Abstract

The invention discloses an intelligent visual impairment auxiliary system based on a distributed multi-source heterogeneous sensing technology. The intelligent visual impairment auxiliary system is characterized by distributed settings, wherein a head-mounted device, a waistcoat, a waistband, a wristband, a walking stick and a blind guiding robot dog in communication connection are integrated withan infrared ranging sensor, far infrared imaging technology, a GPS, an ultrasonic ranging sensor, a depth camera, an RGB camera and other sensing modules. Collaborative data acquisition and data processing and analysis are made between multi-source heterogeneous sensors to meet the needs of different applications such as indoor and outdoor positioning and obstacle avoidance for visually impairedpeople. Compared with the prior art, the system has the functions of indoor and outdoor positioning, interactive reading and the like, can accurately obtain effective information in a complex application scene and accurately and comprehensively transmit the effective information so as to meet visual impairment assistance in different environments and help visually impaired people to effectively avoid obstacles, and is simple in structure, convenient to use and high in reliability.

Description

technical field [0001] The invention relates to the technical fields of multiple positioning modes and text image recognition processing, and specifically relates to an intelligent visually impaired assistance system based on distributed multi-source heterogeneous sensing technology. Background technique [0002] Visually impaired people (including partially visually impaired people and totally blind people) have caused a lot of inconvenience in life due to lack of vision. Therefore, people have been working hard to study auxiliary devices to improve the quality of life of visually impaired people. Designing an intelligent visually impaired assistance system can provide visually impaired This has become a research hotspot today, and there are many achievements and applications in this field of assisting the visually impaired. [0003] Application number: 2013203817903 discloses a cane for the visually impaired. The cane is a traditional assistive tool for the visually impair...
