If you want to use Raspberry Pi as an economical way of detecting barcodes, you can take account for Dynamsoft Barcode Reader SDK. As a business software, Dynamsoft Barcode Reader SDK is designed for overcoming a variety of complicated scenarios with sophisticated algorithms and heavy computations. Although the SDK is flexible for customizing algorithm parameters, subject to the low-frequency CPU of Raspberry Pi, the tradeoff between recognition accuracy and detection speed is still a big challenge. In this article, I will use Socket client-server model as a substitute solution. Thanks to Sabjorn’s NumpySocket module.

Raspberry Pi Barcode Reader with DBR 5.2
Dynamsoft finally released Barcode Reader SDK v5.2 for Raspberry Pi. It is time to make an update. In this post, I will show you how to install the SDK, as well as how to write a simple Raspberry Pi barcode app using C/C++ and Python.
Raspberry Pi Live Streaming with USB Webcam
For the past week, I was looking for a live streaming solution to broadcast video from a USB webcam that connects to Raspberry Pi. This post will help you set up a live streaming server on Raspberry Pi step by step.
How to Resize Raspbian Image for QEMU on Windows
Raspbian is a free operating system based on Debian. It is the recommended operating system for Raspberry Pi. If you do not have a Raspberry Pi, you can experience Raspbian by running the OS image in the emulator – QEMU. In this article, I want to share how to resize the Raspbian image on Windows.
Scanner Sidecar Solution with Raspberry Pi
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.
Raspberry Pi Barcode Scanner in Python
Previously, I wrote an article Raspberry Pi Barcode Scanner with Webcam and Python illustrating how to build a simple barcode scanner using Dynamsoft Barcode Reader SDK and OpenCV from scratch. The method decodeFile() was used for detecting barcodes from an image file. To use the API, you have to write image buffer that obtained by OpenCV API to a file beforehand. Because the I/O operation takes too much time, this API is not suitable for real-time barcode detection from webcam video stream. Considering this scenario, I have added a new Python API decodeBuffer(). In this article, I will illustrate how to create and use the new API.
Resources for Learning Raspberry Pi
For the past few months, I have been learning Raspberry Pi. In this post, I will collect all relevant resources together in order to help readers build barcode applications on Raspberry Pi with Dynamsoft Barcode SDK.
How to Build Node.js Barcode Reader on Raspberry Pi
Node.js is available for all platforms including IoT devices like Raspberry Pi. In this post, I will demonstrate how to quickly create an online barcode reader on Raspberry Pi using Node.js and Dynamsoft Barcode Reader SDK.
Raspberry Pi Development with Visual C++ for Linux
During Build 2016, Microsoft released a Visual Studio C++ extension for Linux. With the extension, you can use Visual Studio to write C++ code for Linux devices. In this post, let’s take a glimpse of how to install the extension and how to remotely build and debug C/C++ code for Raspberry Pi.
How to Build C/C++ Barcode Reader App for Raspberry Pi
I have been playing Pi Emulator for a while. It is time to get my hands dirty on the real Pi device. In this post, I would share how to build my first C/C++ barcode reader application on Raspberry Pi.
