The mapping and modelling software, DJI Terra, has released a new update, designed to enable the most accurate results in less time. Taking into account customer feedback, the new update DJI has developed introduces:
The merge of multiple point clouds
Using the new "Merge Outputs" feature in DJI Terra, you are now able to combine all the data into one point cloud when multiple scans of an area or object are performed.
Outputs supported include: PLY, LAS, and PCD formats
Improvements for the LiDAR point cloud process quality report
In the rare event your report of LiDAR point cloud missions is not up to standard, this new update enables you to discover the possible reasons for low accuracy or missing point clouds.
Known coordinate system database
When generating 2D and 3D reconstructions, you can now easily select vertical and horizontal coordinate systems by following the below path:
Reconstruction mission > advanced > Output coordinate system > Known Coordinate System. (Only applicable for the United States, Germany, Denmark and Japan).
In the Horizontal Datum Settings drop-down menu, select "horizontal coordinate system database" and "vertical coordinate system database". Type in the coordinate system name or authorization code, and select the desired coordinate system in the searching results. Then, click “OK”.
Seven-parameter transformation for 2D and 3D reconstructions
Whether you are mapping a large-scale or small area, the seven-parameter transformation process decreases the margin error between coordinate conversions, when the target coordinate system is unknown. This feature also serves to gain more accessibility to your 2D or 3D reconstructions models, to convert WGS84 locations used by GPS to local datum coordinates, and to transform LiDAR data into the local coordinate system through seven-parameter transformation.
You can use this feature by going to: Reconstruction Mission > Advanced > Output Coordinate System > Seven-Parameter Transformation. Moreover, you can either import files or type in coordinate information directly on the dialogue box, which we explain below:
