PHOTOGRAMMETRY vs. LIDAR

Choosing the right sensors for your job

GABRIEL TORRES

In drone survey missions, the choice between photogrammetry and LIDAR depends heavily on the exact application. You also need to consider operational factors, such as cost and complexity. Knowing what outputs you really need will help you make the right decision. What is LIDAR and how does its output compare with results obtained with high-resolution RGB cameras and photogrammetry? In this article, we’ll explore the ways photogrammetry and LIDAR are actually quite different from each other, even if their three-dimensional (3D) outputs look similar. We’ll then dig deeper into specific applications and how photogrammetry can provide exceptional results for most missions at a fraction of the cost and complexity of LIDAR. Photogrammetry and professional, high-resolution cameras can cost-effectively generate 2D and 3D surveys, with absolute accuracies down to 1 cm…
