Indoor mapping plays a crucial role in various fields such as robotics and building infrastructure management. Accurate distance measurement and mapping are essential for effective indoor mapping. This study reviews existing literature on ultrasonic and LiDAR (Light Detection And Ranging) sensors in indoor mapping applications, highlighting their capabilities and limitations. It conducts a comprehensive comparative analysis of the HC-SR04 and TF-LC02 sensors in terms of accuracy, range, mapping capabilities, and suitability for indoor mapping tasks and addresses the corresponding challenges. The findings of this work will provide valuable guidance for researchers in selecting the most suitable sensor technology for indoor mapping, leading to improved localization accuracy and mapping resolution.
