Disclosed is a method for detecting a parallel line by estimating more accurate vanishing point on a video image. According to the present invention, the method for detecting a parallel line by using estimation of a vanishing point includes the steps of: (a) extracting a plurality of lines, existing on the video image, by using a certain extraction method, and then calculating line strength for each pair of the extracted lines; (b) estimating candidate vanishing points by using probability distribution based on the line strength, and then selecting a final vanishing point from the candidate vanishing points; and (c) extracting the parallel line from the lines extracted in step (a) by using the selected final vanishing point. The vanishing point, which is more accurate, can be estimated because errors can be significantly reduced during the detection of noise or lines which occur in an existing method, and the parallel line, which is more accurate, can be detected by the method of the present invention.
