In the autonomous capturing mode, the Altizure App controls DJI drones with the help of DJI SDK to capture vertical and oblique photographs.

The capturing is designed for 3D oblique photogrammetry that reconstructs true 3D models, in addition to the traditional photogrammetry with only vertical views for generating 2D orthomosaics(orthomaps or orthophotos).

Selects an area to be mapped, then the app automatically generates and flies the five paths over the area. The first path corresponds to the vertical views, while the other fours corresponding to the oblique views with the camera oriented about 45 degrees downward looking in four different directions. You may check one example of such patterns of 5 paths by one of the users:
The five paths are necessary for true 3D models. But If you want to mainly produce a 2D orthographic image, or an orthomosaic, you may opt for taking only vertical views, which is the first path generated by the app. Then you can forego the remaining four paths of oblique views.

The supported UAVs

Mavic Pro Inspire 1/2 Phantom 3 (Pro / Advanced / 4K / Standard) Phantom 4 (4 / 4 Adv / 4 Pro V1) M100 M600 M600 Pro A2 / A3 + LB2 (Testing) Phantom 4 Pro V2.0 (Testing) Mavic Air The step by step guide Please make sure:

(a) you have the latest firmware installed on your aircraft.

(b) your phone is connected to the Internet when launching the Altizure app for the first time (first time only). DJI will check our API key and activate Altizure app on your device. This is required for all 3rd-party app using DJI SDK.

(c) a MicroSD card with at least 1GB free space is inserted in your drone.

(d) you have read through DJI's user manual, understood limitation of your aircraft. For example, you should know the range of height and radius your aircraft can fly safely.

(e) you are able to control you aircraft without any app. For example, you should be able to land your aircraft manually using joysticks, or start/stop Return-To-Home function on remote controller.

(f) you have at least 6 months experience in using DJI's aircraft, obtained all licenses for using DJI's aircraft, if required in your country or region.
Before launching the app:

(a) Turn on your drone and remote controller. Find the Flight Mode Switch on controller (labelled P-A-F) and make sure it is set to F-Mode. For Phantom 4, keep the mode switch in P-Mode.

(b) Adjust the exposure of the drone camera in DJI Go app. Incorrect exposure may result in over-exposed or blurry photos.

(c) Quit DJI Go app completely. Check the troubleshooting guide if you need help with this.

(d) Connect your phone and the remote controller using a USB cable. A window will pop up asking you to select which app you want to use, press Altizure, then "just once". If you use phantom 3 standard/4K, please connect via Wi-Fi in the same way as you use DJI Go.

(e) Click Capture button. The map will be displayed on the screen.

(e) Click Capture button. The map will be displayed on the screen.

Scroll to pick the proper altitude.

Place a rectangular region you want to cover, adjust its position (drag the green rectangle), size (drag the blue dot), and direction (touch rectangle and rotate with another finger).

Click the five direction buttons on the bottom of the screen to select flight path. The first path on the left is required while the other 4 paths are recommended. Please complete as many paths as possible to improve the quality of your 3D model.

Check the safety of your flight paths (indicated by the white line with two arrows) and make sure there is no obstacle along the path. Click confirm button to save this task. The task can be reloaded from our mission management view later.

Click to take off. The drone will start capturing and land at current position.


The upload speed is slow, sometimes it fails due to timeout error. If your drone does not response, press the take off button again to re-upload the flight task.

After completing a task, there will be a dialog with 3 options: "continue", "return", and "hover". If you select "return", the drone will fly back and land on the take off position. If you press "continue", it will start executing next task. If you select "hover", the drone will stay in current position and do nothing.

When the battery is low (< 30%), there will be a dialog that notify you to exit the mission and return home. If the battery is critically low (< 20%), your drone will exit the mission and return directly. You can cancel the returning by pressing the return-to-home button on remote controller.

After all tasks finished, find the photos in the MicroSD card and upload to altizure.com to generate the 3D model.

Frequently asked questions

Q:Does it require Internet connection in the field?

A: Not necessarily. You don't need it to fly the drone, but you need the Internet connection to load the map, at least initially.

If you anticipate low or zero Internet connectivity in the target area, you could start the app, load the map, set up your fly path and put the app in sleep mode before you set off to the field. In other words, you could complete step 1 to 5 at home. Your drone will not take off until you press the take off button in step 8.

Q:Does it automatically adjust the gimbal from straight down to 45 degrees? Operate the shutter automatically?

A: Yes! the whole is fully automated by the app.

It calculates the fly path based on your indicated data collection area, makes your drone fly the generated path by itself, and takes photographs during the path automatically. When the task completes or when the battery is low, the drone automatically lands to the take-off position.

All you need to do is: configure the data collection area, press the take off button and watch your drone complete its path.

Q:How high can I fly my UAV using Altizure app?

A: At most 500m. This constraint is set by DJI SDK and DJI's firmware. In the future, DJI may restrict the flight height according to the law of your local government. Our app may not be able to make your UAV take off if such constraints are not satisfied.

Q:Do I need to run the SDK Developer firmware on the aircraft now?

A: With the latest version of SDK, you do not need developer firmware anymore. Simply upgrade your firmware to the newest version in DJI Go app.

Q:I am not comfortable with auto flight, especially when I do not know how your app work.

A: With the help of DJI simulator, you could have a virtual trial of the app before using it in the field. You are recommended to do experiments in the DJI simulator, to get familiar with our app.

In addition, during the capturing process, you can stop the flight anytime and manually control your drone, by switching the Flight Mode to P-Mode (S-Mode in Phantom 4). Don't forget to switch back to F-Mode (P-Mode in Phantom 4) before next flight!

Troubleshooting

The app crash immediately after I click the Capture button.

You need to quit DJI Go process completely following this procedure:

Go to the Setting screen of your phone, and enter Apps section.
Go to Running tab by swiping from right to left, find and stop all process and services of DJI Go.

I cannot launch DJI Go app after using your app.

Please follow the same procedure as above to quit all processes related to Altizure.

After I click the take-off button, the drone does not start the auto flight.

After pressing the take off button, the app will start to upload flight path coordinates to the drone. If the upload progress stopped for a long time, please press the take off button again to re-upload the flight task.

Why are my photos so bright / dark/ blurry?

So far, Altizure app does not control the exposure of your camera. The app only handles the flight and gimbal. To set the exposure properly, you need to use DJI Go to check and set the exposure of cameras (e.g. make sure the photos are neither too bright nor too dark, and set a short exposure time to avoid capturing blurry images).

The simplest strategy is to capture at a time with enough illumination. It is not a good practice to capture at dawn or dusk.

Disclaimers

This application is a photo collection assistant, which cannot replace DJI official app. If you have multiple remote controllers, please use our application on the Slave controller along with DJI official app on the Master controller, and pay attention to your drone and its flight. Put the mode bar to other mode and back in order to take back the manual control when necessary.

Altizure does not take any responsibility of any damage caused by or loss of your drone.
