# 3DR EAI (Exposure-Aperture-ISO)3DR EAI runs on the Canon Hacker Development Kit (CHDK), a powerful opensource tool that expands the functionality of Canon point-and-shoot cameras. 3DR EAI optimizes image exposure and integrates with the Pixhawk autopilot to enable distance-based imaging. This software is designed to load off the camera’s SD card, leaving the original Canon programming intact. The yellow switch on the side of the SD card allows you to lock or unlock the card. Lock the SD card to run 3DR EAI; unlock the SD card to save images to your ground station or to boot the camera with its original programming. For more information about 3DR EAI, see page 43.

Pixhawk autopilot system Pix4Dmapper LT 3DR Edition Canon SX260

3DR EAI

To create a map, the Aero flies an autonomous mission over the survey site, using the integration between the Pixhawk autopilot and custom-programmed camera to capture images at a consistent distance interval. Pix4Dmapper then stitches these images together into a georeferenced, orthorectified mosaic. The accuracy of the map depends on the configuration of the mission. Planning a mission that captures high-quality images requires balancing the Aero’s operating parameters with the environmental factors at the survey site.

# Mission Planning Operating Parameters

Mapping system diagram1 Open Mission Planner, select Flight Plan , and zoom to your flying location. 2 Right-click on the map, select Map Tool and Prefetch , and accept the defaults prompts. Mission Planner will download the maps for the selected location to your computer.

3 Mission Planner will attempt to load the map data from the current level of zoom down to the closest level of zoom available. However, it can take hours to pre-fetch every level of zoom, and it is unlikely that the closer levels will be useful in planning the mission. To shortcut this process, check the slider on the right side of the map. The levels of zoom are represented by this slider from 0 (bottom) to 25 (top). Press the ESC key to skip levels of zoom at a greater detail than you need for mission planning.

# Load Maps Mission Planner allows you to plan the mission away from the mapping location; however, it is important to assess the environmental conditions on site at the time of the mission and adjust the flight plan if necessary. Alternatively, you can plan the entire mission at the mapping location. To create or alter the mission, Mission Planner requires an Internet connection to access the maps. If you’re unable to access the Internet on site, follow the instructions below to pre-fetch the maps within Mission Planner while you have Internet access.2 Right click on the map.

Set OverShoot The Aero has a minimum turning radius of 90 degrees. To accommodate the sharp angles of the survey mission, set both OverShoot parameters to 50 to have the Aero overshoot the waypoints on either side of the polygon by 50% to ensure that the complete area of the polygon is covered by the images.
OverShoot will affect flight time. Ensure that the total estimated flight time is less than the Aero’s maximum flight time of 40 minutes.

Adjust Overlap and Sidelap Overlap and sidelap are set to 50% and 60%, respectively, by default. See page 42 for an in-depth discussion of these parameters. Adjust StartFrom During the mission, you will maintain contact with the aircraft through the RC controller and ground station signals. If your mission is likely to experience a loss of signal, it is best practice to start from the corner of the mission farthest from the launch point. In this example, TopLeft is the corner of the mission farthest from the launch point.

# Configuring Automatic Takeoff and Landing
If you selected automatic landing in the Survey Tool by checking the Add Takeoff and Land WP’s option and unchecking the Use RTL option, you will need to configure the landing waypoint pattern manually at this step in the mission planning process. To begin, determine the direction of the wind and select an unobstructed area 200-500 m in length leading to the launch point, into the wind. On the main Flight Plan screen, create a series of waypoints along this path to decrease altitude gradually from the survey altitude to 0, ensuring that:

» Turns along the flight path are greater than 90 degrees. » The altitude decreases by a maximum of 20 m between waypoints » There is at least 20 m between each waypoint » The Grad % does not exceed 20% To add a waypoint, right click on the map in the location of the waypoint you would like to add, and select Insert WP . For each waypoint you add to the mission, Mission Planner will prompt you for the new waypoint’s place in the script: Add the series of landing waypoints immediately before the LAND waypoint in the script of events. For the first waypoint in the pattern, add it to the mission immediately following the DO_SET_CAM_TRIGG_DIST waypoint at the end of the mission. Specify the altitude of each waypoint and check the distance and gradient angle in the waypoints table.

Always fly in accordance with your location regulations and these best operating practices.

Always fly at least 100 feet (30 m) away from people, vehicles, and buildings. Make the safety of people and property your first priority! Always fly below 400 ft (120 m) and within your visual line of sight. Don’t let the Aero get too far away from you; make sure you can always see its orientation. Don’t fly in low light, rain, or other conditions that might impede visibility.

Always fly at least 5 miles (8 km) away from airports and other areas where pilots operate manned aircraft. visual line of sight 400 ft (120 m) Before you fly, determine the boundaries of your safe flying area. If the Aero moves outside the designated area or exhibits instability in flight, switch to fly-by-wire mode and land the plane manually. Always be ready to regain manual control of the plane in the event of an unsafe situation. The Aero will not avoid obstacles on its own, including during missions. As the operator, it’s your job to recognize and avoid obstructions while flying. When planning missions, ensure that the selected altitude is appropriate for all geographical features of the area, including terrain.
