To provide a chimney internal inspection method capable of inspecting a state of an inner surface of a chimney with more high accuracy.SOLUTION: A chimney internal inspection method comprises: flying a flying object equipped with an optical sensor inside the chimney; measuring a distance to the inner peripheral surface of a chimney with the optical sensor while flying the flying object in a predetermined measurement target range of the inner peripheral surface; and based on the measurement result, generating a distribution map showing unevenness distribution in the measurement target range of the inner peripheral surface.SELECTED DRAWING: Figure 6
【課題】煙突の筒身内面の状態をより高精度に検出可能な煙突内部点検方法を提供する。【解決手段】煙突内部点検方法は、光センサを搭載する飛行体を煙突の内部で飛行させ、飛行体を飛行させつつ光センサにより煙突の内周面までの距離を内周面の所定の測定対象範囲について測定し、測定結果に基づいて、内周面の測定対象範囲における凹凸の分布を示す分布図を生成する。【選択図】図6
