A method for detecting a bridge connecting failure to detect a bridge shorting terminals of a component includes acquiring a 2D image and height-based information through lights irradiated on a board, acquiring rotation information of the component using at least one of the 2D image and the height-based information, establishing an inspection region for detection of the bridge connecting failure using the rotation information, extracting a first bridge region within the inspection region using the 2D image, extracting a second bridge region within the inspection region using the height-based information, and judging whether the bridge connecting failure of the component occurs by using at least one of the first and second bridge regions. Thus, the method may inspect more precisely the bridge connecting failure through the first bridge region extracted from the 2D image and the second bridge region extracted from the height-based information.
