Description

Technical Field

[0001] The present invention relates to the field of wireless transmission technology, and in particular to a method, device, electronic equipment and medium for wireless transmission of pictures. Background Art

[0002] With the development of technology, electronic pictures have become an important part of data. At present, there are only a few ways to complete the transmission of pictures between different devices: wireless communication connection (network, Bluetooth, NFC and infrared, etc.), direct cable connection, mobile storage media (U disk, etc.), and pictures displayed by direct shooting. Nowadays, smart phones generally have the hardware support required for wireless communication, so among these methods, wireless communication connection is the most convenient and commonly used. However, the current picture transmission technology still has the following problems:

[0003] 1) In a non-near-field environment, if you want to transfer pictures between two mobile phones, you must have a network, otherwise the devices cannot be interconnected to achieve the purpose of picture transmission.

[0004] 2) In a near-field environment, without the need for a network, taking pictures of the pictures displayed on the screen with a mobile phone is also one of the ways to obtain pictures. However, this method may cause stretching, deformation, occlusion, etc. of the target picture due to angle deviation, distance, occlusion, etc., thus affecting the picture quality.

[0005] 3) When multiple images are transmitted, they cannot be sent and arrive at the same time. For example, if there are 10 images that need to participate in subsequent calculations, these 10 images need to start transmitting and arrive at the same time to improve calculation efficiency.

[0006] 4) For this non-instant download method, a unique URL must be generated and the downloading party must know this URL to complete the image download.

[0007] From the above, we can see that the current image transmission technology has problems such as low image transmission efficiency and insufficient image quality when there is no network environment. Summary of the invention

[0063] The present application can be used in many general or special computer system environments or configurations. For example: personal computers, server computers, handheld or portable devices, tablet devices, multiprocessor systems, microprocessor-based systems, set-top boxes, programmable consumer electronic devices, network PCs, minicomputers, mainframe computers, distributed computing environments including any of the above systems or devices, etc. The present application can be described in the general context of computer-executable instructions executed by a computer, such as program modules.

[0065] The present invention proposes a method for wireless transmission of pictures. The method obtains the pixel RGB of a picture to be sent, generates an RGB color block of a certain size, and then regularly displays the RGB color block according to the pixel coordinates (through an electronic screen, an LED light, a video stream, etc.). The picture receiver shoots the RGB color block in real time through a camera, restores the pixel color according to the photographed RGB color block, and sequentially assigns the pixel color to the pixel position of a local blank picture, and finally completes the copy transmission of the picture; if it is necessary to send and receive multiple pictures at the same time, it is only necessary to splice the RGB color blocks of multiple pictures at the same pixel position and then regularly display them. The picture receiver shoots the spliced ​​RGB color block in real time through a camera, and restores the pixel color of each picture according to the photographed RGB color block, and sequentially assigns the pixel color to multiple local blank picture pixel positions, so as to achieve the purpose of sending and receiving multiple pictures at the same time.

[0066] like Figure 1 FIG. 1 is a flowchart of a method for wirelessly transmitting pictures provided by an embodiment of the present invention, referring to FIG. Figure 1 The embodiment of the present invention provides a method for wireless transmission of pictures, which specifically includes the following steps:

[0067] S101, determining pixel coordinate information and RGB color information of each pixel of the target image, and generating an RGB color block image of the corresponding pixel according to the RGB color information;

[0068] S102, generating color block image time series data according to pixel coordinate information and the RGB color block image, and displaying the color block image time series data through a first device;

[0069] S103, acquiring color block image time series data by shooting with a second device, and obtaining pixel coordinate information and a corresponding RGB color block image according to the color block image time series data;

[0070] S104: Determine corresponding RGB color information according to the RGB color block image, and then restore the target image according to the pixel coordinate information and the corresponding RGB color information.

[0071] It can be understood that the embodiment of the present invention records the RGB color information of each pixel of the target image through the color block image timing data, displays the color block image timing data through the first device and shoots it through the second device, so that the target image can be restored on the second device side according to the color block image timing data, and the transmission and replication of the image data can be completed without relying on traditional wired or wireless communication technology. Since only the color information of the color block image timing data at each moment needs to be captured during shooting, the size of the color block is not concerned, and the image quality will not be affected by the deviation of the shooting angle. Moreover, due to the diffraction characteristics of light, when the color block image timing data is blocked to a certain extent, the color information at each moment can also be captured to complete the image transmission, thereby improving the efficiency and image quality of image transmission in a network-free environment.

[0072] It should be noted that the RGB color block image in the embodiment of the present invention can be a large-size pure color RGB color block image obtained by directly assigning RGB colors according to RGB color information, or a red color block image, a green color block image and a blue color block image can be obtained according to the RGB color information, and then spliced ​​to obtain a large-size RGB color block image.

[0073] like Figure 2 FIG. 1 is a flowchart of step S101 provided in an embodiment of the present invention, referring to FIG. Figure 2 As an optional implementation, generating an RGB color block image of a corresponding pixel point according to the RGB color information specifically includes:

[0074] S1011, determining the red component, green component and blue component of the pixel point according to the RGB color information;

[0075] S1012, generating a red color block according to the red component, generating a green color block according to the green component, and generating a blue color block according to the blue component;

[0076] S1013, splicing the red color block, the green color block and the blue color block according to a preset splicing rule to obtain an RGB color block image.

[0077] Specifically, the pixel coordinate information (x, y) and RGB color information (r, g, b) of each pixel in the target image are obtained from top to bottom and from left to right, where x represents the number of rows of pixels, y represents the number of columns of pixels, r represents the red component of pixels, g represents the green component of pixels, and b represents the blue component of pixels. The R channel of the color block is assigned a value according to the red component r, and the G channel and the B channel are assigned a value of 0 to generate a red color block. Similarly, a green color block is generated according to the green component g, and a blue color block is generated according to the blue component b. The red color block, the green color block and the blue color block are spliced ​​according to the preset splicing rules (such as horizontal splicing, vertical splicing, fan-shaped splicing, etc.) to obtain an RGB color block image.

[0078] It can be understood that in order to improve the accuracy of the color information of the RGB color block image read by the receiving device when shooting the color block image timing data, the embodiment of the present invention generates red color blocks, green color blocks and blue color blocks representing the red component, green component and blue component respectively according to the RGB color information, and then splices them to obtain the RGB color block image. In this way, when reading the color information of the RGB color block image, the receiving device can read the R value of the red color block, the G value of the green color block and the B value of the blue color block respectively, thereby restoring the RGB color information, which is more accurate than directly reading the RGB color information of the pure color RGB color block image, so that the picture restored by the receiving device is closer to the original picture.

[0079] like Figure 3 FIG. 1 is a flow chart of step S102 provided in an embodiment of the present invention, referring to FIG. Figure 3 As an optional implementation, color block image time series data is generated according to pixel coordinate information and RGB color block image, which specifically includes:

[0080] S1021, generating a color block image time sequence segment according to the RGB color block image and a preset color block display duration;

[0081] S1024 , sorting and splicing the color block image time series segments according to the pixel coordinate information to obtain color block image time series data.

[0082] Specifically, the color block display duration of a single RGB color block image is pre-set (e.g., 30ms), and the duration of each RGB color block image is set according to the color block display duration to obtain color block image time sequence segments; the color block image time sequence segments are sorted and spliced ​​according to the pixel coordinate information obtained in the previous steps to obtain color block image time sequence data.

[0083] like Figure 4 FIG. 1 is another step flow chart of step S102 provided in an embodiment of the present invention, referring to FIG. Figure 4As an optional implementation, color block image time series data is generated according to pixel coordinate information and RGB color block image, which specifically includes:

[0084] S1022, splicing multiple RGB color block images corresponding to the same pixel coordinates of multiple target images to obtain a combined color block image;

[0085] S1023, generating a color block image time sequence segment according to the combined color block image and a preset color block display duration;

[0086] S1024 , sorting and splicing the color block image time series segments according to the pixel coordinate information to obtain color block image time series data.

[0087] Specifically, if multiple pictures are transmitted at the same time, the RGB color block images at the same pixel coordinate position of the multiple pictures are spliced ​​to obtain a combined color block image, and the duration of each combined color block image is set according to the color block display duration to obtain the color block image time sequence segments; the color block image time sequence segments are sorted and spliced ​​according to the pixel coordinate information obtained in the previous steps to obtain the color block image time sequence data.

[0088] like Figure 5 FIG. 1 is a flow chart of step S1024 provided in an embodiment of the present invention, referring to FIG. Figure 5 As an optional implementation, the color block image time series segments are sorted and spliced ​​according to the pixel coordinate information to obtain the color block image time series data, which specifically includes:

[0089] S10241, sorting the color block image sequential segments according to the pixel coordinate information, and determining whether the pixel points corresponding to the color block image sequential segments are line break pixels;

[0090] S10242, splicing the current color block image timing segment and the next color block image timing segment, if the pixel point corresponding to the next color block image timing segment is not a line break pixel point, inserting a preset pixel interval segment between the current color block image timing segment and the next color block image timing segment, if the pixel point corresponding to the next color block image timing segment is a line break pixel point, inserting a preset line break interval segment between the current color block image timing segment and the next color block image timing segment, to obtain color block image timing data.

[0091] Specifically, the color block image timing segments are sorted according to the pixel coordinate information, and it is determined whether the pixel points corresponding to each color block image timing segment are row break pixels. The color block image timing segments corresponding to the row break pixels can be marked. In addition, the color block image timing segments corresponding to the last pixel can also be marked (different from the row break pixels).

[0092] The current color block image timing segment and the next color block image timing segment are spliced. If the pixel corresponding to the next color block image timing segment is not a line break pixel, a preset pixel interval segment is inserted between the current color block image timing segment and the next color block image timing segment. If the pixel corresponding to the next color block image timing segment is a line break pixel, a preset line break interval segment is inserted between the current color block image timing segment and the next color block image timing segment. The pixel interval segment and the line break interval segment can be distinguished by different durations. For example, both the pixel interval segment and the line break interval segment are configured to display no color, but the duration of the former is 10ms and the duration of the latter is 15ms. The pixel interval segment and the line break interval segment can also be distinguished by different color block colors. For example, both the duration of the pixel interval segment and the line break interval segment are configured to be 10ms, but the color block color of the former is pure white and the color block color of the latter is pure black. In addition, the pixel interval segment and the line break interval segment can also be distinguished by different durations and color block colors at the same time.

[0093] In some optional embodiments, after the color block image timing segment corresponding to the last pixel point, an end marker segment can be spliced ​​for the receiving device to determine whether the image has been transmitted. The end marker segment can also be distinguished from the aforementioned pixel interval segment and line break interval segment based on the duration and / or color block color, which will not be elaborated here.

[0094] After obtaining the color block image timing data, the color block image timing data is displayed through the first device, which can be by displaying the color block images of the color block image timing data at each moment through a display screen, or by displaying the colors of the color block images of the color block image timing data at each moment through a light-emitting device, until all the color block image timing data are displayed.

[0095] When the user takes a photo through the second device, a special identification area can be set in the camera screen to remind the user that this area is aligned with the area currently used to display the color block image timing data, and keep the graphic area in the camera's identification area; if the color block image timing data corresponds to multiple pictures at the same time, you can also customize the addition of identification areas to match different picture positions.

[0096] like Figure 6 FIG. 1 is a flow chart of step S103 provided in an embodiment of the present invention, referring to FIG. Figure 6 As an optional implementation, pixel coordinate information and corresponding RGB color block images are obtained by parsing the color block image time series data, which specifically includes:

[0097] S1031, parsing the color block image time sequence data to obtain a plurality of color block image time sequence segments, a first interval segment, and a second interval segment;

[0098] S1032, determining that the one with a larger number of the first interval segments and the second interval segments is a pixel interval segment, and the other is a line break interval segment;

[0099] S1033, restoring pixel coordinate information according to the arrangement order of the color block image sequential segments, the pixel interval segments and the line break interval segments, and determining the RGB color block image corresponding to the pixel coordinate information according to the color block image sequential segments.

[0100] Specifically, when continuously shooting the color block image timing data, the color alternation pattern of the captured color block image timing data is identified, so as to restore the RGB color block image corresponding to the pixel coordinate information. For example, repeatedly read the first duration of 30ms for displaying the RGB color block image and the second duration of 10ms for not displaying the RGB color block image or displaying pure white / pure black in the continuous multiple frames of images. According to the duration, it can be determined that the longer duration is the first duration, and the corresponding segment is the color block image timing segment, and the shorter duration is the second duration, and the corresponding segment is the first interval segment. The recorded time length variable is A = {"long": 30ms, "short": 10ms}. At this time, there are only 2 parameters; continue to read the image, and you can get the third duration of 15ms for not displaying the RGB color block image or displaying pure white / pure black. Obviously, the third duration is 15ms. The duration will appear later than the first duration and the second duration, and its number of appearances will also be less than the first duration and the second duration. The segment corresponding to the third duration is determined to be the second interval segment, and the time length variable is updated to be A={"long": 30ms, "short": 10ms, "line break": 15ms}; continue to read the image, and a fourth duration of 25ms can be obtained that does not display the RGB color block image or displays pure white / pure black, indicating that the color block image timing data transmission is completed, and the time length variable is updated to be A={"long": 30ms, "short": 10ms, "line break": 15ms, "end point": 25ms}. At the same time, when reading the RGB color block image of the color block image timing data, it can be determined whether to jump to the next pixel point according to the pixel interval segment, and it can be determined whether to adjust the next pixel row according to the line break interval segment, so as to obtain the corresponding pixel coordinate information (x i ,y j ).

[0101] like Figure 7 FIG. 1 is a flow chart of step S104 provided in an embodiment of the present invention, referring to FIG. Figure 7 As an optional implementation, the corresponding RGB color information is determined according to the RGB color block image, and then the target image is restored according to the pixel coordinate information and the corresponding RGB color information, which specifically includes:

[0102] S1041, determining corresponding red color blocks, green color blocks, and blue color blocks according to the RGB color block image;

[0103] S1042, reading a red component according to the red color block, reading a green component according to the green color block, and reading a blue component according to the blue color block;

[0104] S1043, determining corresponding RGB color information according to the red component, the green component, and the blue component;

[0105] S1044, determining a pixel array according to the pixel coordinate information, and assigning RGB colors to each pixel point of the pixel array according to the RGB color information to obtain a target image.

[0106] Specifically, according to the recorded pixel coordinate information (x i ,y j ) generates one or more blank pixel arrays, determines the red component, green component and blue component according to the read RGB color block image, thereby obtaining the corresponding RGB color information, and assigns RGB color to each pixel point of the pixel array according to the RGB color information, so as to obtain one or more target images.

[0107] The method steps of the embodiment of the present invention are described above. It can be recognized that the embodiment of the present invention records the RGB color information of each pixel of the target image through the color block image timing data, displays the color block image timing data through the first device and shoots it through the second device, so that the target image can be restored on the second device side according to the color block image timing data, and the transmission and replication of the image data can be completed without relying on traditional wired or wireless communication technology. Since only the color information of the color block image timing data at each moment needs to be captured during shooting, the size of the color block is not concerned, and the image quality will not be affected by the deviation of the shooting angle. Moreover, due to the diffraction characteristics of light, when the color block image timing data is blocked to a certain extent, the color information at each moment can also be captured to complete the image transmission, thereby improving the efficiency and image quality of image transmission in a network-free environment.

[0108] Compared with the prior art, the embodiments of the present invention also have the following advantages:

[0109] 1) The present invention extracts the RGB of the picture pixels in sequence, simulates RGB through other carriers (LED, electronic screen, etc.) and uses them as the emitting light source, and transmits and copies them pixel by pixel to avoid problems such as picture distortion, deformation or occlusion when taking pictures in a network-free environment.

[0110] 2) The present invention can parse and obtain key information such as target pixel RGB and picture ranks according to the switching duration of different color segments, thereby reducing the minimum transmission granularity, overcoming the current defect that the picture as a whole has rigid requirements on the network when being transmitted, and avoiding problems such as picture transmission interruption and picture reception failure caused by network fluctuations or disconnection.

[0111] 3) The present invention can transmit multiple pictures at the same time and receive multiple pictures at the same time, avoiding the defects of the current traditional means of transmitting different pictures at the same time due to problems such as network, picture format, picture size, etc.
