Aerial Imagery and Flying Orbits Techniques

Flying Orbits and Aerial Imagery

• To fly a low-level orbit, tilt the camera down to avoid capturing the sky, and aim for 20% of the image to be ground.
• Start by flying around the whole building, then elevate 15 ft and tilt the camera down again, not exceeding 15°.
• Repeat this process to maintain a minimum of three orbits, ensuring at least three images capture the corner of the building.

Importance of Overlap

• The goal is to maintain a minimum of three orbits to ensure sufficient overlap between images.
• Overlap is crucial for creating a 3D model, especially when dealing with complex structures.

Using DJI Go and Point of Interest Mode

• Set the point of interest over the top of the building using DJI Go and Point of Interest mode.
• Set the radius to ensure the whole building is captured, and then hit "go" to start the orbit.

Time Shot Feature and Image Capture

• Use the Time Shot feature under Photos to take a second-long photo, and then click the photo button once to continue capturing images during the orbit.
• The drone will take multiple images during the orbit, which will be used to create a 3D model.

Emergency Landing Spots and Safety

• Identify primary and secondary emergency landing spots to ensure safety in case of an unexpected event.
• Be aware of obstacles such as power lines, roads, and trees, and plan accordingly.

Mocha and Altitude

• Set the mocha (Minimum Obstacle Clearance Altitude) at 20 ft above the highest point in the area, which is 70 ft in this case.
• Establish a top orbit at 80 ft AGL to ensure good imagery and clearance from obstacles.

Image Capture and Avoidance

• Avoid capturing the sky and highways in the images, as they can cause issues with the 3D model.
• Use techniques to remove motion blur from the images if necessary.

Radio Etiquette and Communication

• Use radio etiquette to ensure clear communication during the mission.
• Request a brief call back from the VO to confirm receipt of commands.
• Use a standardized format for radio calls, such as "Team 3 to VO Drone 1, 40 ft AGL, counterclockwise."
