Document Scanning is nothing new for mobile apps. I remember the first time that I installed a document scanning app was in 2010. However, Apple, Microsoft, and Google the giant tech companies got started to recognize the importance of document scanning technology recently. It is good to see the function appears in iOS Notes, Office Lens and Google Drive. Why is the document scanning being hot now? I think the reason is the quality of images captured by mobile cameras is getting better and better. More and more users tend to scan documents with cameras instead of traditional scanners. If you are not familiar with Android and iOS development, you can use HTML5. In this post, I will share how to create a simple web document management app using OpenCV.js.
Many excellent document mobile apps support not only image capture, but also edge detection and perspective transformation. If you are interested in these computer vision technologies, you can use OpenCV to create a free document scanner app yourself. In this post, I want to share how to use OpenCV-Python to create a web document scanner step by step.
If you are a C# developer, what technology you can use to create a cross-platform web document scanning app? The answer is ASP.NET Core and Dynamic Web TWAIN. In this post, I will share how to use these technologies to build a simple web app from scratch.
Dynamic Web TWAIN for Raspberry Pi is on Dynamsoft Labs now. No matter whether you are a Dynamic Web TWAIN user or not, if you want to build a document scanning and management system with low cost, you should experience this edition. Build a smart and wireless scanner with a $35 Raspberry Pi, and scan documents from any HTML5 supported web browsers on any devices including PC, laptop, smartphone and tablet. In this article, I will illustrate how to set up the environment and build a simple web app for scanning documents with no plugin.
