Abstract
The present invention is directed to a guide system having a function of a real-time voice response for the visually impaired and a method thereof. The guide system responds road conditions in real time using two processing modules performing image processing and voice responses, respectively. The guide system includes an visual sensing module sensing an image, a memory storing multiple training samples and multiple pieces of audio response information, an image processing module performing an image detection process to the image so as to create at least a segmented image, performing an object detection process to the segmented image, and performing an object recognition process so as to create a recognition signal, a system processing module creating an audio signal based on the recognition signal such that a speech voice is hearable by a user.
