1. Absolute Altitude (WGS84): The height of the drone relative to mean sea level (MSL).
2. Relative Altitude : The height of the drone relative to the takeoff point or the ground reference level.
Relative Height of Subject to Takeoff Point: Refers to the vertical difference between the height of the photographed object and the drone’s takeoff point. Appropriately adjusting this parameter can optimize modeling effect. If the height of the subject is unknown, please keep the default distance.
Route Speed: Set the horizontal speed during the execution of the oblique photography route.
Route Speed (Oblique): Set the vertical speed during the execution of the oblique photography route.
Route Height: Set the flight height when executing the oblique photography route, after reaching the safe takeoff altitude, to continue with the task.
Main Route Angle: By adjusting the main route angle, it can match the environment and mission requirements, balancing efficiency and safety while ensuring data quality.
Safe Takeoff Altitude: Set the altitude the drone must reach before proceeding to the next point in the route.
Heading lock: Lock the heading of the nose, ensuring the uniformity and stability of surveying and mapping data by reducing variables (attitude, angle, light).

Note:

Completion Action: Set the behavior after completing the mapping route task.
1) Return to Home: Return to the home location from the last waypoint of the task.
2) Landing: Perform a landing at the last waypoint of the task.
3) Hover: Hover at the last waypoint of the task.

Advanced Settings: Set heading overlap, side lap, external margin, and photo mode.
1. Heading Overlap: The percentage of the overlap area between two adjacent images on the same flight path within the nadir photography area, relative to the length of a single image.
2. Sidelap Overlap: The percentage of the overlap area between two adjacent flight lines within the nadir photography area, relative to the width of a single image.
3. Heading Overlap (Oblique): The percentage of the overlap area between two adjacent images on the same flight path within the oblique photography area, relative to the length of a single image.
4. Sidelap Overlap (Oblique): The percentage of the overlap area between two adjacent flight lines within the nadir photography area, relative to the width of a single image.
Margin: In oblique photography route tasks, the external margin (also known as buffer zone or extension area) refers to the additional planned flight and data collection area outside the target measurement area. In fixed-wing or vertical takeoff fixed-wing flights, the drone’s turning path can be planned within the margin area.
Photo Mode:
1. Equal Distance Interval Photo Capture: Ensures data uniformity through ‘spatial benchmarking,’ suitable for high-precision and complex scenario mapping.
2. Equal Time Interval Photo Capture: Relies on a ‘time benchmark’ and is only suitable for simple scenarios with stable speed.

Note:

In actual operations, Almost all high-precision mapping adopt equal distance intercal photo capture mode to avoid the impact of speed fluctuations on data quality.

4.4.5 Corridor Route

Strip-shaped parallel flight lines for surveying elongated areas (e.g., roads, rivers). Area coverage is achieved by mosaicking multiple strips, requiring controlled spacing to maintain side overlap.

4.4.5.1 Route Planning

Click the route planning button and select ‘Creat Corridor’ to plan a corridor route.

4.4.5.2 Corridor Route Setting

In the corridor route tab, you can name the current task, and configure settings such as camera selection, resolution viewing, route altitude, speed, safe takeoff altitude, altitude mode, completion action, and advanced settings.

Route Name: After entering the desired name in the input box, save the route, and you can view the current route in the mission library.
Select Camera: Choose a different camera for corridor route tasks, including the wide-angle/thermal infrared lens of the ZT30 camera, the wide-angle/thermal infrared lens of the ZT6 camera, and the A8mini camera.
Single Flight Line Mode: Activating this mode configures the drone to execute only the central flight path. The aircraft will not perform any extended flight operations to the areas on either side of this central line.

Note:

When the Single-Line Mode is enabled, the system will compute a minimum flight altitude for the operation. This altitude is a constraint determined by the selected camera parameters in conjunction with the pre-set overlap rate requirements.

GSD: GSD (Ground Sample Distance) refers to the actual ground distance corresponding to a single pixel in the image. After selecting the camera, the GSD data will be displayed.
Terrain-Following: After enabling the terrain-following switch, the drone will use downloaded terrain data to automatically adjust its flight altitude according to the preset terrain-following height.

Note:

The terrain-following altitude data is sourced from open-source databases and may deviate from actual terrain. Please ensure a safe flight environment.

Terrain-Following Flight Altitude: When the terrain-following function is enabled, this altitude value is set to determine the relative distance between the drone and the terrain during flight.
Same Expansion Distance: This function simultaneously sets the expansion width on both sides of the flight line’s centerline to ensure precise coverage of a strip-shaped survey area. When this option is disabled, the left and right expansion distances can be set individually.
Include the Center Line: When this option is enabled, the system will incorporate the pre-defined centerline into the generated flight plan.
This means the drone will not only fly over the expanded areas on both sides of the centerline but will also directly traverse the centerline itself.
Segment Distance: Once configured, this parameter automatically segments the entire flight strip into multiple sub-sections, each with the specified length. By setting an appropriate segment distance and uploading the target area, operational efficiency is maximized and battery power is utilized optimally while ensuring flight safety.
Heading lock: Lock the heading of the nose, ensuring the uniformity and stability of surveying and mapping data by reducing variables (attitude, angle, light).

Note:

3. Unlock the UAV following standard procedures. Manually pilot the aircraft to the predetermined altitude, then activate the capture function.
The preview window in the lower-right interface will subsequently update with the captured imagery. The UAV may now be landed to proceed with dedicated mission planning operations.
4. Operational Prerequisite: Distance measurement between the UAV and the subject must be acquired before proceeding with survey area delineation and parameter configuration.

Note:

If a SIYI series camera with laser rangefinder is installed, the system will automatically acquire the distance data. When using cameras without this functionality, the distance between the UAV and the subject must be manually confirmed and adjusted.

4.4.6.2 Bevel Route Setting

In the bevel route tab, you can configure settings including flight speeds, safe takeoff altitude, routee direction and completion action.

Distance from drone to subject: Refers to the straight-line distance between the UAV and the bevel subject during capture of imagery for route planning purposes.
Subject-to-object distance: Refers to the distance between the imaging plane of the camera and the actual subject being photographed.

Flight-to-subject distance: Refers to the vertical distance between the UAV’s flight path plane and the subject’s bevel surface during bevel missions.
Safe takeoff altitude: Set the altitude the drone must reach before proceeding to the next point in the route.
Horizontal / Ascent / Descent speed: Set the horizontal / ascent / descent speed during bevel missions.
Route direction:
1. Horizontal direction: Runs parallel to the bevel’s extension direction, making it suitable for large-area, elongated bevels with high operational efficiency.
2. Vertical direction: Perpendicular to the bevel’s extension direction, , making it suitable for narrow slopes and complex gradients, providing superior detail capture.
In practice, these two patterns are often combined to create a cross-hatch flight route, ensuring complete coverage and data accuracy.

Completion Action: Set the behavior after completing the bevel route task.
1. Return to Home: Return to the home location from the last waypoint of the task.
2. Landing: Perform a landing at the last waypoint of the task.

7.1 Common Errors

Steps to troubleshoot common issues such as data link connectivity problems and camera display issues.

7.1.1 Unable to Connect to Data Link

Solution for when the data link fails to connect (using UniRC7 as an example):
If the ground and air units are in normal communication, but you are unable to establish a successful data link connection with the ground station software, follow these steps for troubleshooting:

1. First, ensure that the air unit is properly connected to your flight controller using the correct data link cable.
2. If you are using a DIY data link cable to connect the air unit and your flight controller, please check:

Is the wiring sequence correct?
Are the TX and RX pins in the flight controller and air unit data link serial ports properly crossed?
Are Data Link 1 and Data Link 2 configured correctly?

3. In the “UniGCS” app, go to the “Link Information” menu and check the values to determine if the communication between the flight controller and the air unit is normal. When the communication is normal, the “Data Link Downlink” value will be greater than 0. If the value is 0, please go back to steps 1 and 2 to check the connection cables.

4. In the “UniGCS” app, go to the “Data Transmission Settings” menu and check the following:

Is the data transmission connection method set correctly?
If using PX4/ArduPilot open-source flight control or a custom flight controller, is the baud rate set correctly?
Check the data transmission connection settings in the flight control ground station software.

5. If using PX4/ArduPilot open-source flight control or a custom flight controller, try switching the data transmission cable to the TELEM 1 or TELEM 2 port.
6. Are both the ground station and sky end running the latest firmware?
7. If using a wireless hotspot for UDP data transmission, disable the Ethernet on the computer and try connecting again.

Note:

If you have followed the above steps and are still unable to identify the issue, please immediately contact your distributor or reach out to SIYI Technology for further troubleshooting and resolution.

7.1.2 Unable to Display Image

Troubleshooting for not displaying video images (using UniRC7 as an example)
If you are unable to view the video transmission via the SIYI link, please follow these steps to troubleshoot:

1. Check the connection:

Ensure that the ground end and sky end are properly synchronized (i.e., the status indicator light on either the ground end or sky end isgreen).
Verify that the camera is correctly connected to the sky end (check if the link and camera can be reached via Ping Tools).

2. Check software settings:

UniGCS Application: Verify that the camera address field is correctly set.

If you’re unable to view the video feed through the SIYI handheld ground station, please check the network status of your Android system:
Ethernet switch: Check if the Ethernet icon is displayed on the Android home screen. If not, go to the Android system settings and enable the Ethernet function.
