Shopping guide method and apparatus for blind in supermarket based on bar code identification

Abstract

The invention relates to a blindman supermarket shopping guide method based on a bar code identification and a device thereof which belong to the technical field of ancillary equipment of for the disabled. The device comprises the bar code identification, a supermarket information read-in unit, a bar code identification unit and a voice synthesis output unit. The specific proposal is characterized by arranging three types of bar codes which are respectively big size, medium size and small size in a supermarket, acquiring images in the vision range of a user by the supermarket information read-in unit, detecting and decoding the bar codes in the vision range of the user, using code information and position information corresponding to the bar codes to encode stereo, and outputting the stereo to the blindman by an earphone, thus helping the blindman know commodity regions, goods arrangement, and the name, trademark and price of a single item in the supermarket. The method and the device are mainly used for assisting the blind in shopping in the supermarket independently.

Description

technical field [0001] The present invention relates to a method and device for guiding the blind in the technical field of detection, in particular to a method and device for guiding blind people in supermarkets based on barcode identification. Background technique [0002] Nearly 80% of the external information obtained by humans depends on vision, and the other 20% comes from hearing and touch. However, for blind people, due to the loss of vision, an important channel for information acquisition, their life and work are greatly restricted. In order to improve the quality of life of blind people and reduce the inconvenience caused by blindness, scientists consider using sensory substitution methods to transmit some important information to blind people through auditory or tactile channels. [0003] Blind sticks and guide dogs have improved the quality of life of blind people to a certain extent, but they can only provide basic walking guidance for blind people, and it is d...

Problems solved by technology

However, this technology is not targeted for object detection, the algorithm is complex and not real-time, and there is no way to provide blind people with information such as commodity division and cargo type that can help blind people find objects quickly.

The most important thing is that the environment of supermarket shelves is complex, there are many items and different types, and the accuracy and reliability of object recognition algorithms are not guaranteed.
