Phone, it is also possible to for broadcast listening or music etc..
Preferably, the second mirror foot 106 is provided with GPS module 9, for positioning general location and the offer of blind person 10
Voice Navigation services, and blind person 10 can the most clearly know oneself residing general location by described GPS module 9, such as
Near so-and-so street, so-and-so landmark etc., effectively prevent blind person 10 and get lost the generation of phenomenon.
Navigation spectacles 100 of the present invention mainly utilizes the infrared reflecting mark arranged in the surrounding that blind person 10 walks
7 navigate, and described infrared reflecting mark 7 is for be had mark action by what infrared reflecting material (such as metal powder etc.) was made
Figure, for reflecting the infrared light that described infrared light supply 202 sends.When infrared light supply 202 is irradiated to the infrared reflecting of surrounding
Reflex can occur when identifying 7, and now infrared camera 203 will capture infrared external reflection light and generate infrared image, figure
As infrared image is identified processing and draw that recognition result is (representated by i.e. current infrared reflecting mark 7 by processing unit 201
Graphical meanings), final voice module 3 sends different phonetic prompting according to different image recognition result, thus has ensured blind person
Walking safety.
Present invention also offers a kind of navigation system 200, described navigation system 200 includes the navigation spectacles of the invention described above
100 and infrared reflecting mark 7, as in figure 2 it is shown, described infrared reflecting mark 7 is divided on the ground mark 11 and land marking 12.Blind person
10 wear described navigation spectacles 100 after can know on the ground mark 11 or the information of land marking 12 by voice, thus real
Existing navigation function.Described ground mark 11 and land marking 12 be Pasting or can the flaky texture of hot melt, such that it is able to directly
Connect and paste or be thermally melted in guideboard, billboard, metope, blind road floor tile or the surface of special Sign Board.
Fig. 3 to Fig. 5 shows an embodiment of navigation system 200 of the present invention, the most described infrared reflecting
Mark 7 (i.e. land markings 11) are that one or more infrared reflecting point 15 forms, and described infrared reflecting point 15 constitutes and has
The figure of mark action.Blind road floor tile is divided into traveling blind road floor tile 13 and prompting blind road floor tile 14, wherein has bar shaped to guide brick
For traveling blind road floor tile 13 (such as Fig. 3 (a)), it is used for guiding blind person or blind person is relieved moves ahead；Prompting brick with round dot is prompting
Blind road floor tile 14 (such as Fig. 3 (b) to Fig. 3 (f)), for pointing out the spatial environments in blind person or blind person front to change, is arranged
Starting point, terminal and corner in traveling blind road floor tile 13.
As shown in Fig. 3 (a), the centre position stickup of each strip bulge, hot melt or embedded on traveling blind road floor tile 13
Having infrared reflecting point 15, it is possible to one-body molded with traveling blind road floor tile 13, all 4 infrared reflecting points 15 connect and manifest straight line i.e.
Define the figure (i.e. infrared reflecting mark 7) with mark action, for identifying the width of traveling blind road floor tile 13, to prevent
Sidewalk for visually impaired people is deviateed when blind person 10 walks.
Similarly, as shown in Fig. 3 (b) to Fig. 3 (f), glue selectively on the circular protrusions surface of prompting blind road floor tile 14
Patch, hot melt or be embedded with infrared reflecting point 15, it is possible to the most one-body molded with prompting blind road floor tile 14；Wherein in Fig. 3 (b)
8 infrared reflecting points 15 present after connecting rotate 45 degree square, Fig. 3 (c) presents after 5 infrared reflecting points 15 connections to
In oblique line that right bank is 45 degree, Fig. 3 (d) 5 infrared reflecting points 15 present after connecting be tilted to the left 45 degree oblique line, in Fig. 3 (e)
8 infrared reflecting points 15 present 9 infrared reflecting points 15 in " T " font, Fig. 3 (f) and present " ten " font after connecting after connecting, point
Not Yong Yu expression will enter bend maybe will enter straight way, turn round to the right, turn round to the left, the junction of three roads and crossroad.
Can obtain when the infrared camera 203 of navigation spectacles 100 of the present invention is towards front lower place shooting blind road floor tile
Different mark shapes, and analyze specifically which kind of mark by graphics processing unit 201, further analysis result is reached
Voice module 3, thus send voice prompt blind 10 by earphone 303 and notice turning in sidewalk for visually impaired people.By the navigation system of the present invention
200 can be accurately identified blind person 10 is expert at and passes by the information of sidewalk for visually impaired people, Cheng Qian side and whether front has barrier, simultaneously
In conjunction with described GPS module 9, blind person 10 is carried out location and can be effectively improved range of activity and the walking safety of blind person 10.
Owing to the construction of sidewalk for visually impaired people, city is lack of standardization or sidewalk for visually impaired people is by reasons such as other objects occupy, blind person 10 is caused to walk in sidewalk for visually impaired people
Time there is certain security risk, can effectively solve this problem, infrared camera by navigation system 200 of the present invention
203 obtain infrared identification point 15 image on sidewalk for visually impaired people, analyze through graphics processing unit 201 and do not include in image or the most entirely include red
Outer identification point 15, then point out sidewalk for visually impaired people, blind person 10 front to there is barrier by voice module 3, thus effective guarantee blind person 10 be blind
Walking safety on road.
Fig. 5 shows that blind person 10 uses the application scenarios figure of navigation system of the present invention, has worn navigation spectacles 100 of the present invention
Blind person 10 walk on sidewalk for visually impaired people, adjust the shooting angle of described infrared camera 203 so as towards front lower place shoot blind road floor tile
On infrared reflecting point 15.As it is shown in figure 5, blind person 10 will hear successively first corner be from straight way enter curved
Road, turn round to the right, enter the voice message such as straight way from bend；Will hear successively second corner is to enter from straight way
The junction of three roads, turn round or turn round to the right, enter the voice message such as straight way from bend, when blind person 10 deviates in the process of walking to the left
During sidewalk for visually impaired people, voice module 3 can send prompting and lead back to walk on sidewalk for visually impaired people.
Navigation spectacles of the present invention and navigation system can effectively help blind person 10 walk safely have infrared instead
In the city space of light mark or on sidewalk for visually impaired people, solve the difficult problem that sidewalk for visually impaired people, city utilization rate is low the most efficiently, need only be existing
Increasing infrared reflecting on sidewalk for visually impaired people to identify, the range of activity that improve blind person has simple in construction, with low cost, exploitativeness
By force, navigate the advantage such as accurate, applied widely.
Described accompanying drawing is only and schematically and not in scale draws.Although the present invention being entered already in connection with preferred embodiment
Go description, it is to be understood that protection scope of the present invention is not limited to embodiment as described herein.
In conjunction with explanation and the practice of the present invention disclosed here, other embodiments of the present invention are for those skilled in the art
All it is easy to expect and understand.Illustrating and embodiment is to be considered only as exemplary, true scope and the purport of the present invention are equal
It is defined in the claims.
