Technical Field

[0002] In the medical diagnosis and evaluation of human body shape, human body size is an extremely important part. The requirements for surgical plastic surgery and effect evaluation, as well as the requirements for "customized body shape" are increasing. As a quantitative evaluation method of human body shape, medical human body three-dimensional measurement instruments can be used in large hospitals in large and medium-sized cities, and therefore have broad market prospects.

[0003] The existing three-dimensional human body measurement products are too expensive to be widely used. China Patent Application No. 201210456160.8 discloses a panoramic human body three-dimensional scanning system, which includes: 8 three-dimensional scanners, which are divided into 4 groups, and the 4 groups of three-dimensional scanning systems are arranged at 90 degrees with an interval of 0.8 to 1.5 meters from the scanned human body. The three-dimensional scanning systems are respectively connected to a computer, and the computer has a data output port. The lenses of the eight three-dimensional scanners face the direction of the human body target. However, the three-dimensional scanners used in the above scheme are eight, and the use of too many three-dimensional scanners increases the price of the product, which is not conducive to widespread use.

[0039] The working principle of the system of the present invention:

[0040] The present invention scans the human body to be measured standing on the scanning platform 4 through the annular scanner 7 and the mirror scanner 6 of the scanning unit 1. The annular scanner 7 and the mirror scanner 6 on the scanning platform 4 are started at the same time. Before the scanning starts, the height of the human body to be measured standing on the scanning platform 4 is measured by the height identifier 8 on the behavior reference device 5. According to the height of the human body to be measured, the display screen on the behavior reference device 5 displays a positioning contour line type with a ratio of 1:1 to the human body to be measured. The human body to be measured opens the body according to the positioning contour line type displayed on the display screen, and then the annular scanner 7 starts to scan the human body to be measured from top to bottom, and the mirror scanner 6 reciprocates in one direction to scan. The annular scanner 7 is driven to move up and down by the first linkage and the second linkage. The first linkage and the second linkage both include hydraulic lifting rods to achieve up and down movement.

[0041] The data acquisition module 101 disposed in the annular scanner 7 transmits part of the peripheral body shape data scanned by the annular scanner 7 to the body shape data storage module 2033 of the comparison processing module 203 for storage. The mirror scanner 6 has a built-in data processing module 601, which is connected to the data acquisition module 101. The data processing module 601 in the mirror scanner 6 transmits part of the peripheral body shape data scanned by the mirror scanner 6 to the body shape data storage module 2033 for storage. The part of the peripheral body shape data scanned by the annular scanner 7 and the part of the peripheral body shape data scanned by the mirror scanner 6 are complete peripheral body shape data of the first age group or the second age group. The mirror scanner 6 on the scanning platform 4 can scan body parts (such as armpits) that the annular scanner 7 cannot scan.

[0042] When comparing the peripheral body data of the first age group (young body, such as 18-28 years old) and the second age group (aging body, such as 35-50 years old) of the same person, the peripheral body data comparison module 2032 of the comparison processing module 203 obtains the peripheral body data of the first age group and the peripheral body data of the second age group stored in the body data storage module 2033, and compares the peripheral body data of the two age groups through the peripheral body data comparison module 2032, so as to obtain the peripheral body difference data between the two age groups, and then obtain the body deformation part corresponding to the peripheral body difference data.

[0043] The height value of the person to be measured standing on the scanning platform 4 identified by the height identifier 8 is obtained through the identification control module 9021, and the identified height value of the person to be measured is sent to the height data comparison module 2031. The height data comparison module 2031 calculates the difference between the identified height value of the person to be measured and each height value stored in the height data storage module 202, and screens out the height value with the smallest difference between the height value stored in the height data storage module and the identified height value. According to the height value with the smallest difference (the height value stored in the elevation processing module), the control module 9022 of the display control module 902 retrieves the positioning contour line data group stored in the positioning line contour data storage module 201, and transmits the positioning contour line data group to the behavior reference device 5 through the control module 9022. The positioning contour line type presented by the positioning contour line data group is displayed on the display screen of the behavior reference device 5.

[0044] The scanning control module 901 can control the start and stop of scanning of the annular scanner 7 and the mirror scanner 6 ; the movement control module 903 can control the up and down movement of the hydraulic lifting rod of the first linkage column 10 and / or the second linkage column 3 .

[0045] The data acquisition module 101 is electrically controlled or remotely controlled by the scanning control module 901 disposed at the bottom of the scanning platform 4. The electrical control is adopted to establish an electrical connection between the scanning control module 901 and the data acquisition module 101; the remote control of the data acquisition module 101 is adopted to respectively set a remote signal transceiver module on the scanning control module 901 and the data acquisition module 101, and a wireless signal transmission channel between the scanning control module 901 and the data acquisition module 101 is established through the remote signal transceiver module, and the scanning control module 901 is provided with a remote signal receiving module and a remote signal sending module for sending and receiving signals; the data acquisition module 101 is provided with a remote signal receiving module and a remote signal sending module for sending and receiving signals.
