3D Point Cloud
The 3D Point Cloud presents profile point data that can be rotated in three dimensions.
Description
Image
Profiling mode allows you to view a real-time 3D point cloud of the sea bottom or structures under the water. The profile point data can be exported to a file so that third-party software can extract depth, distance, and volume measurements.
Tip
In the Profiling Settings dialog box, you can choose to display only the sonar view, only the 3D Point Cloud, or both. If you can’t see the 3D Point Cloud, ensure that either Image and Profile or Profile Only are selected. You can also change the point cloud display parameters in this dialog box.
To change the depth range settings in the 3D Point Cloud window, click Depth, uncheck the Adaptive Palette box, enter the top and bottom depth, then click Apply. To change the colour scale of the 3D Point Cloud, click Depth, check the Adaptive Palette box, then click Apply.
The following controls can be used in the 3D Point Cloud window.
•  Use the mouse scroll wheel to zoom in or out.
•  To rotate the point cloud, press and hold the left mouse button, then move the mouse.
•  To clear the point cloud, double click the right mouse button.
The following buttons, found in the top-right corner of the 3D Point Cloud window, offer different views and measurements. The currently selected view or tool will be underlined.
Image
A Project view: An isometric view where you can rotate the point cloud in three dimensions.
B Top view: A top-down view where you can measure distances or place target markers.
C Side view: You can see the elevation of the points in the side view.
D Marker: Click to select this tool in the Top view, then click anywhere in the 3D Point Cloud window to place a target marker overlay. You can place as many markers as you need.
Note
Georeference information on each marker will be added to a “.kml” file in the folder “C:\KML\M3_V0253\Recordings”.
E Tape Measure: Click to select this tool in the Top view, then click and hold the left mouse button and drag the mouse to measure distances.
