Abstract: Techniques are described for updating a digital twin of an environment, particularly, a digital representation of an object in the environment. A system can include a change-detection device having a camera, and one or more processors responsive to executable computer instructions to perform a method. The method includes capturing an image of a portion of the object using the change-detection device. The method further includes determining a corresponding digital data representing the portion in the digital representation of the environment. The method further includes detecting a change in the portion by comparing the image with the corresponding digital data. The method further includes in response to the change being above a predetermined threshold, initiating a resource-intensive scan of the portion using a scanning device, and updating the digital representation of the object by replacing the corresponding digital data representing the portion with the resource-intensive scan.
