PRESS RELEASE — GEXCEL HERON 3D Mobile Mapping: Improvements in Accuracy and Usability

 Gexcel HERON software improvements

Brescia, Italy, January 12th, 2023

The recently released versions of HERON processing software(s) make HERON 3D mapping projects more accurate, effective and usable thanks to important improvements in the usage of ground control points, in the change detection workflow, and for the cloud-sharing process.


Several ways to constrain and geo-reference HERON trajectories.
Ground Control Points (GCPs)
- Measuring GCPs directly in the field by using HERON and a calibrated pole or
- Identifying CGPs on the HERON point cloud.
GCPs local coordinates are automatically paired with the related global coordinates.
Point Clouds and Scans
Static scans or portions of 3D point clouds previously acquired also with different sensors (UAV, mobile scanners, mapping systems, photogrammetry) can be used as constraints as well.

Constraint procedures play a crucial role to improve the quality of the final trajectory!


HERON - Change Detection Map

1. Use a point cloud or BIM model as a reference map.
2. Let HERON self-locate with respect to the reference.
3. Produce a survey aligned with the reference map.
4. Detect changes that occurred in the time.
5. Automatically get the change detection map for further editing.


Mobile mapping is dramatically speeding up the process of capturing 3D and image data. This should be matched by the speed of project delivery and online procedures.

To increase Site to Sight of data efficiency, GEXCEL customers can now link up with 3DUserNet to get a special free annual subscription to the VISION platform with a direct workflow from Reconstructor to 3DUserNetVISION. This will enable users to deliver more efficiently for their customers – with the opportunity to upgrade to a full subscription at a substantial discount at any time.

HERON portable mobile mapping - stockpile volume computation - Feralpi Group

HERON MS TWIN-metal stockpile 3D mapping

Feralpi has set itself the goal of introducing advanced systems to monitor and verify the flows of raw materials and by-products of the steel mill, in order to optimize its production process.
Feralpi has chosen HERON technology because it fits their different needs. On one hand, the need to periodically obtain the volumes of the scrap stockpiles stored on a large area of the plant; on the other hand, the need for a high speed of scanning and results delivery, ensuring the required accuracy.
The project involves a monthly survey of the material stockpiles with HERON portable laser scanner technology.
During the 3D modelling phase, the stockpiles are isolated from the structural elements of the plant to define their volume.
The day after the measurement, a technical report with the measurements of the overall volumes is provided to Feralpi.
Thanks to this technological improvement, Feralpi is experimenting with a more efficient approach to the management of raw materials at low costs.

  • To monitor and verify the flows of raw materials and by-products of steelworks by using advanced systems.
  • To optimize the production process.

« Thanks to HERON technology we are able to map our material parks in a short time and with high precision. »

              • Colour mapping tool: overall improvements of the colour mapping dialogue: fast colourization and histogram computation; more flexible Min/Max mapped input fields allow to enter out of range values, Reflectance, Confidence, Curvature and Ambient Light colours excepted; visibility property in the 3D scene is updated while switching from one colour layer to another.
              • Model selection tool: changed the commands “select models in this frustum”, “select meshes in this frustum”, “select clouds in this frustum” and “select projectors in this frustum” to perform a real selection according to a camera field of view, instead of activating the items checkboxes.
