Constructing Locally Dense Point Clouds Using OpenSfM and ORB-SLAM2
This addresses a specific registration challenge for 3D reconstruction applications, but it is incremental as it builds on existing methods with a tag-based approach.
The paper tackles the problem of registering point clouds from ORB-SLAM2 and OpenSfM by using tags with unique textures to localize positions and compute a transformation matrix, enabling alignment of the two point clouds.
This paper aims at finding a method to register two different point clouds constructed by ORB-SLAM2 and OpenSfM. To do this, we post some tags with unique textures in the scene and take videos and photos of that area. Then we take short videos of only the tags to extract their features. By matching the ORB feature of the tags with their corresponding features in the scene, it is then possible to localize the position of these tags both in point clouds constructed by ORB-SLAM2 and OpenSfM. Thus, the best transformation matrix between two point clouds can be calculated, and the two point clouds can be aligned.
