    • An object type determination apparatus, an object type determination method, a vehicle, and a program for determining an object type, capable of accurately determining the type of the object by appropriately determining periodicity in movement of the object from images, are provided. The object type determination apparatus includes an object area extracting means (11) for extracting an area of an object from an image picked up by an image pick-up means (2R, 2L), an object end point extracting means (12) for extracting an end point of an image portion of the object from the extracted object area, an object periodicity determination means (13) for calculating time series data of a feature value representing a size of the object using the end point of the image portion of the object extracted by the object end point extracting means (12) from the area of the object extracted by the object area extracting means (11) for respective ones of time series images picked up by the image pick-up means (2R, 2L) to determine whether the feature value changes with prescribed periodicity, and a living body determination means (14) for determining the object having the feature value determined to change with periodicity as a living body.
    • 提供了一种对象类型确定装置,对象类型确定方法,车辆和用于确定对象类型的程序,能够通过从图像适当地确定对象的移动周期来精确地确定对象的类型。 对象类型确定装置包括:对象区域提取装置,用于从由图像拾取装置(2R,2L)拾取的图像中提取对象的区域;对象终点提取装置(12),用于提取 来自提取的对象区域的对象的图像部分的终点;对象周期性确定装置(13),用于使用对象的图像部分的终点来计算表示对象的大小的特征值的时间序列数据 由对象终点提取装置(12)从由对象区域提取装置(11)提取的对象区域针对由图像拾取装置(2R,2L)拾取的各个时间序列图像提取出来,以确定 所述特征值是否以规定的周期性变化,以及生物体确定装置(14),用于确定被确定为周期性变化的特征值的物体作为活体。
