Description

Technical Field

[0001] The invention belongs to the technical field of scalp hair loss detection, and in particular relates to a three-dimensional analysis device for hair loss areas based on hemispherical multi-view image acquisition. Background Art

[0002] The three-spectrum scalp detection uses standard white light, cross-polarized light, and UV light to observe the surface layer, dermis, and subcutaneous tissue of the scalp through physical imaging technology. The control system controls the lighting system to select different spectra. After amplification and filtering by the optical system, the light signal is received by the image acquisition chip and converted into a digital photoelectric signal by the image acquisition chip. The photoelectric signal is transmitted to the DSP processor for further processing and encoding to form a standard USB signal required by the host computer. The USB signal is transmitted to the computer through the USB interface and received by the software system. Through calculation, decoding, and data processing, a real-time video image is formed.

[0003] By magnifying the local scalp, you can observe the scalp texture, the distribution characteristics of the skin grooves and ridges, the metabolism of keratin, the oiliness of the scalp, and compare and identify the characteristics of various scalp diseases. You can also magnify the local hair to observe the growth and distribution characteristics of the hair, the density and diameter of the hair, etc.; it is used to observe the local inflammation of the dermis of the scalp, the expansion of capillaries, the blood exudation, the distribution pattern and growth and decline, and whether the skin is normal, sensitive or red after using skin care products.

[0004] Traditional scalp photography tools require manual adjustment of angles, making it difficult to obtain full scalp images at one time, and there is a risk of missed detection. When the patient's head moves or the lighting is uneven, the image is easily blurred and the quality is uneven, affecting the accuracy of hair loss area calculation. Doctors need to manually take multiple photos and synthesize them into 3D models, which is time-consuming and dependent on operating experience, resulting in reduced photography efficiency. At the same time, due to the differences in body shape among patients, it is difficult to adjust the height of the acquisition equipment according to their condition, which greatly affects the scope of use of the acquisition equipment.

When the adjusting screw rod 603 rotates, it can cooperate with the lifting rod 6 through the connecting screw hole 601, so that the lifting rod 6 can slide up and down to adjust the height of the ball shell 1 according to the height of the bed surface. Four groups of limiting slide grooves 602 are evenly opened on the outside of the lifting rod 6, and the protrusions in the limiting slide cylinder 702 slide along the inside of the limiting slide groove 602, and the set limiting slide cylinder 702 cooperates with the limiting slide groove 602, so that The lifting rod 6 can be limited to avoid the lifting rod 6 from deflecting and shaking; the upper end surface of the base member 7 is fixed with a connecting cylinder 701, and the substrate member 607 is fixed to the connecting cylinder 701, and the upper end surface of the connecting cylinder 701 is fixed with a limiting slide cylinder 702. The connecting cylinder 701 can limit and support the substrate member 607 to avoid the substrate member 607 from deflecting. Then, the substrate member 607 can avoid the shaking of the adjusting screw rod 603 and affect the subsequent processing.

[0043] Working principle: This application document should be noted before use. The ball shell 1 is composed of a frame member 101 and an acrylic shell 102, which can make the ball shell 1 more lightweight. At the same time, the ball shell 1 has a curvature radius of 50 cm, which is suitable for the head circumference of an adult. In addition, the extension member 2 is an arc-shaped structure and extends to one side, which is convenient for patients to use. At the same time, because the side of the extension member 2 is an arc-shaped structure, it may bump against the patient and affect subsequent treatment. The control middle end 301 is set to control the electronic components inside the air pump member 204, the shooting component 4 and the base member 7, so as to facilitate subsequent adjustment. The heat dissipation port 302 is set to allow the gas to circulate normally, which not only facilitates the subsequent normal air intake of the air pump member 204, but also dissipates the heat of the control middle end 301 during air intake, and also facilitates subsequent treatment.

[0044] When in use, the patient is comforted to lie flat on the bed, and the position of the device can be adjusted through the universal wheel 703 at the lower end of the base member 7. Then, the position of the support frame 802 can be adjusted through the provided lifting motor 801. When the support frame 802 descends, the anti-slip groove 803 at the lower end of the support frame 802 can contact the ground, which can ensure the stability of the base member 7. Then the servo motor 606 is turned on, and the servo motor 606 is set to drive the connecting gear 605 to rotate. When the connecting gear 605 rotates, it can drive the adjusting gear 604 to rotate accordingly. Since the adjusting screw rod 603 can By being rotatably connected with the base plate 607, the adjusting screw rod 603 can rotate more smoothly. When the adjusting screw rod 603 rotates, it can cooperate with the lifting rod 6 through the connecting screw hole 601, so that the lifting rod 6 can slide up and down to adjust, so that the height of the ball shell 1 can be adjusted according to the height of the bed surface. Four groups of limiting slide grooves 602 are evenly opened on the outside of the lifting rod 6, and the protrusions in the limiting slide cylinder 702 slide along the inside of the limiting slide groove 602. The setting of the limiting slide cylinder 702 cooperates with the limiting slide groove 602 to limit the lifting rod 6, which can prevent the lifting rod 6 from deflecting and shaking.

[0045] Then, the patient's head is assisted to be placed inside the ball shell 1, and is in contact with the patient's lower jaw through the lower jaw support component 201. The lower jaw support component 201 is made of rubber material, which can avoid discomfort to the patient during use, and the inclined groove 203 on the upper end surface of the lower jaw support component 201 is an arc-shaped structure, which can make the patient feel more comfortable, and the laser focusing component can focus on the patient's head. Then, the air pump component 204 is turned on, and the air pump component 204 can supply air to the connecting conduit 205, so that the gas can be guided to The air pump part 204 is connected to the air bag part 202 through the connecting conduit 205, so that the height of the lower jaw support part 201 can be adjusted, so that the position of the patient's head can be adjusted according to the height and body shape of the patient, and the position of the fixing frame 502 can be supported by the provided connecting rod 501. When the position of the fixing frame 502 is adjusted, its surface can be in contact with the patient's forehead to avoid the patient's forehead from being deviated. Then, the provided silicone pad 503 can be in contact with the patient's forehead to make the patient feel comfortable.

[0046] Finally, by turning on the shooting component 4 through the control terminal 301, multiple groups of shooting components 4 can be triggered synchronously to ensure the consistency of image time, and transmit data to the computer terminal through the wired network to facilitate medical staff to observe and record. The shooting component 4 is set up to include a visible light camera, a near-infrared camera and a ring-shaped LED array. The visible light camera has 20 million pixels and is used for surface morphology shooting. The near-infrared camera can detect the activity of subcutaneous hair follicles, and the light of the ring-shaped LED array can provide a uniform cold light source with a fixed brightness temperature. The laser projects a cross reference line to assist in positioning and detecting whether the head is in the focus of the camera. Finally, the laser focusing component is installed in the center of the top of the spherical shell 1, and a cross laser line is projected downward to calibrate the center position of the patient's head. When the laser focusing component detects a deviation in the position of the top of the head (such as a difference in the height of the patient), it can be adjusted through the air supply adjustment mechanism.
