Rescanning to Update Digital Twins

Explore how NavVis streamlines updates to digital twins with an efficient rescanning workflow, ensuring accurate, cost-effective realistic representations.

Change is inevitable. Our world, buildings, factories, shop floors, process facilities are bound to change – driven by a consistent need to improve. This poses a challenge for decisions makers on how to make informed decisions when the physical fabric of factories are constantly changing.

Basing decisions on unreliable layouts or old CAD data can result in delays and extra costs. Realistic digital twins address this challenge and enable factory planners and engineering departments to better understand, and collaborate, based on actual site conditions. But to maintain its value a digital twin needs to stay up-to-date and reflect the as-is reality. Thus, the need for keeping data up-to-date – rescanning as we call it.

Without rescanning, future changes to the physical world will not be represented in the digital world – the physical world and the digital world do not automatically stay in sync. The challenge is more pervasive, as a change to just one part of the as-is reality reduces the reliability of the whole digital twin. This creates a scenario where small as-is changes collectively diminish the value of the digital whole. Reliable up-to-date spatial data, therefore, requires a lean rescanning workflow that captures the relevant changes and avoids the costs and delays required by rescanning entire facilities.

In this regard, NavVis provides a novel, cost-effective, and efficient rescan process that combines the speed of survey-grade mobile laser scanning with an intuitive cloud-based workflow that processes, anonymizes, publishes, and displays the best quality data.

Empowering planners and engineers to systematically update their digital twin with NavVis reality capture services or on an ad hoc basis. Additionally, it allows users to take advantage of shorter production stops, which is especially valuable given the current high-pressure production environment. In certain cases, the simplified nature of smaller scans and the NavVis enhanced rescanning workflow empowers local teams to perform these tasks independently. This ultimately provides end users with spatial data they can trust and the confidence to make informed decisions based on relevant as-is conditions.
