Detailed Description

In order to make the technical problems solved, the technical solutions adopted and the technical effects achieved by the present invention clearer, the technical solutions of the present invention are further described below by way of specific embodiments with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the elements associated with the present invention are shown in the drawings.

Example one

The embodiment provides a holographic projection brightness adjusting system which is used for adjusting the brightness of a floating imaging display image in holographic projection. As shown in fig. 1, the holographic projection brightness adjusting system includes acollecting device 11, a data processing device 12 and an adjusting device 13.

The data processing device 12 is used for determining the light transmittance of the adjusting device 13 according to the light intensity information and generating an adjusting instruction. The data processing device 12 may be a control host in the vehicle, which may include one or more processors and storage devices for storing one or more programs, which when executed by the one or more processors, enable the one or more processors to determine the light transmittance of the adjustment device 13 from the light intensity information and generate adjustment instructions.

The adjusting device 13 is used for adjusting the light transmittance according to the adjusting instruction after receiving the adjusting instruction, so as to adjust the brightness of the holographic projection system. The adjusting device 13 is disposed on the holographic projection system, and the light transmittance is variable. The adjusting device 13 may have a plurality of light transmittances, and the adjusting device 13 can adjust its light transmittance to the light transmittance indicated by the adjusting instruction according to the adjusting instruction.

In summary, in the holographic projection brightness adjustment system provided in this embodiment, thecollecting device 11 can collect light intensity information of ambient light, and the data processing device 12 can determine the light transmittance of the adjusting device 13 located on the holographic projection system according to the light intensity information, and then adjust the display brightness of the holographic projection system through the adjusting device 13, so as to prevent dazzling of floating imaging in the holographic projection system, so that a driver can clearly see an image of the floating imaging, and a risk of traffic problems is reduced.

Optionally, theacquisition device 11 in this embodiment comprises a photosensitive sensor. And thecollection device 11 may be located anywhere within the vehicle, preferably thecollection device 11 may be located on the dashboard of the vehicle. Because the instrument desk is closer to the position of the floating imaging, the light information detected by theacquisition device 11 is closer to the light intensity information of the position of the floating imaging, so that when the intensity or brightness of the light at the position of the floating imaging changes, theacquisition device 11 can transmit the information to the data processing device 12 in a short time, the response speed and the response capacity of the holographic projection brightness adjusting system are further improved, and the adjusting effect of the holographic projection brightness adjusting system is ensured.

The adjusting means 13 in this embodiment is arranged on an optical element in the holographic projection system, or the adjusting means 13 is arranged on a display screen in the holographic projection system. When the adjusting device 13 is disposed on the optical element, when the light transmittance of the adjusting device 13 changes, the intensity and brightness of light emitted from the optical element to the outside will change, and the brightness of the image in the floating imaging can be adjusted through the optical element. When adjusting device 13 sets up on the display screen, when adjusting device 13's luminousness changed, the intensity and the luminance that the display screen outwards sent light will change for the intensity and the luminance of the light that the display screen sent optical element change, thereby make the luminance of figure change in the superficial formation of image, and then can adjust the luminance of image in the superficial formation of image through the display screen.

Further, as shown in fig. 2, when the adjusting device 13 is disposed on the optical element, the adjusting device 13 may be disposed on the light emitting surface of the optical element. The light-emitting surface of the optical element is close to the floating imaging, and when the adjusting device 13 is arranged on the light-emitting surface of the optical element, the imaging effect of the image in the floating imaging can be better after the adjustment of the adjusting device 13. The light-emitting surface can be the surface of the optical element on the side close to the floating imaging. Wherein the optical element may be glass having a predetermined refractive index and scattering power.

Alternatively, as shown in fig. 3, the adjusting device 13 may include anintelligent adjusting film 131, the adjusting instruction may be an electrical signal value, and theintelligent adjusting film 131 can adjust to the light transmittance according to the electrical signal value. At this time, the data processing device 12 determines the light transmittance of thesmart adjustment film 131 according to the light intensity information, and generates an electric signal value to transmit to thesmart adjustment film 131. After receiving the electrical signal value, theintelligent adjusting film 131 adjusts the light transmittance thereof according to the magnitude of the electrical signal value, thereby adjusting the brightness of the image on the floating image in the holographic projection system.

Specifically, theintelligent adjustment film 131 in this embodiment may be an electrically driven intelligent adjustment film capable of adjusting the light transmittance according to the value of the electrical signal transmitted by the data processing device 12. For example, the light transmittance of thesmart adjustment film 131 may be positively correlated with the value of the electrical signal transmitted from the data processing device 12 to thesmart adjustment film 131, and at this time, the greater the electrical signal transmitted from the data processing device 12 to thesmart adjustment film 131, the more thecurl 1312 is rolled up, the greater the light transmittance of thesmart adjustment film 131.

Theintelligent adjusting film 131 can be attached to an optical element or a display screen of the holographic projection system. And, when thesmart adjustment film 131 is attached to theoptical element 22, it may be attached to the light emitting surface of theoptical element 22. The electrical signal value may be a current value, a voltage value, or the like, which is not limited in this embodiment.

Further, as shown in fig. 4, thesmart adjustment film 131 may include amain body portion 1311 and a plurality ofcurls 1312, and the plurality ofcurls 1312 may be capable of being stretched or curled by the above-described electric signal value to adjust the light transmittance of thesmart adjustment film 131.

For example, thecurl 1312 may have an extended state and a curled state, and when the plurality ofcurls 1312 are all in the extended state, the light transmittance of thesmart adjustment film 131 is zero. When the plurality of curledportions 1312 are all in a curled state, the light transmittance of thesmart adjustment film 131 is not zero. And the light transmittance of the smart light-transmitting film is positively correlated with the amount ofcurl 1312. That is, the more thecurl 1312 is rolled up, the greater the light transmittance of the intelligent light-transmitting film. Accordingly, there is a correspondence between the electric signal value and the amount ofcurl 1312, that is, the amount ofcurl 1312 is related to the magnitude of the electric signal value. For example, the greater the electrical signal value, the greater the amount thatcurl 1312 is curled up.

Still further, as shown in fig. 4, a plurality of curledportions 1312 are arranged in an array on themain body portion 1311, and the curling directions of two adjacent rows of curledportions 1312 are opposite to each other, and the curling direction is a rotational direction in which the curledportions 1312 are curled. That is, the openings of the two adjacent rows of thecurl portions 1312 are oriented differently. When theintelligent regulation membrane 131 has this structure, theintelligent regulation membrane 131 can have more even transmittance, has avoided the display blind area because of the inhomogeneous production of printing opacity, has further improved user's experience effect.

Alternatively, as shown in fig. 3, the data processing apparatus 12 in the present embodiment may include aprocessing unit 121 and anarithmetic unit 122. Theprocessing unit 121 is configured to determine the light transmittance of the adjusting device 13 according to the light intensity information, and thealgorithm unit 122 is configured to determine an electrical signal value according to the light transmittance and send the electrical signal value to the adjusting module.

Alternatively, theprocessing unit 121 may have various ways of determining the light transmittance of the adjusting device 13 according to the light intensity information, and the present embodiment provides the following two ways. In one mode, theprocessing unit 121 may pre-store a corresponding relationship between the light intensity information and the light transmittance of the adjusting device 13, and at this time, after theprocessing unit 121 receives the light intensity information sent by the collectingdevice 11, the light transmittance that the adjusting device 13 should have may be determined according to the corresponding relationship, so that the brightness of the image displayed by the floating imaging meets the needs of the user under the light transmittance. In another mode, a relational expression between the light intensity information and the light transmittance of the adjusting device 13 is stored in theprocessing unit 121, and at this time, after theprocessing unit 121 receives the light intensity information sent by the collectingdevice 11, the light intensity information is substituted into the relational expression, so that the light transmittance which the adjusting device 13 corresponding to the light intensity information should have can be obtained.

Further, the data processing device 12 may further include a communication unit, which may be used for communication between the data processing module and the acquisition module, and between the data processing module and the adjustment module. For example, the communication unit may be configured to receive the light intensity information sent by the collection module and transmit the light intensity information to theprocessing unit 121.

And S51, determining the light transmittance of the adjusting device according to the light intensity information, and generating an adjusting instruction.

Alternatively, the adjustment instruction in this embodiment may be an electrical signal value. At this time, step S51 may include:

and determining the light transmittance of the adjusting device according to the light intensity information.

And determining the value of the electric signal according to the light transmittance.

Accordingly, step S52 may include:

and adjusting the light transmittance according to the electric signal value.
