Guide system having function of real-time voice response for the visually impaired and method thereof

摘要

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.

1. A guide system having a function of a real-time voice response for the visually impaired, comprising:
a visual sensing module sensing an image containing at least an object; 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 detect the object, segmenting and intercepting the detected object from the image so as to create at least a segmented image, tracking the segmented image, performing an object detection process to the segmented image so as to extract an object characteristic of the segmented image, and performing an object recognition process to the object characteristic so as to find correspondence in the training samples stored in the memory and create a recognition signal; a system processing module performing a human machine interface, receiving the recognition signal and finding correspondence in the multiple pieces of audio response information stored in the memory based on the recognition signal so as to create an audio signal; and an audio module outputting a speech voice hearable by a user based on the audio signal, wherein the guide system responds to road conditions in real time using the image processing module and the system processing module performing image processing and voice responses, respectively.
