Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Referring to fig. 1, the present application provides a human body dimension measuring device, which includes a servo assembly 101, a carrying portion 102 and an antenna assembly 103. The servo assembly 101 is connected to the carrying portion 102, and the antenna assembly is disposed on the carrying portion 102.
The servo unit 101 and the carrier 102 described in the present application may be connected to each other, and the servo unit 101 and the carrier 102 may be directly connected to each other or indirectly connected to each other. The antenna assembly 103 described in the present application is disposed on the carrier 102, and may mean that the antenna assembly 103 is directly disposed on the carrier 102, and both are an undetachable whole; it can also be said that there are two separate components between the antenna component 103 and the carrier 102, and the two components can be connected to each other in a matching manner, so that the antenna component 103 is disposed on the carrier 102.
The servo assembly 101 in the present application can follow an external command to perform a desired movement, and the movement elements thereof can include physical quantities such as position, velocity and moment. The external motion element fed back by the servo assembly 101 in the present application may be a mechanical displacement, a displacement velocity or an acceleration, and the servo assembly 101 is used to make the output external motion element accurately track the input displacement, where the input displacement mentioned here may be an external command input by a human.
The servo assembly 101 is configured to drive the bearing portion 102 to rotate around a human body, and send position information to the antenna assembly 103, where the position information is used to represent a rotation angle of the bearing portion 102.
In this embodiment of the application, after receiving the external command, the servo motor 101 may move according to the rotation angular velocity indicated in the external command, so as to drive the bearing portion 102 to rotate clockwise or counterclockwise around the human body. The motion around the human body described in this application refers to motion around a target area, which is provided in the human body dimension measuring device, and the target area may be a plummer. The target area may also be a predefined area range. The human body can stand in the target area, and when the servo assembly 101 drives the bearing part 102 to rotate around the target area, it is equivalent to that the servo assembly 101 drives the bearing part 102 to rotate around the human body.
It should be noted that the distance between the vertical central axis of the bearing portion 102 and the vertical central axis of the target area is greater than a first preset distance threshold, and the distance between the end of the bearing portion 102 close to the ground and the ground is greater than a second preset distance threshold, which is set to prevent the bearing portion 102 from touching the human body in the target area or touching the ground when rotating around the target area, thereby causing injury to the human body, damage to components, and measurement failure.
In the embodiment of the present application, the servo assembly 101 and the antenna assembly 103 may communicate with each other in a wired or wireless manner. When wired communication is provided between the servo assembly 101 and the antenna assembly 103, the servo assembly 101 and the antenna assembly 103 may be connected by a data transmission line. When wireless communication is performed between the servo assembly 101 and the antenna assembly 103, radio frequency devices are respectively present on the servo assembly 101 and the antenna assembly 103, so that wireless communication can be performed between the servo assembly 101 and the antenna assembly 103.
When the servo assembly 101 drives the carrier 102 to rotate around the human body, the servo assembly 101 transmits the rotation angle of the carrier 102 to the antenna assembly 103 through wired communication or wireless communication with the antenna assembly 103, and the rotation angle may represent the rotation angle of the carrier 102 relative to the position where the carrier 102 is located before the rotation starts.

After the antenna assembly 103 receives the position information, the antenna assembly 103 determines the received position information to determine whether to transmit the electromagnetic wave to the human body. For example, the steps of emitting electromagnetic waves to the human body and receiving electromagnetic waves reflected by the human body may be performed when the antenna assembly 103 detects that the carrier part 102 rotates every 0.5 degrees. In the process that the bearing part 102 rotates around the human body, the antenna assembly 103 can perform operations of transmitting electromagnetic waves to the human body and receiving electromagnetic waves reflected by the human body for multiple times, so that the human body can be scanned in all directions, and all-directional scanning data of the human body can be acquired.
In the embodiment of the present application, the electromagnetic wave emitted to the human body is a millimeter wave or a terahertz wave, and the millimeter wave refers to an electromagnetic wave having a frequency of 30GHz to 300GHz and a wavelength of 1 mm to 10 mm. The millimeter wave is in the overlapping wavelength range of microwave and far infrared wave, so that it has the characteristics of two wave spectrums. Terahertz waves refer to electromagnetic waves having a frequency in the range of 0.1THz to 10THz, and a wavelength of approximately 0.03 mm to 3 mm, which is between microwave and infrared.
Millimeter waves have good penetration into many dielectric materials and non-polar substances and can penetrate any insulating material, including almost every cloth and most kinds of building materials. Terahertz radiation can penetrate through substances such as cloth, ceramics, fat, carbon plates, plastics and the like with very small attenuation, and can perform perspective imaging on opaque objects.
After the millimeter waves or the terahertz waves are transmitted to the human body and received, the reflected millimeter waves or the terahertz waves can be utilized by external computing equipment, the external computing equipment can establish a three-dimensional model of the human body according to the millimeter waves or the terahertz waves reflected by the human body, and the size of the human body can be obtained according to the three-dimensional model of the human body.
The human body size measuring device comprises a servo assembly 101, a bearing part 102 and an antenna assembly 103, wherein the servo assembly 101 is connected with the bearing part 102, and the antenna assembly 103 is arranged on the bearing part 102; the servo component 101 is configured to drive the bearing part 102 to rotate around a human body, and send position information to the antenna component 103, where the position information is used to represent a rotation angle of the bearing part 102; the antenna assembly 103 is configured to receive the position information, transmit an electromagnetic wave to the human body when the position information satisfies a preset condition, and receive an electromagnetic wave reflected by the human body, where the electromagnetic wave reflected by the human body is used for an external computing device to calculate a size of the human body, and the electromagnetic wave is a millimeter wave or a terahertz wave. Because the electromagnetic wave that human size measuring device in this application launched to the human body is millimeter wave or terahertz wave, and millimeter wave and terahertz wave have can pierce through the clothing but can not pierce through the characteristic of human skin, so the human size measuring device that this application provided can accurately directly scan human body itself when launching the electromagnetic wave to the human body, the interference of external clothing has been avoided, thereby when making outside computing equipment utilize the electromagnetic wave of human reflection to calculate human body size, can accurately calculate human size itself, greatly reduced the error of carrying out the measurement to human size.
Optionally, in this embodiment of the application, the bearing part 102 is a vertical beam, as shown in fig. 2, the antenna assembly 103 includes a transmitting antenna array 1031 and a receiving antenna array 1032, the transmitting antenna array 1031 includes a plurality of transmitting antennas 10311 distributed in a vertical direction, the receiving antenna array 1032 includes a plurality of receiving antennas 10321 distributed in the vertical direction, where the transmitting antennas 10311 are used for transmitting electromagnetic waves to the human body; the receiving antenna 10321 is used for receiving the electromagnetic wave reflected by the human body.
In this embodiment, in the case that the carrying portion 102 is a vertical beam, in order to realize comprehensive scanning of a standing human body, the antenna assembly 103 on the carrying portion 102 includes a plurality of transmitting antennas 10311 and a plurality of receiving antennas 10321 distributed in the vertical direction, a distance between any two adjacent transmitting antennas 10311 and a distance between any two adjacent receiving antennas 10321 are both smaller than a preset threshold, and the preset threshold can be adjusted according to actual requirements, so that the transmitting antennas and the receiving antennas are arranged, so that the carrying portion 102 can not only perform multi-angle scanning around the human body, but also perform multi-layer scanning on the human body in the vertical direction. It should be noted that, in the present application, one side of the bearing part 102 is close to the human body, and the other side is far away from the human body, in the present application, the bearing part 102 is provided with the antenna assembly 103, and the transmitting antenna array and the receiving antenna array on the antenna assembly 103 are disposed on one side of the bearing part 102 close to the human body.
It should be noted that, although the transmitting antenna array 1031 and the receiving antenna array 1032 are arranged side by side on the antenna assembly 103 in the horizontal direction, when the transmitting antenna array 1031 and the receiving antenna array 1032 are arranged side by side, it needs to be noted that the transmitting antennas in the transmitting antenna array 1031 and the receiving antennas in the receiving antenna array 1032 need to be distributed in an offset manner in the corresponding horizontal direction, and when the transmitting antennas and the receiving antennas are distributed in an offset manner, distances between any two adjacent transmitting antennas and receiving antennas are equal. When the antenna assembly works, the transmitting antenna and the receiving antenna on the antenna assembly 103 are sequentially opened from top to bottom, so that the processes of transmitting electromagnetic waves to a human body and receiving the electromagnetic waves returned by the human body are realized.
In this embodiment of the application, by providing the transmitting antenna array 1031 and the receiving antenna array 1032, the transmitting antenna array 1031 includes a plurality of transmitting antennas distributed in the vertical direction, and the receiving antenna array 1032 includes a plurality of receiving antennas distributed in the vertical direction, and a distance between any two adjacent transmitting antennas 10311 and a distance between any two adjacent receiving antennas 10321 are both smaller than a preset threshold, and distances between any two adjacent transmitting antennas and receiving antennas are equal, so that when the carrying part 102 rotates, the human body is scanned in an omnidirectional manner.
Optionally, in the embodiment of the present application, as shown in fig. 3, the antenna assembly 103 further includes a frequency source unit 1033; the frequency source unit 1033 for generating electromagnetic waves; the plurality of transmitting antennas are specifically configured to transmit the electromagnetic waves generated by the frequency source unit 1033.
In the embodiment of the present application, the frequency source unit 1033 is specifically configured to generate millimeter waves or terahertz waves, and specifically, an amplifier, a frequency multiplier, a mixer, a filter, and the like may be present on the frequency source unit 1033. Because the frequency of the millimeter wave or the terahertz wave is high, the frequency source unit 1033 cannot directly generate the millimeter wave or the terahertz wave, when the frequency source unit 1033 generates the millimeter wave or the terahertz wave, generally, a low-frequency or intermediate-frequency electromagnetic wave is generated first, and then the frequency of the low-frequency or intermediate-frequency electromagnetic wave is up-converted, so that the low-frequency or intermediate-frequency electromagnetic wave is up-converted into the millimeter wave or the terahertz wave of the corresponding frequency band. Specifically, the amplifier, the mixer, the frequency multiplier, and the like in the frequency source unit 1033 may be used to up-convert the electromagnetic wave of the low frequency or the intermediate frequency. The frequency source unit 1033 is connected to the transmitting antenna in the transmitting antenna array 1031 and the receiving antenna in the receiving antenna array 1032 through the switch array, so that the transmitting antenna in the transmitting antenna array 1031 can transmit the millimeter wave or terahertz wave generated by the frequency source unit 1033 to the human body.
In this embodiment, the frequency source unit 1033 may generate low-frequency or intermediate-frequency electromagnetic waves first, and then gradually adjust the low-frequency or intermediate-frequency electromagnetic waves to obtain millimeter waves or terahertz waves with frequencies meeting the requirements, so as to improve the flexibility of obtaining millimeter waves or terahertz waves in this application.
Optionally, in the embodiment of the present application, as shown in fig. 4, the antenna assembly 103 further includes a down-conversion receiving unit 1034 and a processing unit 1035; the down-conversion receiving unit 1034 is configured to perform down-conversion on the frequency of the electromagnetic wave reflected by the human body to obtain an intermediate frequency signal after down-conversion; the processing unit 1035 is configured to perform analog-to-digital conversion and noise filtering on the down-converted intermediate frequency signal to obtain a processed signal, where the processed signal is used for the external computing device to calculate the size of the human body.
In the embodiment of the present application, since the millimeter waves or terahertz waves are emitted from the human body, the electromagnetic waves returned from the human body are also millimeter waves or terahertz waves, and the frequencies of the millimeter waves and terahertz waves are high, and a high sampling rate is required, so that the millimeter waves or terahertz waves reflected from the human body can be completely sampled, and thus the millimeter waves or terahertz waves reflected from the human body are converted into digital signals, but in general, since the sampling rate suitable for the high-frequency electromagnetic waves, such as the millimeter waves or terahertz waves, cannot be directly generated, when the receiving antenna receives the millimeter waves or terahertz waves reflected from the human body and transmits the millimeter waves or terahertz waves reflected from the human body to the down-conversion receiving unit 1034 through the switch array and the transmission line, the down-conversion receiving unit 1034 firstly performs frequency modulation on the received millimeter waves or terahertz waves reflected from the human body by using an orthogonal demodulation method, the high-frequency millimeter wave or terahertz wave is converted into a low-frequency or intermediate-frequency analog signal, and the adjusted electromagnetic wave is obtained.
In this embodiment, the down-conversion receiving unit 1034 and the processing unit 1035 may be communicatively connected through a transmission line, the down-conversion receiving unit 1034 may send the down-converted intermediate frequency signal to the processing unit 1035 through the communicative connection with the processing unit 1035, and the processing unit 1035 performs analog-to-digital conversion on the received down-converted intermediate frequency signal to obtain a corresponding digital signal. Then, the processing unit 1035 may further perform noise filtering operation on the obtained digital signal, specifically, a field programmable gate array chip (english: FPGA) may exist on the processing unit 1035, and then the noise filtering operation is implemented by the FPGA chip. And the processing unit 1035 will also collect the amplitude information and phase information of the obtained digital signals and send the collected amplitude information and phase information to an external computing device for the external computing device to build a three-dimensional model of the human body, thereby calculating the size of the human body.
Optionally, in this embodiment of the application, the down-conversion receiving unit 1034 and the processing unit 1035 adjust and process the millimeter waves or terahertz waves reflected by the human body, so that useful information is finally extracted from the millimeter waves or terahertz waves reflected by the human body, and therefore, an external computing device can calculate the size of the human body according to the useful information, thereby improving the accuracy of the application for data processing.
Optionally, in the present embodiment, the antenna element 103 further comprises a processing unit 1035; the processing unit 1035 is configured to receive the position information, and control the frequency source unit 1034 to generate an electromagnetic wave when the position information satisfies the predetermined condition.
In the embodiment, the antenna module 103 includes a processing unit 1035, and there is a wired or wireless communication connection between the processing unit 1035 and the servo module 101, specifically, when there is a wired communication connection between the servo module 101 and the processing unit 1035, the servo module 101 and the processing unit 1035 may be connected through a transmission line; when there is a wireless communication connection between the servo assembly 101 and the processing unit 1035, there may be a radio frequency device on each of the servo assembly 101 and the processing unit 1035, so that the servo assembly 101 and the processing unit 1035 may be wirelessly connected by the radio frequency device.
The processing unit 1035, after receiving the position information, determines whether the position information meets a preset condition, and when the position information meets the preset condition, controls the frequency source unit 1033 to generate an electromagnetic wave, and specifically, the processing unit 1035 may configure parameters for the frequency source unit 1033, so that the frequency source unit 1033 generates a corresponding electromagnetic wave according to the configured parameters, where the configured parameters may include a frequency point, a frequency modulation interval, a transmission power, and the like.
In the embodiment of the present application, the processing unit 1035 determines the position information and configures parameters for the frequency source unit 1033, so that the frequency source unit 1033 can accurately generate the required electromagnetic waves according to the configured parameters.
Optionally, in this embodiment, the processing unit 1035 is specifically configured to control the frequency source unit 1033 to generate electromagnetic waves when the rotation angle of the bearing portion 102 increases by a preset angle value.
In the embodiment of the present application, the processing unit 1035 may receive position information sent by the servo component 101, where the position information indicates a rotation angle of the carrying part 102, and when the processing component determines that the rotation angle of the carrying part 102 increases by a preset value, the processing unit 1035 controls the frequency source unit 1033 to generate a corresponding electromagnetic wave.
For example, the servo component 101 controls the carrier 102 to rotate around the human body at a constant speed, and when the processing unit 1035 detects that the rotation angle of the carrier 102 increases by 0.5 degrees every time, the frequency source unit 1033 is controlled to generate electromagnetic waves, so that the frequency source unit 1033 transmits the electromagnetic waves to the human body through the transmitting antennas in the transmitting antenna array 1031, and receives the electromagnetic waves reflected by the human body through the receiving antennas in the receiving antenna array 1032. Of course, the 0.5 degree described in the present application may be other values, and the preset angle threshold may be adjusted according to actual needs.
In the embodiment of the present application, the processing unit 1035 is used to determine the rotation angle of the bearing part 102, and control the frequency source unit 1033 to generate electromagnetic waves when the rotation angle of the bearing part 102 increases the preset angle value, so that the human body can be scanned in all directions at multiple angles, and the final measured size of the human body is more accurate.
Optionally, in this embodiment, the processing unit 1035 is specifically configured to control the frequency source unit 1033 to stop generating the electromagnetic wave when the rotation angle of the bearing portion 102 reaches a preset threshold.
In the embodiment of the present application, the condition that the frequency source unit 1033 stops generating electromagnetic waves is set, and after the carrying portion 102 rotates around the human body for one circle, it is equivalent to that the human body has completed one complete scan, so that the frequency source unit 1033 can be controlled to stop generating electromagnetic waves at this time. Specifically, when the processing unit 1035 detects that the rotation angle of the supporting portion 102 is greater than or equal to 360 degrees compared to the initial position, the processing unit 1035 controls the frequency source unit 1033 to stop generating the electromagnetic wave.
