BEST MODE FOR CARRYING OUT THE INVENTION

Example 1

[0184] As shown in FIG. 1, a part or whole body contour data acquiring device is characterized in that it comprises a moving positioned point closely attached to the body, a measuring positioning device, a control circuit, and a data processing and storage device. , the moving positioning unit comprises an ultrasonic transmitting unit, the measuring positioning device comprises three fixed position ultrasonic receiving units, the three receiving units are distributed in an isosceles right triangle, and the control circuit comprises a transmitting unit of the transmitting unit or a receiving circuit corresponding to the receiving unit. . The moving position is stopped at a plurality of selected positions. During the stay, the transmitting unit transmits ultrasonic waves, each receiving unit separately receives, performs ranging by transmitting and receiving ultrasonic waves, and transmits the ranging data to the data processing and storage device, and the data The processing and storage device separately processes the ranging data of each parking position and calculates corresponding coordinate values and stores them.

[0185] The data processing and storage device includes a host computer and a lower computer, a lower computer, and a built-in fixed device, which can select a single chip microcomputer (MCU), a field programmable gate array (FPGA), a complex programmable logic device (CP). One or a combination of LDs, the host computer provides a PC, server or mobile terminal with a network connection. The upper computer and the lower computer are connected through the usb interface or the serial port. Of course, one of the one-chip computer (MCU), the field programmable gate array (FPGA), the complex programmable logic device (CP LD), or a combination thereof, which has a large computing capacity and a large memory capacity, can be directly selected as a data processing and storage device.

[0186] In this embodiment, the STM32F103RBT6 single-chip microcomputer is selected as the lower computer, and the personal computer is used as the upper computer to form a data processing and storage device.

[0187] The transmitting circuit is sequentially connected to a square wave generator module, a charge pump module or a power amplifying module. FIG. 6 is an example of a specific circuit of the transmitting circuit and the transmitting unit of the ultrasonic wave. The working principle is to input the GPIO of the STM32 from the R5. The high-level transistor is powered by the MAX232, and the STM32 advanced regulator is used to output two 40KHZ, 50% complementary PWM signals, which are input to the T1IN and T2IN of the MAX232 respectively, and the voltage is boosted by the MAX232 charge pump. The T40-16 ultrasonic transmitting unit is driven to excite ultrasonic waves of 40K HZ.

[0188] The receiving circuit corresponding to each receiving unit is sequentially connected to the 2-stage amplifier module, the filter module, and the ratio Comparator module, FIG. 7 is an example of a specific circuit of the receiving circuit and the receiving unit of the ultrasonic wave. The working principle is that the receiving unit R40-16 receives the ultrasonic signal and generates a small voltage signal at both ends of the pin, which is realized by the TL0 74. After the 2-stage amplifier module, the band-pass filter module, and the comparator module, and finally transmitted to the GPIO of the STM 32, the rising edge of the signal captured by the STM32's calibrator obtains the ultrasonic wave from the transmitting unit to the receiving unit.

[0189] In order to correct the change of sound speed caused by temperature change, the DB1820 temperature measuring circuit is used to detect the temperature and correct the sound speed.

, get a relatively accurate speed of sound.

[0190] In this way, the transmitting circuit drives the transmitting unit 吋, and the data processing and the resetting device of the storage device start counting; the receiving unit amplifies and filters the received ultrasonic wave, inputs the voltage comparator, and obtains the shaped voltage signal. After the rising edge or the falling edge of the signal is captured by the data processing and storage device, the counting is stopped, and the ultrasonic wave is obtained from the transmitting unit to the turn of the receiving unit, thereby realizing the transit time measurement.

[0191] The virtual coordinate system is established by the position of the receiving unit, and the coordinate value of each staying position of the moved positioned point in the virtual coordinate system can be calculated according to the ranging value between the moved positioned point and the measurement positioning device. details as follows:

[0192] Taking the receiving center of the right angle vertex receiving unit sensor distributed in an isosceles triangle as an origin, and passing the lines of the receiving centers of the other two receiving unit sensors as the X axis and the y axis, respectively, passing through the origin perpendicular to the X A straight line of the coordinate plane composed of the axis and the y-axis is taken as the z-axis, thereby establishing a Cartesian coordinate system, and the coordinates of the receiving unit are (0, 0, 0) (a, 0, 0) (0, a, 0), respectively, The positioning point is (X, Y, Ζ), and the ranging values are Rl, R2, and R3.

X2+Y2+Z2= R12

(X-a) 2+Y2+Z2= R22

Χ2+ (Y-a) 2+Z2= R32

[0196] Solving the equation means moving the positioning point coordinates.

[0197] As shown in FIG. 5, the moving positioned point includes an ultrasonic transmitting unit 2, a housing 1, a handle 4 and a button 5. The outer part of the housing is a spherical surface, and the base 3 is disposed inside the housing, the spherical center and the transmitting unit. The emission center is equal to the distance of the base 3, the transmitting unit 2 is soldered on the circuit board 6, the circuit board 6 is screwed to the base 3, the base 3 is mechanically connected to the handle 4, and the button 5 is mounted on the handle 4, the transmitting unit 2 And the button 4 is connected to the data processing and storage device control. [0198] Thus, it is structurally ensured that the center of the spherical surface coincides with the emission center of the transmitting unit. In the moving position of the moved point, the ranging instruction is sent by pressing the button to realize ranging and positioning. Taking a plurality of collected points as the center of the circle, the spherical surface set with the radius of the spherical surface of the positioned point is moved, and the inner curved surface of the envelope is the contour of the measured human body. This technique is used to effectively solve the emission center of the sensor. The technical problem of not meeting the contact surface of the human body contour improves the accuracy of the contour acquisition.

[0199] The above-mentioned partial or overall human body contour data acquiring device has the following working steps.

[0200] 1. Move the positioned point to stay at several selected positions, and press the button

[0201] 2. The transmitting unit transmits ultrasonic waves, each of which is separately received, and the distance is measured by the transmission and reception of the ultrasonic waves,

[0202] 3. Transfer the ranging data to the data processing and storage device,

[0203] 4. The data processing and storage device respectively processes the ranging data of each staying position of the moved point and solves the corresponding coordinate value and stores it.

[0204] 5. Repeat steps 2-5 until all selected position coordinates are obtained,

[0205] 6. Fit the coordinates of the dwell position of all the moved positioned points to the curved surface, that is, obtain the corresponding human body contour, [0206] or in the case where the radius of the moving positioned point housing is relatively large, the positioning is performed with all the movements. The dwell position of the point is the center of the circle, and the enveloping inscribed surface of the spherical surface which is calculated by moving the radius of the spherical surface of the positioned point is the accurate contour of the measured human body.

[0207] Based on this, it is applied to show clothes or shoes or caps or jewelry or glasses wearing effects, the steps are as follows

[0208] 1 additionally providing a virtual fitting service and a display and selection terminal, the virtual fitting server storing 3D models of different specifications of clothes or pants or hats or shoes or jewelry or glasses, using data processing and storage devices The upper computer is a display and selection terminal, the upper computer communicates with the virtual fitting server, and the upper computer and the lower computer of the data processing and storage device communicate via usb.
