[ Detailed description ] of the invention
In order to make the objects, technical solutions and advantageous technical effects of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and detailed description. It should be understood that the detailed description is intended to illustrate the invention, and not to limit the invention.
Referring to fig. 1, in an embodiment of the present invention, an apparatus 100 for mapping a mirror image to an electronic screen is provided for synchronously mapping and displaying images displayed on a mirror in the electronic screen, for example, images in a rearview mirror of an automobile can be synchronously displayed on a display device in the automobile, so as to facilitate observation of a driver.
The device 100 for mapping a mirror image onto an electronic screen comprises a mirror body 10 with a mirror surface 11, a transparent light processing module layer 20 arranged on the mirror surface 11, a reflecting layer 30 arranged on the side, away from the mirror surface 11, of the light processing module layer 20 and having semi-permeability, an image acquisition module 40, a processor 50 electrically connected with the image acquisition module 40 and an electronic screen 60 electrically connected with the processor 50. The black arrow lines in fig. 1,2 and 3 are schematic diagrams of incident light.
One side of the mirror body 10 is provided with a mirror surface 11, and the mirror surface 11 can be a plane mirror or a concave mirror or a convex mirror.
The light processing module layer 20 is used for filtering the incident light before entering the mirror 11. The incident light comprises direct light and scattered light before entering the mirror surface, and the direct light and the scattered light can cause adverse phenomena such as overlarge local exposure or fuzzy boundary among objects of a picture during imaging, so that the imaging effect of the incident light on the mirror surface is affected; or the incident light rays can form a plurality of halations with different sizes during imaging, so that the influence on normal objects is blocked, and the imaging quality is also influenced. Therefore, it is necessary to filter the direct light and the scattered light in the incident light to remove the halation.
Specifically, the light treatment module layer 20 includes a photosensitive layer and an anti-halation layer. The photosensitive layer is also called an emulsion layer and comprises silver salt (such as silver halide) and gelatin, and can effectively absorb scattered light and direct light so as to filter incident light; the anti-halation layer is used for preventing incident light rays from generating halation. The specific principles are referred to in the art and are not limited herein.
The reflecting layer 30 is used for reflecting the incident light rays reflected by the mirror surface; wherein the light reflected by the reflecting layer 30 has an included angle with the light reflected by the mirror 11.
Specifically, the incident light enters the mirror 11 after the filtering process, and is then reflected by the mirror 11 to the reflective layer 30. The reflective layer 30 is a reflective lens, and when incident light enters the mirror surface from the outside through the reflective layer 30, the reflective layer 30 does not block the incident light; when the incident light is reflected by the mirror 11 to the reflective layer 30, the reflective layer 30 reflects the incident light, and the reflected angle forms an included angle with the direction of the mirror 11 reflected to the reflective layer 30. In this embodiment, the reflective layer 30 reflects the incident light rays from the mirror 11 into the image capturing module 40, that is, the image capturing module 40 can perform image capturing on the incident light rays reflected by the reflective layer. In addition, in other embodiments, the reflective layer 30 may also be disposed between the mirror 11 and the anti-halation layer.
The image acquisition module 40 is configured to receive and sense the incident light reflected by the reflective layer 30 to form an image sensing signal, and send the image sensing signal to the processor 50.
Specifically, the image acquisition module 40 may be a device such as an image sensor capable of electronizing an image, and may acquire incident light to form an image sensing signal, and send the image sensing signal to the processor 50 for analysis.
Further, the image capturing module 40 includes an infrared capturing module (not shown in the figure) for capturing infrared rays in the incident light rays to form an infrared image signal, and transmitting the infrared image signal to the processor. Some portions of the visible light that are blocked may be identified using infrared imaging, such as infrared thermal imaging, or infrared optical imaging, and objects with higher heat, such as pedestrians on the road, may be identified.
The processor 50 is configured to receive the image sensing signal sent by the image acquisition module 40, perform operation processing to obtain an image processing result, and send the image processing result to the electronic screen 60.
The processor 50 can analyze and identify the image sensing signal, restore the image sensing signal into real-time image data, and simultaneously perform a big data set grouping algorithm on the image data to identify the relative position and the relative motion relationship between the pedestrian and the mirror 11 in the image data, thereby judging whether the pedestrian and the mirror collide with each other or not, and effectively playing a role in reminding and alarming.
The electronic screen 60 is used for presenting the image processing results sent by the processor. That is, the electronic screen displays the image in the mirror surface in real time or with a delay, that is, the mirror image is electronic.
Optionally, referring to fig. 2, in one embodiment, the apparatus 100 for mapping a specular image to an electronic screen further includes a transparent hydrophobic layer 70 disposed on a side of the reflective layer 30 facing away from the light processing module layer 20; the hydrophobic layer 70 serves to prevent the droplets from adhering. Specifically, the hydrophobic layer may be a hydrophobic organic film or a nanomaterial, so that liquid such as water drops can be effectively prevented from adhering to the mirror 11, resulting in poor light and shadow collection effect.
Optionally, referring to fig. 3, in one embodiment, an image capturing module 80 electrically connected to the processor 50 is further disposed on a side of the mirror body 10 near the mirror surface 11, and the image capturing module 80 is configured to capture an image in front of the mirror surface 11 to form image data and send the image data to the processor 50.
Specifically, the image capturing module 80 may further capture the environmental object presented in the mirror surface, send the captured environmental object to the processor 50 for analysis, and compare the captured image with the image captured by the image capturing module 40 to optimize the image effect presented on the electronic screen 60. In particular, the image capturing module 40 may be turned off, and the image in front of the mirror 11 is captured only by the image capturing module 80 and processed by the processor 50 and then displayed on the electronic screen 60.
In summary, the light processing module layer 20 filters the incident light incident on the mirror 11, so that the image effect presented in the mirror 11 is better, and the image mapped on the electronic screen 60 has the advantages of being clearer, and is beneficial to improving the driving safety.
Another aspect of the present invention is to provide a method for mapping a mirror image to an electronic screen, which is implemented by the apparatus 100 for mapping a mirror image to an electronic screen, so that the implementation manner and the principle are the same, and thus a detailed description is omitted herein.
As shown in fig. 4, the method of mapping the mirror image to the electronic screen includes the following steps S101 to S105.
In step S101, the light processing module layer 20 filters the incident light to the mirror 11.
In step S102, the mirror 11 receives the filtered incident light and reflects the light to the reflective layer 30.
In step S103, the reflective layer 30 receives the incident light reflected by the mirror 11, and reflects the incident light to the image capturing module 40.
In step S104, the image capturing module 40 receives and senses the incident light reflected by the reflective layer 30 to form an image sensing signal and sends the image sensing signal to the processor 50.
In step S105, the processor 50 receives the image sensing signal sent by the image acquisition module 40, performs an operation process to obtain an image processing result, and sends the image processing result to the electronic screen 60.
In step S106, the electronic screen 60 presents the image processing result transmitted by the processor 50.
Further, as shown in fig. 5, in one embodiment, step S101 includes step S1011: the photosensitive layer filters scattered light and direct light in incident light; and step S1012: the anti-halation layer performs halation treatment on incident light.
Optionally, step S104 includes the steps of: the infrared capturing module captures infrared rays in the incident light rays to form infrared image signals, and sends the infrared image signals to the processor 50.
Optionally, as shown in fig. 6, in an embodiment, step S107 is further included before step 105: the image capturing module 80 captures an image in front of the mirror 11 to form image data and sends the image data to the processor 50.
In summary, the method for mapping a mirror image to an electronic screen provided by the present invention also has functions and effects that can be achieved by the apparatus 100 for mapping a mirror image to an electronic screen.
The present invention is not limited to the details and embodiments described herein, and thus additional advantages and modifications may readily be made by those skilled in the art, without departing from the spirit and scope of the general concepts defined in the claims and the equivalents thereof, and the invention is not limited to the specific details, representative apparatus and illustrative examples shown and described herein.
