Description
Technical field
The present invention relates to foot type data collecting field, while being related to customization field and the foot shield of Shoes and insoles class product
Reason field, and in particular to a kind of mode scanned with mobile phone photograph or mobile phone realizes accurate collection and the generation 3D of foot type data
The technical method of human foot model.
Background technology
" heart of human body second " that foot is approved as China and foreign countries' medical science, it is seen that its importance, the physiology structure of human foot
Although making similar, everyone foot type feature and size varies really.Currently, people are to foodcare and individual
The consciousness of people's health data is gradually strengthened, foodcare product, personalized footwear, footwear cushion class product, and personal health
The demand of data wearing is also in sustainable growth.
Some more traditional shoe industries produce the footwear and insole products that meet user's foot type for production, have started to use one
The measurement and foot type data acquisition of a little traditional carry out foot type.But due to traditional measurement mode because equipment is heavy, cost it is high (
100,000 or so/platform of RMB), the limitation of configuration, the space of measurement and network environment that needs professional manpower etc. limitation, and
Do not implemented well.
Most people lack oneself cognition to foot, and different foot type is in daily life to footwear, shoe-pad
Purchase, the mode of even foot care and nursing are all completely different.Therefore, how to enable people to it is both easy, quick, again
The foot's data of oneself are accurately obtained, this dresses and nursed for human foot, and conventional footwear R ＆ D Industry upgrading all ten
Divide important, but be not all well solved always before this.
Traditional foot data acquisition modes are roughly divided into 3 major classes：
1. manual measurement：It is complicated (linen measure tape, steel tape, metal marker, the high instrument of amount etc.) using instrument, it is in measurement such as amateur
Personage may cause the deviation of measurement result because of the error of measurement position, and voluntarily measurement operational feasibility is smaller, and work effect
Rate is low, labor intensity is big, operation difficulty is big, repetition rate is low, the error between gauger is big；
2. size stick：It for manual measurement, can be achieved voluntarily to measure, operate easier, but survey tool is portable
Property is slightly worse, and can only measure foot length, it is impossible to draw foot width and arch height data；
3. foot scanner：Based on laser scanning, launch laser rays from one or more lasing light emitters by certain frequency, use
Multiple video cameras draw foot data after shooting, collecting multiple image from different perspectives respectively, but equipment it is expensive (100,000 or so/
Platform), it is heavy that (machine weight about 40KG is, it is necessary to take up an area 1.5 square metres or so, and need to configure separate display screens combination machine
Operation), can only be used in fixed place and (need wifi connections to operate, because equipment heaviness is difficult to move, also be unfavorable for receipts
Put), meanwhile, equipment follow-up maintenance is costly.
The content of the invention
In view of this, the present invention provides one kind and two photos generation human foot models and pin is shot to foot by using mobile phone
Portion's sized data, everyone can easy manipulation, as long as mobile phone can people's complete independently, without huge equipment
The generation method of foot's data model of input.
The present invention solves above-mentioned technical problem by following technological means：
A kind of method of use mobile phone photograph scanning generation human foot model and data, comprises the following steps：
Step one：Pin is placed on standard A4 paper and taken pictures, it is ensured that pin is with A4 paper in the center of mobile phone screen；
Step 2：The center section of the captured photo of interception simultaneously carries out gray proces；
Step 3：Find out 3 angles of A4 paper, automatically generate coordinates matrix and calculate on whole pictures each pixel with
The relativity of real length；
Step 4：The most wide of foot's profile Y-axis is found out in A4 paper, X axis highest point obtains its pixel number
Amount, the value of the length in reality is contrasted by each pixel, calculates the length and width of pin；
Step 5：Mobile phone is laterally vertically against and is disposed vertically, collection of taking pictures is carried out to vacant background, and read the vacant back of the body
The color lump value of each pixel coordinate point in scape, is then stored in variable and is used as reference value；
Step 6：Pin side is put into shot region and carries out collection of taking pictures, and reads each picture in this time collection image
The color lump value of plain coordinate points；
Step 7：All pixels coordinate points color lump value in vacant background image is extracted to sit with the pixel in foot's side image
Punctuate color lump value is contrasted, and rejects identical color lump value in same coordinate point, if the color lump value in same pixel coordinate points is different
Then retain coordinate into new defined variable, foot's side coordinate profiles are finally sketched the contours of by reservation coordinate value；
Step 8：The maximum Lmax for retaining coordinate value in transverse coordinate axis in same longitudinal coordinate value is extracted, by plane
The foot length value drawn in profile is extracted and is defined as FL, and the existing each coordinate points length of definition is Ltrue, then Ltrue=FL/
Lmax*1mm；
Step 9：Show that foot side is whole by each pixel coordinate point length Ltrue and foot's side profile coordinate value
Body size (including arch height, instep height etc. parameter)；
Step 10：Foot top view and inner side view plane X-Y scheme and each data are built by above step, then build foot three
Dimension figure.
Further, mobile phone photograph is taken pictures using special APP.
Beneficial effects of the present invention：The present invention is solved and worked as while solution traditional measurement method data are not accurate enough
The space of preceding existing foot scanner and equipment use limitation.In terms of metering system, user need to be only used in mobile phone with this
The APP of technology, and 2 photos are shot to foot according to simple illustration, you can draw the length of foot, width, arch height,
The accurate datas such as instep height, it is easy to operate, quick, and can voluntarily measure, using instrument is simple, portability strong (mobile phone, A4
Paper), the error between gauger is avoided completely, and embodiment is repeatable to be reproduced, it is easy to is promoted, is solved traditional measurement mode
The upgrading of limitation, application and the personal grasp to individual data items to commercial field, and tradition footwear industry processed, all has
Very important meaning.
