The OPMMS® (Open Pit Mine Monitoring System) is a laser-measurement-based monitoring system, expressly designed for automatic and manual long-range profiling of open pits’ slopes and surfaces and other mining applications, specifically customized for different terrestrial laser scanners as Teledyne-Optech ILRIS or the RIEGL VZ Series. The platform automatically compares the acquired scans to a reference scan, taken as baseline, and detects displacements and deformations. The laser scanner readings in the assigned regions of interest are inspected against the base measurements and an automatic report is generated.


  • Main users
    1) Mining SafetyMonitoring Sessions continuously acquire the investigated area and detect changes over a predefined threshold, performing a discrete protection system for employees, machinery and equipment.2) Variation and Production MonitoringThe system detects variations with respect to a predefined reference scan (baseline) and optionally with regards to an intermediate reference scan. The whole scanning sequence is archived and can be analized in the Gexcel point clouds processing suite for volume calculation and data comparison to previous surveys.3) Landslide Monitoring with AlertLandslide and critical areas can be continuously surveyed and compared. If movements surpass a defined threshold, automatic alerts warn workers and the site responsibles.

  • Data description
    Real-time 3D Monitoring Terrestrial Scan Data: 3D point clouds, images, statistics and visual outputsScan data and images are taken by means of an automatic monitoring web application software, OPMMS®, that can be managed locally or remotely. Raw and processed data are archived, together with analysis reports and statistics.
  • Data collection description
    Scans are taken using high grade, long range, high precision terrestrial laser scanners such as Optech ILRIS or Riegl VZ-Series models. Data are captured and saved in the proprietary laser manufacturer format and immediately converted in the Gexcel application structured format, then filtered, processed and compared by a 3D inspection in order to detect differences toward a reference scan. The time series of the acquired scans is saved and archived, so that it can be subsequently imported in the point clouds Gexcel processing suite for further analysis and computations.High resolution photos are captured as well and linked to the 3D scans for a deeper qualitative investigation.A rugged control unit is provided with power and communication interface included.Several Useful Accessories & Options are available.Fully Supported Hardware/Software: We care of hardware, accessories and software integrity.
  • Data quality control descripton
    External quality control in not implemented yet. Otherwise a robust and precise scan alignment algorithm is used to minimize potential misalignments between compared scans due to ground stations or atmospheric variations that can happen when long range scanning is performed.
