[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] Figure 1The figure shows a method step diagram of a method for controlling a light-transmitting bottom plate of a cable car cabin provided by an embodiment of the present application. The present application provides a method for controlling a light-transmitting bottom plate of a cable car cabin, which is applied to a cable car cabin, such as Figure 2 As shown, the cable car cabin 1 has a light-transmitting bottom plate 2, which includes a plurality of polymer dispersed liquid crystal films 201 arranged in an array, and a camera is arranged in the cable car cabin 1. In the default state, the polymer dispersed liquid crystal film 201 is energized and is transparent, that is, the entire light-transmitting bottom plate 2 is transparent.

[0029] like Figure 1 As shown, the light-transmitting bottom plate control method of the cable car car includes:

[0030] Step 110: Acquire the facial image of the passenger captured by the camera.

[0031] In this step, the camera takes real-time photos of the interior of the cable car cabin 1 to obtain facial images of each passenger.

[0032] Step 120: Obtain the pain degree of the corresponding passenger according to the facial image.

[0033] In this step, the degree of pain is evaluated by the facial image, and different degrees of pain corresponding to different facial images are pre-set, and the corresponding degree of pain is matched according to the facial image of the passenger photographed. Specifically, the degree of pain of the passenger can be evaluated by methods such as facial expression recognition algorithm, deep learning model, multimodal algorithm, etc. The more the passenger fears the high-altitude environment below the transparent bottom plate 2, the higher the degree of pain. For the pain intensity scoring, the facial expression of the passenger can be used as the scoring basis: facial muscle relaxation, eyelid tightening, frowning, upper lip lifting and wrinkling nose, lower lip lifting, and closing eyes, corresponding to the degree of pain of 0, 20%, 40%, 60%, 80%, and 100%, respectively. Based on the deep learning model, it is determined which degree of pain the facial expression of the photographed passenger has the highest similarity with, and the passenger is matched to the degree of pain. For another example, a facial expression pain model can be constructed using a deep learning model. By constructing a facial expression data set and a classification network for expression photos at different degrees of pain, and then matching and comparing with the deep learning model based on the facial expression images obtained by shooting, the degree of pain of the passenger is determined.

[0034] Step 130: If the degree of pain is greater than a preset degree, multiple polymer dispersed liquid crystal films 201 within the preset visual range of the passenger are switched to a scattering state.

[0035] In this step, when the degree of pain of a certain passenger is too great and exceeds the preset degree, multiple polymer dispersed liquid crystal films 201 within a certain range around the passenger are controlled to switch to a scattering state, so as to reduce the passenger's fear of heights, but it does not affect other passengers from viewing the scenery below. At the same time, passengers who are too afraid of heights can also view some scenery below through the polymer dispersed liquid crystal film 201 at a farther position. The preset degree can be pre-set, and the degree of pain can be set as a percentage value, that is, the range of the degree of pain is set to 0%~100%, and the larger the percentage value, the higher the degree of pain, so the preset degree can be set to a degree of pain of 60% or 70%.

[0036] Step 140: If the degree of pain of passengers exceeding a first preset number on a row of seats 10 is greater than a preset degree, a plurality of polymer dispersed liquid crystal films 201 within a preset range close to the seats 10 are switched to a scattering state.

[0037] Figure 2 is a schematic diagram of the internal structure of the cable car cabin. Figure 2 Some cable car cabins 1 are equipped with seats 10. When the pain level of more passengers on the seats 10 is too great, the polymer dispersed liquid crystal film 201 within a certain range from the seat 10 is switched to a scattering state to prevent most passengers on the seats 10 from being too frightened.

[0038] Step 150: If the pain level of the passengers exceeding the second preset number in the cable car cabin 1 is greater than the preset level, all polymer dispersed liquid crystal films 201 in the cable car cabin 1 are switched to a scattering state.

[0039] In this step, if too many passengers in the cable car cabin 1 feel uncomfortable, all the polymer dispersed liquid crystal films 201 are switched to a scattering state, that is, the entire light-transmitting bottom plate 2 is controlled to switch to an opaque state.

[0040] Step 160 , obtaining a control signal and regulating the polymer dispersed liquid crystal film 201 to switch to a light-transmitting state corresponding to the control signal.

[0041] In this step, the light transmittance state of some polymer dispersed liquid crystal films 201 can be controlled according to specific requirements, and the specific requirements can come from the operation control of the passengers in the cable car cabin 1, or from the remote control of the remote end.

[0042] When this embodiment is used, the reaction state of passengers in the cable car cabin 1 to the high-altitude scenery below the light-transmitting bottom plate 2 can be obtained in real time, and different control logics can be executed according to the specific reaction state to adaptively meet different passenger states. When a passenger is too scared, the polymer dispersed liquid crystal film 201 within a certain range near the passenger can be controlled to switch to an opaque state; when too many passengers on the seat feel more scared, the polymer dispersed liquid crystal film 201 near the seat is switched to an opaque state; when too many passengers in the entire cable car cabin 1 feel more scared, the entire light-transmitting bottom plate 2 is switched to an opaque state; when there are special control instructions, the corresponding light-transmitting state switching work can be executed.

[0043] Figure 3 FIG. 1 is a structural diagram of a light-transmitting bottom plate. Figure 3 As shown, the polymer dispersed liquid crystal film 201 is in a strip shape, and the transparent bottom plate 2 is provided with at least two rows of working groups along the first direction X. A single working group includes a plurality of polymer dispersed liquid crystal films 201 arranged in parallel along the second direction Y, and the second direction is perpendicular to the first direction. Multiple working groups are arranged to form the transparent bottom plate 2, and the position and size of the opaque area can be more finely controlled.

[0044] Figure 4 FIG. 2 is a structural diagram of a light-transmitting bottom plate provided by another embodiment. Figure 4 As shown, the polymer dispersed liquid crystal film 201 is in a square shape, and a plurality of polymer dispersed liquid crystal films 201 are arranged in an array to form a grid, so that the position and size of the opaque area can be more finely controlled.

[0045] Figure 5 FIG. 1 is a schematic diagram of the steps of a light transmission control method when the degree of pain is greater than a preset degree provided by another embodiment of the present application. Figure 5 As shown, step 130 includes:

[0046] Step 131 : If the degree of pain is greater than a preset degree, obtain the vertical height of the passenger's eyes relative to the light-transmitting bottom plate 2 .

[0047] In this step, the height and posture of the passenger, whether standing or sitting, can be known based on the vertical height, and the opaque area is adjusted based on the actual vertical height.

[0048] Step 132: Switch the polymer dispersed liquid crystal film 201 in the conical coverage area between the reference indication line and the vertical line to a scattering state according to the vertical height.

[0049] Figure 6 The figure shows the cone-shaped visual area between the passenger's reference indicator line and the vertical line. Figure 6, the vertical line L is the shortest line segment between the eye S and the light-transmitting bottom plate 2, and the reference indicator line M is the visible line of sight of the eye at a preset angle with the vertical line L, and the preset angle is any value between 30° and 60°. The reference indicator line M circles the vertical line L to form a visible light cone of the eye S, and the projection N of the visible light cone on the light-transmitting bottom plate 2 is the aforementioned conical coverage area, and the polymer dispersed liquid crystal film 201 within the projection N is switched to a scattering state. The distance of the polymer dispersed liquid crystal film 201 outside the conical coverage area is relatively far, and the impact on the passengers is relatively small, so it is considered not to be switched to a scattering state.

[0050] Figure 7 The figure shows a schematic diagram of the light transmission control method steps when the pain level of more than 1 / 2 of the passengers on the seat is greater than the preset level. Figure 7 As shown, step 140 includes:

[0051] Step 141 : If the pain level of more than 1 / 2 of the passengers on the seat 10 is greater than a preset level, a plurality of polymer dispersed liquid crystal films 201 within a preset distance close to the seat 10 are switched to a scattering state.

[0052] In this embodiment, the polymer dispersed liquid crystal film 201 within a preset distance from the seat 10 is switched to a scattering state, and the preset distance can be set to any value between 1m and 1.5m.

[0053] Figure 8 The figure shows a schematic diagram of the light transmission control method steps when the pain level of more than 2 / 3 of the passengers in the cable car cabin is greater than a preset level. Figure 8 As shown, step 150 includes:

[0054] Step 151: If the pain level of more than two-thirds of the passengers in the cable car cabin 1 is greater than a preset level, all polymer dispersed liquid crystal films 201 in the cable car cabin 1 are switched to a scattering state.

[0055] In this embodiment, all the polymer dispersed liquid crystal films 201 are switched to the scattering state.

[0056] Fig. 9 FIG. 2 is a schematic diagram of a method for controlling light transmission according to a first control signal provided in another embodiment of the present application. Fig. 9 As shown, step 160 includes:

[0057] Step 161 : Obtain a first control signal to switch a plurality of mutually spaced polymer dispersed liquid crystal films 201 to a scattering state.

[0058] In this embodiment, the first control signal is sent by the operator inside the cable car car 1 or the remote controller outside the cable car car 1, that is, the light transmittance states of adjacent polymer dispersed liquid crystal films 201 are opposite, and the entire light-transmitting bottom plate 2 is in an intermittent light-transmitting state, which enables passengers to see a certain scenery below without causing too much fear of heights.

[0059] Fig.10 FIG. 2 is a schematic diagram of a method for controlling light transmission according to a second control signal provided in another embodiment of the present application. Fig.10 As shown, step 160 includes:

[0060] Step 162 , obtaining a second control signal, switching a plurality of mutually continuous polymer dispersed liquid crystal films 201 to a scattering state, so as to reduce the size of the light-transmitting area of ​​the light-transmitting bottom plate 2 .

[0061] In this embodiment, the second control signal is sent by the controller in the cable car cabin 1 or the remote controller outside the cable car cabin 1. The size of the light-transmitting area can be reduced to reduce the passengers' fear of heights, and at the same time, the light-transmitting state of the adjacent polymer dispersed liquid crystal film 201 will not be in the opposite state, that is, the passengers can still see the complete scenery below from the reduced light-transmitting area without the problem of the scenery being blocked.

[0062] Specifically, the multiple polymer dispersed liquid crystal films 201 switched to the scattering state form a scattering area, and the scattering area is connected to the edge contour of the light-transmitting bottom plate 2, that is, the light-transmitting area is reduced around the edge contour of the light-transmitting bottom plate 2. Generally, the light-transmitting bottom plate 2 is located between the seats 10 on both sides, and the scattering area is connected to the edge contour of the light-transmitting bottom plate 2, so that the polymer dispersed liquid crystal film 201 adjacent to the seat 10 can be switched to non-transparent, and the area of ​​the light-transmitting bottom plate 2 far away from the seat 10 is a transparent area, that is, the transparent area is far away from the passengers, and the passengers can watch the scenery below without having too much fear of heights.

[0063] Fig.11 The present application also provides a cable car cabin light-transmitting bottom plate control system, which is applied to a cable car cabin, referring to Figure 2 The cable car cabin 1 has a light-transmitting bottom plate 2, which includes a plurality of polymer dispersed liquid crystal films 201 arranged in an array.

[0065] The data acquisition module 1101 is configured to acquire the facial image of the passenger captured by the camera.

[0066] The passenger status analysis module 1102 is in communication connection with the data acquisition module 1101 , and the passenger status analysis module 1102 is configured to obtain the pain degree of the corresponding passenger according to the facial image.

[0067] The switching control module 1103 is communicatively connected with the passenger status analysis module 1102, and the switching control module 1103 is configured as follows: if the degree of pain is greater than a preset degree, multiple polymer dispersed liquid crystal films 201 within a preset visual range of the passenger are switched to a scattering state; if the degree of pain of more than a first preset number of passengers on a row of seats 10 is greater than the preset degree, multiple polymer dispersed liquid crystal films 201 within a preset range close to the seats 10 are switched to a scattering state; if the degree of pain of more than a second preset number of passengers in the cable car cabin 1 is greater than the preset degree, all polymer dispersed liquid crystal films 201 in the cable car cabin 1 are switched to a scattering state; and a control signal is obtained and the polymer dispersed liquid crystal film 201 is adjusted to switch to a light-transmitting state corresponding to the control signal.
