Further, in the description of the present application, "a plurality" means two or more unless specifically defined otherwise.

Referring to fig. 1 to 2, an underwater imaging device provided in the present application will now be described. The underwater image forming apparatus includes a water tank 1, an image forming structure, and a polarizing film 9.

The underwater imaging device has a projection area, a live-action area and an ornamental area, and the live-action area is located between the projection area and the ornamental area.

The tank 1 is used for loading liquid. The upper part of the water tank 1 is a real scene area, and the liquid surface is a reflecting surface 2. The water tank 1 is a container for containing a liquid, and may be in a cylinder shape, a barrel shape, or other shapes, and those skilled in the art may select the material and size of the water tank 1 according to actual needs, and the material and size are not limited herein. The liquid can be landscape water, drinking water and the like, and can also be wine or beverage as long as the liquid surface can reflect light.

The projection district is located to the formation of image structure, and the formation of image structure includes display 4 and air imaging plate 3, and display 4 is located one side that air imaging plate 3 deviates from the real scene district and through air imaging plate 3 in real scene district generation aerial image 6, and aerial image 6 can reflect to the viewing area through plane of reflection 2.

The polarizing film 9 is arranged on one side of the air imaging plate 3 facing the real scene area, and the polarizing film 9 receives the light from the air imaging plate 3 and limits the light to be emitted towards the reflecting surface 2.

For convenience of description, referring to the direction of the drawing of fig. 2, the upper part of the water tank 1 is a real scene area, the upper left part is an ornamental area, and the upper right part is a projection area.

It will be appreciated that the underwater imaging apparatus includes a base 13. In the illustrated structure, the base 13 is located on the right side of the water tank 1, and the water tank 1 is fixedly connected to the base 13. The air imaging plate 3 and the display 4 are provided on the base 13. In other embodiments, the sink 1 and the base 13 may be integrally formed or detachably connected. The sink 1 may be disposed on a side of the base 13 or may be supported by the base 13, which is not limited herein.

The base 13 is used for fixedly supporting the imaging structure, and more importantly, the base 13 fixes the relative positions of the water tank 1, the air imaging plate 3 and the display 4 to ensure the imaging effect of the underwater image.

The imaging structure comprises a display 4 and an air imaging plate 3, and the air imaging plate 3 is a flat lens structure for an existing aerial image 6. The air imaging plate 3 is capable of imaging the image source in a mirror image. The display 4 serves as a light source and an image source, and light with image information emitted by the display passes through the air imaging plate 3 to form an aerial image 6 on the other side of the air imaging plate 3. The display 4 is one of an LCD, LED, OLED, LCOS.

Please refer to fig. 1, which illustrates an example of the air imaging plate 3 being vertically disposed. The imaging structure is located in the upper right (imaging zone) of the water tank 1 and the aerial image 6 generated by the imaging structure is located in the real scene zone above the water tank 1. The aerial image 6 is reflected by the reflective surface 2 to form an inverted virtual image which is symmetrical to the aerial image 6 about the reflective surface 2. The viewer 8 can see the reflective surface 2 and a virtual image of the air image reflected by the reflective surface 2, which appears to be underwater, in the viewing area, to achieve the visual effect of the underwater image 7, and for convenience of description, the virtual image will be hereinafter collectively referred to as the underwater image 7.

The light source emitted from the display 4 is emitted through the air imaging plate 3 in a diagonally downward direction toward the water tank 1 to form the aerial image 6 above the water tank 1, and the light traveling path does not pass through the viewing area, in other words, the light forming the aerial image 6 cannot directly enter the field of view of the viewer, so that the aerial image 6 is not visible to the viewer 8. The light rays forming the aerial image 6 are reflected by the reflection surface 2 to enter the field of view (viewing area) of the observer, so that the observer can see an underwater image 7 formed by the reflection of the aerial image by the reflection surface 2. Thus, with the present design, the viewer 8 can see the underwater image 7 but not the aerial image 6.

In this embodiment, a polarizing film 9 is attached to the air imaging plate 3 on the side facing the real scene. The polarizing film 9 serves to define the direction of the light transmitted from the air imaging plate 3 so that it can be emitted only in the direction toward the reflecting surface 2. In the absence of the polarizing film 9, incident light emitted from the display 4 passes through the air imaging plate 3 and is emitted, and most of the emitted light is emitted in the direction of the water tank 1 and focused to form the aerial image 6, and at the same time, part of the emitted light is scattered and radiated to the periphery and partially falls into the field of view of the viewer 8, so that the viewer 8 can see the display screen. The arrangement of the polarizer 9 enables the incident light emitted from the display 4 to penetrate through the air imaging plate 3 and then to be emitted outward through the polarizer 9 at a specific angle, which is the direction from the air imaging plate 3 to the aerial image 6, in other words, the polarizer 9 only transmits the light required for forming the aerial image 6, and blocks or diffusely reflects the light directly incident into the viewing area, thereby preventing the viewer 8 from directly observing the display 4.

In view of the above, the underwater imaging device provided in the embodiment of the present application is configured such that the viewer 8 cannot see the aerial image 6 generated by the imaging structure, but only can see the underwater image 7 corresponding to the aerial image 6, and the viewer 8 cannot see the display 4 through the arrangement of the polarizing film 9. The invisibility of the aerial image 6 and the display 4, i.e. the manner in which the viewer 8 has difficulty in knowing the origin of the underwater image 7 by direct eye observation, stimulates the viewing pleasure of the viewer 8. In addition, the underwater image 7 in the scheme can be a two-dimensional plane image or a three-dimensional stereo image, so that the ornamental attraction is further increased.

Referring to fig. 2, the underwater imaging device further includes a cover 12, the cover 12 is disposed on the base 13 and encloses with the air imaging plate 3 to form a cavity for accommodating the display 4, and the cover 12 is made of opaque material. Can be made of rubber, plastic, metal materials and the like. The cover body 12, the base 13 and the air imaging plate 3 enclose to form a closed cavity, and the display 4 is located in the cavity. This arrangement provides protection and dust-proof effects for the display 4 on the one hand, and on the other hand, the cover body 12 is made of a light-tight material to prevent external light from entering the cavity and affecting the normal display of the display 4. Those skilled in the art may also apply a reflective layer to the side of the housing 12 facing the display 4 to cause more of the light emitted by the display 4 to exit the air imaging panel 3 and enhance the brightness of the aerial image 6.

In another embodiment of the present application, the air imaging plate 3 is at an angle of 60-90 ° to the horizontal. The included angle between the air imaging plate 3 and the horizontal plane is an included angle taking the surface of the air imaging plate 3 facing the water tank 1 as an edge and taking the liquid level of the water tank 1 as another edge, and the included angle is not more than 90 so as to ensure that the light source of the display 4 obliquely downwards emits to the liquid level of the water tank 1 after passing through the air imaging plate 3 and the polarizing film 9. With the aerial image 6 fixed in position, the display 4 adjusts the corresponding position according to the angle of the air imaging plate 3 so that the display 4 and the aerial image 6 are symmetrical with respect to the air imaging plate 3. It will be appreciated that with the lower end of the air imaging plate 3 fixed, the greater the angle of the air imaging plate 3 to the horizontal, the greater the extent of space left to shape the aerial image 6. But the larger the distance between the display 4 and the air imaging plate 3 in horizontal projection, in other words, the larger the lateral dimension occupied by the underwater imaging device. Conversely, the smaller the angle between the air imaging plate 3 and the horizontal plane, the smaller the range of space left for forming the aerial image 6, and the smaller the space of the underwater image 7 that can be formed by the underwater imaging device, and the more convenient it is for viewing. Through a plurality of experiments, the included angle between the air imaging plate 3 and the horizontal plane is 60-90 degrees, and the air imaging plate has a better imaging space and a more convenient observation range. Those skilled in the art can specifically set the included angle between the air imaging plate 3 and the horizontal plane to 60 °, 62 °, 63 °, 65 °, 66 °, 68 °, 70 °, 73 °, 74 °, 75 °, 76 °, 77 °, 79 °, 80 °, 81 °, 82 °, 84 °, 85 °, 86 °, 88 °, 89 °, 90 °, and the like according to actual needs, which is not limited herein.

In the illustrated embodiment, the air imaging plate 3 is perpendicular to the horizontal plane, i.e. the air imaging plate 3 is at an angle of 90 ° to the horizontal plane. This arrangement can simplify the structural design. In addition, when the reflecting surface 2 of the liquid is moved in the horizontal direction, the display 4 needs to be moved to keep the distance between the aerial image 6 and the reflecting surface 2 constant. In the case where the air imaging plate 3 is perpendicular to the horizontal plane, the up and down movement of the reflecting surface 2 and the up and down movement of the display 4 are synchronized, and therefore, this design can simplify the control.

In the embodiment of the present application, referring to fig. 1, the water tank 1 has a design water level for loading liquid, and the lower surface of the display 4 is flush with the design water level. The lower surface of the display 4 is flush with the design water level so that the aerial image 6 formed by the display 4 in the real field area is proximate to the liquid/reflective surface 2 of the tank 1, and the underwater image 7 is proximate to the liquid/reflective surface 2 of the tank 1. Thereby effectively avoiding the situation that the underwater image 7 deviates from the liquid level of the water tank 1 and exceeds the observation range of the viewer 8.

Specifically, referring to fig. 1, the bottoms of the air imaging plate 3 and the display 4 are all kept at the same level with the liquid level/reflective surface 2 of the water tank 1. The light emitted from the display 4 is collected into the air by the air imaging plate 3 to form an aerial image 6, and the aerial image 6 is positioned symmetrically with respect to the air imaging plate 3 relative to the display screen light source. The aerial image 6 is reflected by the reflective surface 2 to form an underwater image 7. Assuming that the air imaging plate 3 has a symmetrical virtual imaging plate 5 about the reflective surface 2, the field of view of the viewer 8 is formed by the eyes and the top and bottom of the virtual imaging plate 5, if the display 4 is far from the reflective surface 2, the underwater image 7 is deviated downward from the reflective surface 2 and may be out of the field of view of the viewer 8.

In this embodiment, the level of the water tank 1 filled with liquid is the design water level. In other embodiments, the design water level may be located at 4/5 or other locations of the volume of the sink 1, and is not limited herein.

When the design water level is lower than the full load water level, the sink 1 is provided with a water level marker at the design water level to provide guidance for the operator to load the liquid in the sink 1. It should be noted that there may be a plurality of design water levels, and correspondingly, there are a plurality of water level marks.

In another embodiment of the present application, the lower surface of the air imaging plate 3 extends at least to the level of the upper surface of the water bath 1. The air imaging plate 3 has the function of shielding the display 4 while the air imaging plate 3 shapes the image source of the display 4 into an aerial image 6 in the real scene area. The lower surface of the air imaging plate 3 extends to the level of the upper surface of the water tank 1 to avoid the situation that the display 4 is seen by the viewer 8 in the observation area due to the gap between the air imaging plate 3 and the water tank 1.

In the present embodiment, the air imaging plate 3 is fixed on the base 13 in an embedded manner, but a person skilled in the art may also fix the air imaging plate 3 on the side wall of the water tank 1, or use other fixing connection manners, which is not limited herein.

In another embodiment of the present application, the underwater imaging device further includes an adjusting structure for adjusting the position of the display 4, the adjusting structure adjusting the position of the display 4 according to the horizontal position of the reflecting surface 2, so that the aerial image 6 can be reflected to the viewing area through the reflecting surface 2.

In combination with the above, in the case where there are a plurality of design water levels, for example, there are five design water levels and they are located at 1/4, 1/2, 3/4, 4/5 of the height of the water tank 1, respectively. The operator pours the liquid into the water tank 1 and makes the liquid level reach one of the designed water levels, and then correspondingly controls the adjusting structure to make the display 4 reach the adjusting position corresponding to the designed water level.

In general, the surface of the liquid loaded in the water tank 1 is a reflection surface 2. The difference in the amount of liquid loaded in the water tank 1 causes the difference in the level of the reflecting surface 2. The arrangement of the adjusting structure enables the display 4 to be adjusted in position according to different horizontal positions, so that the distance between the aerial image 6 generated in the real scene area after the display 4 passes through the air imaging plate 3 and the polarizing film 9 and the reflecting surface 2 is kept unchanged. The distance between the corresponding underwater image 7 and the reflecting surface 2 is also kept constant from the perspective of the viewer 8, so that the viewer 8 can see the underwater image 7 at different liquid level heights.

The adjusting structure may be a linear module, a transmission screw rod or other structures as long as it can drive the display 4 to move linearly.

The adjusting structure can be driven manually or electrically.

Take the adjustment structure as a manual adjustment. The adjusting structure comprises a nut connected with the display 4 and a screw rod connected with the nut in a threaded manner, and the screw rod extends vertically. An operator can obtain the horizontal position of the reflecting surface 2 by observing the liquid level height through human eyes, and correspondingly rotate the screw rod according to the horizontal position height, so that the nut moves up and down together with the display 4.

In another embodiment of the present application, referring to fig. the underwater imaging device further includes a measuring device 10, the measuring device 10 is used for measuring the horizontal position of the reflective surface 2, and the adjusting structure adjusts the position of the display 4 according to the horizontal position, so that the aerial image 6 can be reflected to the viewing area through the reflective surface 2.

The measuring device 10 may be a water level gauge, an ultrasonic sensor, or the like. The horizontal position of the reflecting surface 2 is measured by the measurer 10, and compared with the observation by human eyes, the measurement is quicker and more accurate.

It will be appreciated that the underwater imaging device further comprises a controller electrically connected to the display 4, the measurer 10 and the adjustment structure, the controller receiving the water level height information measured from the measurer 10 and controlling the adjustment structure to operate to change the position of the display 4 in accordance with the water level height information.

In combination with the use scenario, an operator adds water into the water tank 1, so that the level rises. The measuring device 10 obtains the height of the liquid level/reflecting surface 2 and transmits the height information to the controller, and the controller controls the operation of the adjusting structure according to the height information of the water level. The adjusting structure drives the display 4 to ascend under the control of the controller, and the ascending distance of the display 4 is the same as the ascending distance of the horizontal position. Since the air imaging plate 3 is vertically placed, the display 4 is raised so that the aerial image 6 is raised synchronously, and the distance between the aerial image 6 and the reflecting surface 2 is kept consistent. At the angle of the viewer 8, the water level in the water tank 1 rises and the underwater image 7 also rises dynamically, thereby being full of interest.

In another embodiment of the present application, the underwater imaging apparatus further includes a water scooping device 11, and when the water scooping device 11 scoops up the liquid, the liquid surface of the water scooping device 11 is the reflecting surface 2. The water taking device 11 can be a water scooping tool such as a water cup, a bowl, a gourd ladle, a spoon and the like, and can also be a folded palm.

Referring to fig. 2, when the liquid is scooped up by the water dispenser 11 and raised by L2, the liquid surface (the reflective surface 2) of the water dispenser 11 is also raised by L2, and at this time, the adjustment structure raises the display 4 upward by L1 (the display 4 moves upward by L1 to the dashed box in fig. 2), the aerial image 6 generated in the real scene area by the display 4 via the air imaging plate 3 and the polarizing film 9 is also raised upward by L1, and L1 is L2, so that the distance between the aerial image 6 and the reflective surface 2 is kept constant, and correspondingly, the distance between the underwater image 7 and the reflective surface 2 is also kept constant, and the underwater image 7 moves upward by L2 from the water tank and is located at the dashed box in the water dispenser 11. From the perspective of the viewer 8, the underwater image 7 runs from the tank 1 into the water scooper 11, and has the illusion of scooping an entity from the tank 1 as the water scooper 11 lifts. For example, the aerial image 6 is an inverted fish, and the underwater image 7 is a forward fish. The viewer 8 sees the "fish" in the tank 1 under water, trying to scoop up the "fish" in the tank 1 together with the liquid with the closed hands. When the liquid is contained, the "fish" as the underwater image 7 is also surely transferred from the water bath 1 to the palm center, and the illusion that a solid fish is contained is generated. At this point, if the hand is released, the liquid in the palm falls into the sink 1 and the "fish" of the underwater image 7 is returned to the sink 1. In other words, the underwater imaging device provided by the embodiment interacts with the underwater image 7 by changing the height of the reflecting surface 2 through the water collector 11, the measurer 10 and the adjusting structure, so that the interest of the underwater imaging device is improved.

In another embodiment, the water tank 1 can be replaced by a fish tank, and real fish can be placed in the fish tank. The underwater imaging device generates an underwater image 7 under the reflective surface 2 within the aquarium, which underwater image 7 may be a brief introduction to some fish, or some virtual swimming fish. By the method, the viewing experience can be improved without damaging real fish schools.

In the present embodiment, measuring device 10 is an ultrasonic sensor. The ultrasonic wave emitted by the ultrasonic sensor can generate obvious reflection at the interface (the reflecting surface 2) of air and liquid to form reflection echo, and the position height of the reflecting surface 2 is obtained through the time analysis of the echo. The height of the reflecting surface 2 is measured by adopting the ultrasonic sensor, and the method has the following advantages: the device has the advantages that no mechanical transmission part is needed, the device is not contacted with the liquid to be measured, the device belongs to non-contact measurement, and the device is not afraid of electromagnetic interference, strong corrosive liquids such as acid and alkali and the like, so that the device has stable performance, high reliability and long service life; the response time is short, and the real-time measurement without lag can be conveniently realized.

Since the ultrasonic sensor is a non-contact measurement, the position of the reflecting surface 2 is changed by replacing the water tank 1 with a cup or other water container, or by placing another water container above the water tank 1. As long as the liquid level (reflecting surface 2) of the water container is positioned in the sensing range of the ultrasonic sensor, the adjusting structure drives the display 4 to make corresponding position adjustment, so that the underwater image 7 is transferred into the water container. Taking a water cup as an example, drinking water is added into the water cup, the water cup is arranged below the ultrasonic sensor so that the ultrasonic sensor can sense the position of the liquid level (the reflecting surface 2) of the water cup, and the aerial imaging device forms an underwater image 7 in the water cup.

In this embodiment, the measuring device 10 is provided directly above the water tank 1. The ultrasonic wave emitted by the ultrasonic sensor is perpendicular to the reflecting surface 2, so that the propagation path of the ultrasonic wave is shortened, and the response time of the adjusting structure is shortened.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
