Simultaneous localization and mapping technology is commonly used within mobile devices and household appliances—it allows our vacuum robot to navigate the living room and enables us to view augmented reality content on our smartphones. By examining simultaneous localization and mapping–based devices and contrasting them against more traditional forms of cartographic practices, we argue that simultaneous localization and mapping technology not only opens up interior spaces for geographic examination but also calls into question the categorical difference between inside and outside itself. As with simultaneous localization and mapping, the mathematical construction of the surrounding space happens in the moment of its detection, simultaneous localization and mapping exhibits a moment of radical situativeness that is freed from the constraints of a stabilized, external database. We propose that this moment of situativeness, which is also inscribed into the resulting highly mobile and fluid visualizations, is the defining feature of a new kind of geomedia that simultaneously establish a vertical and a horizontal geography.

AbstractIn recent years, simultaneous localization and mapping in dynamic environments (dynamic SLAM) has attracted significant attention from both academia and industry. Some pioneering work on this technique has expanded the potential of robotic applications. Compared to standard SLAM under the static world assumption, dynamic SLAM divides features into static and dynamic categories and leverages each type of feature properly. Therefore, dynamic SLAM can provide more robust localization for intelligent robots that operate in complex dynamic environments. Additionally, to meet the demands of some high-level tasks, dynamic SLAM can be integrated with multiple object tracking. This article presents a survey on dynamic SLAM from the perspective of feature choices. A discussion of the advantages and disadvantages of different visual features is provided in this article.

Visual simultaneous localization and mapping (VSLAM) is an essential technique used in areas such as robotics and augmented reality for pose estimation and 3D mapping. Research on VSLAM using both monocular and stereo cameras has grown significantly over the last two decades. There is, therefore, a need for emphasis on a comprehensive review of the evolving architecture of such algorithms in the literature. Although VSLAM algorithm pipelines share similar mathematical backbones, their implementations are individualized and the ad hoc nature of the interfacing between different modules of VSLAM pipelines complicates code reuseability and maintenance. This paper presents a software model for core components of VSLAM implementations and interfaces that govern data flow between them while also attempting to preserve the elements that offer performance improvements over the evolution of VSLAM architectures. The framework presented in this paper employs principles from model-driven engineering (MDE), which are used extensively in the development of large and complicated software systems. The presented VSLAM framework will assist researchers in improving the performance of individual modules of VSLAM while not having to spend time on system integration of those modules into VSLAM pipelines.
