Abstract

The invention relates to a tile publishing method and device, electronic equipment and a computer readable storage medium. In the process of publishing the tiles corresponding to the original image, the to-be-published tiles are selected from all the tiles, then the data information of the to-be-published tiles is extracted, and the metadata management table is generated according to the data information and published to the server to complete the publishing operation. In the process, only the metadata management table formed by the data information of the tiles needs to be published, and thedata volume of the metadata management table is far smaller than that of the images, so that compared with a mode of publishing the images in the prior art, the data volume transmitted to the server is reduced, and the publishing time is correspondingly shortened. Moreover, the data volume transmitted to the server is reduced, so that the requirement on the storage space of the server is reduced,and the problem of publishing failure possibly caused by insufficient storage space of the server is avoided.

Example Embodiment

[0065] Of course, it is worth pointing out that the original images mentioned above are all global original images with consistent specifications. However, in the actual shooting process, the original image that may be obtained is only the original image of a certain area at a certain shooting time. In this embodiment, when the original image is segmented, the acquired original image is first compared with the global original image, so as to obtain the range of the original image in the global original image that is segmented according to the preset level Value (the distribution range of the row number and the distribution range of the column number); then, according to the obtained range value and the preset level, the original image is segmented according to the TMS standard, and finally, the original image is relative to the global The range in the original image is named and archived for the tiles obtained after segmenting the original image. Specifically, after the division is completed, a shooting time folder corresponding to the shooting time of the original image is created, a Z folder corresponding to the level of the original image is created, and an X folder corresponding to the number of rows of the original image is created , And save the corresponding tiles as Y files.
[0066] At this time, if you shoot for different regions at the same shooting time, for example, shoot the original images of geographically discontinuous regions 1 and 2 at the same time point to obtain the original image 1 and the original image 2, then For the original image 1 and the original image 2, since the shooting time is the same, the tiles corresponding to the original image 1 and the original image 2 can be stored in the same shooting time folder to facilitate management. In order to further facilitate management, assuming that the original image 1 and original image 2 are divided into the same preset level, the tiles corresponding to the original image 1 and the original image 2 should belong to the same shooting time folder The same Z folder. Then, under the same preset level, the original image 1 and original image 2 corresponding to the geographically discontinuous area 1 and area 2 have different range values ​​in the global original image, resulting in the same The folder name of the X folder under the Z folder may be discontinuous, and the file name of the Y file under the same X folder under the same Z folder may be discontinuous. For example, suppose that original image 1 corresponds to figure 2 The global raw image shown ( figure 2 The level Z in is the abef area in 2). It is assumed that when the original image 2 is compared with the global original image, it corresponds to figure 2 The klop area in the global original image shown. Because the row number of the abef area in the global original image is between 1-2 and the column number is between 1-2; the row number of the klop area in the global original image is between 3-4 and the column number is 3-4 Correspondingly, when the original image 1 is divided according to the preset level (Z=2), the range of tiles obtained is: the row number is between 1-2 and the column number is between 1-2 ; When the original image 2 is segmented according to a preset level (Z=2), the range of tiles obtained is: the row number is between 3-4 and the column number is between 3-4.
[0067] The following will combine Figure 4 The shown process introduces the tile publishing method provided in the embodiment of the present application. The method may include the following steps.
[0068] Step S110: Determine the tile to be released from all the tiles corresponding to the original image.
[0069] After determining the original image, and the tiles corresponding to the original image follow the above image 3 After the storage method shown is saved, the tile corresponding to the original image can be published.
