Key differences
Here are the main factors to consider when choosing a mobile document scanning solution.
Integration complexity
Building a document scanner with OpenCV requires extensive computer vision expertise. Developers must manually configure the entire scanning pipeline and build the user interface from scratch.
Scanbot SDK is an out-of-the-box solution with pre-built screens and Ready-To-Use-UI Components that make it easy and quick to set up.
Platform consistency
OpenCV is natively optimized for desktop applications, primarily using Python or C++. While wrappers exist for cross-platform frameworks, behavior may be inconsistent across systems. Additionally, OpenCV requires significant performance tuning for mobile development.
Scanbot SDK provides dedicated SDKs for mobile, web, and server-based applications, ensuring consistent behavior and performance across all platforms.
Support and developer resources
While OpenCV offers documentation for core functions, official guides for building end-to-end applications are notoriously scarce. Support relies entirely on the open-source community.
Scanbot SDK provides comprehensive documentation, platform-specific sample apps, and step-by-step integration guides. Furthermore, a technical support team with years of experience is available to assist you.
We were getting a lot of poor-quality document photos that our backend couldn’t process, and our attorneys couldn’t read. The Scanbot SDK solved this completely. In the five months since implementation, we’ve processed over 116,000 documents without a single complaint.
