Cultural relic reconstruction device based on ORB-SLAM

Abstract

ORB-SLAM, an advanced visual SLAM technology, has excellent positioning and mapping capabilities [1]. In the reconstruction of cultural relics, ORB-SLAM technology can achieve autonomous perception and modeling of the surrounding environment of cultural relics by fusing and analyzing the images of monocular depth cameras, thereby reconstructing the 3D model of cultural relics, providing new possibilities for the protection and inheritance of cultural relics. Point cloud images are a digital technology used for 3D modeling, which can save point data on object surfaces and their relationships as 3D point clouds [2]. In terms of cultural relic reconstruction, point cloud images can restore and reconstruct the shape, size, texture, and other features of cultural relics by processing the collected point data on the surface of cultural relics into a 3D model. The purpose of this device is to reconstruct cultural relics by generating point cloud images based on ORB-SLAM technology. Combined with the designed handheld pan tilt device, it can achieve multi-angle point cloud mapping of cultural relics scenes in complex terrain. This paper will introduce the handheld gimbal design of the device, the realization of point cloud mapping based on the ORB-SLAM3 algorithm [3], and the application of point cloud scenes. Through the research in this article, it is expected to provide a new and efficient method for cultural relic reconstruction in the field of cultural relic protection and make contributions to the protection and inheritance of cultural heritage.
