DETAILED DESCRIPTION

[0012] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0013] See also Figure 1 , which shows a flow chart of an image data transmission method for map drawing of the present application.

[0014] like Figure 1 As shown, the image data transmission method for map drawing specifically includes the following steps: Step S101, acquiring a mapped image, and preprocessing the mapped image based on a preset image recognition model to obtain a target sub-image and at least one first mapped sub-image corresponding to the target sub-image, wherein the target sub-image only includes an unmapped area, and the first mapped sub-image includes a mapped area and an unmapped area.

[0015] In this step, the mapped image is input into a preset image recognition model, and the image recognition model outputs the mapped pixel points corresponding to the mapped image, determines the maximum circumscribed rectangle of each mapped pixel point, and uses a sliding window of a preset size to slide on the maximum circumscribed rectangle of each mapped pixel point, and merges the area covered by the sliding window with the maximum circumscribed rectangle to obtain the first mapped sub-image of the mapped area and the unmapped area, and captures each first mapped sub-image in the mapped image to obtain the target sub-image.

[0016] It should be noted that the image recognition model may be a model obtained by iteratively training the mapped image and the annotations of the mapped image into a neural network, and the neural network may be a VGGNet network or other convolutional neural networks.

[0017] Step S102: extracting target coordinate information of target pixels in the target sub-image according to a preset two-dimensional coordinate system.

[0018] In this step, the target sub-image is placed in the first quadrant of the two-dimensional coordinate system, and the first edge and the second edge of the target sub-image are overlapped with the X-axis and the Y-axis of the two-dimensional coordinate system respectively, wherein the first edge and the second edge are adjacent; after the setting is completed, the target coordinate information of the target pixel point in the target sub-image in the two-dimensional coordinate system is obtained.

[0019] Step S103: determining whether at least two first plotted sub-images contain an overlapping area.

[0020] In a specific embodiment, if at least two first drawn sub-images do not contain overlapping areas, the third coordinate information of at least one first drawn sub-image is directly extracted according to the two-dimensional coordinate system; the third coordinate information and the target coordinate information are associated based on a preset association strategy to obtain a third association relationship of at least one first drawn sub-image.

[0021] Step S104: if the at least two first plotted sub-images contain overlapping areas, the at least two first plotted sub-images are fused based on a preset fusion rule to obtain at least one second plotted sub-image.

[0022] In this step, if a certain first drawn sub-image contains an overlapping area with another first drawn sub-image, the certain first drawn sub-image and the other first drawn sub-image are deduplicated based on at least two pixels in the overlapping area; the maximum circumscribed rectangular area of ​​the certain first drawn sub-image and the other first drawn sub-image after deduplication is determined, and an image containing only the maximum circumscribed rectangular area is intercepted from the mapped image to obtain a fused second drawn sub-image and an updated target sub-image, wherein the updated target sub-image does not contain a certain second drawn sub-image.

[0023] Step S105, extracting the first coordinate information of the first target pixel point in the at least one second mapped sub-image according to the two-dimensional coordinate system, and extracting the second coordinate information of the second target pixel point in other first mapped sub-images, wherein the other first mapped sub-images are unfused first mapped sub-images in the at least one first mapped sub-image.

[0024] In this step, at least one second plotted sub-image is placed in the first quadrant of the two-dimensional coordinate system, and the first edge and the second edge of the at least one second plotted sub-image are overlapped with the X-axis and the Y-axis of the two-dimensional coordinate system respectively, wherein the first edge and the second edge are adjacent; after the setting is completed, the first coordinate information of the first target pixel point in the at least one second plotted sub-image in the two-dimensional coordinate system is obtained; other first plotted sub-images are placed in the first quadrant of the two-dimensional coordinate system, and the first edge and the second edge of the other first plotted sub-images are overlapped with the X-axis and the Y-axis of the two-dimensional coordinate system respectively, wherein the first edge and the second edge are adjacent; after the setting is completed, the second coordinate information of the second target pixel point in the other first plotted sub-images in the two-dimensional coordinate system is obtained.

[0025] Step S106, respectively associating the first coordinate information with the target coordinate information, and associating the second coordinate information with the target coordinate information, to obtain a first association relationship of the at least one second plotted sub-image and a second association relationship of the other first plotted sub-images.

[0026] Step S107 : transmitting the first association relationship, the second association relationship, the target sub-image, the at least one second plotted sub-image, and the other first plotted sub-images based on a preset transmission rule.

[0027] In this step, the first association relationship and the second association relationship are stored in a preset association relationship library, the target sub-image is stored in a preset first image library, and at least one second mapped sub-image and other first mapped sub-images are stored in a preset second image library; based on a preset time interval, the data in the association relationship library, the first image library and the second image library are respectively transmitted at intervals.

[0028] For example, after the mapped image A is processed through steps S101 to S106, the first association relationship a1, the second association relationship a2, the target sub-image a3, the second mapped sub-image a4 and other first mapped sub-images a5 are obtained; after the mapped image B is processed through steps S101 to S106, the first association relationship b1, the second association relationship b2, the target sub-image b3, the second mapped sub-image b4 and other first mapped sub-images b5 are obtained.

[0029] The first association relationship a1 and the second association relationship a2 are stored in a first association relationship sub-library in the association relationship library, and the first association relationship b1 and the second association relationship b2 are stored in a second association relationship sub-library in the association relationship library; The target sub-image a3 is stored in a first image sub-library in the first image library, and the target sub-image b3 is stored in a second image sub-library in the first image library; The second plotted sub-image a4 and other first plotted sub-images a5 are stored in the first image target sub-library in the second image library, and the second plotted sub-image b4 and other first plotted sub-images b5 are stored in the second image target sub-library in the second image library.

[0030] Based on the preset time interval, the first association relationship sub-library, the second association relationship sub-library, the first image sub-library, the second image sub-library, the first image target sub-library and the second image target sub-library are uploaded to the transmission queue, and each data is transmitted in sequence based on the transmission queue, thereby completing the transmission of the entire data. Specifically, the time interval for uploading the association relationship library is 10S, the time interval for uploading the first image library is 5S, and the time interval for uploading the second image library is 15S. That is, the sorting result of the data in the transmission queue can be, but is not limited to: first image sub-library-first association relationship sub-library-first image target sub-library-second image sub-library-second association relationship sub-library-second image target sub-library.

[0031] In this embodiment, the uploaded data can be disrupted by the transmission rule, so as to avoid being stolen by others during the transmission process as much as possible. Others can restore the target sub-image, at least one second plotted sub-image corresponding to the target sub-image, and other first plotted sub-images according to the transmission time, thereby effectively improving the security of image transmission containing plotted information.

[0032] In summary, the method of the present application extracts target coordinate information of target pixels in a target sub-image according to a preset two-dimensional coordinate system, extracts first coordinate information of a first target pixel in at least one second mapped sub-image according to the two-dimensional coordinate system, and extracts second coordinate information of a second target pixel in other first mapped sub-images, and associates the first coordinate information with the target coordinate information, and the second coordinate information with the target coordinate information, respectively, to obtain a first association relationship of at least one second mapped sub-image and a second association relationship of other first mapped sub-images. By setting association rules through a two-dimensional coordinate system, the complexity of the association rules can be reduced as much as possible, and by associating numbers (target coordinates) with numbers (first coordinates, first coordinates), the amount of data transmission contained in the association rules during the transmission process can be reduced as much as possible. Moreover, by transmitting the first association relationship, the second association relationship, the target sub-image, at least one second mapped sub-image, and other first mapped sub-images based on the preset transmission rules, the security of image transmission containing mapping information can be improved as much as possible.
