Description

Technical Field

[0039] Infrared imaging detection often requires imaging detection of the subject's body from multiple angles. When the subject moves, their body temperature can change, causing the infrared imaging to capture infrared radiation generated by the subject's movement. This can interfere with the assessment of the subject's health status through infrared imaging. Therefore, how to reduce or avoid the movement of the subject during infrared detection is a technical problem that needs to be solved.

[0040] This utility model proposes an infrared imaging device.

[0041] Please see Figure 1 In one embodiment of this utility model, the infrared imaging device 100 includes: a frame assembly 1, an infrared camera 2, and a display device 3. The frame assembly 1 has a platform 12, and the upper part of the platform 12 is a detection area for a patient to stand in. The infrared camera 2 is connected to the frame assembly 1 and is positioned facing the detection area. The infrared camera 2 has a circumferential rotational range relative to the platform 12. The display device 3 is electrically connected to the infrared camera 2.

[0042] In this invention, the person being tested stands on platform 12. The relative rotation between platform 12 and infrared camera 2 enables multi-angle imaging detection of the human body, avoiding the generation of additional heat from movement by the person being tested, thus ensuring accurate detection. In the first embodiment, infrared camera 2 remains fixed while platform 12 rotates; in the second embodiment, platform 12 remains fixed while infrared camera 2 rotates around platform 12.

[0043] In the first embodiment, the frame assembly 1 further includes a main body 11, which serves as a frame for the installation and connection of various parts. A platform 12 is rotatably mounted on the main body 11 along its vertical axis. An infrared camera 2 is mounted on the main body 11 and located on one side of the platform 12 in the left-right direction. The rotation of the platform 12 can rotate the subject being measured, avoiding the subject having to move. This arrangement eliminates the need for the infrared camera 2 to move, thus reducing the volume of the main body 11 and saving on the overall size of the device. In this embodiment, the infrared camera 2 is fixed. For a single infrared camera 2, if it needs to capture the entire human body, it needs to be positioned relatively far from the platform 12. As the measurement distance increases, the temperature measurement will experience varying degrees of attenuation, so the measurement accuracy decreases with greater distance. This arrangement is necessary for a comprehensive measurement of the human body and to ensure measurement accuracy.

[0044] One type of setup method is as follows: Please refer to [link / reference]. Figure 2 Multiple infrared cameras 2 are provided, and the multiple infrared cameras 2 are spaced apart along the vertical direction on the main body 11. This arrangement can detect different height positions of the human body at the same time.

[0045] Another configuration involves the infrared camera 2 sliding vertically onto the main body 11. This configuration uses fewer infrared cameras, saving costs. The sliding mechanism can be a motor-driven gear mechanism, with the gear engaging a rack and pinion, and the rack connected to the infrared camera 2; alternatively, it can be a motor-driven lead screw and slider mechanism, where the connection between the slider and the infrared camera 2 is not limited, as long as the functionality is met.

[0046] In the second type of embodiment, please refer to Figure 3 The frame assembly 1 includes a main body 11, and the platform 12 is fixedly installed on the main body 11. The infrared camera 2 is installed on the main body 11 and located on one side of the platform 12, and has a range of motion that rotates around the platform 12 in a vertical direction. This arrangement allows the infrared camera 2 to rotate around the platform 12 (the subject being monitored), avoiding dizziness for the subject and preventing the airflow caused by the body's rotation from affecting heat and thus the imaging effect.

[0047] To enable the infrared camera 2 to rotate around the platform 12 (the object being monitored), the main body 11 includes a slide rail 13, which is arranged in a ring shape, and the platform 12 is arranged inside the slide rail 13. The frame assembly 1 also includes a sleeve 14, two roller groups 15, and a first motor. The sleeve 14 has an installation channel extending along its extension direction (the axis of the installation channel is arc-shaped). The sleeve 14 is fitted onto the slide rail 13, and an installation groove 141 is opened on the outer side of the sleeve 14. The two roller groups 15 are installed at intervals along the axial direction of the installation channel on the sleeve 14. The roller groups 15 include multiple rollers 151, which are installed at intervals along the circumferential direction of the installation channel on the sleeve 14, and at least partially located in the installation channel for abutting against the slide rail 13. The first motor is driven by at least one of the rollers 151. The roller 151 connected to the first motor is the driving wheel, and the others are driven wheels. The multiple rollers 151 ensure that the sleeve 14 runs smoothly along the slide rail 13.

[0048] To achieve a comprehensive measurement of the human body and ensure measurement accuracy, in this embodiment, the slide rail 13 of the main body 11 can be movably positioned in the vertical direction; the infrared camera 2 can also be tilted. Specifically, the sleeve 14 has a mounting groove 141 on its outer side. The frame assembly 1 includes a rotating component 16 and a second motor. The rotating component 16 is rotatably mounted in the mounting groove 141 along the tangential direction of the mounting channel axis, and at least partially protrudes from the mounting groove 141. The second motor is disposed in the mounting groove 141 and is drivenly connected to the rotating component 16. The infrared camera 2 is fixedly connected to the portion of the rotating component 16 that protrudes from the mounting groove 141. The second motor drives the rotating component 16 to rotate, thereby causing the infrared camera 2 to tilt.

[0049] Because the distance between the lens and the human body changes when the infrared camera 2 tilts, the infrared camera 2 needs to adjust its focus accordingly. The infrared imaging device 100 also includes a distance sensor 4 and a control device. The distance sensor 4 is fixedly mounted on the infrared camera 2 and faces the detection area; the control device is electrically connected to both the infrared camera 2 and the distance sensor 4. The distance sensor 4 detects the distance to the human body as the distance between the lens and the human body, and this distance value is transmitted to the control device, which then adjusts the focus of the infrared camera 2.

[0050] To ensure imaging accuracy, the infrared imaging device 100 also includes a contact temperature sensor 5 and a control device, the control device being electrically connected to the contact temperature sensor 5. The contact temperature sensor 5 detects the temperature value of a localized area on the subject's body and compares it with the initial image obtained from the infrared camera 2 to determine the accuracy of the temperature value displayed in the infrared image. If inaccurate, correction is performed using the display's built-in software.

[0051] To prevent external infrared radiation from interfering with the imaging, the infrared imaging device 100 also includes a baffle plate, which surrounds the outer periphery of the frame assembly 1 to isolate external heat sources.

[0052] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
