[0022] The present invention is further described below in conjunction with the accompanying drawings.

[0023] according to Figure 1-5 As shown: The present invention provides a rotatable chair for assisting facial photography: it comprises a shooting room 1, in which a fixed bracket 4 is fixedly arranged; a camera 3 is arranged above the fixed bracket 4, and a high-back chair 8 is arranged on one side of the camera 3; a light source 2 is arranged on the inner wall of the shooting room 1 on both sides of the camera 3, and a background cloth 26 of black light-absorbing material is arranged behind the high-back chair 8 and located on the inner wall of the shooting room 1; a fixed column 12 is fixedly connected to the fixed bracket 4, and the camera 3 is fixedly arranged on the fixed column 12; a fixed plate 7 is fixedly arranged in the shooting room 1, a groove 10 is provided in the fixed plate 7, and a rotating block 9 is rotatably arranged in the groove 10; a lifting structure is arranged on the rotating block 9, and the lifting structure is fixedly connected to the high-back chair 8; a limited position plug hole 14 is provided on the fixed plate 7, and a plug-in structure is slidably arranged on one side of the rotating block 9, and the plug-in structure is inserted into the plug hole; a mirror 6 is arranged between the fixed bracket 4 and the fixed plate 7, and an auxiliary alignment structure is arranged on the mirror 6.

[0024] By using a fixed light source 2 and a black background cloth 26, the lighting conditions can be controlled to obtain high-quality images; by setting a plug-in structure, the high-back chair 8 can be fixed using the limiting socket 14, thereby ensuring that the high-back chair 8 is always at a fixed angle after rotation; and by setting a mirror 6 and an auxiliary alignment structure, the subject can be helped to assume the correct posture.

[0025] like Figure 3As shown, a support plate 5 is placed in the shooting room 1, a slide groove 11 is provided in the support plate 5, and a mirror 6 is slidably arranged in the slide groove 11. An electric telescopic rod 13 is arranged in the slide groove 11, and the working end of the electric telescopic rod 13 is fixedly connected to the mirror 6. By setting the electric telescopic rod 13, the mirror 6 can be driven to rise and fall. After the mirror 6 is used, the mirror 6 can be moved downward for a distance to prevent the mirror 6 from blocking the camera head of the camera 3.

[0026] like Figure 4 , 5 As shown, the lifting structure includes a hydraulic rod 15, which is arranged in the rotating block 9, and the working end of the hydraulic rod 15 is fixedly connected to the high back chair 8. The plug-in structure includes a limit plate 27, a connecting rod 19, a connecting plate 18, and an insert rod 17; a guide groove 22 is provided in the rotating block 9, and the limit plate 27 is slidably arranged in the guide groove 22; a limit groove 16 connected to the guide groove 22 is provided on the side wall of the rotating block 9, and the connecting rod 19 is located in the limit groove 16; the connecting plate 18 is arranged on the outer wall of the rotating block 9, and the connecting plate 18 is fixedly connected to the limit plate 27 through the connecting rod 19; the insert rod 17 is fixedly connected to the bottom of the connecting plate 18, and the insert rod 17 is inserted into the limit plug hole 14. A pull rod 20 fixedly connected to the limit plate 27 is provided in the guide groove 22; a spring 21 sleeved on the pull rod 20 is provided in the guide groove 22, and the spring 21 is located above the limit plate 27. There are five limit holes 14 . With respect to the camera 3 , one of the limit holes 14 is located in a direction facing the camera 3 , and the other four limit holes 14 indicate directions of 45° to the left and right and 90° to the left and right, respectively.

[0027] A synchronization rod 23 is fixedly connected to the fixed plate 7, and the synchronization rod 23 is fixedly connected to the support plate 5; by setting the synchronization rod 23, when the rotating block 9 rotates, the support plate 5 can be driven to rotate synchronously through the synchronization rod 23, so as to always keep the mirror 6 aligned with the subject. The auxiliary alignment structure includes a vertical marking line 24 and a horizontal marking line 25, the vertical marking line 24 is located in the middle of the mirror 6, and the horizontal marking line 25 is 100 cm above the ground. By setting two marking lines, the subject can be helped to put on the correct posture and improve the shooting effect.

[0028] The core principle of using auxiliary alignment structure is: the range of head movement is mainly

[0029] 1. Tilt forward and backward (nod and tilt head back): The human head can tilt forward about 45 degrees and tilt backward about 60 degrees.

[0030] 2. Left and right rotation: The head can rotate about 70-90 degrees left and right.

[0031] 3. Lateral tilt (ears towards shoulders): The head can tilt about 40 degrees to the left or right.

[0032] The direction of a person's head movement can be described by the XYZ axis. As long as the movement in these three directions is fixed, the angle of the facial photo can remain consistent. The direction of nodding and tilting the head can be fixed by a high backrest, that is, the Y axis is fixed; the patient aligns the line between the eyes and the line between the brow and the philtrum on the opposite mirror to fix the X axis and Z axis. At the same time, through the height-adjustable chair, each patient's face is roughly at the same height, so that a fixed camera position can be used to reduce the bias and error caused by inconsistent camera positions each time.

[0033] Principle of the Invention

[0034] like Figure 1-2 As shown, the shooting room 1 is set up: there is no other natural light source 2 in the room, and the light source 2 located on both sides of the camera 3 is used to provide illumination; the background cloth 26 is made of black light-absorbing material. Camera 3 setting: The camera 3 is set at a distance of about 80 cm from the subject's face.

[0035] like Figure 4 As shown, the high-back chair 8 is set up: the subject sits on the high-back chair 8 which can rotate and rise and fall, and the eye height is adjusted to about 100 cm by the hydraulic rod 15. The back of the chair is very high, and the subject's buttocks and back of the head are required to lean against the back of the chair. After the subject sits on the high-back chair 8, as shown in FIG. Figure 3 As shown, the vertical marking line 24 and the horizontal marking line 25 on the mirror 6 are used to put the user in the correct posture to avoid tilting. After adjusting the posture, the electric telescopic rod 13 can be used to drive the mirror 6 to move downward to avoid the mirror 6 blocking the camera 3 during shooting; Figure 4 , 5 As shown, after the frontal shooting is completed, the subject remains motionless, and the assistant pulls the pull rod 20 to pull the connecting plate 18 and the insertion rod 17 upward, so that the insertion rod 17 is disengaged from the limiting socket 14, and the limiting plate 27 compresses the spring 21; the rotating block 9 is rotated to drive the high-back chair 8 and the subject to rotate together. When the insertion rod 17 is rotated to the position of the limiting socket 14 corresponding to 45° or 90°, the pull rod 20 is released. Under the action of the rebound force of the spring 21, the connecting plate 18 drives the insertion rod 17 to move downward and insert it into the limiting socket 14, which can ensure the accuracy of the rotation angle. At the same time, when the rotating block 9 rotates, the support plate 5 can be driven to rotate synchronously through the synchronization rod 23, so that the mirror 6 is always aligned with the subject. Therefore, the present application effectively reduces the deviation of angle and position during shooting, and improves the consistency and comparability of photos.

[0036] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
