04. Bevel Route

Routes designed for object surfaces (e.g., side walls, slopes). The flight path maintains an adaptive distance from the bevel, ensuring clear imaging of bevel details. Commonly used for slope monitoring and facade surveying. Only vertical facade routes are supported in the current version.


1. Click the route planning button and select the "Create Bevel Route" option.

2. Once a blank small window pops up at the bottom left of the interface, you can start route planning.

3. Unlock the drone per the usual procedure, manually control the drone to take off to a preset altitude, then click the photo button. The small window at the bottom right will update with the captured image. Land the drone and focus on subsequent route planning.

4. Distance data from the drone to the subject must be obtained before further planning the survey area and completing parameter settings.

5. In the Bevel Route tab, you can set various speeds, safe takeoff altitude, route direction, completion action, etc., for the mission.

07. Route Information Estimation
Estimates route length, number of waypoints, flight time, number of photos, and survey area for the current route. Actual operations may deviate from estimates, it is recommended to add a 10%-20% redundancy buffer during actual operations to handle unforeseen circumstances.

image

08. Route Progress Display
During a mission, a dynamic progress bar appears below the title bar, indicating the completed route percentage. The bar length increases as the mission progresses.

image

09. Voice Broadcast

Provides real-time audio alerts for critical flight statuses (low battery, arming, disarming) and flight information, reducing user visual monitoring load and enhancing safety monitoring and coordination efficiency on-site.


10. Resume Mission From Waypoint
After a drone mission is interrupted, the drone can continue the remaining route from the waypoint before the interruption point, without starting over from the beginning. Applicable to all route types except bevel routes.

1. After a mission interruption, wait for the drone to return, land, and disarm. A prompt indicating an unfinished route mission will pop up on the main screen, click 'confirm'.

image

2. When the drone is ready again, please manually unlock the drone, lift it to a safe altitude, and click the "Start Mission" button. The system will pop up a "Continue Mission" dialog with options:

    • Cancel: Terminates the current auto mission. The drone stops executing the preset route.

    • Start Over: The drone restarts the full auto mission from the first waypoint.

    Continue Mission: The drone continues the remaining route from the waypoint before the previous interruption point, ensuring mission continuity.
