10. a kind of working method of Rotary three-dimensional foot type and plantar pressure scanner, it is characterised in that: the work side of scanner
Method the following steps are included:
Step 101: circumscripted power line plugs electricity, presses the switch button on scanner, scanner powers on and self-test；
Step 102: opening the test analysis software being mounted in interaction process terminal, select self calibration button, scanner enters
Self-calibration mode, the foot type scanning column on scanner are rotated around rack base lateral surface steady circular with scan protection pad, on
3D true feeling camera module in portion obtains the image data of neonychium, and self-calibration routines calculate the centre coordinate and area of neonychium,
Compare initial center coordinate and area again to calibrate the focal length of upper and lower part 3D true feeling camera module, origin, distortion
The inside and outside parameters such as parameter and calibration object world coordinates；
Step 103: enter user's log-in interface, new user registers first, inputted in interaction process terminal user name, gender,
The essential informations such as date of birth, height, weight simultaneously save, and enter back into scan pattern, it is laggard that existing subscriber selects user name to log in
Enter scan pattern；
Step 104: after entering scan pattern, user takes off footgear, and strip plays the bottom of s trouser leg, and both feet are separately stood in scanner gantry naturally
At the standing place mark of base protection pad, start to measure, the foot type scanning column on scanner is even around rack base lateral surface
Speed rotation one week, the upper and lower part 3D true feeling camera module of foot type scanning column cooperates acquisition user's biped when rotation
3 d image data is mounted on the synchronous plantar nervous arch data for obtaining user of pressure measurement plate of rack base centre；
Step 105: data collecting module collected 3 d image data and plantar nervous arch data in measurement Control card are simultaneously
Carry out analog-to-digital conversion, 3 d image data and plantar nervous arch data after cache module caching analog-to-digital conversion, central processing
Device such as is denoised to data and is encoded at the pretreatment, and pretreated data are passed through onboard data line by high speed data transfer module
It is transferred to interaction process terminal；
Step 106: data are stored, edit, calculate by test analysis software after interaction process terminal reception data etc.
Reason, the 3 d image data weight at instep, side and gap obtained by fusion upper and lower part 3D true feeling camera module
Structure goes out the three-dimensional foot type of user, extracts crucial three peacekeeping plantar pressure characteristic parameter of foot；
Step 107: interaction process terminal visualization shows the key characterization parameter of three-dimensional foot type and extraction, and storage result can also
Externally to share result by network interface or USB interface.
