  • Marker used for measuring displacement of moving object and method therefor
    Patent number: 6731392
    Abstract: The present invention discloses a displacement measurement marker capable of measuring displacement of an object moving on a plane by using a line scan camera, and a displacement measurement method using the same. The displacement measurement marker according to the present invention comprises a plurality of repeatedly arranged figures having the same size and shape. Each of the figures is measurable by means of the line scan camera and is asymmetric with respect to a direction of a scan line of the line scan camera. Preferably, each of the figures is a right-angled triangle of which base is a horizontal line. According to the present invention, there are advantages in that a two-dimensional planar motion of the object can be measured from one-dimensional linear image data, and the motion of the object which moves at a high speed or on which an impact is exerted can be accurately measured.
