Asset Inspection Quick User Guide
This document describes the simple workflow of capturing accurate asset data using the Drone Harmony Asset Scanner.
Asset Scanner is a part of the Android mobile application combined with the Drone Harmony Web App. Some steps of the planning workflow can be done in both apps. In such cases, the workflow in both apps is presented below.
The app is designed to allow a good combination of flexibility and simplicity. Drone Harmony supports customers and partners with training. If you are interested, please reach out to sales@droneharmony.com
Installation and License
Asset Scanner requires a Drone Harmony Enterprise license to use. If you still do not have one, please get in touch with sales@droneharmony.com.
To install the app, download the installation file (*.apk) from this link: https://droneharmony.com/apks/dh-djisc-2.7.1.apk and install it on your mobile device (or DJI RC Pro, e.g., Smart Controller).
The web app is accessible in your browser through the usual link: app.droneharmony.com
Step 1: Data import
You should use the web app to import data with accurate locations of your assets in CSV format before the flight planning and execution stage.
To create and edit a CSV file with locations of assets you can use a sample that we provide in the import menu or just use the text editor. In case you use a text editor, every value should be separated with commas, and the header row must include Site, ID, Latitude, and Longitude.
When importing a big site with numerous assets the software will separate it in the map view according to the numbering that you will provide the smaller plots (groups of assets) as shown in screenshot 1, in the site column.
Drag CSV file for processing.
Step 2: Site load in mobile app
Once you import data in the web app you should proceed to the mobile app with the same account that you have used for login in the web app. Turning on the cloud sync on the setup of the app or later in settings is essential to automatically load your imported data as a site from the web app.
Here are some screenshots that will point you on how to load the site on mobile, to begin with the flight execution stage:
Step 3: Flight planning
Once you successfully loaded the site in the mobile app you should hit the plus sign to choose between Automatic or Manual flight plan creation to proceed with the inspection. As of now, there are only two options, but we are going to add a variety of flight plans shortly, including customizable ones.
Step 4: Calibration
Calibration will allow you to correct the position of the asset and align it with the position of a tower on the map.
To calibrate the position you should visually put the top of the asset in the center of the red cross with a camera gimbal -90 degrees. The asset`s crossbar should be in the center and aligned to the red horizontal scale visible in the FPV view. Finish the calibration once the asset is well centered in the red cross, and proceed to the flight execution stage.
Step 5: Flight execution
The software will number the assets dynamically based on progress for your convenience and also mark with a green check those already inspected as shown in the screenshot.
When an inspection of a single asset is done you should press the `finish asset` button to proceed with the inspection of the next one if you have chosen a manual flight plan.
In case you have used the automatic flight plan you can take additional photos in manual flight mode before pressing the `finish asset` button.
Once you have finished with the single asset completely, the red point on a mini-map in the FPV view will show you the flight direction to reach the next nearest asset so you should not switch to the map view as it is time-consuming.
Step 6: Generation of the report
At the end of the inspection process, you will be able to generate a full daily report on the work done with the information on each scanned asset (inspection status, note from pilot), drone, pilot, and time the inspection was made. To achieve this you should just go to site storage to sync the daily scanned data to the cloud.
All uploaded images would be stored in folders according to the asset name and date as shown in the screenshot below.

Flight Planning (5-15 minutes)
Mission planning contains two short steps: Tower Setup and Flight Planning.
Step 1: Tower Setup (mobile app workflow shown)
The following steps are required to set up a tower model. The 3D view helps you visualize the tower model you are creating.
Choose the tower tool from the left-side menu
Place the tower center on the map
Provide a name, the height, and the radius of the tower
Create antenna racks (zero or more), this would be important for some of the plans
Confirm by clicking on “Create Tower”
Important: If you created the tower in the web app, you should save it as a Site before proceeding to flight execution.
Tips:
You can add more than one antenna rack.
You do not need to position the tower center very accurately during the planning stage. This position will be calibrated during flight execution.
If you are creating the tower in the web app, you can use exact GPS coordinates as an input form for the tower center.
Step 2: Flight planning
To ensure effective flight planning for optimal data acquisition, it’s crucial to tailor your approach based on the tower type and purpose of the inspection. Here are some general recommendations that should yield high-quality results:
1.Overview Mission: Begin with a simple orbit around the tower from an overhead perspective. The emphasis here is on capturing the entire tower, prioritizing the scene’s overall context over intricate details.
2. Comprehensive Tower Mission: Execute a stack orbit mission covering the entire tower, incorporating a subtle gimbal angle. This mission is designed to capture the complete tower structure.
Vertical offset between waypoints: 2-4 meters
Distance to the tower: 5-10 meters
Gimbal angle: -15 to 15 degrees
3. Antenna Detail Mission: Implement another stack orbit mission focused specifically on the antennas, utilizing a distinct gimbal angle to capture detailed information.
Vertical offset: 2-4 meters
Distance to the tower: 5-10 meters
Gimbal angle: -20 to -40 degrees
For the second and third missions, explore the option of setting a positive gimbal angle for one and a negative angle for the other, provided your camera allows it. This approach enhances the ability to capture nuanced details both above and below the antennas, addressing potential obstructions.
By adhering to these mission plans, you’ll navigate your flight effectively, ensuring a well-rounded and detailed 3D model tailored to the specific needs of your inspection.
Mobile/Web Planning
The following steps will allow you to plan a flight mission.
Tap on the “+” sign both in map view and 3D view to enter the plan catalog in the mobile app. In the web app, it is the blue “+” in the bottom right corner. Choose the desired flight pattern.
Choose take-off and landing location.
Adjust mission parameters if needed. Previously parameters will be cached. Mobile: Tap the orange button to finish. Web: Click on “Save” to finish
The mission is ready
Flight Execution (10-30 minutes per plan)
The flight execution requires the drone to be connected. You will see the drone telemetry and the FPV view appear on the screen.
Calibration
The calibration is a short manual mission that is designed to ensure that the flight execution is accurate and safe.
The calibration process would start automatically after each new battery change (unless hot-swapping is used for drones that have 2 batteries), it is a short manual 2-step mission that includes horizontal and vertical calibration.
Vertical Calibration (calibration of the tower`s height)
Fly the drone manually to the height of the tower top
Direct the camera gimbal forward (pitch 0 degrees)
Approve the calibration when the drone is at the same height as the tower top
Horizontal Calibration (calibration of the lat/long position of the tower)
Fly the drone above the tower and direct the gimbal down (-90 degrees)
Approve the calibration once the tower is well-centered in the Red Cross
You can always reset the results of the previous calibration or initiate the same calibration process as before the mission launch, here are the steps to access it:
Choose Menu -> Drone -> Calibration
Once the tower center is calibrated, a green circle will appear on the telemetry panel at the top of the screen. You will also see the shift that was made with calibration when tapping on the green circle.
Mission Execution
After the tower position has been calibrated, tower missions can be executed.
Mobile App
Tap on the mission tab and choose the mission to execute.
Tap on Launch to prompt the launch dialogue
Choose launch parameters.
Important parameters:
Flight speed (recommended is around between 0.7 and 1.2 m/s, so camera shutter will have enough time)
RTH Altitude (set to be higher than the tower and obstacles around it)
Recording Type (Photo Non-stopping is recommended)
Focus Handling (Set by the pilot by tapping on the screen, or automatically by the app for the following plans: Stacked-Orbits, Verticals, Helix)
Dewarping (Depends on the post-processing which you are going to make after data collection)
Parameter choices will be cached for future flight executions.
