[0024] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0025] See also Figure 1 , Figure 1 The figure is a schematic perspective view of the structure of a spectacle frame provided by an embodiment of the present invention. The spectacle frame comprises a frame 1, temples 2, and a positioning assembly, wherein the positioning assembly comprises a pendulum 4, a reference plate 6, a first reference point 5, and a second reference point 9. The temples 2 are two and are rotatably connected to either side of the frame 1. The pendulum 4 is suspended from the frame 1. The reference plate 6 is fixed to the frame 1 and is perpendicular to the frame 1. The first reference points 5 are all fixed to the frame 1, and the second reference points 9 are fixed to the temples 2.

[0026] By setting a positioning component on the glasses frame, that is, fixing the reference point, reference plate 6, and pendulum 4 on the frame 1, and fixing the second reference point 9 on the temple 2, the glasses frame 1 can be worn on the head of the person being measured when the head size is measured. Then, the person being measured wearing the glasses frame of the utility model is photographed, and the pupil distance of the person being measured is measured under the reference positioning of the first reference point 5, that is, the distance between the two pupils of the person being measured is measured from the front, so that the staff can configure the corresponding lenses for the person being measured according to the measured pupil distance. Similarly, the nose-to-ear distance of the person being measured is measured under the reference positioning of the second reference point 9, that is, the distance between the nose bridge and the ear of the person being measured is measured from the side, so that the staff can make the corresponding temple 2 for the person being measured according to the measured nose-to-ear distance.

[0027] When photographing a person wearing a pair of glasses, the person's head posture may change, which may cause the angle of the frame 1 or the temple 2 to change, and ultimately lead to errors in the measured pupil distance or nose-to-ear distance. Therefore, before photographing the person, the frame 1 is first positioned through the first reference point 5, and vertical information is obtained under the action of the pendulum 4, so that the staff can calculate the deflection angle of the frame 1 relative to the pendulum 4 based on the vertical information, so as to calculate the pupil distance of the person after correcting the deflection angle of the frame 1, thereby improving the accuracy of the pupil distance calculation.

[0028] In the above embodiment, the deflection angle of the head of the person being measured relative to the camera, that is, the deflection angle of the frame 1, is determined by the reference piece 6 fixed on the frame 1. When the head of the person being measured does not generate a deflection angle relative to the camera, the reference piece 6 will project a straight line on the frame 1, so that the staff can determine whether the frame 1 generates a deflection angle based on the straight line projected by the reference piece 6. When the head of the person being measured has a deflection angle relative to the camera, the reference piece 6 will project a coverage area on the frame 1, and then the deflection angle of the frame 1 is obtained by calculating the length of the coverage area, so that the staff can decide whether the head angle of the person being measured needs to be adjusted based on the deflection angle.

[0029] By wearing the glasses frame of the present invention on the head of the person being measured, the front and side of the person being measured can be photographed and positioned according to the first reference point 5 and the second reference point 9 respectively. When photographing the front of the person being measured, the deflection angle of the frame 1 relative to the pendulum member 4 can be obtained through the pendulum member 4, and the deflection angle of the frame 1 can be obtained through the reference piece 6. Then, when calculating the pupil distance size, the pupil distance size can be corrected in combination with the deflection angle to ensure that the calculated pupil distance is more suitable for the person being measured. The nose-to-ear distance of the person being measured is calculated under the positioning of the second reference point 9, so that the staff can make the length of the temple 2 that is more suitable for the person being measured for the person being measured, thereby improving the accuracy of the person being measured when taking a photo of the glasses frame and the anti-interference ability of the head posture, and preventing the change of the head posture of the person being measured from affecting the accuracy of the final measurement data.

[0030] In the embodiment of the present invention, the pendulum member 4 includes a wire body and a vertical body, and the vertical body is suspended on the frame 1 through the wire body.

[0031] See also Figure 2 By fixing the wire body on the frame 1 and the pituitary gland on the wire body, the pituitary gland can be kept in a vertical downward position under the connection of the wire body after the person being tested wears the glasses frame. Then, the angle between the wire body and the frame 1 can be used to determine whether the person being tested's head is deflected. When the angle between the wire body and the frame 1 is not equal to 90°, it means that the person being tested's head is deflected. Figure 2 As shown, when the head of the person being measured is deflected to the lower left, it can be determined by calculating the angle between the line and the frame 1 that the head of the person being measured is deflected to the lower left.

[0032] In the above embodiment, there are two pendant members 4, which are fixed to the left and right sides of the frame 1 respectively. Figure 2 As shown, when the head of the person being measured is deflected to the lower left, the angle between the line on the left and the frame 1 is calculated to be greater than 90°, and the angle between the line on the right and the frame 1 is less than 90°, thereby determining that the head of the person being measured is deflected to the lower left.

[0033] In an embodiment of the present utility model, the wire body includes any one of a limiting wire body, a rubber wire body, and a metal wire body, so that the pituitary body is fixed on the wire body and suspended on the frame 1 through the wire body, so that the staff can judge whether the head of the person being measured is deflected and the direction and angle of the deflection according to the angle between the wire body and the frame 1. The pituitary body includes any one of a plastic pituitary body, a rubber pituitary body, and a metal pituitary body, so that the pituitary body is suspended on the frame 1 and can always maintain a vertical downward state, and the wire body forms a reference line in the vertical direction.

[0034] In an embodiment of the present utility model, a nose pad 3 is provided in the middle of the frame 1, and the number of the first reference points 5 is at least two, preferably, the number of the first reference points 5 is three, wherein the two first reference points 5 are symmetrically fixed at the two sides of the frame 1, and one first reference point 5 is fixed above the nose pad 3, so that when the worker takes a photo of the person being measured, the front of the person being measured is photographed and positioned through the three first reference points 5, so as to ensure that the person being measured maintains a straight-facing state relative to the front, reduce the deflection of the head posture of the person being measured, and improve the measurement accuracy of the pupil distance of the person being measured.

[0035] In an embodiment of the present invention, a first scale line 7 is provided at a position corresponding to the reference piece 6 of the frame 1. The first scale line 7, the first reference point 5 and the reference piece 6 are all located on the same surface of the frame 1, and the reference piece 6 is aligned with the first scale line 7.

[0036] By setting the first scale line 7, the first reference point 5 and the reference piece 6 on the same surface of the frame 1, the frame 1 can be photographed and positioned under the action of the first reference point 5, and the length of the coverage area of ​​the reference piece 6 can be measured under the action of the first scale line 7. That is, when the head of the person being measured is deflected relative to the camera, the reference piece 6 will form a coverage area on the first scale line 7, and then by reading the scale value of the coverage area on the first scale line 7 and calculating the deflection angle of the frame 1 according to the scale value, the staff can decide whether it is necessary to adjust the head angle of the person being measured according to the deflection angle.

[0037] In an embodiment of the present invention, the number of second reference points 9 is at least two. Preferably, the number of second reference points 9 is two, and the two second reference points 9 are both located on the outside of the same temple 2, so that when the staff takes a photo of the side of the person being measured, the temple 2 can be positioned by taking a photo through the two second reference points 9.

[0038] In the embodiment of the present invention, a second scale line 8 is provided on the outer side of the temple 2 , and the second scale line 8 and the second reference point 9 are located on the same surface of the temple 2 .

[0039] By setting a second scale line 8 on the outside of the temple 2 and making the second scale line 8 and the second reference point 9 located on the same surface of the temple 2, after taking a side photo of the person being measured, the scale value can be directly read through the second scale line 8 to obtain the length of the temple 2 that best suits the person being measured.

[0040] In an embodiment of the present invention, the first reference point 5 includes any one of a pure color reference point, a color reference point, and a black and white reference point; the second reference point 9 includes any one of a pure color reference point, a color reference point, and a black and white reference point.

[0041] By setting the first reference point 5 and the second reference point 9 to solid color, color, and black and white, when taking a photo of the frame 1 and the temple 2, the frame 1 is positioned by the first reference point 5, and the temple 2 is positioned by the second reference point 9, thereby improving the positioning speed and accuracy of the frame 1 and the temple 2.

[0042] In an embodiment of the present invention, the first reference point 5 includes a black and white reference point, and the second reference point 9 is a black and white reference point. The black and white reference points are filled with black and white using a cross-circular pattern.

[0043] By setting the first reference point 5 and the second reference point 9 as black and white reference points, the black and white reference points are filled with black and white using a cross-circular pattern, so that the obvious contrast between black and white can be used to position the frame 1 and the temple 2. At the same time, the cross line is also conducive to the selection of positioning points during positioning.

[0044] See also Figure 2 When calculating the pupillary distance L1 of the person being measured, a camera is used to photograph the front of the person being measured, and then the distance data L2 between the eyes of the person being measured is measured using image measurement software. The distance data L3 between the first reference points 5 on both sides of the frame 1 is also measured using image measurement software. Combined with the actual distance data L4 between the first reference points 5 on both sides of the frame 1, formula 1 is used to calculate the pupillary distance of the person being measured, where formula 1 is:

[0045] L1=(L2*L4) / L3

[0046] See also Figure 3 If the photo is vertically deflected, you can measure Figure 3 If the angles of θ1 and θ2 are equal, it means that the head angle of the person being measured has not changed. When measuring the data, you can only correct the photo angle for measurement. If the angles of θ1 and θ2 are inconsistent, it means that the angle with the larger angle has tilted upward. Since the temple 2 is placed on the ear, it does not slide down. At this time, correct the photo angle according to the angle with the smaller angle. Assuming that θ2>θ1, use Formula 2 to calculate the corrected pupil distance of the person being measured, where Formula 2 is:

[0047] L1=(L2*L4 / L3) / COS(θ2-θ1),

[0048] See also Figure 4 ,exist Figure 4In the image, the reference sheet 6 covers part of the first scale line 7. This indicates that the head of the person being measured has deflected in the horizontal direction. The size of the covered area is read according to the first scale line 7 and recorded as LA. In this image, LA has two sizes, one of which is the actual scale value measured by the first scale line 7, and the other is the software scale value measured using the software in the image, recorded as LA. 刻度 and LA 软件 , then the horizontal deflection angle = arcCOS(LA 软件 / LA 刻度 ), at this time, the horizontal dimensions of the measured person's face are still in proportional relationship, and the calculation using formula 1 is still accurate data.

[0049] See also Figure 5 When taking a photo and measuring the side of the person being measured, the distance from the frame 1 to the contact point on the upper part of the ear can be directly read through the scale value of the second scale line 8, and the head posture state can be measured by software using the angle between the vertical edge of the frame 1 and the pendulum 4, thereby improving the scale accuracy measured by the second scale line 8, so that the staff can make the temples 2 of the corresponding length according to the scale value.
