1. An object measuring system for measuring the number of moving objects passing a boundary line, comprising:

  • an extractor for extracting motion vectors at a plurality of times in each of a plurality of positions on said boundary line on the basis of a plurality of images;

    an integrator for obtaining at least one integral value derived by integrating perpendicular components perpendicular to said boundary line of said motion vectors, said at least one integral value being derived by integrating the perpendicular components of one of positive and negative signs; and

    a calculator for calculating the number of moving objects passing said boundary line on the basis of said at least one integral value.
