DJI updates Terra for smoother, more accurate LiDAR mapping

DJI has released a new update for the Terra all-in-one drone mapping solution. Version 4.4.6 brings significant enhancements to LiDAR Point Cloud processing, promising users a more stable and accurate mapping experience.

For those new to DJI Terra, it’s a comprehensive software solution designed for drone-based mapping and surveying tasks. One of its standout features is the ability to process LiDAR data, transforming raw sensor inputs into detailed 3D point clouds. These point clouds are invaluable for various industries, including construction, agriculture, and urban planning, as they provide precise spatial information about the environment.

The v4.4.6 update focuses on refining the LiDAR Point Cloud processing capabilities. Users will notice improved stability during data processing, ensuring that large datasets are handled more efficiently and with fewer interruptions. This enhancement is particularly beneficial for professionals relying on consistent and reliable data outputs for critical projects.

In addition to stability improvements, DJI has addressed specific issues related to color rendering in LiDAR Point Cloud tasks. Previously, modifying the base station center point could lead to inaccurate color representation in the point clouds. With this update, such discrepancies have been resolved, ensuring accurate analysis and presentation.

Another notable fix pertains to the ‘Smooth Point Cloud’ feature. This function is designed to reduce noise and enhance the clarity of the point cloud data. Users had occasionally reported color inaccuracies when this feature was enabled. The 4.4.6 update rectifies this issue, allowing for smoother and more visually accurate point clouds without compromising on color fidelity.

For optimal results, users are encouraged to explore the various settings within DJI Terra’s LiDAR processing suite. Features like ‘Point Cloud Density’ allow users to adjust the sampling rate, balancing between processing time and detail level. Additionally, setting the ‘Point Cloud Effective Distance’ helps in filtering out unnecessary data, focusing on the area of interest. Enabling ‘Optimize Point Cloud Accuracy’ can further enhance the consistency of data collected at different times, ensuring a cohesive and precise point cloud output.
