Intelligent mobile phone blind-guiding device and blind-guiding method

Abstract

The invention discloses an intelligent mobile phone blind-guiding device, comprising a mobile phone camera module, an embedded mobile phone processor, a software module, a mobile phone wireless signal emitting and receiving module, an input and output interactive module and a back ground server, wherein the mobile phone camera module comprises a mobile phone pick-up lens and an image sensor; the embedded mobile phone processor and the software module comprise an embedded processor and an embedded operating system of a mobile phone as well as application software running on the embedded operating system; and the application software is blind-guiding software. Feature analysis is carried out on collected images through a machine vision technology, and the features of field images are matched with obstacle parameters in a background database by using an artificial intelligence technology, thereby achieving recognition and position interpretation of barriers and using voice and vibratory modes to prompt a blind person to move. The blind-guiding device of the invention is in common use and is low in cost, and has functional expansibility and upgrading capabilities.

Description

technical field [0001] The invention relates to a blind guide technology, in particular to a blind guide technology and a blind guide method controlled by a mobile phone embedded system. Background technique [0002] As we all know, mobile phones have become indispensable electronic products in people's lives. With the increasing processing power of embedded processors, the combination of machine vision technology, sensor technology, wireless transmission technology and artificial intelligence technology on the hardware platform of mobile phones has enabled smart phones to develop many advanced functions and applications for better Meet the needs of people's lives. [0003] Using new technologies to develop disability-assisting products for the disabled is an industry with potential development potential. According to statistics in 2005, China is the country with the largest number of blind people in the world, with about 5 million blind people, accounting for 18% of the t...

AI Technical Summary

Problems solved by technology

However, ordinary mobile phones generally do not have infrared, laser and other distance sensors, nor do they have temperature sensors.

Therefore, in order to realize guide blindness, new equipment needs to be installed on existing mobile phones, and the cost increases

Moreover, the invention patent also applies to the local database, and the storage capacity of the mobile phone is quite limited, which is not conducive to the accumulative accumulation of "obstacle" data, so the development potential of the program's environmental adaptability is limited

[0011] Similar foreign products are developing in the direction of service robots, so the use of complex mechanical structures and control software increases the cost of robots and makes it difficult to promote products
