摘要
Disclosed are an apparatus and a method for detecting a bar-type sign in a traffic sign recognition system. The method may include a traffic sign detection step of detecting a traffic sign from image information including the traffic sign; a recognition region setting step of setting a recognition region on the traffic sign detected through the traffic sign detection step; a principal component analysis (PCA) operation processing step of applying a PCA algorithm to all pixels in the recognition region set through the recognition region setting step, and determining an eigenvector; and a sign determination step of determining an angle “α” of the eigenvector, comparing a deviation “d” of the determined angle with a threshold value “Pt”, and determining whether to correspond to a bar-type sign.
