To improve the estimation accuracy of a fresh concrete amount inside a mixer drum.SOLUTION: Fresh concrete amount estimation devices 100, 200 include cameras 20, image processing parts 31 that extract an exposed region 61 from images 60 captured by the cameras 20, and estimation parts 32 that estimate the amount of fresh concrete inside a mixer drum 2 based on the exposed region 61 extracted by the image processing parts 31. The image processing parts 31 extract the regions inside the projected circle 8c which is the projection of a conical cover member 8 provided on the bottom of the mixer drum 2 projected in the imaging direction of the camera 20 as the exposed region 61 from the images 60.SELECTED DRAWING: Figure 5

    【課題】ミキサドラム内の生コンクリート量の推定精度を向上させる。【解決手段】生コンクリート量推定装置100,200は、カメラ20と、カメラ20が撮像した撮像画像60から露出領域61を抽出する画像処理部31と、画像処理部31が抽出した露出領域61に基づきミキサドラム2内の生コン量を推定する推定部32と、を備える。画像処理部31は、ミキサドラム2の底部に設けられる円錐状のカバー部材8をカメラ20の撮像方向に投影した投影円8c内の領域を、撮像画像60から露出領域61として抽出する。【選択図】図5
