OpenLvVision Header

OpenLvVision OpenCV

OpenLvVision OpenCV is a powerful LabVIEW wrapper for the OpenCV library. It brings advanced computer vision algorithms, linear algebra, and signal processing capabilities directly into LabVIEW, utilizing efficient Mat handling and polymorphic VIs.

📘 Documentation: For a complete reference of all functions and detailed usage, visit openlvvision.org/docs/opencv/
This library is currently in active development. Additional OpenCV modules will be included in future updates.

🔌 Dynamic MAT API

The Mat type is reconstructed as closely as possible using malleable and polymorphic VIs. If a function can be done in OpenCV C++, there is a high chance it will also work in the LabVIEW version.
