Monitoring Buildings and Structures in 3D
Motion capture systems are typically defined by how they capture
human motion. In reality, the systems track anything that has a marker on it.
Portable, wire-free systems such as the Moiré Phase Tracking (MPT) camera
systems from Metria Innovation can monitor and report critical information for
industries outside of human study and the
confines of a lab or studio. Take the building and construction industry, for
example.
The building and construction industry is reliant upon the
structural integrity of the projects it completes — whether it is a building, a
bridge, or storage structure. Most movements
detected in any of these structures is a sign of deterioration and needs to be analyzed
to determine the best approach for repair.
Displacement sensors are commonly used in construction site
supervision for this purpose, but only collect data in 1D or 2D. Tracking
motion in 3D enables the user to digitally recreate the entire structure. With
this perspective, motion capture systems can supply real time data on a
building’s stability during and after construction, as well as its ability to
weather a range of conditions throughout its
life time.
In
addition, in the case of a catastrophic circumstance, this same real-time data
can assist with restoration by providing clear and concise information
concerning the stability of the remaining structure.
The Problem: The need for
real-time data and sensing of ongoing or potential building deformations to
prevent concerns or issues with building stability.
Current motion capture systems designed to monitor deformations, both onsite
and offsite are:
- Limited in sufficient detail to detect micro
deformations and vibrations caused by structural defects
- Limited in sensing and alarms outside of
environmental causality.
- Required to employ expensive sensor
technologies as accelerometers, laser emitters, and acoustic wave
generators.
- Limited to single point determinations or
collated data from caches of single data points.
- Time-consuming and manpower intensive
- Limited to providing short-term data only.
The Solution: Combining motion
capture technology with computer vision techniques and systems to provide
non-contact monitoring both during and after construction.
By engaging current high speed and highly accurate motion capture
technology and employing enhanced computer vision techniques, it is possible to
collect real-time motion data of structural vibrations. These vibrations are
caused by microscopic defects in both building materials and building
structures.
And with 3D motion capture systems like the MPT technology, which are
portable and easy to use, municipalities, building owners, and construction
companies can provide a 24/7 safety measure with little manpower or
complication.
