Description

Real-time field work monitoring method and system {SYSTEM AND METHOD FOR REAL-TIME MONITORING FIELD WORK}

The present invention relates to a method and system for real-time field work monitoring. In more detail, it relates to a method of monitoring field work in real time by controlling a camera system placed on the site through a digital twin that matches the site to a three-dimensional virtual space.

With the increasing digitization of manufacturing processes, the concept of a digital twin that creates a digital image of a real object or process in near real-time on the job site is attracting attention. Digital twins allow you to have a digital footprint of the entire product, from design and development to the end of the product lifecycle. By using this, you can understand not only the product itself as designed, but also how the product is used in the system and field that manufactures it.

A digital twin is defined as an evolving digital profile of the past and present activity of a physical object or process that helps optimize business performance. Digital twins are based on large-scale, accumulated real-time, real-world data measurements that span multiple dimensions. Based on these measurements, companies can create evolving digital profiles of objects or processes to gain insight into system performance or to take physical actions, such as changes to product design or manufacturing processes.

The true power and importance of digital twins lies in providing a comprehensive, near real-time connection between the physical and digital worlds. This has the advantage of enabling fundamental design and process changes that are not possible with conventional methods.

Meanwhile, various image sensors such as an omnidirectional camera, a PTZ camera, and an infrared camera may be disposed at a work site such as a factory.

However, in order to remotely monitor the current site, only a remote monitoring system that simply lists and displays the images captured by numerous image sensors placed on the site is built, so that the area or situation that the remote manager wants to monitor can be monitored using the remote monitoring system alone. It is difficult to ascertain.

In addition, there is a need for an interface for effectively controlling a large number of cameras of various types by a small number of remote administrators.
