(a) Schematic of test set-up for a simple supported beam captured by four cameras (C1–C4 as seen in (b)); the fields of views (FOV1–FOV4) of the four cameras are overlapped and symmetric with the centerline; (b) the four cameras (C1–C4) in the real set-up; (c) the captured scene before loading by the camera C1 and the region of interest.
