HD photography and laser scanning revolutionises asset integrity reporting

Project Summary

Global Design Innovation (GDi) approached NZTC with a proposal to develop a software package that could interrogate HD photography and laser scanned cloud data to allow automated coating and corrosion mapping, crack detection and dimensional surveying – potentially transforming the entire asset integrity management process.

Due to the novel aspect of this technology, it was proposed that a feasibility study was carried out to define the specification of the software and provide a detailed development plan for phase two.


Industry value:
This revolutionary technology could refine and reduce the need for on-site inspection requirements and has the potential to the reduce the overall inspection delivery costs by 40%.

Key results:
By using state of the art laser scanners and point cloud data, the study investigated the suitability of these inputs and custom software development to aid the increased accuracy, speed, and repeatability to allow corrosion/coating scaling and mapping and crack detection.

The key results from the feasibility study confirmed a software application could be developed to achieve the output goals of using HD photography and laser scanned point cloud data, to allow automated coating and corrosion mapping, crack detection and dimensional surveying. The feasibility study allowed the idea to be taken to a stage whereby it was deemed to have suitable potential and phase two was defined.

Lessons learned:
This study was used to develop the proof of concept, which was fully proven. The funding allowed the time to further refine the idea and explore the technical aspects of the point cloud data, to progress the full project proposal and move forward to develop the technology. Subsequently, the development of phase two commenced.
