An Efficient Urban Building Height Rover using Ultrasonic Sensor

A significant proportion of mobile surveying systems in the market are not economically viable due to their inconvenience in operation such as large size, complex data processing requirements and limited accessibility to areas without vehicle access. This paper proposes a model to deploy a rover-based system to address the challenges to measure the height of the building and object in urban environments using a low-cost, easy-to-assemble system comprising ultrasonic sensors, stepper motors and a laser system. Here, it integrates calibration mechanisms to be highly accurate, and the rover's modular architecture promotes robustness and easy replication for multiple scenarios. This advances the measurement of building heights in urban settings by enhancing users’ control of the process, and in delivering results that reflect local requirements.
