When it comes to aerial photography or photogrammetry, the best camera for the job is not always the most expensive one.

In fact, there are a few different factors you need to take into account when choosing a camera for UAV photography, such as lens type, sensor size, and megapixel count.

You also need to make sure that the camera is compatible with your UAV platform. So, what are the best cameras for UAV photogrammetry? Let’s explore!

What is Photogrammetry and What are Its Uses

Photogrammetry is the science of making measurements from photographs. It can be used to measure distance, angles, and areas. Drone pilots often use photogrammetry to create mapping products, such as orthomosaics (aerial photographs that have been corrected for perspective) and digital surface models (3D models of the ground).

Photogrammetry software can also be used to create 3D models of buildings and other objects. This type of software is typically used in conjunction with a drone-mounted camera. The camera takes a series of photos from different angles, which are then uploaded to the software. The software uses algorithms to stitch the images together and create a 3D model.

This model can then be used for various purposes, such as calculating volumes or measuring distances. In addition, photogrammetry can be used to create detailed inventory reports or assess damage after a natural disaster.

As a result, it is an essential tool for any drone pilot who wants to collect accurate data about their surroundings.
