Build a Document Scanner

Explore how to build a document scanner project using OpenCV and C++. Learn to detect document edges, extract contours, order points correctly, and warp images to crop and isolate documents. This lesson teaches you to integrate multiple OpenCV functions into a cohesive scanning tool.

In this lesson, we’ll use most of the OpenCV functions and techniques to create a document scanner. For that, we’ll need an image that contains a document. The document scanner will find the edges of the document and crop the document, giving an output image containing the document only. The output ...
