X10 System Installation and Disassembly

Warning:

• When installing X10 system, please handle with care to protect equipment;
• During the installation and disassembly of the equipment, please ensure the UAV is switched off to avoid damage to the equipment due to live operation;
• After disassembling the equipment, please put all the parts of the equipment back to the carrying case according to their positions and check whether the parts are complete.

Aerial metric camera installation and disassembly
The aerial metric camera is connected to the LiDAR main body by two hand screws. Step1, align the metal contacts at the bottom of the camera with the connector and place it in the mounting slot; Step2, tighten the hand screws on both ends of the connector by hand and further tighten the screws by a Phillips screwdriver.

Disassembly of the aerial metric camera from the LiDAR main body. Use a Phillips screwdriver to remove the two hand screws on each end of the connector to remove the aerial metric camera.

SKYPORT adaptor installation and disassembly
Installation between the SKYPORT adaptor and the main body. Step1, insert the SKYPORT adaptor to the main body in the direction of the down arrow in the figure, in which a socket is set to avoid reverse insertion; Step2, rotate the fix ring clockwise in the direction of the rotating arrow as shown in the figure to fix and install the SKYPORT and the main body.

Disassembly of the SKYPORT adaptor from the main body. Step1, rotate the fix ring counterclockwise in the direction of the rotating arrow as shown in the figure to separate the SKYPORT from the main body; Step2, pull the SKYPORT adaptor upwards to remove the SKYPORT adaptor.

High-capacity USB-disk installation
As shown in the figure below, align the USB disk with the USB socket and insert the USB-disk into the socket.

Main body installation and disassembly
The white circular mark on the main body corresponds to the red circular mark on the UAV rack. After stuck, rotate the main body counterclockwise in the direction of the rotating arrow shown in the figure. The red circular mark on the SKYPORT adaptor corresponds to the red circular mark on the UAV rack, if a “click” is heard and the equipment can’t be twisted, it means the installation is successful.

The red circular mark on the main body corresponds to the circular mark on the UAV rack. Press the button indicated by the arrow shown in the figure, and rotate the equipment clockwise as in the direction of the rotating arrow in the figure, when the white circular mark on the SKYPORT adaptor aligned to the circular mark on the UAV rack, the equipment can be removed to finish the disassembly.

Antenna component installation and disassembly

Data Collection

Client Installation

Method 1:
insert the TF card into the M300 remote control, read the control software installation package “EasyPilotAccess” in the TF card and click to install.

Method 2:
download the W series product control software installation package from the download interface on the official website, connect M300 remote control to PC via data cable, copy the downloaded installation package “EasyPilotAccess” to remote control storage. Find the installation package on the remote control operation interface, click to install.

In the pop-up permission dialog box, authorize the required permission for the software, if not, the software may not be installed successfully. Click Continue to install and wait for the software installation to complete.

Flight Planning

Click icon to open the control software. Two modes of “Create Flight” and “Import KML” can be chosen.

Create flight mode

Under Create Flight mode, there are three task modes can be selected, “Waypoint Flight”, “Mapping by aerial photography” and “Strip Flight”.

“Waypoint Flight”

The waypoint flight mode operation is as follows:
Manually click the map to add waypoint, the UAV will fly according to the connection sequence of the waypoints. Click a waypoint to select it, and long press the waypoint to drag its position. After setting the flight, open the menu bar on the right side, the arrow key at the bottom can also be used to fine-tune the waypoint position. Select the corresponding LiDAR model on the menu bar interface (If the equipment is connected, APP will automatically identify the equipment model). Set flight height, flight speed, emit frequency, scanning angle, actions after completing the flight according to the requirements.

In the detailed menu interface, ground reflectivity and single waypoint parameters can also be set. After the ground reflectivity is set, the flight height will be limited. If the set flight height exceeds the maximum flight height of the current ground reflectivity, the number of flight height options will turn yellow.

• Click on the left side to save the flight.

“Mapping by aerial photography”
The Mapping of aerial photography operation is as follows:

Select a task area manually on the map, long press the corner point to drag the point and modify the location of the area boundary. Click the “+” symbol between the two corner points to add a new corner point between the two corners to adjust the task area. After setting the task area, open the menu bar on the right side, select your LiDAR model (If the equipment is connected, APP will automatically identify the equipment model). Set flight speed and flight height. The required point cloud and image overlap can be set in advanced settings.

After setting the overlap, adjust the flight height, APP will automatically calculate the flight interval to generate flight according to the set overlap. Entry point “A,B,C,D” can be selected according to the takeoff position.

If Terrain Follow is selected, the “Elevation Mode Select” menu will pop up, select online elevation model or local DEM file (Local DEM file name must contain “DEM.tif”, and be placed under the remote control Download folder to be recognized)

Input the survey area information in the Terrain setting menu, APP will automatically calculate the highest point and lowest point according to your flight, so as to judge if the lowest point and highest point could meet the project requirements.

• Click icon on the left to save flight.

“Strip Flight”
For Strip Flight, the selected points on map can be used to create a centerline, or KML file imported can be used to generate the centerline .

Select Import Coordinate Point, find the path where KML file is placed in the internal storage of the remote control, select corresponding KML file, select the points to me imported, select the elevation definition of the points, import.

Select appropriate flight speed and required single-side expansion width.

Choose to keep the centerline or not.
When obtaining the altitude of the takeoff point, the local DEM should be placed under the Download folder, and the remote control can be networked to obtain the aircraft position.

Same as “Mapping by aerial photography”, “Strip flight” can also select A/B/C/D positions to start flight. If the dynamic alignment flight is too close to the building, “Reverse Z” can be selected to change the alignment flight direction.

Import KML

Before using “Import KML” mode to create new flight, copy KML file to M300 remote control: local storage – 0 – Download path.

Open APP, click “Import KML”, APP will recognize KML file in the directory. Check the required KML file, click “Import”.

APP will automatically generate flight according to the imported KML file.
