How to Make a Clean Roof Orthophoto for Solar Installations

Most roof scans are for a 3D model or a quick inspection. Every so often an engineer or a solar designer asks for something more specific: a true orthophoto of the roof, a straight top-down image they can measure and pull into their CAD workflow.

Portrait Orientation in Photogrammetry: When It Actually Helps

Is there anything to gain by scanning in portrait instead of the usual landscape? Sometimes, a little. But orientation is one of the least important decisions you make on a scan, and it is worth understanding why before you give it any more thought than that.

A Short History of Photogrammetry: From Balloons to Drones

Photogrammetry feels like something the drone era invented. It did not. The idea of pulling measurements out of photographs is roughly 170 years old, which makes it older than the airplane and a lot older than the computer.

Photogrammetry Settings: A Practical Capture Checklist

This is a practical photogrammetry settings checklist built around that: the camera and drone settings I actually use, how to handle overlap and flight patterns, what to check before you start, and a cheat sheet at the end you can screenshot.

Top 10 Photogrammetry Misconceptions Part 2 – Advanced Myths

A while back I published a list of the most common photogrammetry misconceptions I kept running into. That post focused on the basics: gear, megapixels, settings, and other things beginners often get wrong.

What Actually Affects Photogrammetry Accuracy?

Photogrammetry accuracy is one of those topics that seems straightforward at first. You take photos, run them through software, and expect accurate results. In reality, it does not quite work like that.

Vertical Coordinate Systems in Photogrammetry – Ellipsoid vs Geoid Explained

Vertical coordinate systems usually go unnoticed until something stops matching. A model aligns perfectly in 2D view, but elevations are off. Volumes look reasonable, yet they do not match survey results.

Photogrammetry 202 - Pixpro Blog Index

In our final blog post of the year, we are indexing Pixpro photogrammetry blog posts from the last two years. After publishing regularly for a while, things tend to scatter: posts about workflows, Pixpro features, hardware tests, random experiments, use cases, comparisons.

Travel Photogrammetry - More Fun than 2D Photos

Sometimes a 2D photo does not do justice to a moment or a place, and you wish you had something more… dimensional. Something that captures shape, texture, and the little details that flat images tend to flatten even more.
