1、基本配置 Mobile device with Android 4.0 or later with at least 500 MB of free space to store the images. DJI Phantom 2 Vision+ (optimal, recommended) or DJI Phantom 2 Vision (compatible).Step 1. Prepare the droneWarning:Know your drone and how to fly it manually.Before using Pix4Dmapper Capture App, it
2、is required to first learn how to fly the drone manually. Manual control of the drone is the only way to avoid obstacles or get back a drone that flies away due to GPS interferences.For more information have a look at the drones user manual:DJI Phantom 2 Vision+ User ManualThe DJI Phantom 2 Vision+
3、is an autonomous and self-driven drone. The App is connected to the drone through Wi-Fi. Before takeoff, the App sends to the drone the GPS position of a predefined number of waypoints. During flight, the drone will follow these waypoints. The App sends a signal to the drone using the Wi-Fi each tim
4、e an image should be taken. Wi-Fi connection with the drone is required. If the Wi-Fi connection is broken, images are not taken anymore. However the drone continues the mission as the waypoints are saved on the drone before takeoff. Good GPS signal is required. If the drone misreads the GPS coordin
5、ates internally, it might fly away in a random direction. This happens when the drone is flying in an environment where the GPS signal gets interferences. For example it may happen if the drone flies close to large metallic structures or in areas where the GPS signal bounces back on objects such as
6、high buildings. Manual control is required to get back the drone. Obstacles: Ensure that no obstacle is between the drone home/takeoff point and the flight altitude during takeoff or landing. Battery: As the battery lifetime depends on multiple factors such as wind, altitude, temperature, etc., it i
7、s impossible to predict the lifetime of the battery. If the App is connected to the drone through the Wi-Fi and the battery is under 20%, the drone flies home. Manual control might be required at that stage.Important: Choose a clear takeoff/landing zone of at least 10x10 meters that can get easily G
8、PS signal. Before taking off, check that: The drone, remote controller and range extender batteries are charged. The propellers are correctly mounted. The propellers/engine are functioning. Do not fly over crowds. Respect your regional and national flight regulations.Step 2. Prepare the missionThere
9、 are 2types of missions: Grid Mission: Recommended for most of the environments. It ensures that the images are taken with the optimal overlap required to get accurate 3D models and maps. Free Flight Mission: Recommended to map more difficult objects (e.g. sides of houses, towers, pylons, bridges, e
10、tc). It requires to pilot the drone and to understand how to fly an optimal flight path.Prepare a Grid MissionThe grid mission is well suited for most of the environments. It ensures that the images are taken with the optimal overlap required to get accurate 3D models and maps. To prepare a grid mis
11、sion:1. Open the App.2. (optional) In the home screen, clickSettingsand change the overlap between the images as well as the angle of the camera.For more information about the settings:203873435.3. In the home screen, clickGrid Mission.TheMap Viewis loaded.Tip: If you are connected to the Internet,
12、a background map is displayed. The mission can also be prepared in your office. The displayed map is cached and will be available when starting the mission in an area without Internet connection.4. (Optional) On the left of the screen, select the desired flight altitude.5. Place the grid over the ar
13、ea of interest. To move the grid, press with the finger in the middle of the grid and drag it. To rotate the grid, press with the finger on one of the arrows on the border of the grid and rotate it. To resize the grid, press with the finger on one of the small squares on the grid border and drag it.
14、Note: Grid size: The default grid settings (50x50 meters) define a small flight of about 5-10 minutes that works in almost all conditions. By increasing the grid, the flight time is increased as well. Ensure that you have enough battery if you increase the grid size. The battery lifetime depends on
15、many factors such as wind, temperature, age of the battery, etc. Grid color: The grid is displayed in green as long as the size is optimal to perform a flight with a fully charged battery. If the grid size becomes slightly too large such that there might be not enough battery to perform the whole mi
16、ssion, the grid is displayed in yellow. If the grid is too small to ensure good quality 3D models and maps it is displayed in yellow as well. If the grid is too large to be flown with a fully charged battery, it is displayed in red. In this case it is recommended not to fly and to give the grid a better size.6.Start the missiononce it is prepared.Prepare
