Abstract:
1. An object detecting method performed by a computer executing instructions of a program embodied in a non-transitory computer-readable medium, said method performed by the computer comprising: dividing an area of a standard pattern into two or more areas radially from an area dividing central point; selecting, in each of the divided areas of the standard pattern, a standard pattern pixel position at the maximum distance from the area dividing central point as a standard pattern representative point; dividing an area of a determined pattern into two or more areas under the same condition as in the selecting of the standard pattern representative point and with reference to the area dividing central point; selecting, in each of the divided areas of the determined pattern, a determined pattern pixel position at the maximum distance from the area dividing central point as a determined pattern representative point; determining a positional difference between the coordinates of the standard pattern representative points and the coordinates of the determined pattern representative points in the corresponding divided areas; and determining the determined pattern as a target object when the positional differences in all of the divided areas are within a predetermined range, wherein each of the selecting of the standard pattern representative point and the selecting of the determined pattern representative point includes setting a center or a geometric center of the corresponding pattern as the area dividing central point.
