PIRR – Stitching with PTGUI

This lesson introduces the image stitching process for panoramic infrared reflectography (PIRR) using PTGui, a powerful panorama stitching software widely used to assemble overlapping images into a single seamless high-resolution mosaic.

After acquiring a sequence of overlapping infrared frames with your Valeria panoramic head and an InGaAs camera, the next essential step is to combine them into a coherent panoramic image. The video in this lesson walks you through the typical PTGui workflow: importing the acquired frames, aligning them based on shared features, and generating control points to ensure precise registration. Using PTGui’s tools and interactive panorama editor, you can refine the alignment and handle multi-row scans to produce a detailed, continuous reflectogram of the entire work.

PTGui supports a variety of projections and formats and is designed for robust performance even with large image sets. By following the steps shown in the video, you’ll learn how to leverage PTGui’s stitching capabilities to create high-quality panoramic infrared images from your PIRR captures, turning a sequence of close-up shots into a unified reflectographic representation ready for analysis and documentation.
