Based on the solution you are looking for, this will determine the type of camera that you need on your drone, as you would have seen in the material, there are many alternatives, RGB/Infrared/ multispectral/hyperspectral cameras and even thermal, LIDAR and radar sensors.

Most cameras on brand manufacturer drones have a camera capable of producing both high definition still and video images. They generally have large capacity SD cards (removable memory devices) and can store large numbers of high-resolution photos and video files such as. raw or 4k

To carry the larger professional camera systems for Film and TV or specialist thermal or lidar systems, larger heavy-lift drones would be required. These not only have better lifting capacity but are more stable in windy conditions. The other thing to consider is the type of gimbal that holds the camera. On some drones, the camera position is fixed while others have gimbals that are 2 axis and others 3. If you wish to face the camera down to take the overlapping images required for many of the examples in this course, you’ll need a 2-axis gimbal. With cameras that take advantage of VR (Virtual Reality) devices then a 3-axis camera is required. Some drone models don’t come with a camera at all and third-party devices such as GoPro's are used.

On many drones, the camera can be configured for a variety and settings including burst and interval capture for time-lapse photography.

Cameras also come with various 'modes' besides the standard single shot. Click on the link below if you would like to find out more about these:

Taking it to the next level.

Virtual Reality headsets are becoming increasingly popular with drone developers and users. Several manufacturers have models available and are adding a new tool to the farmers' toolbox. These devices allow a second person to experience the flight while viewing a live feed in 3D through the VR headset. They offer an excellent training tool or opportunity for an expert to do the field analysis while a pilot flies the aircraft.

In Australia these devices are not to be worn by the pilot while they fly the aircraft However, the person wearing the headset can take control of the camera and take the photos/videos.
