Abstract
A contact-type 3D foot shape measuring method is disclosed. Its device is composed of a sensor group which is an any of several linear displacement sensors, data aquisition unit and data processor. When a foot is set on said sensor array, the sensor array can output the discrete analog data of relative points. Through data acquision, A/D conversion, 3D graphic and data process and data smoothing, the various data about the foot are displayed by computer.
Description
The present invention relates to a kind of measuring method for foot shape, particularly relate to a kind of contact-type 3 D measuring method for foot shape.
People's foot is a very part and parcel of health, but because physiology cause, walking year in year out, a lot of people's foot all can produce distortion, severe patient more becomes deformity, cause walking inconvenience or fault when standing in view of the significance of foot for human motion, are used the high-tech measuring method and are measured human body foot shape, correct during the biological line of force hangs down, help the normal development of child's foot bones, prevention and rectification flat foot, the Physiological Analysis of launching a campaign, worldwide cause common attention, and can accurately measure for foot carries out three-dimensional, taking this to develop the strong product of medical treatment foot, will hold out broad prospects in medical and health industry and shoe industry.Chinese patent: the patent No. is ZL 98245724.3, the utility model patent that name is called " contactless foot scanning device " scans foot by laser scanning assembly, thereby read the foot three-dimensional data, but the certainty of measurement of this technical scheme is not high, the effect instability, and complex structure, need the cooperation of auxiliary equipment can lie low and just can read valid data with the person who happens to be on hand for an errand.
The purpose of this invention is to provide a kind of convenient, fast, simple in structure, certainty of measurement is higher, the contact-type 3 D of effect stability foot measuring method.
The object of the present invention is achieved like this, it comprises: sensor groups, data acquisition unit, data processor are formed, the vertical arrangement rectangular lattice formed by several Ф 4mm Linear displacement transducers of sensor groups wherein, centreline space between the Linear displacement transducer is divided into 15mm or littler, and for being equally spaced, data acquisition unit is by comparator, data acquisition single-chip microcomputer, and multichannel grammed switch, sample/hold circuit, A/D converter and programmable I/O interface is formed; Data processor is made up of the mechanical, electrical brain of date processing unit sheet.
The present invention is simple in structure, it is convenient to measure, linear because of Linear displacement transducer output and mechanical displacement, setting foot on when human body produces linear displacement, the discrete simulation quantity of sensor matrices corresponding point output on sensor matrices, through data acquisition, A/D is transformed into digital quantity, by date processing discrete data is fitted to 3-D graphic, reads Various types of data and figure, thereby certainty of measurement is higher, effect stability.
Below in conjunction with accompanying drawing the present invention is further described:
Fig. 1 is a FB(flow block) of the present invention;
Fig. 2 is a sensor groups rectangular lattice sketch map of the present invention.
As shown in Figure 1 and Figure 2, the present invention includes: sensor groups 1, data acquisition unit 2, data processor 3; The rectangular lattice of the vertical arrangement that sensor groups 1 is made up of the raster pattern Linear displacement transducer 4 of several Ф 4mm, centreline space between the raster pattern Linear displacement transducer 4 is divided into 15mm or littler, and for equidistantly distributing, the rectangular lattice area size of raster pattern Linear displacement transducer 4 is that 150mm * 300mm is enough to hold human foot, when people's foot is stepped in the measured zone, the linear displacement sensor 4 of each raster pattern is according to the difference of sole table shape, and output phase differs two road displacement signals of 90 degree; Data acquisition unit 2 is made up of comparator 5, data acquisition single-chip microcomputer 6, multichannel grammed switch 7, sample/hold circuit 8, A/D converter 9, programmable I/O interface 10, two tunnel displacement discrete analog(ue) quantity that differ 90 degree when sensing receiver group 1 output phase are to comparator 5, through data acquisition single-chip microcomputer 6, by multichannel grammed switch 7 and sample/hold circuit 8, be transformed into digital quantity by A/D changer 9, by programmable I/O interface 10 digital quantity be transferred to data processor 3 again; Data processor 3 comprises: date processing single-chip microcomputer 11 and computer 12, data processor single-chip microcomputer 11 fits to 3-D graphic with the digital quantity of collecting, and is transported to and reads Various types of data and figure in the computer 12.
Linear displacement transducer also can adopt capacitance-grid type.
