Reconstruction Procedures
Follow the steps below to reconstruct point cloud data in DJI Terra.
1. Launch DJI Terra, select New Mission or Import to create and save a point cloud processing
task.
2. Select on the task editing page and import the folder from the microSD card. The folder
will be named according to the time the point cloud data was recorded. The folder contains
les with the sux CLC, CLI, CMI, IMU, LDR, RTB, RTK, RTL, and RTS.
3. Congure the point cloud density and output coordinate system settings.
4. Advanced Settings
a. Ground Point Type: check the Ground Point Type and select the Ground Type based on
actual needs. Flat Ground is suitable for areas with dense buildings or plains. Gentle
Slope is suitable for areas such as common mountains and hills. Steep Slope is suitable
for areas with great elevation changes such as mountains and valleys.
b. Generate DEM: click to generate DEM output. Select By Scale or By GSD to set the
resolution of the output.
5. Tap Start Processing to start reconstruction and wait until it is completed.
6. View the point cloud results in dierent coloring modes.
RGB: displays based on true color.
Reectivity: displays the corresponding color based on the object’s reectivity, in the scale of
0-255. The range of 0-150 corresponds to diuse objects with a reectivity of 0-100%, while
151-255 corresponds to fully reective objects.
Height: displays the corresponding color according to the height of the target.
Return: display the corresponding color according to the number of returns when collecting
data.
Type: displays the ground points and points not categorized if Ground Point Type is selected
before processing.
