As shown in FIGS. 5 and 6 , an embodiment of the present invention further provides a calibration method for an augmented reality glasses device for calibrating the augmented reality glasses device shown in FIGS. 1 and 2 . First, a first bright line L1 (Fig. 5) can be projected at a first left limit position within the projection range of the optical engine of the left lens 12. At this time, since the first bright line L1 is It is located outside the field of vision of the user's left eye E1, so the pupils of the user's left and right eyes E1 and E2 will not be affected by the light of the first bright line L1 and shrink.

However, when the first bright line L1 moves a distance to the right from the first left limit position shown in FIG. 5 and enters the field of view of the user’s left eye E1 ( FIG. 6 ), the user’s left eye E1 The pupil of the user will be reduced by the light of the first bright line L1, and the pupil of the user's right eye E2 will also be reduced accordingly.

Since humans have the aforementioned natural physiological phenomenon of binocular vision, in this embodiment, a camera unit 50 can be set in front of the user (FIG. 6) to capture the image of the user's right eye E2 Pupil image, in this way, it can be determined whether the pupil of the user's right eye E2 is narrowed according to the image, so that it can be inferred whether the first bright line L1 has entered the field of view of the user's left eye E1, so as to avoid directly passing through the camera When the unit 50 captures the left eye E1, it is affected by the light of the first bright line L1, resulting in a measurement error.

As shown in FIG. 7, after performing the above steps and obtaining the data of the first reference distance ML, the left lens 12 can be projected at a first right limit position within the projection range of the optical engine of the left lens 12 A second bright line L2 is generated. At this time, since the second bright line L2 is located outside the field of view of the user's left eye E1, the pupils of the user's left and right eyes E1 and E2 will not be affected by the second bright line. The light effect of L2 is reduced.

However, when the second bright line L2 moves a distance to the left from the first right limit position shown in FIG. 7 and enters the visual field of the user’s left eye E1 ( FIG. 8 ), the user’s left eye E1 The pupil of the user will be reduced by the light of the second bright line L2, and the pupil of the user's right eye E2 will also be reduced accordingly. At this time, the camera unit 50 can capture the image of the pupil of the user's right eye E2, and determine whether the pupil of the user's right eye E2 is constricted according to the image, so as to infer whether the second bright line L2 has entered use within the visual field of the left eye E1.

A fourth bright line L4 is projected at a second right limit position in the interior. At this time, since the fourth bright line L4 is located outside the field of vision of the user's right eye E2, the user's left and right eyes E1, E2 None of the pupils will be reduced by the light of the fourth bright line L4.

However, when the fourth bright line L4 moves a distance to the left from the second right limit position shown in FIG. 11 and enters the visual field of the user’s right eye E2 ( FIG. 12 ), the user’s right eye E2 The pupil of the user will be reduced by the light of the fourth bright line L4, and the pupil of the user's left eye E1 will be reduced accordingly. At this time, the aforementioned camera unit 50 can capture the image of the pupil of the user's left eye E1, and determine whether the pupil of the user's left eye E1 is constricted according to the image, so as to infer whether the fourth bright line L4 has entered use within the field of vision of the right eye E2.

It should be noted that, once the camera unit 50 detects that the pupil of the user's left eye E1 is constricted, it can record the position of the fourth bright line L4 on the right lens 22, and compare the fourth bright line L4 to the right lens 22.

After the optimal interpupillary distance value D is obtained, the relative positions of the left and right lenses 12 and 22 of the augmented reality glasses device can be adjusted according to the optimal interpupillary distance value D. For example, the two sliders R on the left and right mirror frames 11 and 21 in the second middle can be clamped with bare hands or through tools, and an external force can be applied to make the left and right mirror frames 11 and 21 pull apart or approach in the horizontal direction, and After the aforementioned calibration and adjustment procedures are completed, the first and second members 41 and 42 of the aforementioned telescopic mechanism 40 can maintain their lengths without sliding arbitrarily.

The calibration method for the augmented reality glasses device of claim 2, further comprising: Projecting a third bright line on a second left extreme position on the right lens; Use the camera unit to capture the image of the pupil of the left eye, and determine whether the pupil of the left eye is narrowed, wherein when the camera unit detects that the pupil of the left eye is not narrowed, the third bright line is removed from the second The left limit position is moved this distance to the right; and When the camera unit detects that the pupil of the left eye is narrowed, it records the position of the third bright line on the right lens, and defines the distance between the third bright line and the center position of the left and right lenses. Twice is a third reference distance mR. As claimed in claim 3, the method for calibrating the augmented reality glasses device further includes: Projecting a fourth bright line on a second right extreme position on the right lens; Use the camera unit to capture the image of the pupil of the left eye, and determine whether the pupil of the left eye is narrowed, wherein when the camera unit detects that the pupil of the left eye is not narrowed, the fourth bright line is removed from the second The right limit position is moved to the left by this distance; and When the camera unit detects that the pupil of the left eye is constricted, it records the position of the fourth bright line on the right lens, and defines the distance between the fourth bright line and the center position of the left and right lenses. Twice is a fourth reference distance MR. The calibration method of the augmented reality glasses device according to claim 4, wherein the calibration method of the augmented reality glasses device further comprises: An optimal interpupillary distance value D is calculated according to the first, second, third and fourth reference distances ML, mL, MR, and mR, where D=[min(MR,ML)+max(mR,mL)] /2. The calibration method of the augmented reality glasses device according to claim 5, wherein the calibration method of the augmented reality glasses device further comprises: The relative positions of the left and right lenses are adjusted according to the optimal interpupillary distance value D. An augmented reality glasses system, comprising: An augmented reality glasses device having a left lens, a right lens, a left frame, a right frame, and a telescopic mechanism connecting the left and right frames, wherein the left and right lenses are respectively disposed on the left and right frames inside, and respectively correspond to a left eye and a right eye of a user; and A camera unit is electrically connected to the augmented reality glasses device, wherein when the left lens shows a bright line, the camera unit captures an image of the pupil of the right eye, and determines whether the pupil of the right eye is constricted. The augmented reality glasses system of claim 7, wherein the augmented reality glasses system further comprises a notebook computer, wherein the camera unit is arranged on the notebook computer. The augmented reality glasses system of claim 7, wherein the augmented reality glasses device further has two temples and a guide rod connecting the temples, wherein the left and right mirror frames are slidably connected to the guide rod. The augmented reality glasses system of claim 9, wherein the augmented reality glasses device further has two sliders, respectively disposed on the left and right frames, and the sliders are slidably disposed on the on the guide rod.
