Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
In an embodiment of the present application, as shown in fig. 1, a human body dimension measuring device is provided, the device includes at least one servo assembly 101, an annular bearing portion 102, and an antenna assembly 103, wherein the servo assembly 101 is connected to the annular bearing portion 102, and the antenna assembly 103 is disposed on the annular bearing portion 102.
The servo unit 101 and the annular carrier 102 described in the present application may be connected directly or indirectly to each other by indicating that the servo unit 101 and the annular carrier 102 are connected to each other. The antenna assembly 103 described in the present application is disposed on the annular bearing portion 102, and may indicate that the antenna assembly 103 is directly disposed on the annular bearing portion 102, and both are non-detachable integral; it may also be indicated that the antenna assembly 103 and the annular carrier 102 are two separate components, which may be coupled to each other in a matching manner, such that the antenna assembly 103 is disposed on the annular carrier 102.
In an embodiment of the present application, the servo assembly 101 may follow an external command to perform a desired motion, where the motion elements may include physical quantities such as position, speed, and moment. The external motion element fed back by the servo assembly 101 in the application can be mechanical displacement, displacement speed or acceleration, etc., and the servo assembly 101 is used for enabling the output external motion element to accurately track the input displacement, and the input displacement can be an external instruction input by people.
The servo assembly 101 is configured to drive the annular bearing portion 102 to move along a vertical direction, and send position information to the antenna assembly 103, where the position information is used to characterize a moving distance of the annular bearing portion 102.
In the embodiment of the present application, after receiving the external command, the servo motor 101 may move according to the displacement speed indicated in the external command, so as to drive the annular bearing portion 102 to move in the vertical direction. It should be noted that, when the annular bearing portion 102 in the present application moves in the vertical direction, the omnidirectional scanning of the human body can be achieved.
In an embodiment of the present application, the servo component 101 and the antenna component 103 may communicate through a wired or wireless manner. When the servo component 101 and the antenna component 103 are in a wired communication mode, the servo component 101 and the antenna component 103 can be connected through a data transmission line. When the servo component 101 and the antenna component 103 are in a wireless communication mode, radio frequency devices are respectively arranged on the servo component 101 and the antenna component 103, so that wireless communication can be performed between the servo component 101 and the antenna component 103.
When the servo assembly 101 drives the carrier to move in the vertical direction, the servo assembly 101 sends the moving distance of the annular carrier 102 to the antenna assembly 103 through wired communication or wireless communication with the antenna assembly 103, where the moving distance may represent the moving distance of the annular carrier 102 relative to the position before the annular carrier starts to move.
The antenna assembly 103 is configured to receive the location information, and transmit electromagnetic waves to the human body when the location information meets a preset condition, and receive electromagnetic waves reflected by the human body, where the electromagnetic waves reflected by the human body are used for an external computing device to calculate a size of the human body, and the electromagnetic waves are millimeter waves or terahertz waves.
After receiving the position information, the antenna assembly 103 determines whether the antenna assembly 103 needs to transmit electromagnetic waves to the human body. For example, the steps of transmitting electromagnetic waves to the human body and receiving electromagnetic waves reflected by the human body may be performed every 1 cm of movement of the ring-shaped carrier 102 detected by the antenna assembly 103. In the process of rotating the annular bearing part 102 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 is scanned in all directions, and all-direction scanning data of the human body are obtained.
In the embodiment of the application, the electromagnetic wave emitted to the human body is millimeter wave or terahertz wave, and the millimeter wave refers to the electromagnetic wave with the frequency of 30GHz to 300GHz and the wavelength of 1 millimeter to 10 millimeters. Millimeter waves are located in the wavelength range where microwaves and far infrared waves intersect, so that the microwave infrared light source has the characteristics of two wave spectrums. Terahertz waves refer to electromagnetic waves having frequencies in the range of 0.1THz to 10THz, and wavelengths between about 0.03 mm to 3 mm, between microwaves and infrared.
Millimeter waves have good penetration through many dielectric materials and non-polar substances, and can penetrate through any insulating material, including almost all kinds of cloth and most kinds of building materials. Terahertz radiation energy penetrates materials such as cloth, ceramic, fat, carbon plate, plastic and the like with small attenuation, and can be used for perspective imaging of an opaque object.
After transmitting the millimeter wave or the terahertz wave to the human body and receiving the millimeter wave or the terahertz wave reflected by the human body, the reflected millimeter wave or the terahertz wave can be utilized by an external computing device, which can establish a three-dimensional model of the human body according to the millimeter wave or the terahertz wave reflected by the human body and obtain the size of the human body according to the three-dimensional model of the human body.
The human body dimension measuring device comprises at least one servo component 101, an annular bearing part 102 and an antenna component 103, wherein the servo component 101 is connected with the annular bearing part 102, and the antenna component 103 is arranged on the annular bearing part 102; the servo assembly 101 is configured to drive the annular bearing portion 102 to move along a vertical direction, and send position information to the antenna assembly 103, where the position information is used to characterize a moving distance of the annular bearing portion 102; the antenna assembly 103 is configured to receive the location information, and transmit electromagnetic waves to the human body when the location information meets a preset condition, and receive electromagnetic waves reflected by the human body, where the electromagnetic waves reflected by the human body are used for an external computing device to calculate a size of the human body, and the electromagnetic waves are millimeter waves or terahertz waves. Because the human body dimension measuring device provided by the application moves once in the vertical direction through the annular bearing part 102, and simultaneously transmits electromagnetic waves to the human body and receives electromagnetic waves returned by the human body in the moving process, the human body can be completely scanned once, thereby obtaining the dimension of the human body, and greatly simplifying the whole operation process of measuring the dimension of the human body.
Optionally, in an embodiment of the present application, referring to 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, the receiving antenna array 1032 includes a plurality of receiving antennas 10321, the transmitting antennas 10311 for transmitting electromagnetic waves to the human body; the receiving antenna 10321 is used for receiving electromagnetic waves reflected by the human body.
In the embodiment of the present application, in order to realize comprehensive scanning of a standing human body, the antenna assembly 103 on the annular bearing portion 102 includes a plurality of transmitting antennas 10311 and a plurality of receiving antennas 10321 uniformly distributed on the annular bearing portion 102, and the distance between any two adjacent transmitting antennas 10311 and the distance between any two adjacent receiving antennas 10321 are smaller than a preset distance threshold, where the preset distance threshold can be adjusted according to actual requirements, so that the transmitting antennas and the receiving antennas are set, so that the bearing portion not only can perform multi-layer scanning on the human body in the vertical direction, but also can perform multi-angle scanning on the periphery of the human body. It should be noted that, in the present application, one inner side surface of the annular bearing portion 102 is close to the human body during the vertical movement, the other outer side surface is far from the human body, and the transmitting antenna array and the receiving antenna array included in the antenna assembly 103 are disposed on the inner side surface of the annular bearing portion 102 close to the human body.
Wherein, the number of transmitting antennas in the transmitting antenna array 1031 is equal to the number of receiving antennas in the receiving antenna array 1032, it should be noted that, although the transmitting antenna array 1031 and the receiving antenna array 1032 are disposed on the antenna assembly 103 side by side in the vertical direction, when disposed side by side, it should 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 a staggered manner in the corresponding vertical direction, and when distributed in a staggered manner, the 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 in the circumferential direction, so that the process of transmitting electromagnetic waves to a human body and receiving electromagnetic waves returned by the human body is realized.
In the embodiment of the present application, by arranging the transmitting antenna array 1031 and the receiving antenna array 1032, the transmitting antenna array 1031 includes a plurality of transmitting antennas, the receiving antenna array 1032 includes a plurality of receiving antennas, and the distance between any two adjacent transmitting antennas 10311 and the distance between any two adjacent receiving antennas 10321 are both smaller than a preset threshold value, and the distances between any two adjacent transmitting antennas and receiving antennas are equal, so that when the bearing part rotates, omnidirectional scanning is realized on a human body.
Optionally, in an embodiment of the present application, referring to fig. 3, the apparatus further includes a carrying table 104, where the carrying table 104 is used for carrying the human body, and a central axis of the carrying table 104 coincides with a central axis of the annular carrying portion 102.
In the embodiment of the present application, the purpose of the movement of the annular bearing portion 102 in the vertical direction is that the annular bearing portion 102 can perform complete scanning on a standing human body from top to bottom in the vertical movement process. When scanning a human body, a target area for accommodating the human body may be provided, and the target area may be a carrying table 104 or a predefined area range. It should be noted that, the central axis of the target area and the central axis of the annular bearing portion 102 are coincident, and the projection of the target area on the horizontal plane should be within the projection of the annular bearing portion 102 on the horizontal plane, so as to ensure that the annular bearing portion 102 will not collide with the human body during the movement process.
Alternatively, in an embodiment of the present application, the servo assembly 101 includes a motor and a belt; the servo assembly 101 is specifically configured to drive the driving belt to move by using the motor, so that the driving belt drives the annular bearing portion 102 to move along a vertical direction.
In an embodiment of the present application, the annular bearing 102 may be connected with a belt. When the driving belt is driven by the motor, the annular bearing part 102 can be driven to move at the same time. Two servo assemblies 101 and two drive belts are shown in fig. 1. In one possible implementation, the number of servo assemblies 101 may be one, and correspondingly, the number of belts may be one. When the number of servo assemblies 101 and the number of belts are plural, all servo assemblies 101 are synchronized in controlling the belts, and the position information may be transmitted to the antenna assembly 103 by only one servo assembly 101 of the plurality of servo assemblies 101.
In the embodiment of the application, the driving belt is arranged, so that the servo assembly 101 can transmit the generated movement behavior to the annular bearing part 102, and the annular bearing part 102 can rotate around a human body, thereby improving the practicability of the application.
Optionally, in an embodiment of the present application, referring to fig. 4, the antenna assembly 103 further includes a frequency source unit 1033; the frequency source unit 1033 for generating electromagnetic waves; the transmitting antenna 1032 is specifically configured to transmit 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, devices such as an amplifier, a frequency multiplier, a mixer, and a filter 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, and the frequency source unit 1033 generally generates an electromagnetic wave of a low frequency or an intermediate frequency first, and then up-converts the frequency of the electromagnetic wave of the low frequency or the intermediate frequency, so that the electromagnetic wave of the low frequency or the intermediate frequency is up-converted into the millimeter wave or the terahertz wave of the corresponding frequency band. Specifically, the devices such as an amplifier, a mixer, and a frequency multiplier in the frequency source unit 1033 may be used to up-convert electromagnetic waves of low or intermediate frequency. The frequency source unit 1033 is connected to the transmitting antennas in the transmitting antenna array 1031 and the receiving antennas in the receiving antenna array 1032 through a switch array, so that the transmitting antennas in the transmitting antenna array 1031 can transmit millimeter waves or terahertz waves generated by the frequency source unit 1033 to a human body.
In the embodiment of the present application, the frequency source unit 1033 may first generate the electromagnetic wave with low frequency or medium frequency, then gradually adjust the electromagnetic wave with low frequency or medium frequency, and finally obtain the millimeter wave or terahertz wave with the frequency meeting the requirement, thereby improving the flexibility of obtaining the millimeter wave or terahertz wave according to the present application.
Optionally, referring to fig. 5, in an embodiment of the present application, the antenna assembly 103 further includes a processing unit 1035; the processing unit 1035 is configured to receive the location information, and control the frequency source unit 1033 to generate electromagnetic waves when the location information satisfies the predetermined condition.
In the embodiment of the present application, the antenna assembly 103 includes a processing unit 1035, and a wired or wireless communication connection exists between the processing unit 1035 and the servo assembly 101, specifically, when a wired communication connection exists between the servo assembly 101 and the processing unit 1035, the servo assembly 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, radio frequency devices may be respectively located on the servo assembly 101 and the processing unit 1035, so that the servo assembly 101 and the processing unit 1035 may be wirelessly connected through the radio frequency devices.
After receiving the location information, the processing unit 1035 determines whether the location information meets a preset condition, and when the location information meets the preset condition, the processing unit 1035 controls the frequency source unit 1033 to generate electromagnetic waves, specifically, the processing unit 1035 may configure parameters for the frequency source unit 1033 to enable the frequency source unit 1033 to generate corresponding electromagnetic waves according to the configured parameters, where the configured parameters may include frequency points, frequency modulation intervals, transmit power, and the like.
In the embodiment of the present application, the processing unit 1035 determines the location information and configures parameters for the frequency source unit 1033, so that the frequency source unit 1033 can accurately generate the required electromagnetic wave according to the configured parameters.
Optionally, in an embodiment of the present application, the processing unit 1035 is specifically configured to control the frequency source unit 1033 to generate electromagnetic waves when the moving distance of the annular bearing portion 102 increases by a preset distance value.
In this embodiment of the present application, the processing unit 1035 may receive the position information sent by the servo assembly 101, where the position information indicates the moving distance of the annular bearing portion 102, and when the processing assembly determines that the moving distance of the annular bearing portion 102 increases by a preset distance value, the processing unit 1035 controls the frequency source unit 1033 to generate the corresponding electromagnetic wave.
For example, when the servo assembly 101 controls the annular carrier 102 to move in the vertical direction, the processing unit 1035 controls the frequency source unit 1033 to generate electromagnetic waves when detecting that the moving distance of the annular carrier 102 increases by 1 cm, 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 1 cm described in the application can be other values, and the preset distance value can be adjusted according to actual needs.
In the embodiment of the application, the processing unit 1035 is used for judging the moving distance of the annular bearing part 102, and the frequency source unit 1033 is controlled to generate electromagnetic waves when the moving distance of the annular bearing part 102 is increased by a preset distance value, so that the omnibearing scanning of multiple layers of human body is realized, and the finally measured human body size is more accurate.
Optionally, in an embodiment of the present application, the processing unit 1035 is specifically configured to control the frequency source unit 1033 to stop generating the electromagnetic wave when the moving distance of the annular bearing portion 102 reaches a preset threshold value.
In the embodiment of the present application, the condition that the frequency source unit 1033 stops generating the electromagnetic wave is set, and after the ring-shaped carrying part 102 completes one scan from top to bottom for the human body, it is equivalent to completing one complete scan for the human body, so that the frequency source unit 1033 can be controlled to stop generating the electromagnetic wave at this time. A specific operation may be that when the processing unit 1035 detects that the movement distance of the ring-shaped carrier 102 is greater than or equal to a preset threshold value compared to the initial position, the processing unit 1035 controls the frequency source unit 1033 to stop generating the electromagnetic wave, and the preset threshold value may be 2 meters, for example. Further, when the processing unit 1035 detects that the moving distance of the carrier portion reaches the preset threshold, for example, when the carrier portion detects that the moving distance of the annular carrier portion 102 is greater than or equal to 2 meters, a stop instruction may be sent to the servo assembly 101 through a communication connection with the servo assembly 101, so that after the servo assembly 101 receives the stop instruction, the annular carrier portion 102 is controlled to stop rotating.
In the embodiment of the application, the processing unit 1035 detects the moving distance of the bearing part and timely controls the frequency source unit 1033 to stop generating electromagnetic waves, so that repeated scanning of the human body is avoided, and the efficiency of measuring the human body is improved.
Optionally, in this embodiment of the present application, after the processing unit 1035 controls the frequency source unit 1033 to stop generating the electromagnetic wave, the servo assembly 101 is further configured to drive the annular bearing portion 102 to move along the vertical direction until the annular bearing portion 102 reaches an initial position, where the annular bearing portion 102 is located before the antenna assembly 103 emits the electromagnetic wave to the human body.
In the embodiment of the present application, after the ring-shaped carrying portion 102 performs one scan from top to bottom on the human body, the human body needs to return to the initial position. For example, when the initial position of the annular bearing 102 is 2 meters above the target area, the servo assembly 101 may control the annular bearing 102 to return to 2 meters above the target area after a complete scan of the human body is completed when the annular bearing 102 moves vertically from the initial position from top to bottom. Specifically, when the processing unit 1035 detects that the moving distance of the annular bearing portion 102 reaches the preset threshold, the frequency source unit 1033 is controlled to stop generating the electromagnetic wave, and further, the processing unit 1035 may send a return instruction to the servo assembly 101, where the return instruction may be used to instruct the servo assembly 101 to drive the annular bearing portion 102 to return to the initial position.
In the embodiment of the application, the servo assembly 101 can control the annular bearing part 102 to return to the initial position, so that a human body can conveniently enter and leave the human body dimension measuring device provided by the application, and the practicability of the application is improved.

In the embodiment of the present application, since the millimeter wave or the terahertz wave is emitted to the human body, the electromagnetic wave returned by the human body is also the millimeter wave or the terahertz wave, the frequencies of the millimeter wave and the terahertz wave are higher, and a higher sampling rate is required, so that the millimeter wave or the terahertz wave reflected by the human body can be completely sampled, and thus the millimeter wave or the terahertz wave reflected by the human body is converted into a digital signal, but in general, since the sampling rate of the electromagnetic wave with high frequency, which is suitable for the millimeter wave or the terahertz wave, cannot be directly generated, when the receiving antenna receives the millimeter wave or the terahertz wave reflected by the human body, and transmits the millimeter wave or the terahertz wave reflected by the human body to the down-conversion receiving unit 1034 through the switch array and the transmission line, the down-conversion receiving unit 1034 can firstly modulate the millimeter wave or the terahertz wave reflected by the received human body by using the method of quadrature demodulation, so that the millimeter wave or the terahertz wave with high frequency is converted into the analog signal with low frequency or the intermediate frequency, and the adjusted electromagnetic wave is obtained.

Then, the processing unit 1035 may also perform noise filtering operation on the obtained digital signal, specifically, a field programmable gate array chip (english: FPGA) may be present on the processing unit 1035, and then the noise filtering operation is implemented through the FPGA chip. The processing unit 1035 also collects the amplitude information and the phase information of the obtained digital signal, and sends the collected amplitude information and the collected phase information to the external computing device, so that the external computing device can build a three-dimensional model of the human body, and the human body size is calculated.
In the embodiment of the application, the millimeter wave or terahertz wave reflected by the human body is adjusted and processed through the frequency source unit 1033 and the processing unit 1035, so that the useful information is finally extracted from the millimeter wave or terahertz wave reflected by the human body, and the external computing equipment can calculate the size of the human body according to the useful information, thereby improving the accuracy of the application on data processing.

Specifically, referring to fig. 7, the processing unit 1035 may turn on the transmitting antenna 10311a and the receiving antenna 10321b through the switch array, then transmit electromagnetic waves to the human body by the transmitting antenna 10311a, and receive electromagnetic waves reflected by the human body by the receiving antenna 10321 b; after the transmitting antenna 10311a and the receiving antenna 10321b together perform an operation of transmitting electromagnetic waves to the human body and receiving electromagnetic waves reflected by the human body, the processing unit 1035 may continue to turn on the transmitting antenna 10311a and the receiving antenna 10321c through the switch array, perform an operation of transmitting electromagnetic waves to the human body and receiving electromagnetic waves reflected by the human body together by the transmitting antenna 10311a and the receiving antenna 10321c, and then, repeat the above-mentioned operation of transmitting electromagnetic waves to the human body and receiving electromagnetic waves reflected by the human body through the switch array.

Of course, in some possible implementations, when the moving distance of the annular bearing portion 102 increases by a preset distance value, the servo assembly 101 may control the annular bearing portion 102 to stop at the current position, and then the processing unit 1035 controls the plurality of transmitting antennas and the plurality of receiving antennas to be sequentially turned on and controls the frequency source unit 1033 to generate electromagnetic waves, so as to implement multi-angle scanning on the human body.
In the embodiment of the application, the processing unit 1035 controls the plurality of transmitting antennas and the plurality of receiving antennas to be opened in sequence, so that mutual interference of electromagnetic waves generated between the plurality of transmitting antennas and the plurality of receiving antennas can be effectively avoided, and the accuracy of measuring the human body size is improved.
