REMOVAL/ABANDONMENT DETERMINATION DEVICE AND REMOVAL/ABANDONMENT DETERMINATION METHOD

摘要

A removal/abandonment determination device includes: a sampling point setting unit configured to set sampling points on a boundary line of an object; a luminance determination unit configured to determine whether a ratio of an area having the same luminance in a peripheral region of each of the sampling points is a first certain value or more; and a removal/abandonment determination unit. The removal/abandonment determination unit determines that the object is removed when the sampling points of which the ratio is determined as being the first certain value or more are a second certain value or more, and determines that the object is abandoned when the sampling points of which the ratio is determined as being the first certain value or more are less than the second certain value.
