iMetrum video monitoring – “a big leap forward”

iMetrum structural monitoring technology

Recently Traverse magazine, the publication for the Institute of Surveyors Victoria, interviewed DataHawk for an article about iMetrum video monitoring and hailed it a big leap forward in monitoring technology.

IMetrum is a cost effective, completely passive, video monitoring solution that leads to less time on site and no need for mounting GNSS receivers or prisms in hard to reach areas. This is all while achieving accuracies down to 0.01mm and measurements of 0.5mm from a kilometre away. And, because it takes measurements up to 300 times per second and can measure 200 points simultaneously, you can accurately monitor a structure even when there are multiple dynamic forces in play. Add to that the benefits of being able to store the video and archive it so further measurements can be pulled out at a later date, or to use as a visual aid, iMetrum is a very exciting advancement in monitoring technology.

To use the system, all you need to do is:

  1. Set up the camera
  2. Choose the quality of the image
  3. Pick the points of interrogation – these need to be features that are defined or have contrast e.g. a bolt or a paint line
  4. Capture the video
  5. This is automatically loaded into the iMetrum software which then uses pattern recognition technology and sub pixel interpretation of the video images to display the displacement
  6. of the structure down to 0.01mm at over 300HZ

Rail tamping just got better for Leighton Swietelsky Rail

Trimble Gedo CE for tamping

DataHawk is proud to announce that the first Trimble GEDO Vorsys Rail Survey Solution in Australia is now in customer hands.

In mid-2013, DataHawk delivered the first GEDO Vorsys system in the southern hemisphere to Leighton Swietelsky Rail (LSR), who were at the time operating in the Upper Hunter control region. Leighton Swietelsky is a joint venture between Leighton Contractors and Swietelsky to offer highly mechanised track maintenance and renewal in Australia – read more about that here.

Integration of this state-of-the-art rail technology into the LSR rail tamping process will assist their highly experienced crew in creating efficiencies in pre-project planning, rail tamping outcomes and final project handover documentation. Initial LSR projects targeted for integration of the Vorsys system include a 48 kilometre rail maintenance tamping project being undertaken for the ARTC in the Wagga region.

The Trimble GEDO Vorsys Solution allows for fast, accurate measurement of track condition – for both pre and post rail tamping survey – resulting in a significant productivity gain over other existing systems. The collected data is easily interrogated and interpreted by tamping crews, allowing for seamless on-site delivery into their onboard WIN ALC control system, increasing productivity and machine utilisation by around 30 percent. The precision and usability of the system makes it an ideal tool in conventional and high speed rail tamping.

Joerg Schnabel, Technical Director for LSR, says of the system, “Incorporating the Vorsys and GEDO Tamp software into our rail tamping procedure results in significantly improved tamping ability and track quality at handover. The Front Offset (.vers) files produced are fed directly into our onboard control and allow for automation of the tamping process giving a very high quality result.” [Story continues under image.]

Structural monitoring – measure 200 points simultaneously without 200 prisms

iMetrum video monitoring - DataHawk

If you’re in the game of using technology for structural monitoring for things like deflection, strain, rotation and displacement, you’re probably familiar with the traditional method of using a total station and prisms. If you are, you’ll know that it’s a fairly arduous process, mounting targets on the structure and measuring each point one-by-one. It’s also near impossible to measure the trend of deflection in that structure when it’s under load – think monitoring a bridge with a train actually running over it.

At DataHawk we’re pleased to say that we have a solution that hits this traditional method of structural monitoring out of the park – iMetrum video monitoring.

iMetrum is a cost effective, completely passive, video monitoring solution that leads to less time on site and no need for mounting costly prisms, all while achieving accuracies that are unobtainable using traditional methods – down to 0.01mm. And, because it takes measurements up to 300 times per second and can measure around 200 points simultaneously, you can accurately monitor a structure even when there are dynamic forces in play.

Add to that the benefits of being able to store the video and archive it so further measurements can be pulled out at a later date, or to use as a visual aid, iMetrum is a very exciting advancement in structural monitoring technology.
