HERON SUCCESS CASE — VOLUMES OF SCRAP METAL STOCKPILES

THE PRODUCTION PROCESS OPTIMIZATION IN A STEEL PLANT 

Feralpi Group – Lonato, Brescia (IT)

PDF versione italiana

PROJECT DESCRIPTION

KEYWORDS: Steel plants | Volumes computation | Stockpiles | Heron | 3D Mapping


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.


NEEDS AND GOALS
  • 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. »

              Reconstructor® 4.2 makes a step forward into the processing of large datasets from various 3D sensors and in particular from Mobile Mapping Systems. Reconstructor® 4.2 increases the capability to manage data from tunnels, underground and open-pit mines 3D surveys, thanks to new and improved tools that help users get the result done by a smart process.

              Following, a selection of some new key functions introduced in Reconstructor® 4.2:
              • Tunnels, underground and open-pit mines: easy extraction of sequential cross-sections along tunnels axis; measurement of areas and volumes along tunnels; creation of DEM (digital elevation models) starting from 3D point clouds; straight workflow to extract isolines and contours from open-pit mine models and DEMs.
              • Terrain models, buildings and infrastructures: orthophotos can now be used to quickly and efficiently create facades' depth maps. This function can be used also by final clients thanks to the new GoBlueprint free tool. Also, the procedure to extract, display, measure, and move to CAD profiles and cross-sections is now faster and more efficient.
              • Vegetation: colour mapping for point clouds classification and to support the vegetation removal process.
