Blind guiding cap which is used for being worn by human body and is equipped with full-depth of field sensing function

Abstract

The invention discloses a blind guiding cap which is used for being worn by a human body and is equipped with a full-depth of field sensing function, relates to the blind guiding cap and belongs to the field of photoelectric blind guiding. The blind guiding cap comprises a 3D photographing unit, a signal processing unit and a contact array unit for sensing the human body. The 3D photographing unit comprises a near-infrared light source for carrying out near-infrared active illumination, and a left near-infrared photographing photoelectric sensor and a right near-infrared photographing photoelectric sensor which are used for carrying out double-camera photographing. The signal processing unit comprises a preprocessing unit, a depth extraction unit and a quantitative output unit. A miniature electromagnet controlled contact firing pin structure is employed by a single contact structure in the contact array unit. According to the blind guiding cap, through adoption of a stimulation method by four-dimensional comprehensive information such as a scenery orientation, a size, color difference and distance, the blind is helped to realize a target of ''seeing'' the light through a memory based learning process; and the inconvenient life problems of the blind due to the electric stimulation conductive mode of a traditional sensing contact tool through a lingual surface and an armpit can be solved.

Description

technical field [0001] The invention belongs to the field of photoelectric blind-guiding technology, in particular to a blind-guide cap that can be worn by a human body and has the function of infrared panoramic depth perception. Background technique [0002] Total blindness and visual impairment are one of the serious social and public health problems in the world. In 2014, the total number of visually impaired people in the world was close to 200 million, of which the number of blind people in my country has reached more than 6 million, and a new case is still being added every minute. increase the amount. These vision-impaired patients are unable to move freely in daily life and need nursing care. On the one hand, it brings a heavy burden to the family and the society. On the other hand, it also has a serious impact on the mental health of the patients themselves, and is prone to low self-esteem. , self-loathing and other emotions. [0003] At present, the existing blind...

Problems solved by technology

[0004] The present invention discloses a blind guide cap with infrared panoramic depth perception function worn by the human body. The technical problem to be solved is to overcome the defects that the existing blind guide equipment cannot provide information such as the size, orientation and distance of the scene at the same time, so that blind people Through training and learning, the distance, position, and outline of the scene objects can be outlined in the brain, so as to realize the blind guide
