E-con Systems provides a C++ SDK for Windows and Linux and includes some standard analysis examples using OpenCV such as height estimation, face detection, and point cloud generation. However, to be able to achieve higher stitching stability and quality of the final images at least being familiar with the theory is recommended (see Stitching Pipeline). py before the main python script. The other way is to add OpenCV classes for working with the camera to your project directly. jsonin the project folder.
