CROSSWALK GUIDE APPARATUS AND METHOD FOR PEDESTRIANS OF THE VISUALLY IMPAIRED

摘要

The present invention relates to a guide apparatus and method for walking in a crosswalk for a visually impaired person, and an apparatus according to an embodiment of the present invention includes an image acquisition unit for collecting a front image transmitted from a terminal worn by a blind person, a front image A crosswalk detector that sets a plurality of first ROIs for , and estimates the first ROIs corresponding to the crosswalk through at least one of feature-based analysis or machine learning for the first ROIs; One central region is set as a second region of interest, and candidate regions including a gait signal among the second regions of interest are estimated through at least one of feature-based analysis or machine learning of the second region of interest, and A gait signal detector that determines the state of the included gait signal, generates projection data based on the horizontal direction based on the first regions of interest corresponding to the crosswalk, and analyzes the change in inclination of pixel values constituting the projection data. It may include an information analysis unit for generating walking guide information output to the user interface of the terminal based on the output data of the traveling direction determination unit and the crosswalk detection unit, the walking signal detection unit and the traveling direction determination unit for estimating the traveling direction of the visually impaired. .
