3D Laser scanning in monitoring with the Leica MS60 MultiStation - Transportation Monitoring, Bridge Monitoring

Leica Geosystems’ scanning in monitoring solutions are used by surveyors and organisations across the world to measure the potential impact of nearby construction and natural hazards on buildings and infrastructure.

From monitoring the safety of a commuter rail line in Dublin to surface deformation in Singapore, every project presents unique challenges and opportunities for surveying service providers to develop and expand their services, backed by Leica Geosystems’ expertise and innovations in precision measurement technology.

The revolutionary merging of Leica Geosystems’ 3D laser scanning and automated total station technologies has led to a significant advance in monitoring capabilities. For example, when detecting road movements using single reflectorless points, incorrect results may occur from live traffic interruptions. Laser scanning overcomes this problem, as data-rich patch scans provide accurate surface measurements of busy highways, increasing efficiency and safety without the need for road closures or diversions. Contractors tasked with monitoring busy highways during construction benefit from the method to continuously collect data without halting the flow of traffic on always busy roads. With limited access to the road and the safety of drivers and staff a priority, the monitoring system is fully remote and can run autonomously 24/7 over several years.

Scanning in Automated Monitoring – A Unique Solution

Automated monitoring with Leica Geosystems’ 3D laser scanning was introduced in 2013 with the launch of the Leica Nova MS50, the world’s first MultiStation, a robotic laser scanning total station. Updates to functionality and scanning capability heralded the release of the Nova MS60. Used in conjunction with Leica Geosystems’ GeoMoS software suite, this remains the only automated scanning solution available for monitoring.

Using automated total stations for prism and reflectorless measurements to define points plus 3D laser scanning on focused areas of interest provides an optimal, data-rich perspective for monitoring deliverables. This enables businesses to stay competitive by expanding their portfolio of services to include measurement of hazardous or previously inaccessible areas.

Automated monitoring projects typically use prisms outside the area of deformation as survey control and inside the area to track movements of specific points. By incorporating 3D laser scanning to the workflow it is possible to read between the lines and compare timed measurement scans with baseline reference datasets, enabling autonomous deformation detection. Notifications can be triggered and instantly communicated to decision-makers if tolerance thresholds for movement are exceeded, and corrective action required.

3D laser scanning brings versatility to monitoring projects, significantly enhancing data collection compared with the single reflectorless measurement technique. Mass data from scans adds reliability and quality assurance to a project.

Scanning in monitoring solutions are rooted in Leica Geosystems’ product development innovations for the acquisition, management and analysis of geospatial data. Every monitoring project might differ in scope, environment, and type but the requirement for accuracy and reliable information is always vital. The addition of 3D laser scanning, together with Leica Geosystems’ support and training, delivers an unsurpassed option for enhanced and comprehensive monitoring, and here’s why:

1. Simple and Quick to Set Up

The MS60 is a total station and a laser scanner in one instrument, therefore measurements to an infinite number of targets are possible and recorded data is not limited by the number of prisms and reflectors. With the Leica MS60 and the GeoMoS monitoring solution, the area to be scanned is defined by shape, size and frequency. There is no need to find discrete points or seek access to install additional prisms as measurements are taken via scans, saving time and costs. Scanning provides a reliable contactless and non-intrusive solution for an increasing number of monitoring projects and is especially useful in situations where installing prisms would be impractical, dangerous, prohibited, costly and potentially damaging.

2. Easy to Maintain

Scanning optimises the number of prisms required so saving time and money on installation and checking and cleaning during operation. It is also a non-invasive technique so when the job is completed, the de-commissioning process is straightforward and fast. With fewer prisms to remove and no surface damage to repair the monitoring instrumentation is available, portable, and ready for use on the next project.

3. Comprehensive and Reliable Data

Unlike single reflectorless measurements, the MS60 can define a scanning patch of an area to be monitored and capture thousands of points per second. With this amount of data, GeoMoS automatically calculates the median value of the patch using special algorithm technology. In addition, the Leica MS60 has a high-resolution dual-camera imaging system which can automatically capture images with each scan. MS60’s sensor fusion allows monitoring professionals to visualize deformation information in GeoMoS, including heat maps, graphs and tables and to make informed decisions as required.

4. Optimising Your Investment

The MS60 with GeoMoS scanning module is an empowering, multi-functional combination for enhanced data capture. Frequently, monitoring projects require hybrid measuring techniques so the solution can be used for prism monitoring only, or a prism plus scanning option at any stage without the need for further investment in additional hardware. Even when a project requires scanning of unplanned areas the MS60 takes just minutes to define a patch and be automatically incorporated into the monitoring workflow. The versatility and flexibility of a monitoring solution incorporating scanning is scalable from short-term projects, to software options developed for advanced monitoring initiatives using different sensors.

5. Data-Rich Results

The MS60’s advanced sensor technology merges automated scanning, imaging, reflectorless and prism measurements, providing holistic information for accurate detection of movement with GeoMoS. The quality of monitoring data is critical to better understand the impact of deformation, and having the capability to produce such a data-rich output increases confidence in the reliability of the results.
