Three-dimensional map construction method for indoor mobile robots based on visual SLAM technology

With the development of machine vision technology and the update of sensors, the rapid development of visual SLAM technology has been promoted. Indoor robots require accurate maps for path planning and navigation, and vision-based SLAM technology has rich semantic information and can provide robots with more accurate maps. Compared with sensors such as lidar, it has higher indoor applicability. Therefore, visual SLAM technology is widely used in the scenario of three-dimensional map construction for indoor mobile robots. This article introduces the development of SLAM technology and mainstream technologies in detail, introduces traditional SLAM technology and visual SLAM technology, and introduces some current research status. In this particle, the mainstream technology classification of visual SLAM technology is introduced, previous solutions are discussed, and the future research and development direction of visual SLAM technology is provided based on the advantages, disadvantages, and shortcomings of previous researchers, and based on this conclude this article.
