Description

  The present invention relates to measurement of a human body shape.

  Patent Document 1 discloses distance measurement using a high frequency. The intensity of a standing wave composed of a reflected wave and a traveling wave is measured while radiating a directional high frequency from an antenna and changing the frequency of the high frequency. When the intensity of the obtained standing wave is Fourier-transformed with respect to the frequency, the intensity of the standing wave with the distance to the object as a variable is obtained. For example, the distance to the object is determined from the maximum value of the intensity.

The inventors examined application of this technique to measurement of a human body shape, particularly measurement of a human body shape suitable for apparel. In this process, the inventor found the following. The time during which a person can maintain a certain posture is, for example, about 10 seconds. If the measurement is not performed within this time, the posture of the person is shaken and measurement becomes difficult. For this reason, it is necessary to measure at high speed. Also, the surface of the human body is not necessarily vertical, and when a beam is irradiated onto a surface inclined from the vertical, the reflected wave does not return to the antenna, making distance measurement difficult.
JP 2002-357656 A

An object of the present invention is to enable measurement of a human body shape at high speed and accurately.
An auxiliary problem of the present invention is to increase the accuracy of distance measurement.

  The human body shape measuring method of the present invention radiates a beam from a beam source toward the human body surface, measures the intensity of the standing wave based on the reflection of the beam on the human body surface while changing the frequency of the beam, In the method for determining the distance to the surface, a plurality of the beam sources are arranged in a ring shape so as to be movable up and down or linearly and rotated, and at least a part of the plurality of beam sources is oriented upward or / And, it is arranged downward.

  The human body shape measuring apparatus of the present invention radiates a beam from a beam source toward the human body surface, measures the intensity of the standing wave based on the reflection of the beam on the human body surface while changing the frequency of the beam, and A plurality of the beam sources are arranged in a ring shape so as to be movable up and down or linearly and rotated, and at least a part of the plurality of beam sources is directed upward or / and It is characterized by being placed downward.

  Preferably, more beam sources pointing downward with respect to the chest side of the human body are arranged than upward beam sources, and more beam sources pointing upward with respect to the back side of the human body are arranged than beam sources facing downward.

  The beam source is arranged in a ring shape that can be raised and lowered, for example, and the ring may or may not be provided with a slit for passing a person. Further, the beam source is arranged in a line shape such as about 1 to 4 straight lines so as to rotate around the human body. In addition to the high frequency shown in the embodiment, the beam may be an ultrasonic wave, and the principle of distance measurement may be Fourier transform or other.

  Preferably, the direction of the beam source with respect to the chest side of the human body is 30 ° to 10 ° upward from the horizontal plane, and the direction of the beam source with respect to the back side of the human body is 30 ° to 10 ° downward from the horizontal plane. To do. In this specification, the horizontal direction means an angle within ± 10 ° from the horizontal plane, and preferably means an angle within ± 5 ° from the horizontal plane. The downward direction is preferably 10 ° to 30 ° downward from the horizontal plane, more preferably 12 ° to 25 °, and the vertical direction is preferably upward 10 ° to 30 °, more preferably 12 ° to 25 ° from the horizontal plane.

  Preferably, in consideration of the loss time caused by rotating the beam source in the middle of scanning, the orientation of the beam source in the vertical plane is fixed, and the beam source facing downward with respect to the chest side of the human body A beam source is provided, and an upward beam source and a horizontal beam source are provided with respect to the back side of the human body.

  Note that the direction of the beam source may be freely swung in the vertical plane, and the upward / horizontal / downward direction may be switched in accordance with the direction of the beam source relative to the human body. In this way, the beam source in the direction where the distance from the human body cannot be obtained can be reduced and the measurement accuracy can be improved, but the measurement time becomes longer due to the rotation of the beam source.

  Preferably, scanning lines obtained by scanning the distance from the human body surface with each beam source are obtained, and the obtained distances are interpolated between the scanning lines of the distances.

  In the measurement of the human body shape according to the present invention, an upward or / and a downward beam is used in addition to the horizontal direction, so that the human body surface is not vertically formed and a standing wave is not easily formed with the horizontal beam. Can be measured. Since the plurality of beam sources are moved up and down or rotated and the distance from the human body is scanned with each beam source, the human body shape can be accurately measured in a short time.

  Here, if more beam sources pointing downward with respect to the chest side of the human body are arranged than the beam sources pointing upward and more beam sources pointing upward with respect to the back side of the human body are arranged than beam sources pointing downward, the front shoulder The distance from the human body can be measured even at a position where the reflected wave easily escapes diagonally upward, and the distance from the human body can be measured even at a portion where the reflected wave easily escapes downward, such as a bent part from the waist to the back. .

  The direction of the upward or downward beam is, for example, 10 ° to 30 ° from the horizontal plane, which is a numerical value determined empirically for the human body. In particular, when the angle is less than 10 °, standing waves are difficult to obtain at the front shoulder and the bent portion of the back, and when it exceeds 30 °, the upward and downward beams are not useful for measuring the vertical portion of the human body. . Therefore, if the inclination from the horizontal plane is 10 ° to 30 °, the human body surface can be used for distance measurement even in a place where the surface of the human body is close to a vertical position, such as near the shoulder or shoulder rib. The direction of the beam in the vertical plane may be fixed or variable.

  With a downward or upward beam, scanning line data may jump at portions where the human body shape is nearly vertical, and data may not be obtained. Also, with horizontal beams, data may fly at points where the human body shape deviates from vertical. Therefore, when the distances obtained from a plurality of beam sources are interpolated with each other, an accurate human body shape can be obtained as a whole.

  In the following, an optimum embodiment for carrying out the present invention will be shown.

  1 to 15 show an embodiment and its modifications. FIG. 1 shows the outer shape of the human body shape measuring apparatus 2. Reference numeral 3 denotes a stand for a person to stand, and reference numeral 4 denotes a frame surrounding the periphery of the apparatus. The annular lifting platform 8 is moved up and down along the column 6 and is preferably provided with 24 to 32, more preferably 16 to 64 horn antennas 10. The horn antenna 10 is a high-frequency antenna with little diffraction loss and is used as a radio wave antenna of about 28 to 30 GHz, and the type of antenna itself is arbitrary. Further, the measurement time of the human body shape is 10 seconds or less, and the lifting platform 8 moves up and down during this time.

  In the embodiment, as shown in FIG. 2, three types of horn antennas, horizontal, downward and upward, are used, 12 is a horizontal antenna, 13 is a downward antenna, 14 is an upward antenna, and the orientation in the vertical plane is fixed. It is. When the antennas 12 to 14 are shown as a whole, they are called the horn antenna 10, and when the antenna orientation is a problem, they are described as antennas 12, 13, and 14. Further, the horizontal direction means that the beam direction is within ± 10 °, preferably within ± 5 ° from the horizontal plane, and the downward direction is, for example, the downward direction from 10 ° to 30 °, preferably 12 ° to 25 ° from the horizontal plane. In the embodiment, the angle is 18 °. The upward direction is, for example, an upward direction of 10 ° to 30 ° from the horizontal plane, preferably 12 ° to 25 °, and an 18 ° direction in the embodiment.

  In the embodiment, the directions of the antennas 12 to 14 are fixed. However, the swing actuator 15 is provided, and the horn antenna 10 is rotated in the vertical plane within a range of ± 30 °, for example, from the horizontal plane to change the direction of the beam. Also good. In this case, for example, simultaneously with the raising and lowering of the lifting platform 8, the swing actuator 15 is operated to change the direction of the horn antenna 10, and the direction of the antenna is changed according to the direction with respect to the human body with one type of antenna.

  Returning to FIG. 1, the high frequency circuit 16 supplies a high frequency to the horn antenna 10, detects a standing wave of a traveling wave in the horn antenna 10 and a reflected wave from the human body, and removes a DC component, for example, Output to the signal processing unit 17. Since a plurality of horn antennas 10 are provided, in order to prevent mutual interference, the frequency is different for each antenna, or the horn antenna is used to pass radio waves deflected in a specific direction such as horizontal deflection or vertical deflection, It is preferable to change the direction of deflection by 90 ° between adjacent horn antennas. For example, if 32 horn antennas are used, 32 frequency sweep patterns are required to prevent interference only with the frequency, and 16 frequency sweep patterns are required when using deflection. The signal processing unit 17 is composed of a digital signal processor or a personal computer level signal processing circuit. For example, from the scanning line of the distance to the human body obtained by 32 horn antennas, A distance distribution is obtained, and this is subjected to signal processing to calculate a human body shape. The obtained human body shape is output to the monitor 18 or the like, and an input to the human body shape measuring apparatus 2 from the keyboard 19 is accepted.

  When the structure of the horn antenna 10 is shown in FIG. 3, reference numeral 21 denotes a waveguide, which receives a high frequency from a high frequency oscillation circuit and radiates a high frequency from a horn 22 whose tip is expanded. A pickup 23 is inserted into the waveguide 21 and detected by a detection circuit 24 such as a GaAs Schottky diode, and a DC component is removed by a DC eliminator 25 using a capacitor or the like and output. The DC eliminator 25 may not be provided. The standing wave detection pickup 23 may be provided in an antenna different from the horn antenna 10, but a high frequency waveguide or antenna is expensive, and the pickup 23 is provided in the transmission horn antenna 10. It is preferable.

  The arrangement of the antennas 12 to 14 is shown in FIGS. For example, the horizontal antenna 12 and the downward antenna 13 are mixed and arranged on the chest side of the human body 30, and the horizontal antenna 12 and the upward antenna 14 are mixed and arranged on the back side, for example. The horn antenna is disposed on the front and rear of the body 62 of the human body 30 and toward the surfaces of the right arm 63, the left arm 64, and the sides 65, 66. On the table, the person slightly expands both arms, and both arms and the sides 65, 66 are placed. A gap is formed between the sides 65 and 66 so that the positions of the sides 65 and 66 can be measured.

  FIG. 5 shows an elliptical lifting platform 9, which is preferable in that the distance from each antenna to the surface of the human body is made constant and measurement is easy. FIG. 6 shows the arrangement of horizontal measurement points 68, downward measurement points 69, and upward measurement points 70 in each part of the human body.

  FIG. 7 schematically shows the human body 30. On the chest side, the surface recedes round from the upper part of the chest to the shoulder, and the horizontal beam is reflected upward, making it difficult to detect standing waves. Therefore, when the beam is radiated downward, a standing wave is likely to be formed between the antenna and the human body surface. On the back side, the surface of the human body protrudes from the waist in the vicinity of the spine portion (for example, the shoulder rib), and the horizontal beam is reflected downward to make it difficult to detect the standing wave. Therefore, when an antenna is disposed upward and a beam is emitted upward, a standing wave is likely to be formed between the antenna and the human body surface. The chain line in FIG. 7 schematically shows the optimum beam direction at each position.

  For example, 32 scanning lines appear, for example, as solid lines in FIG. 8, and interpolation is performed taking into account the data on the left and right scanning lines in that data cannot be obtained due to an inappropriate beam direction. The interpolation may refer to the outline shape of the human body taken separately by a stereoscopic camera or the like. In order to measure the back shoulder correctly, it is advantageous to provide a downward antenna on the back side, and in order to cope with the case where the human body protrudes forward from the abdomen to the chest, an upward antenna is also provided on the front side. It is advantageous. Therefore, on the front side, in addition to the horizontal and downward antennas, upward antennas are also arranged. Here, a larger number of horizontal and downward antennas are provided than the upward antennas respectively, and on the back side, the horizontal and upward antennas are provided. In addition, a downward antenna may be provided, and a larger number of horizontal and upward antennas than the downward antenna may be provided.

  FIG. 9 is a block diagram of the human body shape measuring apparatus 2. A plurality of cameras 32 are provided, the same part of the human body is measured by two or more cameras 32, and an outline of the human body shape is obtained by the outline extraction unit 40. For example, four sets of two cameras 32 are provided so that stereoscopic images of the chest, back, left and right arms and sides of the human body 30 can be obtained. Note that instead of using a stereoscopic image by measuring the same location with a plurality of cameras, a spatial encoding method may be used, and slit-like light may be emitted from a light source to shoot.

  The elevator 8 is moved up and down by the lift drive unit 34, and the controller 36 controls the human body shape calculation unit 38, the lift drive unit 34, the outline extraction unit 40, the camera 32, and each horn antenna 10. The interpolation unit 39 provided in the human body shape calculation unit 38 uses data on the left and right scanning lines for points where there is no data on the scanning line or a point with low data reliability, and preferably the outline of the human body shape is used for this. Interpolating with the data obtained from For example, the distance from the horn antenna is measured about 128 to 512 times along the height direction of the human body.

  When a signal processing system for one horn antenna 10 is shown in FIG. 10, a high frequency output from the high frequency oscillation circuit 45 is radiated toward the human body 30 via the horn antenna 10. The high frequency used is, for example, about 28 to 30 GHz, and a relatively inexpensive high-frequency element for satellite communication or the like can be used. The beam diameter in a plane perpendicular to the traveling direction is, for example, about 2 cm, and the frequency sweep range is, for example, 1 It is about ~ 4GHz. A high-frequency traveling wave and a reflected wave exist in the horn antenna 10, and a standing wave is formed by these, and the ratio of the traveling wave is overwhelmingly large as energy.

  Then, the high frequency in the horn antenna is picked up by the pickup 23, detected by a detection circuit 24 using a GaAs Schottky diode or the like, for example, equivalent to a half wave, and a DC component is removed by a DC eliminator 25 comprising a high frequency capacitor. Most of the DC components are caused by traveling waves, and instead of removing the DC components with a capacitor, the DC components may be removed by subtracting or differentiating the signals after AD conversion.

  The signal from the DC eliminator 25 is fed back to the amplitude detector 42 and input to an ALC (automatic level control device) 43, and the difference from the reference value with respect to the amplitude is output. The output control unit 44 drives the high-frequency oscillation circuit 45 with a gain corresponding to the difference. The output of the high-frequency oscillation circuit 45 changes in a range of about 1/3 to 3 times the reference output, for example. As a result, feedback is applied to the output of the high-frequency oscillation circuit 45 so that the amplitude of the output signal from the DC eliminator 25 is substantially constant, whereby the standing wave power (output from the DC eliminator 25) is small. In this case, the power (energy) of the traveling wave is increased so that the standing wave can be detected without being buried in noise by the detection circuit 24.

  That is, it is difficult to detect a standing wave having a small amplitude in the presence of a traveling wave having a large amplitude, but the detection becomes easier if the amplitude of the standing wave is increased. When the output from the DC eliminator 25 is large, the traveling wave power is reduced to keep the signal intensity from the DC eliminator substantially constant, thereby preventing saturation of the detection circuit 24 and the like.

  The high-frequency circuit 16 changes the frequency to a plurality of, for example, 256 ways with respect to one measurement point, for example, changes the frequency to 28-30 GHz, etc. with respect to the center frequency 29 GHz, and enables Fourier transformation related to the frequency To do. Next, the ALC 43 is operated at the first frequency for one measurement point, and the output of the ALC 43 is kept constant at the same measurement point. Alternatively, the ALC 43 is operated independently for each frequency, and the used gain (the output of the ALC 43 and the output control unit 44) is input to the FFT 57 described later, and the ratio of the AD conversion signal to the gain is Fourier-transformed. Also good.

  In the frequency control, it is necessary to change the frequency in 256 steps during one sweep time of about several tens of milliseconds so that the frequencies of the 32 horn antennas 10 do not overlap. Therefore, for example, the frequency of each antenna is stored in 256 steps in the memory 52, the data read by the sequencer 51 is changed, converted into a frequency control signal by the digital synthesizer 53, and the like, and input to the high frequency oscillation circuit 45. The sequencer 51 and the memory 52 may be provided for each antenna, or may be provided for each of a plurality of antennas.

  The AD converter 55 performs AD conversion on the output signal of the DC eliminator 25, and the DC component in the AD converted signal is meaningless because it appears at the position of distance zero, and this is digitally processed by the DC eliminator 56. For example, after AD-converted signal is leveled down by a predetermined value corresponding to the DC component, Fourier transform is performed to obtain distance information.

  The FFT 57 performs Fourier transform on the signal obtained by AD conversion and further removing the DC component by fast Fourier transform or the like. This Fourier transform is a Fourier transform related to frequency, and as described in Patent Document 1, the peak of the Fourier transform signal corresponds to the distance from the antenna 10 to the human body. The AD-converted signal may be processed by a differential filter or the like to remove the DC component and input to the amplitude detector 42. Further, after the signal AD-converted by the AD converter 55 is Fourier-transformed by the FFT 57, the DC component may be removed by the DC eliminator 56. Further, instead of the Fourier transform, two frequencies at which the standing wave intensity is maximum may be measured, and the simultaneous equation of wavelength and distance may be solved to obtain the distance.

  The Fourier transform signal includes signals for reflection in the antenna and reflection in the background other than the human body. Therefore, the Fourier transform signal when there is no human body is stored in the background signal storage unit 58, and the difference from the Fourier transform signal when there is a human body is obtained by the difference unit 59. In this way, the effective part of the signal is extracted by removing the signal caused by the background from the Fourier transform. The tracking unit 60 uses other distance data on the scanning line, for example, distance data under one step, and then validates a distance within a predetermined range as a new distance. In the tracking unit 60, for example, when there are two peaks in the signal of the difference unit 59, the peak on the side where the distance is smoothly connected to other data on the scanning line is validated. If there is no appropriate peak within a predetermined range from other distance data, it is assumed that distance measurement data could not be obtained at that height.

  11 to 15 show the human body shape measurement operation. First, as a preparatory stage, a stereoscopic image of the human body shape is taken with a camera, and the starting height and ending height of the measurement are determined from this. If the moving height of the lifting platform for each step is constant, the number of steps is obtained, When the number is fixed, the change in height per step is obtained. In the embodiment, the upper body is shown to be measured, but the human body shape of only the upper body may be obtained or the human body shape of the whole body may be obtained. Furthermore, when measuring the human body shape of only the upper body, it is also possible for a person to sit on a chair or the like for measurement. From the stereoscopic image, the outline of the human body shape in the state of clothing is found, and if necessary, this data is the human body shape data measured using a horn antenna, and is used to supplement the unreliable part To do.

  FIG. 12 shows the measurement operation per horn antenna. Actually, the same operation is performed in parallel with, for example, 32 horn antennas as the measuring table rises. The ALC is operated in parallel with the elevation of the platform, the intensity of the detection signal is made constant, the frequency is changed in 256 steps according to the data from the memory, the intensity of the standing wave is obtained, and the Fourier transform is performed. The background signal is removed from the Fourier-transformed signal, and the maximum value of the Fourier-transformed signal within a predetermined range is obtained from the distance from the human body obtained at the previous step, in other words, one position below. If the maximum value of the Fourier transform signal exists within a predetermined range from the distance obtained under one step, this is used as distance data, and if the maximum value cannot be obtained, this process is repeated until the measurement end height.

  FIG. 13 shows the calculation of the human body shape after the distance measurement with the human body at each horn antenna is completed. Distance data is collected from each antenna and interpolated with data obtained with surrounding antennas for points with no data. Preferably, in this case, using the outline of the human body shape obtained by the outline extraction unit 40, for example, at a position where the human body should protrude forward from both neighbors, the average value of the data of both neighbors is projected slightly forward. In the position that should be recessed behind both sides, the interpolation is performed so as to be recessed slightly behind the average value of the data on both sides. In this way, the data measured by the antenna is interpolated so that consistency with the data of the outline extraction unit 40 is obtained.

  FIG. 14 shows the process from the measurement of the standing wave intensity to the calculation of the distance from the human body. When the intensity of the standing wave is obtained while changing the frequency f and is Fourier transformed, a Fourier transform signal having a variable d is obtained. Since the Fourier transform signal includes a background signal due to reflection other than the human body, this is stored and subtracted. From the signal thus obtained, a peak (maximum value) within a predetermined range with respect to the distance measured in one step is obtained. The reason why the predetermined range from one step below is a problem is that the distance between the human body and the antenna jumps discontinuously due to noise in many cases. Instead of using the distance obtained in one step as a reference, an average value of distances obtained in a plurality of previous steps may be used as a reference. In this way, as shown in the lower part of FIG. 14, a distance relationship with the height position is obtained, and this becomes a scanning line per antenna.

  FIG. 15 schematically shows an example of scanning lines. There are places on the surface of the human body that deviate from the vertical direction. In such places, an upward or downward beam is used in accordance with the direction of the human body surface, so distance measurement can be performed. And, for example, the distance can be measured with the horizontal beam, but the distance cannot be measured with the downward beam, refer to the distance with the horizontal beam and the distance at other positions on the scanning line of the downward beam. And the distance can be interpolated. Similarly, the distance can be interpolated even at a height at which the distance cannot be measured with the horizontal beam and the upward beam. If 32 scanning lines 72 can be obtained for the human body, the human body shape can be expressed with the same degree of precision as the human body shape is normally expressed by mesh mapping. In the upper part of the shoulder, it is difficult to accurately measure the distance unless the beam is greatly tilted downward. However, the outline extraction unit 40 can estimate the upper line of the shoulder and scan the upper part of the shoulder. The position of the upper line of the shoulder can be obtained because the data of the line is lost suddenly.

In the embodiment, radio waves such as microwaves are used, but the same measurement can be performed using ultrasonic waves. In the embodiment, the lifting platform is raised and lowered. For example, one to four poles may be prepared in the vertical direction, a plurality of horn antennas may be attached along the poles, and the poles may be rotated around the human body. .
