Green Challenge Innovation Award pitch

By Nige Austin - Posted

Radar Portal Surveys pitches its High-Speed 3D Ground Penetrating Radar in this video in order to secure funding to finalise commercialisation and distribute the product to the world market.

The Postcode Lottery Green Challenge is the largest annual and international green business plan competition. The winner gets 500,000 EUR to help bring her or his plan to market.

This fantastic initiative was instigated by Bill Clinton a decade ago, and has facilitated a range of innovative products like ours to break into the international market in order to commercialise solutions which benefit the planet through Green and C2C principles.

Radar Portal Surveys have invented a High-Speed 3D Ground Penetrating Radar (GPR) which is a unique non-destructive testing methodology which facilitates improved road performance.

With 65,000,000 km's of roads worldwide, and being the largest expense for many council's, we estimate a 19% road budget saving pa through sustainable road maintenance and rehabilitation programs.

For the last 10 years we have developed a new category of radar which far outperforms the existing 30 year old technology. Working with us we have a network of industry leaders from Main Road Authorities to NASA signal scientists.

We have completed 220 Projects and collected 25,000 km's of data. We have set up a supply chain of manufacturers and distributors.  The laser cuttings have just arrived for the latest iteration which will fit into 2 hard cases for easy transportability. The GPR will be able to be assembled in 10 minutes ready to start sub-surface data collection of roads, bridges, airports and ports at 100 km/h.

We own 100% of the company and have survived through service provision to the local market with our technology. Our 5th generation technology starts testing next week and a unit is being delivered to Japan for research next month.

We need to secure this Green Challenge Award so we can finalise the commercialisation of our product in order to move into a scalable C2C lean manufacturing model which will supply the equipment to the global market.

Planned future versions will ship only our GPR modules and control units and we will provide CAD files which partners can then 3D print using waste products like aluminium cans and plastic reduce the carbon footprint.

We are Radar Portal Surveys, and with the assistance from Post Code Green Challenge we will survey they world's roads.

We'd love to hear your feedback!

Thank you.

PaveScout Surface Imaging System

By Nige Austin - Posted

The PaveScout System combines a total set of surface and asset imaging technologies allowing a complete visual capture the road environment. It includes a new patented high-speed surface imagery unit for crack detection, laser profiling units, and point lasers for rutting and roughness with high-resolution asset cameras all linked to a precision positioning and triggering system. The advantage to the road authorities, is the quality data allows a better understanding of the road pavement condition. Producing the standard measurements of the road surface degradation, the PaveScout can also detect other road distress criteria such as; road cracking, road geometry and even detect road surface change over time.

The PaveScout is unique, and is ideal for network level assessment.

Features of the PaveScout are;

  • High-Resolution Surface Imaging System using a line scan camera with patented photometric lighting.
  • Rutting Lasers and Cameras produce 2048 points across a 4 metre lane width.
  • Texture Point Lasers.
  • Four Panoramic Environmental Cameras (each with a resolution of 5 megapixels).
  • A Dual-Frequency GPS System integrated with the Laser Ring Gyro Inertial measurement.
  • Wheel Encoder for Chainage Measurement.

The PaveScout uses two high-power line generating lasers, in combination with high-speed, high-resolution laser cameras to measure the profile of the road surface over the full lane width of four metres. This system is used to determine the rutting, texture depth and roughness measures. Each of the scans can be meshed together to produce a topography model. Rutting is determined using the 2048 point laser profiling system for the entire four metre scan width.

The system complies with Austroads Standards and can be configured with a number of different algorithms including; fixed,  straight-edge, sliding-straight edge and taught-wire methods. Roughness measures are extracted from the PaveScout laser system which produces a highly accurate profile in the direction of travel. A six axis laser gyro inertial measurement system is combined with a GPS system to determine the full flight path of the vehicle. The result is a far more precise detection of position. When this is combined with the laser profiling data, the full road geometry can be obtained.

Texture depth is measured, using both the laser line profiler and point lasers. The system allows calculation of sensor-measured texture depth, and mean-profile depth as per the Austroads and ASTM standards. The PaveScout uses the detailed surface imaging system to transversely position the high-density laser within each lane, correcting for driver position error. RoadLoack also enables change in the road surface, from one year to the next to be determined using these aligned line scan camera images. For historical purposes the system incorporates two conventional point laser units to enable data to be provided in the more traditional way. The PaveScout system is validated in accordance with the Australian standards. Repeatability and bias is determined for each driver as per the standards. The four 5 Megapixel cameras fitted to the PaveScout offer digital imagery for asset detection and can be displayed in both the Portal 4D software package and in the Web Data Viewer.

The PaveScout achieves full crack mapping and condition assessment across the full line width with the unique photometric lighting system. Artificial lighting achieves a one millimetre surface resolution with one 4 metre wide camera image. Post-processing of the data allows the quality to be verified. Surface defects displayed in the surface image can be linked to the laser profiling system outputs, allowing improved understanding of the surface defects across all features of the road. Using photometrics, the visual components of the road can be separated from the structural components of the road surface. Within the resultant images, cracking and other road defects become far more obvious, easing the tasks of crack detection and automating the process.

Surface defects are extracted from the photometric images into crack times and fed into a severity rating. The resultant automated crack maps are reviewed by data analysis technicians to ensure quality crack mapping is produced. The results can then be exported into PDF based maps, excel tables, or geospatial data formats, or customised for specific database systems. The Portal 4D analysis and reporting package is a total road environment recreation package. It allows the user to manage the data and to view all features in the one package. High-level functionality has the ability to view collected data, view automatically extracted features, tag extra features, graph road conditions and generate reports. Portal 4D complements existing PMS and road management systems by providing more detailed analysis.
