Description
Bubble sheet multiple choice scanner and test grader using OpenCV and Python
The goal of this project is to build a bubble sheet scanner and test grader using Python and OpenCV.
To accomplish this, our implementation will need to satisfy the following 7 steps:
- Detect the exam in an image.
- Apply a perspective transform to extract the top-down, birds-eye-view of the exam.
- Extract the set of bubbles (i.e., the possible answer choices) from the perspective transformed exam.
- Sort the questions/bubbles into rows.
- Determine the marked (i.e., “bubbled in”) answer for each row.
- Lookup the correct answer in our answer key to determine if the user was correct in their choice.
- Repeat for all questions in the exam.
