Program Management#
In the "Log" tab, login records can be viewed.In the Log system tab, real-time recording of system status and key operational events enables monitoring of operational conditions and detection of abnormal signs.In the Log Audit tab, you can check the access log from any members.
GUI (Graphical User Interface)#
Once the sensor connection is completed, click on “Viewer” in the top left corner to start using the program.
The registered areas and the associated clients are displayed on the left side. Select the client to control.
If the sensor is successfully connected, the point cloud will be displayed.Click and drag with the left and right mouse button to adjust the position and orientation of the viewer. Press 'v' to switch views (XY view, XZ view, YZ view).1.
Click on the gear icon located at the top left corner to initiate the GUI.
You can toggle each function using the button next to each feature.

2.
Click on the “Calibration” button to modify the coordinate system of the viewer.
3.
Click on the sensor to calibrate and adjust each calibration variable.
Press the left and right mouse buttons to navigate the viewer’s position and direction.
X, Y, Z : Position of the sensors in the coordinate system (1m per grid cell)
Roll : Rotation angle of the sensor with respect to the X-axis
Pitch : Rotation angle of the sensor with respect to the Y-axis
Yaw : Rotation angle of the sensor with respect to the Z-axis
Deactivate all other sensors except the first one, which will serve as the reference.It is recommended to deactivate the "Object" during calibration.
To adjust the yaw parameter, press the 'V' button to switch the view to 2D.
Align the point cloud data parallel to the x axis. It is recommended to arrange to be longder in the x direction as shown below.
Adjust the roll, pitch, and z parameters switching the view to yz and xz.
Refer to the images belowe for guidance.
Save the calibration status once completed setting.In order to calibrate the second sensor, change the point cloud color to easily distinguish the PCD (Point Cloud Data) of each sensor.
Activate the reference sensor(the first sensor, which has been completed calibration) and the second sensor (currently being calibrated). Switch the view to 2D and adjust the x, y, and yaw parameters to match to the reference sensor.
Adjust roll, pitch, and z parameter switching the view to yz and xz.
Refer to the below image for guidance.
Save the calibration status once completed the settings.In order to calibrate the third sensor, change the point cloud color to easily distinguish the PCD of each sensor.
Activate the reference sensor and the third sensor (currently being calibrated). Adjust each parameter in the same way as above, using the reference sensor as the basis.To return to the initial state, press the “Reset” button.
Once completed calibration adjustment, press “Save” to maintain the current state.Click on the “Export” button to save the adjusted calibration values and click on the “Import” button to load previously saved calibration data.Also you can use the calibration guide in the menu.5.
For ROI setting, click on the “Zone” button and select “ + Add Zone ”.
6.
Click on the "Add zone" button to draw the Zone.
GPS Calibration#
Use GPS Calibration to visualize LiDAR data in conjunction with real-time Google Maps coordinates. This allows you to intuitively verify detected objects within their actual surrounding environment.2.
Right-click on the location for which you want to obtain the coordinates, then select "What's here?".
3.
Click the generated location marker to view the latitude and longitude of that point.
(Example: Latitude: 37.010105, Longitude: 127.219063)
4.
In the Viewer, enable the Map feature, then click the "GPS Calibration" button and enter the latitude and longitude values obtained from Google Maps.
5.
Adjust the Heading value to rotate the map clockwise or counterclockwise. Align the map approximately with the orientation of the displayed PCD data. 6.
Fine-tune the position by making small adjustments to the latitude, longitude, and heading values. Use nearby buildings, roads, and vehicle traffic patterns as references. For more precise alignment, enable the 3D view and use the three-dimensional representation of surrounding structures. Data Logging and Playback#
1.
Press the red circle button at the top left corner to initiate data logging.
Set the Record Time and File chunk size using the mouse scroll, then press the OK button to start recording. Set the File chunk size for smooth recording and playback. The default value is 5GB.
To change the logging file storage directory, modify “oslo_storage_path” in /opt/oslo/.env.json file.2.
Press the folder icon at the top left corner to load and playback the saved logging data.
3.
Use the activation button at the top left corner to display or hide the point data of each sensor.
You can adjust the playback speed by pressing “Play Speed” button in the bottom right corner.
To return to real-time monitoring, press the stop button to end playback.
