Description

Technical Field

[0001] The invention belongs to the technical field of laser measurement, in particular to a laser measurement camera monitoring system. Background Art

[0002] When a large-scale important event is held in the jurisdiction, or when dangerous persons appear and threaten public safety; in order to maintain public safety, it is necessary to check the people coming and going at the entrances and exits of important transportation places, so as to find and arrest the relevant dangerous persons in time; at the same time, it is also to prevent passengers from carrying dangerous items in and out and threatening public safety.

[0003] When security management personnel check people entering and leaving intersections, they generally use manual means or intelligent image recognition methods to collect people's characteristic information through cameras installed in the surrounding area, compare them with the database, and eliminate dangerous people; they also mark possible suspects and then further check them through manual means to ensure public safety.

[0004] In addition to facial information, these feature information also includes physical data such as height, foot shape, arm length, shoulder width, etc. These physical data are also important references when screening dangerous persons. In existing practices, security management personnel find that when there are many people, they are crowded together, and the blocking and shielding caused by clothing makes it difficult to effectively collect facial information of people coming and going. The facial information of dangerous persons collected in the past may also be difficult to identify in time due to differences in disguise.

DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings shown in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0041] Embodiment one:

[0042] When a large important activity is held in the jurisdiction, or dangerous personnel are present to threaten public safety; in order to maintain public safety, it is necessary to check the personnel coming and going at the entrance and exit of important traffic places, so as to timely appear and capture related dangerous personnel; at the same time, it is also to prevent passengers from carrying dangerous goods to enter and exit, threatening public safety;

[0043] When the safety management personnel check the personnel coming and going at the intersection, they generally use manual means or intelligent image recognition means to collect personnel feature information through the cameras set around, compare in the database, exclude dangerous personnel, and mark the possible suspicious personnel, and then further check by manual means to ensure public safety;

[0044] These feature information includes not only facial information, but also body data such as height, foot type, arm length, shoulder width, etc. These body data are also important reference when checking dangerous personnel. In existing practice, when the safety management personnel find that there are many people, mutual congestion, mutual obstruction and shielding caused by adding clothes, it is difficult to effectively collect the facial information of the passing personnel. The facial information of the dangerous personnel collected in the past may also differ due to disguise, which is difficult to identify in time. At this time, the body data of the dangerous personnel measured and collected in the past can be used as an important reference to help timely narrow the scope of suspicious personnel and improve the accuracy of search;

[0045] However, the existing measurement of the physical appearance data of the to-be-measured personnel is mainly carried out by manual means, which is low in efficiency and prone to errors and omissions in the operation process. Some personnel are also resistant to physical contact inspection, which may cause slow passage and congestion at the intersection, which is not conducive to the investigation of dangerous factors and may also cause congestion hazards, which is not conducive to the maintenance of public safety.

[0046] To effectively solve the above problems, as shown in the drawings Figures 1-9 The application provides a laser measurement and camera monitoring system, which comprises a monitoring measurement channel 1 and a laser three-dimensional scanner 6. The laser three-dimensional scanner 6 is used to collect data of the face and body information of the personnel passing through the monitoring measurement channel 1, including face information and measurement of the size of the body parts. The monitoring measurement channel 1 has a semi-closed structure and its surface is treated to be opaque. Openings are arranged on the two sides of the monitoring measurement channel 1, and the vertical cross section is in a square ring shape. Safety cameras 11 are arranged on the top of the openings on the two sides of the monitoring measurement channel 1 to take pictures of the personnel entering.

[0047] A positioning seat 2 is arranged in the rotating groove 12 at the middle position of the bottom of the monitoring measurement channel 1. The laser three-dimensional scanner 6 is arranged at a position opposite to the positioning seat 2 on the side wall of the monitoring measurement channel 1, and a rotating motor is arranged at the connecting position, so that the angle of the laser three-dimensional scanner 6 can be adjusted as needed. The driving end of the rotating device arranged at the bottom of the rotating groove 12 is connected to the positioning seat 2. The driving end can be a driving motor, which is controlled by a control center. A footprint-shaped indicating groove 21 is arranged on the upper surface of the positioning seat 2.

[0048] A display interface 5 is arranged outside the monitoring measurement channel 1. The display interface 5 is provided with a display screen and control buttons. The control center is arranged in the display interface 5 to control the operation of the components.

[0049] Specific working process: when it is necessary to investigate the passing personnel and maintain public safety, the movable monitoring measurement channel 1 can be directly arranged at the intersection. The safety management personnel can maintain order at the openings on the two sides of the monitoring measurement channel 1. The passing personnel can be automatically investigated during the passing process of the monitoring measurement channel 1, and dangerous personnel can be captured in time to avoid the damage and harm to public safety caused by the illegal persons.

[0050] The safety cameras 11 arranged at the openings on the two sides of the monitoring measurement channel 1 can take pictures of the to-be-measured personnel and transmit the collected face image data to the database for comparison to investigate whether the to-be-measured personnel are dangerous personnel.

[0051] Further, after the to-be-measured person enters the monitoring measurement channel 1, the to-be-measured person is positioned on the positioning seat 2 in the middle position according to the prompt, and the two feet are stepped on the foot-print-shaped indicating groove 21, so that the position of the to-be-measured person is positioned; the laser three-dimensional scanner 6 opposite to the positioning seat 2 is started, the laser three-dimensional scanner 6 is provided with a transmitting end and a receiving end, the transmitting end can emit a large amount of ranging laser, covering the body surface of the to-be-measured person located on the upper side of the positioning seat 2 in the opposite direction, part of the laser is reflected after contacting the body surface and is received by the receiving end, the time of laser emission and reflection reception is recorded, the data of each part of the body surface of the to-be-measured person is scanned and collected, and is fed back to the internal analysis modeling software, so that the facial features and body features of the to-be-measured person are modeled, so that on the basis of fully collecting and identifying the facial information of the to-be-measured person, the height, arm length, leg length, chest width and other data of the to-be-measured person are effectively collected, and are compared with the suspect in the database, and the image shooting of the security camera 11 is cooperated, so that the identity information of the to-be-measured person is verified in multiple dimensions, the identification accuracy is effectively improved, and the misleading data such as disguise and plastic surgery is excluded, so that whether the to-be-measured person belongs to dangerous personnel is more accurately investigated;

[0052] Further, the rotating device at the bottom of the positioning seat 2 can be started to rotate and drive the positioning seat 2 and the to-be-measured person on the upper side to rotate, so that the body projection of the to-be-measured person at different angles can be effectively reflected on the projection plate 3, the body projection information of the to-be-measured person is more comprehensively collected by the collection camera 41, the projection of the to-be-measured person at multiple angles such as the front and the side is measured, more comprehensive body feature data is obtained, and the investigation accuracy is further improved;

[0053] Meanwhile, because the foot-print measuring device is arranged on the indicating groove 21 to measure the foot information of the to-be-measured person, when the to-be-measured crowd is too large, the to-be-measured person can directly step on without taking off shoes, the size of the shoe-print is measured to judge the code number, so that the size of the foot of the to-be-measured person is calculated; for the personnel with greater suspicion, the personnel should be notified to directly stand up after taking off shoes, so that more accurate foot information is calculated; as an important body feature, the measured foot information can be used as an important reference data for investigating dangerous personnel, and the accuracy of investigating dangerous personnel is improved;

[0054] Compared with manual measurement and collection of body feature data, the application further improves the investigation efficiency of the passing personnel by collecting human feature data through laser scanning, avoids congestion, reduces the error that may occur in the manual measurement process, and provides more reliable guarantee for public safety.

[0055] Embodiment two:

[0056] On the basis of embodiment one, the footprint measuring device used in the present application has multiple possible implementation schemes, and any device capable of accurately measuring footprints in the prior art can be applied to the present application. Here, a possible implementation scheme is provided.

[0057] Specifically, the footprint measuring device includes a measuring scale 22. A measuring cavity 23 is arranged inside the positioning seat 2, and the measuring cavity 23 is located below the indicating groove 21. The bottom of the indicating groove 21 is a mesh structure and is in communication with the inside of the measuring cavity 23. The measuring scale 22 is installed at the top of the measuring cavity 23 and is located on both sides of the indicating groove 21. A shooting device 24 is arranged at the bottom of the measuring cavity 23, and the working end is arranged upward.

[0058] A cleaning cavity 25 is arranged inside the positioning seat 2. A suction device is arranged at the middle position of the cleaning cavity 25. Here, the suction device can be a miniature air pump device controlled by the control center. Suction grooves 251 are uniformly arranged on the side wall of the measuring cavity 23 and are in communication with the inside of the cleaning cavity 25. A filter screen is arranged at the middle position of the cleaning cavity 25 to separate the communication part of the suction grooves 251 and the installation part of the suction device, so as to avoid the interference of the suctioned dust and impurities with the normal operation of the suction device. A blocking ring 252 is arranged between the shooting device 24 and the suction grooves 251.

[0059] Specific working process: on the basis of the specific working process in embodiment one, when the person to be measured stands on the positioning seat 2, according to the prompt, the feet are stepped on the indicating groove 21. At this time, the bottom of the indicating groove 21 is arranged as a mesh structure, which facilitates the shooting device 24 below to shoot the contour of the entire foot from the lower to the upper through the gap hollow part of the mesh structure. Because the measuring scale 22 is arranged at both sides of the indicating groove 21, the measuring scale 22 and the feet of the person to be measured are shot together. The measurement scale on the measuring scale 22 can be used as a reference for measurement. After being transmitted to the control interface, the length and width of the feet and other data are obtained through the related measurement software. Then, the measured foot data is transmitted to the control center and the database. Combined with the body data and facial portrait data obtained by projection measurement, the data is comprehensively screened to determine whether it belongs to dangerous personnel, so as to improve the accuracy of screening and further protect public safety.

[0060] Further, the existing foot information collection device has a contact surface with the foot, which is mostly a sensing plate device. The foot information is displayed through pressure sensing. Because the contact part is easy to be damaged, it is generally recommended to measure after taking off the shoes to avoid damage to the device. This is not conducive to quickly measuring the queuing personnel in a short period of time. Therefore, in order to improve the efficiency, the present application can directly step on the mesh structure at the bottom of the indicating groove 21 without taking off the shoes, which can increase the friction and avoid sliding.

[0061] On the other hand, because the net structure adopts transparent material, the permeability is improved, the net structure separates the shooting device 24 and the feet of the person to be measured, indirect measurement is realized, the shooting device 24 which actually plays a measuring role is not damaged in the process of information collection; even if the net structure is worn out due to repeated treading and is no longer transparent, because the ropes that constitute the net structure are thin, the hindrance is small, the shooting device 24 at the bottom can pass through the hole gap of the net structure and fully shoot the sole contour of the person to be measured, and normally play a role; compared with the prior art, the application is more suitable for efficient measurement of a large number of people, and the service life is improved.

[0062] Further, during the measurement process, the air suction device located inside the cleaning cavity 25 is started, so that when the dust and sundries on the sole of the person to be measured enter the measurement cavity 23 during the measurement process, they are sucked into the dust suction groove 251 under the action of air suction, and then enter the inside of the cleaning cavity 25 to be collected, and the inside of the shooting device 24 and the cleaning cavity 25 is cleaned at regular intervals, so as to avoid the dust and sundries on the sole of the person to be measured from interfering with the normal work of the measuring device and affecting the measurement of the information of the sole of the person to be measured.

[0063] Further, the blocking ring 252 located between the shooting device 24 and the dust suction groove 251 is inclined on the side close to the shooting device 24 and vertical on the side close to the dust suction groove 251, so that when the dust and sundries falling into the measurement cavity 23 are acted on by the air suction through the gap on the upper side of the blocking ring 252, the dust and sundries are caused to slide along the inclined surface of the blocking ring 252 and enter the side of the dust suction groove 251, and even if the dust and sundries do not enter the dust suction groove 251 smoothly or flow out of the dust suction groove 251, they will be blocked by the vertical surface of the blocking ring 252, so that they cannot interfere with the normal work of the shooting device 24.

[0064] Embodiment three:

[0065] On the basis of embodiment one, the part of the side wall of the measurement channel 1 opposite to the positioning seat 2 is respectively provided with a projection plate 3 and a led lamp plate 4, and the projection plate 3 and the led lamp plate 4 are respectively located on the two sides of the positioning seat 2, the surface of the projection plate 3 here adopts the material commonly used in the projection process, for example, a projection screen, to form a clearer image, and the edge part of the surface of the projection plate 3 is uniformly provided with a measurement scale; the led lamp plate 4 is provided with led light equipment, which can emit parallel light to facilitate imaging; the projection plate 3 is located below the laser three-dimensional scanner 6, and the upper side of the led lamp plate 4 is provided with a collection camera 41 to collect the projection information of the person on the upper side of the projection plate 3.

[0066] Specific workflow: on the basis of the specific workflow in embodiment one, on the basis of determining the body feature information of the to-be-measured person through laser scanning, in order to further improve the accuracy of information collection, the information of the to-be-measured person can be collected in various ways, for example, by using the projection measurement method, specifically, the led lamp plate 4 is started, parallel light is emitted, the parallel light transmits through the to-be-measured person and is irradiated on the projection plate 3, then the body of the to-be-measured person is projected on the projection plate 3, which facilitates the measurement of the physical features of the to-be-measured person;

[0067] Specifically, under the instruction of the safety management personnel, the to-be-measured person stands straight on the positioning seat 2, spreads his arms, and the projection on the projection plate 3 can clearly display the physical features of the to-be-measured person; then after collecting the projection information by the collection camera 41, according to the measurement scale line provided on the projection plate 3 as a reference, through the related measurement software, the height, arm length, leg length, chest width and other data of the to-be-measured person can be effectively measured, which is convenient for evaluating the fatness degree of the to-be-measured person and whether there is a defect such as lameness, so as to compare the data of the dangerous person in the database by combining the face portrait information and the human body model data collected and constructed in the laser scanning measurement process, which is conducive to excluding misleading data such as disguising and plastic surgery, so as to more accurately investigate whether it belongs to a dangerous person; and this measurement method is more intuitive, which is convenient for the safety management personnel on one side to directly judge the physique of the to-be-measured person, and is convenient for the work of the safety management personnel;

[0068] Further, because the monitoring and measuring channel 1 adopts a light-proof material and a semi-closed structure, it effectively blocks the entry of external light, reduces the interference of external light on the imaging on the projection plate 3, makes the projection imaging on the projection plate 3 clearer, and makes the measurement of the physical features of the to-be-measured person more accurate, thereby improving the accuracy of the investigation.

[0069] Embodiment four:

[0070] On the basis of embodiment three, a sliding groove 13 is vertically arranged at the middle part of the led lamp plate 4 on the side wall of the monitoring and measuring channel 1, and a sliding block 14 is slidingly installed in the sliding groove 13; a measuring plate 15 is arranged at the upper side of the positioning seat 2, the measuring plate 15 is connected with the sliding block 14 through a connecting rod, a detection plate 16 is arranged on the measuring plate 15, and a detection device is arranged on the detection plate 16;

[0071] The surface of the measuring plate 15 is transversely provided with an adjusting groove 151, and an adjusting block 152 is slidingly installed in the adjusting groove 151, the number of the adjusting block 152 is two, and the adjusting block 152 is located at both sides of the adjusting groove 151 respectively; the number of the detection plate 16 is two, and the detection plate 16 is located at both sides of the positioning seat 2 respectively;

[0072] And the detection plate 16 is connected with the adjusting block 152 on both sides respectively; the cooperation between the above-mentioned sliding groove 13 and the sliding block 14, and the cooperation between the adjusting block 152 and the adjusting groove 151 can all select the related technology of the existing electric sliding block and electric sliding groove, so that the sliding block 14 can automatically slide along the sliding groove 13, and the adjusting block 152 can also automatically slide along the adjusting groove 151 by the control of the control center.

[0073] Specific working process: on the basis of the specific working process in embodiment one, when the person to be measured stands on the positioning seat 2, the detection plates 16 on both sides are located on both sides of the person to be measured; during the measurement process, the sliding block 14 is controlled to move downward along the sliding groove 13, so that the sliding block 14 moves to the height of the person to be measured, and then the adjusting blocks 152 on both sides are controlled to move towards each other, so that the detection plates 16 approach the person to be measured from both sides; the detection plates 16 approach the clothing-shielded area below the neck of the person to be measured, and move downward at the same time, and scanning detection is performed;

[0074] The detection device on the detection plate 16 can select a metal detection device or an X-ray perspective scanning detection device to perform scanning detection on the clothing-shielded area of the person to be measured who approaches, and transmit the detection result to the display screen of the display interface 5, so that the safety management personnel can understand; compared with manual detection and investigation of dangerous goods, this automatic investigation method is more comprehensive and efficient, saves labor cost, improves the investigation accuracy, and further guarantees the safety of the public;

[0075] Further, the detection plate 16 can be further slid to approach the person to be measured during the downward movement, and contact and extrude the person to be measured, so that the action of the person to be measured can be corrected, the feature information of each part of the body of the person to be measured can be fully collected by the laser three-dimensional scanner 6, and the clothes of the person to be measured are extruded to be closer to the body, so that the data obtained after scanning and collection is more consistent with the real posture of the person to be measured, the error is reduced, and the body feature model of the person to be measured constructed by laser scanning is more accurate;

[0076] Through the cooperation of the positioning seat 2, the person to be measured can be driven to rotate, the detection plate 16 contacts and extrudes the person to be measured at different angles, so that the whole body of the person to be measured can be more comprehensively investigated, and the body feature of the person to be measured can be more comprehensively measured, so that more accurate results can be obtained;

[0077] And a pressure sensor can be arranged at the contact part between the detection plate 16 and the person to be measured, so as to detect the pressure in the contact and extrusion process, and when the pressure is too large to cause discomfort to the person to be measured, the control center can be fed back in time to stop the continuous sliding of the detection plate 16 and retreat a distance, so as to avoid complaints from the person to be measured.

[0078] Embodiment five:

[0081] Specific working process: on the basis of the specific working process in embodiment three, when the detection plate 16 slides transversely along the adjusting groove 151 and approaches the extruded person to be measured, the end of the positioning block 17 protruding from the surface of the detection plate 16 first contacts the person to be measured. Because the contact surface of the end of the positioning block 17 is small, the pressure on the clothing contact surface of the person to be measured is large, which further extrudes the clothing of the person to be measured, so that the clothing contact part of the person to be measured shrinks and is closer to the body of the person to be measured, the data obtained by laser scanning is more consistent with the true appearance of the person to be measured, and the accuracy of the measurement process is improved.

[0082] Further, in the projection measurement process, the positioning laser lamp 171 is arranged on the end of the positioning block 17. During the extrusion process, the laser light emitted by the positioning laser lamp 171 falls on the projection plate 3 to form a positioning light point. The position of the positioning light point is closer to the body contour of the person to be measured. During the detection process of the detection plate 16, the detection plate 16 will slide close to the person to be measured at intervals to extrude and contact the person to be measured. At the same time, the positioning laser lamp 171 will also be started to form a positioning light point on the projection. After the information collected by the camera 41 is collected, the detection plate 16 retreats, the measurement plate 15 drives the detection plate 16 to move downward by a distance, and then the above-mentioned actions are repeated.

[0083] In this way, a plurality of positioning light points are formed on the projection surface, and the projection figure formed by the mutual connection of the positioning light points is closer to the real body contour data of the person to be measured, effectively reducing the interference of the fluffy clothes on the body appearance data measurement of the person to be measured, and improving the measurement accuracy. The body appearance data measured in the database comparison process cooperates with the facial portrait information to provide multiple safeguards and further improves the accuracy of the investigation of dangerous persons.

[0084] Further, the detection plate 16 is provided with a plurality of measurement cameras 162, part of the measurement cameras 162 are directly opposite the person to be measured, and part of the measurement cameras 162 are directly opposite the projection plate 3. When the detection plate 16 contacts and presses the person to be measured, the measurement cameras 162 directly opposite the person to be measured can be close to the person to be measured to fully collect the details of the body and clothes of the person to be measured, thereby improving the measurement accuracy. At the same time, the measurement cameras 162 directly opposite the projection plate 3 can avoid the shielding of the body of the person to be measured because they are located on both sides of the person to be measured, thereby fully collecting the data of the projection plate 3. The measurement cameras 162 are started synchronously with the positioning laser lamp 171 to collect the projection data of the positioning light spot, thereby improving the measurement accuracy of the physical appearance data of the person to be measured.

[0085] Embodiment six:

[0086] On the basis of embodiment five, the end surface of the detection plate 16 is provided with a traction rope 18, the end of the traction rope 18 extends into the mounting groove 181 at the top of the monitoring and measuring channel 1, and the end of the traction rope 18 is wound on the pay-off roller 182 arranged inside the mounting groove 181. The rotating shaft arranged in the middle part of the pay-off roller 182 is connected with the driving device connected with the side wall of the mounting groove 181. The driving device here can be a driving motor, which is controlled by the control center.

[0087] Specific working process: on the basis of the specific working process in embodiment four, because the detection plate 16 is only fixed and limited on one side, it may cause instability of the measurement plate 15. Therefore, the traction rope 18 is arranged on the suspended end of the detection plate 16 on one side, and the suspended end of the detection plate 16 on one side is pulled to make both sides of the detection plate 16 be fixed and limited. During the downward movement, the driving device connected with the rotating shaft in the middle part of the pay-off roller 182 is started synchronously with the downward movement of the sliding block 14, so that the traction rope 18 is continuously paid out from the pay-off roller 182, and the control driving device is slowly moved downward. The traction rope 18 continuously maintains a tight state during the downward movement of the detection plate 16, so that the suspended end of the detection plate 16 on one side is subjected to an upward pulling force, thereby offsetting part of the stress on the connection part between the detection plate 16 and the positioning block 17 due to gravity, further reducing the load on the connection part between the detection plate 16 and the positioning block 17, and making the detection plate 16 more stable during operation.

[0088] Further, when the detection is completed and needs to be reset, the driving device is reversely moved to make the traction rope 18 be wound on the pay-off roller 182 again, and pull the detection plate 16 upward to make the force on both sides of the detection plate 16 balanced, thereby improving the service life.

[0089] Embodiment seven:

[0090] On the basis of embodiment six, the traction rope 18 is a tubular structure, and one end of the traction rope 18 is communicated with the air supply device installed on the side wall of the installation groove 181, and the other end extends into the inside of the extrusion groove 161, and the air supply device can adopt a micro air pump device; the end of the positioning block 17 is provided with a safety inductor, the end of the positioning block 17 is provided with a cleaning hole 172 communicated with the inside of the extrusion groove 161; the side wall of the positioning block 17 is uniformly provided with a flow guide hole 173 communicated with the middle part of the cleaning hole 172, and the opening of the flow guide hole 173 points to the part of the surface of the detection plate 16 between the extrusion grooves 161.

[0091] Specific working process: on the basis of the specific working process in embodiment six, in the direct contact process, the surface of the detection plate 16 and the end of the positioning block 17 contact the human body, especially the clothes and the skin surface of the human body, and may adhere to sweat stains and impurities such as clothes fibers, which have not been cleaned in time, and may cause bacterial proliferation and even infection accidents; therefore, the traction rope 18 is arranged in a tubular structure, and a metal hose structure can be adopted, so that the shape can be better maintained even in the entangled state, and excessive deformation that causes airflow to be unable to pass through and further causes a blocked condition is avoided.

[0092] After starting the air supply device, the airflow can flow into the inside of the traction rope 18 through the air supply device, then flow into the extrusion groove 161, and then flow into the inside of the positioning block 17 through the inlet of the cleaning hole 172 in the inside of the extrusion groove 161, and then flow out from the outlet on the surface of the end of the positioning block 17; in this process, because the opening of the cleaning hole 172 is in a horn shape, the action range of the dry airflow after flowing out is large, and the airflow speed near the surface of the end of the positioning block 17 is effectively accelerated, so that the impurities on the surface of the end of the positioning block 17 are cleaned;

[0093] And the flow guide hole 173 is arranged on the side wall of the positioning block 17, so that part of the airflow in the cleaning hole 172 flows out from the flow guide hole 173, and at the same time, the flow guide hole 173 flushes the gap part of the surface of the detection plate 16 between the positioning blocks 17, so that the impurities adhered to the surface of the detection plate 16 are effectively cleaned, and the normal work of the related detection end of the detection device is ensured; the flow of the airflow makes the surface of the positioning block 17 and the detection plate 16 dry, destroys the bacterial breeding environment, and prevents the breeding and infection of bacteria;

[0094] Further, the air inlet of the air supply device can be communicated with an existing disinfectant gas supply device, and the disinfectant gas contains disinfectant and sterilization components such as alcohol, which can effectively disinfect the surface of the positioning block 17 and the detection plate 16 through the airflow, ensure the safety of the measured person in the measurement process, and reduce the workload of manual cleaning.
