摘要： There are provided a method and apparatus capable of conveniently and rapidly inspecting a warpage of a rod. A rod to be inspected is rolled down an inspection bed and light shielded by the downwardly rolling rod is detected by a line sensor as a one-dimensional image signal. A positional fluctuation value of the downwardly rolling rod is obtained from a two-dimensional image signal obtained from the one-dimensional image signal. Based on the positional fluctuation value, the degree of the warpage of the rod is determined. The shielded light signal is detected in the vicinity of one end of the downwardly rolling rod to be inspected.
