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.
 

CONSTRAINT TOOL












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!

CHANGE DETECTION MAPS

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.

CLOUD SHARING

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.

JRC 3D RECONSTRUCTOR SUCCESS CASE — EARTHQUAKE DEFORMATIONS CHECK

RESTORATION AND CONSERVATION INTERVENTION Temple of Belén, Cusco (PERU)

PDF versione italiana

PROJECT DESCRIPTION

KEYWORDS: Architectural | Conservation | JRC 3D Reconstructor | Laser scanner


The church of Belén stands on a strongly seismic territory that from its origins has undermined the structure, rebuilt several times. After the damages caused by the earthquake of 1950, the internal consolidation of the vaults and domes was carried out, in order to avoid subsequent collapses, and only recently (for the first time!) a laser scanner survey was commissioned by the Ministry of Culture in Cusco to evaluate the actual structural conditions of the church and undertake restoration work. Thanks to this important technological step, it was immediately possible to notice some serious structural problems concerning the subsidence of the cupola. An aspect that would never have emerged with traditional measurement systems.

NEEDS AND GOALS
  • Measure, analyze and document the phenomena of the degradation of the church useful for the restoration project.
  • Get for the first time an accurate survey to obtain a full view of the building.

JRC 3D RECONSTRUCTOR SUCCESS CASE — NON-INVASIVE ARCHITECTURAL DIAGNOSIS

ANALYSIS AND CAD REPORT OF AN ANCIENT STABLE Rustic Court “La Faggiola”, Piacenza (ITALY)

PDF versione italiana

PROJECT DESCRIPTION

KEYWORDS: Architectural | Conservation | JRC 3D Reconstructor | Laser scanner

Fig.1_Picture of the building and CAD redrawing with high-resolution coloured orthophotos

The “Faggiola” Rustic Court is an ancient private residence (now public) dating back to the early twentieth century. Having been neglected for a long time, the client decided to check its status by relying on 3D surveying technologies, before proceeding with redevelopment works and refurbishment and restoration interventions. During the days on the field, we worked with laser scanner instruments and it was possible to detect the geometry of the entire building: from the external areas to every single room, obtaining the highest precision necessary for the graphics redrawing. The material components of the building have been of great importance: building and finishing materials, signs left over from the passage of time, have contributed to a greater understanding of the building's real conditions. The methodology used, fast and non-invasive, is suitable for completing architectural diagnoses of buildings and defining the type of interventions to be carried out, be it demolition or restoration.


NEEDS AND GOALS
  • A detailed survey of the external and internal environments of the building.
  • Graphics rendering of the exact geometry of the building (plans, sections, and elevations) and material components.
  • Future restoration and conservation interventions.
