BSD APPARATUS AND METHOD FOR CALIBRATING BLIND SPOT DETECTION

摘要

An object of the present invention is to provide an apparatus for calibrating blind spot detection (BSD) capable of using internal parameters of an image recognition algorithm according to a location change of a camera without tuning, and a method therefor. To this end, the apparatus comprises: a panel recognition unit configured to detect markers from a camera image in which a calibration panel including the plurality of markers and patterns around the markers is captured so as to extract coordinates of the markers; an image generation unit configured to transform a viewpoint of the camera image based on the coordinates of the markers to generate an aerial view image; a pattern correction unit configured to extract the patterns around the markers from the aerial view image, compare the extracted patterns with normal patterns of a normal aerial view image, and adjust the coordinates of the markers to minimize a difference between the extracted patterns and the normal patterns; a BSD recognition unit configured to extract a rotation angle for image transformation to be used in BSD recognition from the camera image based on the adjusted coordinates of the markers and a boundary region to be cut from the aerial view image to determine a view image region; and a storage unit configured to store determined calibration data between original images corresponding to pixel locations of a view image to be generated by applying the determined rotation angle and boundary region. Therefore, the present invention can use internal parameters of an image recognition algorithm according to a location change of a camera without tuning, thereby providing performance that is the same as or similar to that of recognition performance that is developed and well-tuned in a conventional case.
