There has been much work on Scan-vs-BIM, and it has implications on construction productivity, quality, and safety. However, these methods need to be extended /altered to do real-time Scan-vs-BIM. This paper presents the extensions for existing methods such as registration, point matching, object detection, and pose estimation to cater to real-time Scan-vs-BIM. Further, we describe the applications for such methods in construction and describes the challenges for their implementation. We conclude by implication of this paper on researchers working on augmented reality and construction robotics.@en
