Description
Technical field
Field of the present invention is related to a kind of blind person's product more particularly to a kind of blind person vibration and contacts matrix perception photo is set
It is standby.
Background technique
Blind person has braille when carrying out reading text, but in terms of knowing figure, because scheming without relevant art knowing
When, because general photograph does not have profile information outstanding, thus when blind person is known with feel again, is inconvenient, cannot know feel
Information is communicated to blind person well.
Summary of the invention
The object of the present invention is to provide one kind by converting sketch profile diagram for photo, then passes through the shake on touch tablet
It moves device or contacts matrix and photo profile information is communicated to blind person.
The technical scheme is that a kind of blind person's vibration and contacts matrix perceive photo apparatus, including camera, card
Computer assembly and touch tablet.
By cable connection between the camera and card computer assembly, the image data that camera is shot is transferred to
Card computer assembly.
The touch tablet includes haptic elements and rectangle outer housing, and the outer housing can also be set according to aesthetic feeling needs
Count into the other shapes such as square, ellipse, the haptic elements be can shake or the hollow-cup motor of lifting, the shell
Body upper surface is equipped with haptic elements, and haptic elements close matrix in outer housing upper surface arranges, and haptic elements are bonded in
Outer housing upper surface.
By cable connection, card computer assembly issues an instruction to control sense of touch for the card computer assembly and haptic elements
The on-off of element operation.
The haptic elements in outer housing at least 9 and matrix arrangement.
The card computer assembly includes card computer, connecting terminal block, display screen and power supply unit, the card computer
It is preferred that raspberry pie card computer (Raspberry Pi), by PIL in card computer (Python Imaging Library) come
The processing in terms of filter, the realization including sketch, pencil drawing, oil painting etc. filtering effects are carried out, PIL is mainly used to processing figure
Piece, it supports plurality of picture format.
The processing key of sketch filter is the lookup to edge.Pass through the lines of the available object of lookup to edge
Sense.After carrying out gray processing processing to image, we define a threshold value (threshold) first.Sketch it is main it is emphasised that
The variation of shading value, when drafting are oblique directions, and by experience, we are by the ash of the gray value of each pixel and its lower right corner
Angle value is compared, and when being greater than this threshold value, being judged as it is profile and draws.
Gray level image pretreatment is carried out with PIL, as long as we are L mode with convert function unsteady state operation.
Image gray processing is the R for making three kinds of color components of color, and the component value of G, B are equal, due to R, the value of G, B
Range is [0,255], so gray level image can indicate 256 kinds of gray scale face, color color image turns gray level method, and there are mainly three types of calculate
Method:
1. maximum value process (Maximum): so that the value of R, G, B is equal to the maximum one-component value in three color components, it may be assumed that R
=G=B=Max(R,G,B)。
2. mean value method (Average): the value of R, G, B being made to be equal to being averaged for three color components of three color components
Value, it may be assumed that R=G=B=(R+G+B)/3.
3. weighted average method (Weight Average): I encloses different power to R, G, B three-component respectively herein
Value indicates are as follows: R=G=B=WR*R+WG*G+WB*B, wherein WR, WG, WB are the weight of R, G, B respectively.Consider herein due to
Human eye to the susceptibility highest of green, take second place by red, minimum to the susceptibility of blue, therefore, as weight WG > WR > WB
When, generated gray level image more meets the visual experience of human eye.The library PIL uses ITU-R 601-2 luma transform:
L = R * 299/1000 + G * 587/1000 + B * 114/1000
That is WR=29.9%, WG=58.7%, WB=11.4%.
The card computer and camera and display screen pass through cable connection respectively, and the image of camera acquisition is in display screen
Interior imaging display, the card computer are connected with the shooting switch of control shooting, shoot the switch of switch for controlling photo
Selection.
The card computer and power supply unit connect with connecting terminal block, one terminals of the card computer and haptic elements
It is attached by connecting terminal block, another terminals of haptic elements and power supply unit are attached by connecting terminal block.
It is preferred that said supply unit supply another terminals operating voltage of haptic elements, the operating voltage direct current 3V or
5V, card computer issues control instruction to haptic elements, and low level issues.
It is preferred that another terminals of haptic elements are connect with power supply unit middle line, card computer issues haptic elements and controls
System instruction, and high level issues, and the voltage that sets out is direct current 3V or 5V.
According to the needs of controller, control instruction is issued to the corresponding haptic elements of needs movement, keeps its haptic elements dynamic
Make.
The outer housing and haptic elements upper surface are equipped with the silica gel thin film to match with outer housing and haptic elements, silica gel
The sense of touch of film opponent influences small, and dust can be effectively prevented or water is unrestrained on a touchpad.
The method of blind person's vibration and contacts matrix perception photo:
A) camera transfers data to card computer assembly by cable；
B) image of data transmission realizes gray level image pretreatment with PIL；
C) whole image is divided into several pockets；
D) touch tablet, which is equipped in region corresponding with each pocket and each region, is equipped with haptic elements；
E) image carries out surface by from left to right snake scan sequence；
F) in unit time, haptic elements shake in corresponding region on the black or white decision touch tablet of fritter respective pixel
Or whether life drop；
G) corresponding ports are arranged by code and switch set out vibration or lifting.
The whole image is divided into the pixel fritter that pixel is 3*3.
The advantages and positive effects of the present invention are: the present invention has structure simple, operation and easy to carry, pass through photograph
After piece turns sketch profile diagram, by sketch profile by vibrator on touch tablet or the technology of contacts matrix imaging, blind person can be made
The profile details information of apparent perception photo.
