In this paper, we propose a novel iterative closest point (ICP)-based simultaneous localization and mapping (SLAM) approach that can build robust map infor-mation even in indoor environments where humans coexist. Several SLAM methods that have been studied so far assume a stationary environment. But there are challenges in operating in a dynamic environment with moving objects such as humans. Specifically, when a mobile robot constructs a map in an environ-ment where humans coexist nearby, humans cause false matching in alignment sensor data. Furthermore, human occlusion also makes it difficult to construct a map with high accuracy. Therefore, we propose a human removal process that utilizes You Look Only Once (YOLO) to detect humans in image data. In this paper, by using this process with ICP-SLAM, we aim to improve the accuracy of map construction in an environment where humans coexist nearby. In our exper-iments, we verified the accuracy of map construction in comparison with conven-tional methods. This experiment is conducted in an indoor corridor where hu-mans coexist nearby. Although we used ICP-SLAM for verification this time, the human removal process can be adapted to other SLAMS.
