Pin shape measuring instrumentTechnical field
The present invention is a kind of measurement device that relates to the technology such as optics, machinery, electronics, compunication, is the equipment of the high dimensional measurement problem of a solution pin type length and width.
Background technology
Measuring method refers to a kind of means of people's knowledge of natural environment circle things, for example: know the quality of certain piece metal, can measure with this instrument of balance, and balance be exactly a kind of method of measurement quality.Foot shape measurement refers to be measured the characteristic portion of pin, and the measurement of pin type comprises indirect measurement and directly measure, and by stepping on long measure etc. of pin that footprint figure carries out, all belongs to indirect measurement.
The factor that affects foot shape measurement has a lot.The concrete pin type for every a pair of, small variation can occur along with the variation of external condition in the size of pin.At first the left and right pin that it should be known that the people is substantial symmetry, and they are also incomplete same on length and degree of enclosing.For most people, the activity of right crus of diaphragm is greater than left foot, makes the length of right crus of diaphragm and degree of enclosing generally large than left foot.When carrying out foot shape measurement, generally all select right crus of diaphragm to measure.Certainly, when choosing footwear, should all to have a try by two pin, prevent unexpected the generation.Secondly human body is when bearing a heavy burden, and the size of pin also can change.Due to the heavy burden of human body, strengthened the bearing capacity of pin, arch is disappeared, thereby cause the variation on length and width.When people's body weight concentrates on a pin, increasing length adds the 3mm left and right, and width can increase by 2~5mm, and degree of enclosing can increase the 10mm left and right.When the design shoe tree, must consider the dynamic change of pin.When choosing footwear, should just not do and try on, also should stand up away and one walk.The variation in season is also influential to the size of pin again.During summer, be warm, the heat dissipation capacity of pin is also large, blood vessel dilatation, and the size of pin is bigger than normal; During winter, be cold, in order to reduce dissipation of heat, whole pin is all in contraction state, and the size of pin is corresponding less than normal.When foot shape measurement, generally all be selected in and carry out summer.Descendant's pin is in the situation that heel is padded, and size also changes.In general, along with calcaneal rising, the stressed increase of ball of foot, pin sole of the foot toe encloses long the increasing, and the sole heart is stressed, subtracts, and the bound feet instep encloses length and also reduces.The design high-heeled shoes, in during with footwear and flat heel, consider that the pin sole of the foot encloses this Changing Pattern enclosed with the pin instep.
Traditional pin type measuring method is all directly to measure.The girth meaurement of pin will be selected footwear belt chi.Footwear are the tapes of a long 50mm of wide 8mm with the belt chi, and front is centimeter scale, and the back side is Britain and French footwear sizes mark.Measured's right crus of diaphragm is steadily stood barefoot, by another people, is measured.Measuring process is as follows:
(1) first on pin, find each features site (on the first articulationes metatarsophalangeae, the 5th articulationes metatarsophalangeae, front shank bump, tuberosity of fifth metatarsal bone point, boat curved point, ankle the most carefully locate, the calf thickness, at one's knees under the fibula tuberosity along point).
(2) content of measuring by bottoms with the belt chi, measured one by one by the features site.
(3), while measuring six degree of enclosing, all require belt to maintain an equal level and be attached on skin, can not tension, can not be excessively loose.
(4), after the belt chi rounds, the intersection reading numerical values is each degree of enclosing value.
(5) record the numerical value of each degree of enclosing of measurement.
The measurement of the height of traditional pin is the size that each features site by pin obtains to the horizontal plane, measures pin when high, generally uses height measuring rule to be measured.Also can replace with longer ruler and set square.Measuring process is as follows:
While 1, using height gauge to measure, the pointer of height gauge can be aimed to the features site of pin, then sense data from height gauge.
While 2, using ruler, can directly measure at one's knees high, calf is high, ankle is high, high and heel bulging point is high along point under the Wai Huaigu center.
3, use that ruler measures that on boat, high, the front shank bump of curved point is high, the first articulationes metatarsophalangeae is high, thumb is when high, will after these characteristic point translations, with ruler, measure again with set square.
4, record each height number of measurement.
The electronic equipment of a measurement pin of the present invention type size, can directly obtain by the measurement of pin type each length, width and the elevation information of sole information.
Summary of the invention
The present invention is a kind of pin shape measuring instrument, and frame for movement is the linear array scanning driving device, and it comprises: motor, belt, guide rail, casing.Light-source structure comprises:, infrared lamp light source, infrared light transmission film, light transmission glass plate.The lighting mode is uniform annular or square lighting mode of surrounding.Electronic structure comprises: main control board, line scan image sensor, solution are sent out switch, USB port, USB information wire, power supply adaptor interface etc.IMAQ mode of the present invention is acquisition mode line by line, and the contour structures of invention has two kinds, and a kind of is flat, and another kind is right-angle type.The measurement of contour shape, length and width size, arch height under foot of flat pin shape measuring instrument major embodiment, and the major function of right-angle type pin shape measuring instrument is not the scan function of plate armature, also comprise the measurement of instep profile, each key position height dimension of instep.
Line scan image sensor is mainly used in gathering the sole image information, is one of main electronic component of the present invention.Line scan image sensor combines with belt, guide rail, then by the driven by motor belt, makes line scan image sensor do rectilinear motion in guide rail, in motion, gathers line by line image information.
The major function of infrared lamp light source, infrared light transmission film (filter coating, photomask), light transmission glass plate is that special lighting effect is provided when gathering image.The invention mid-infrared light source adopts 850 nanometers or 940 nanometer infrared light supplies, more easily by imageing sensor, is caught and catches light signal.The infrared light transmission film will encircle mirror light the impact of image itself will be intercepted beyond transparent glass.In order to guarantee the lighting effect of infrared lamp, power supply adaptor is separately the infrared lamp power supply.And the lighting mode has adopted uniform the going in ring or square sides lighting mode of surrounding.
