The aim of this study is to help individuals easily reach their destinations independently whenever they are situated in an unfamiliar environment. After performing pre-processing optimization, a map constructed by simultaneous localization and mapping (SLAM) is inputted to a route planning algorithm to find the most suitable path. The proposed method utilizes a stereo camera sensor to take images of the environment, after which it conducts 2D/3D mapping through the SLAM framework before converting the constructed map into images. Then, obstacles are identified using an image segmentation method, and pseudo-obstacles are filtered out through optimization. Finally, route planning is conducted using the D*Lite algorithm. Experimental results revealed that most of the pseudo-obstacles can be filtered out through image optimization, thereby increasing the accuracy of the 2D map.
