Abstract

The present invention relates to a cane with a camera sensor and a voice transmission microphone, in which a camera sensor for front object recognition can determine what objects are 20 meters ahead and what the terrain is like, thereby solving problems that a change in a ground surface can be grasped, but what exists if going deeper and what is several meters ahead cannot be identified. The present invention provides a cane for the visually impaired comprising: a camera sensor for front object recognition installed inside the cane to determine what objects are 20 meters ahead and what the terrain is like; and a voice transmission speaker, that is a Bluetooth speaker installed inside the cane, so as to instantly transmit information on an object recognized by the cane to the visually impaired so that the determined object and terrain can be explained and noticed for enabling the visually impaired to understand the object and the terrain. Therefore, the present invention provides the camera sensor for front object recognition that can determine what objects are 20 meters ahead and what the terrain is like, thereby solving problems that a change in a ground surface can be felt, but what exists if going deeper and what is several meters ahead cannot be identified.
