Disclosed is an object detection method and a system thereof. The object detection method for detecting an object, the method comprising the steps of: extracting line segments from an image in which a detection target is displayed, by an object detection system, generating merged line segments on the basis of directionality of each of the extracted line segments, by the object detection system, specifying candidate outer lines corresponding to outer lines of the object on the basis of a line segment set including the generated merged line segments, by the object detection system; and specifying the candidate outer lines as the outer lines of the object on the basis of whether or not the specified candidate outer lines correspond to appearance attributes of the object, by the object detection system.

System and method for object detection

An object recognition method performed by an object recognition system includes: setting a first binarization area in a portion of a binarization target area of an image, and a first coefficient calculation area including the first binarization area and having an area wider than the first binarization area by a predetermined ratio; determining a first binarization coefficient on the basis of pixel values included in the first coefficient calculation area; performing binarization on the first binarization area through the determined first binarization coefficient; setting a second binarization area in a portion other than the first binarization area, and a second coefficient calculation area including the second binarization area and having an area wider than the second binarization area; determining a second binarization coefficient on the basis of pixel values included in the second coefficient calculation area; and performing binarization on the second binarization area through the determined second binarization coefficient.
