Plane Registration Leveraged by Global Constraints for Context-Aware AEC Applications
نویسندگان
چکیده
In this article, we propose a new registration algorithm and computing framework, the KEG tracker, for estimating a camera’s position and orientation for a general class of mobile context-aware applications in Architecture, Engineering, and Construction (AEC). By studying two classic natural marker-based registration algorithms, Homography-from-detection and Homography-from-tracking, and by overcoming their specific limitations of jitter and drift, our method applies two global constraints (geometric and appearance) to prevent tracking errors from propagating between consecutive frames. The proposed method is able to achieve an increase in both stability and accuracy, while being fast enough for real-time applications. Experiments on both synthesized and real-world test cases demonstrate that our method is superior to existing state-of-the-art registration algorithms. The article also explores several AEC applications of our method in context-aware computing and desktop-augmented reality.

متن کاملPlane-based Coarse Registration of 3d Point Clouds with 4d Models
The accurate registration of 3D point clouds with project 3D/4D models is becoming more and more important with the development of BIM and 3D laser scanning, for which the registration in a common coordinate system is critical to project control. While robust solutions for scan-model fine registration already exist, they rely on a fairly accurate prior coarse registration. This paper first show...
