Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and particularly to a hair detection device and a hair detection method. Background Art
[0002] As a branch in a refined field of dermoscopes, a trichoscope is specifically used for detecting scalp conditions, such as the number of hair follicles, hair thickness, scalp inflammation, dandruff conditions, etc. It is often used in the fields of hair growth or hair transplantation for the condition assessment before treatment and the tracking of the scalp hair state after treatment.
[0003] For an ordinary trichoscope, the field of view angle and the field of view range are fixed. When doctors and patients use it, they need to part the hair to expose the scalp area, align this area to capture pictures, and then analyze and judge the information in the pictures, such as calculating the number of hair follicles and detecting hair thickness. However, if the trichoscope is not operated properly, some hair follicles in the captured pictures are blocked by hair, or there is mutual occlusion between hairs, which will lead to incorrect calculation of information and misjudgment by doctors. As Figure 1 shown, the red circle area is the scalp area blocked by hair. If the shooting method is repeatedly adjusted to achieve the best picture effect, it will prolong the working time of medical staff and reduce work efficiency.
[0004] To solve this problem, the existing solution is to shave off the patient's hair before taking pictures for diagnosis, leaving only a small part of the root area. As Figure 2 shown, although the problem of hair blockage no longer exists after shaving the hair, the capture of pictures becomes extremely simple, and the calculation pressure of scalp information will also be reduced. However, shaving the patient's hair will seriously affect the physical and mental health of the patient and increase the psychological pressure of the patient, especially it is not applicable to female patients. And the shaving method is not practical in various usage scenarios. For example, when a patient needs to undergo long-term detection, it is impossible to require shaving at each detection; and when a patient only undergoes a routine detection and just wants to simply check the hair follicle distribution density, shaving is unacceptable. Summary of the Invention
[0005] The purpose of the present invention is to provide a hair detection device and a hair detection method, which improve the accuracy of image recognition, thereby improving the accuracy of doctors' diagnosis, and also improving the efficiency of collecting scalp images.
[0006] To achieve the above purpose, in the first aspect, the present invention provides a hair detection device, including a controller, a rotating bracket, and a trichoscope; The controller is connected to the rotating bracket and is used to control the movement of the rotating bracket; The rotating bracket has a movable part, and the trichoscope is arranged on the movable part and can move along with the movable part. The trichoscope is used to collect information data of the scalp area; When performing hair detection, the controller controls the movement of the rotating bracket so that the hairscope can collect information data of the scalp area at different angles to obtain an information data set. The beneficial effect of the hair detection device provided by the present invention is that: by controlling the movement of the rotating bracket by the controller, the hairscope can be driven to collect information data of the scalp area at different angles to obtain an information data set, which improves the accuracy of image recognition, avoids hair blocking the scalp area, thereby improving the accuracy of doctor diagnosis, and also improves the efficiency of collecting scalp images.
[0007] In some embodiments, based on the initial position of the hairscope, the rotating bracket can drive the hairscope to rotate at an angle of -30° to 30°. The beneficial effect is that: by controlling the rotation angle of the hairscope by the rotating bracket within -30° to 30°, it is avoided that defocus occurs within the field of view of the hairscope, or the field of view of the lens of the hairscope exceeds the field of view range.
[0008] In some embodiments, the controller is provided with a first control program and a second control program; The first control program is used to control the rotating bracket to drive the hairscope to rotate along the hair parting direction, and every time it rotates 1° to 3°, it controls the hairscope to collect information data of the scalp area once; The second control program is used to control the rotating bracket to drive the hairscope to rotate along the direction perpendicular to the hair parting, and every time it rotates 1° to 3°, it controls the hairscope to collect information data of the scalp area once. The beneficial effect is that: by setting the first control program and the second control program on the controller, there are at least panoramic photos in at least two directions during hair detection. Therefore, no matter in which direction the hair produces occlusion, there will be a photo at another side angle to capture the scalp area of the occluded part. In this way, through the superposition of photos at different angles, information data of all hair follicles and hairs on the scalp area can be obtained. Finally, the information data is uploaded to the algorithm software for analysis.

Refer to Figures 1 to 6 As shown, this detection method uses the hair detection device 100 mentioned in the above embodiment for detection, and the method includes: S601: The controller 3 controls the movement of the rotating bracket 4 so that the hair mirror 8 faces the scalp area to be detected.
[0033] In this step, specifically, the controller 3 controls the movement of the rotating bracket 4 to transfer the hair mirror 8 to the initial position and make the hair mirror 8 face the scalp area to be detected. Among them, this initial position is set as the reference.
