Abstract:
A ready-mixed concrete amount estimation device (100, 200) is provided with: a camera (20); an image processing unit (31) that extracts an exposure region (61) from a captured image (60) captured using the camera (20); and an estimation unit (32) that estimates a ready-mixed concrete amount inside a mixer drum (2) on the basis of the exposure region (61) extracted by the image processing unit (31). The image processing unit (31) extracts, from the captured image (60) and as the exposure region (61), a region inside a projected circle (8c) obtained by projecting a conical cover member (8) provided at a bottom part of the mixer drum (2) in an image capturing direction of the camera (20).
