Summary:In the Japanese construction industry, An UAV has begun to be used for outdoor works. On the other hand, most of building equipment works is indoor work, often working in touch with the surrounding environment near the ceiling. Air volume measurement is an example of building equipment works near the ceiling. Conventionally, a worker gets on a temporary scaffold to approach the ceiling at the high position and measures the air volume just under the diffuser installed on the ceiling with using the handy type anemometer. This conventional work has low productivity and high cost for safety management. Furthermore, this tendency is remarkable in rooms with high ceilings such as entrance halls and factories. We propose a new measurement method using the UAV with air volume measuring device, and develop and evaluate the system. The visual feedback control system for self-localization is also developed because the GPS cannot be used indoors. In addition, a high ceiling room with the diffuser is constructed as a mock-up for experiment. We analysed the positioning errors of the UAV when hovering and when approaching and touching the diffuser. Also, we evaluated the touch performance of the UAV to the ceiling by measuring the air volume. As a result, it was found that the UAV can ensure the performance necessary for air volume measurement in this experiment.
