and you should be presented with the following GUI.

Usage:

Before running the program, it is necessary to set up an external webcam so that it faces downward at a table. This is where all the folding will take place.

Modes:

1. Unassisted: Minimum Viability

   To begin, execute the fold instructions as they are displayed on-screen. Confirm fold completion and repeat until the final instruction is reached.

2. Assisted

   To begin receiving valid webcam input, find a surface that contrasts highly with the paper being folded, and position the webcam above it. Starting from the first instruction, continue folding the paper as instructions appear on-screen.

3. Augmented: Stretch

   Follow the instructions described in (2), but fold across the line that is projected over the paper on-screen. Continue folding over new lines as they appear on the paper until lines are no longer visible.
