I’ve seen a lot of technological advancements in land surveying and civil engineering over my career, including electronic distance measurements, GPS, and robotics to name a few. Now we are starting to see merging of real and virtual worlds on construction sites, called mixed reality.
According to Wikipedia, mixed reality is “the merging of real and virtual worlds to produce new environments and visualizations where physical and digital objects co-exist and interact in real time.”
Below is a video from Trimble demonstrating their mixed reality system, displaying holograms of 3D design models at a construction site. For more information, visit Trimble’s website: https://mixedreality.trimble.com/
