Review of Research on Visual Simultaneous Localization and Mapping Perception Technology for Dark and Weak Environments

Visual SLAM technology uses visual cameras as the primary sensors to create environmental maps while performing self localization. SLAM technology can achieve autonomous positioning, path planning, obstacle avoidance, and other functions through the creation of maps. SLAM technology has shown good performance in indoor positioning, but unknown indoor environments often have problems such as weak lighting. This article provides an overall introduction to the process of visual SLAM systems and the technology of perceiving dark environments, and analyzes future development trends.
