DETAILED DESCRIPTION

[0044] like Figure 1-4 As shown, the light blocking method of the light-transmitting medium is:

[0045] Continuously acquiring at least one human body image detected by the human body image acquisition unit 2 within a preset acquisition time period;

[0046] The human body image brightness judgment unit 3 performs brightness detection on each acquired human body image to detect whether there is an area in the human body image that exceeds a preset brightness;

[0047] If there is an area exceeding the preset brightness in the human body image, the transmittance of several electrochromic modules 11 on the transparent medium 1 is changed. The several electrochromic modules 11 whose transmittance is changed are the several electrochromic modules 11 through which light passes when the light source irradiates the area exceeding the preset brightness.

[0048] Continuously acquiring at least one detected human body image within a preset acquisition time period by the human body image acquisition unit 2;

[0049] The human body coordinate calculation unit 4 calculates the spatial coordinates of the human body image feature points of each human body image in the spatial coordinate system;

[0050] Continuously collecting at least one light source detected by the light source detection unit 5 within a preset acquisition time period;

[0051] The light source coordinate calculation unit 6 calculates the spatial coordinates of the light source feature point of each light source in the spatial coordinate system;

[0052] Calculate the spatial coordinates of the intersection point when the light source passes through the transparent medium 1 according to the obtained spatial coordinates of the characteristic points of the human body image and the spatial coordinates of the characteristic points of the light source;

[0053] And the transmittance of the electrochromic module 11 located on the intersection coordinate is changed according to the intersection coordinate.

[0054] The characteristic points of the human body image are several outer contour points of the eye; while changing the transmittance of the electrochromic module 11 at the intersection coordinates, the transmittance of several electrochromic modules 11 between two adjacent electrochromic modules 11 and the transmittance of the electrochromic module 11 enclosed in the outer contour are changed.

[0055] The light source feature point includes a central light source feature point of the light source;

[0056] Human body image feature points include facial feature points.

[0057] The facial feature point is the eye feature point at the center of the eye. While changing the transmittance of the electrochromic module 11 located at the intersection coordinate, the transmittance of the electrochromic module 11 within several preset ranges around the light source feature point is changed.

[0058] Specifically, Figure 1 Said

[0059] Assuming that the optical medium is a plane, the plane where the transparent medium 1 is located is taken as the YZ section, and any point on the transparent medium 1 is taken as the coordinate origin to construct a three-dimensional coordinate system. The α coordinate and the β coordinate are located in the three-dimensional coordinate system on both sides of the YZ section. α is the light source, and β is the illuminated point (or area) where the light brightness needs to be reduced.

[0060] Point α is the real-time position detected by the light sensor and distance sensor.

[0061] Point β is the real-time position detected by the distance sensor and computer software.

[0062] Assuming that the coordinates of points α and β in the three-dimensional coordinate system are measured to be (a, b, c) and (d, e, f) respectively, the coordinates of the intersection of the line connecting points α and β and the cross section of the optical medium can be calculated to be (0, (bd-ae) / (da), (cd-af) / (da)).

[0063] The brightness of the β point is reduced by darkening the color of the optical medium at (0, (bd-ae) / (da), (cd-af) / (da)) to reduce the light transmission rate.

[0064] When points α and β move at high speed, the coordinate data measured by the sensor needs to be the coordinate data measured at the same time.

[0065] The shape of the light-transmitting medium 1 may be a plane, a curved surface or other arbitrary shapes.

[0066] The speed at which the electrochromic module 11 of the light-transmitting medium 1 changes color must be faster than 1 / 24 second in order to produce a better effect.

A power on and off module 163 is provided between each electrochromic module 11 and the first light-transmitting conductive plate 161 or the second light-transmitting conductive plate 162. Several power on and off modules 163 are respectively connected to the control circuit 12 through signal transmission components; the control circuit 12 is also connected to a human body image acquisition unit 2 and a human body image brightness judgment unit 3.

[0079] At the same time, continue to collect whether the brightness of the area exceeding the preset brightness in the detected human body image is lower than the preset brightness;
