CHAPTER 8Imagery and Videos

Imagery and video are at the heart of drone data. They provide unprecedented views and quick visual analysis. Capturing smooth, professional quality video is equally valuable when it comes to analysis and gaining a higher perspective of a site. Similarly, detail rich graphic renderings are easily generated using annotation, photo editing, and 3D modeling software in combination with drone imagery and videos. This chapter explores the different ways imagery and videos can be captured and used to create infographics and renders (Figures 8.1 and 8.2).

Photo and Video Quality

At the time of this writing, most professional drones come equipped with cameras that can collect 4K images and video (3840 × 2160 to 4096 x 2160 pixels). Of course, a more customized drone setup can be configured with just about any standard DSLR camera. In the future, higher quality outputs are sure to be available (Figure 8.3).

4K images and videos offer a superior level of detail, great for the type of visual work described below. For most professional work, shooting the highest quality resolution is recommended because it will provide the best results and flexibility when working with images in editing software.

Using DJI Standard Apps

The DJI standard flying apps come loaded with camera and recording features. At its simplest, the app allows you to adjust the camera and capture photos, or to start a video recording, by clicking on the button in the app. It includes the ...
