Description

Technical Field

[0001] This application relates to the field of computer application technologies, and particularly to an image transmission method, apparatus, computer device, and storage medium. Background Art

[0002] In the engineering field, a server storing engineering design drawings often receives an image browsing request sent by a client.

[0003] In the traditional technology, the server transmits the image to the client according to the image browsing request. Since the files of engineering drawings are usually large, the transmission takes a long time. It should be noted that a large engineering drawing is usually completed through the division of labor and cooperation of multiple users in multiple departments. The user who sends the image browsing request using the client usually only cares about the image in a part of the drawing area. Since the user can view the area of interest in the drawing only after downloading all the information of the entire drawing, the waiting time for the user to view the area of interest is relatively long in the traditional image transmission method.

[0004] Therefore, how to improve the image transmission method to shorten the image transmission duration and reduce the waiting duration when the client displays the image is a technical problem to be solved urgently. Summary of the Invention

[0068] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0069] Please refer to Figure 1A , Figure 1AIt is a schematic diagram of an application scenario of an image transmission method provided by an embodiment of the present application, including a first terminal 101 and a second terminal 102. As shown in FIG. 1, when performing image transmission, the first terminal 101 acts as a client. When a user hopes to clearly view a specified sub-region in the target image on the display interface of the first terminal 101, the first terminal 101 can send an image transmission request to the second terminal 102. The image transmission request carries image identification information and identification information related to the specified sub-region; the target image is determined according to the image identification information, and the target image includes multiple sub-regions. The second terminal 102 determines the specified sub-region from the multiple sub-regions according to the identification information related to the specified sub-region; in response to the image transmission request, the second terminal 102 sends the image information corresponding to the specified sub-region to the first terminal 101 in a full-volume transmission mode, and sends the image information corresponding to the other sub-regions other than the specified sub-region in the target image to the first terminal 101 in a component transmission mode; wherein, the full-volume transmission mode refers to a transmission mode in which the image information corresponding to all pixel points of the image to be transmitted is sent; the component transmission mode refers to a transmission mode in which a part of the image information corresponding to all pixel points of the image to be transmitted is sent.

[0070] After receiving the image information, the client can perform synchronous display. When using this image transmission method, the sub-region that the user is interested in and hopes to clearly view can be determined as the specified sub-region. Since the specified sub-region is transmitted in a full-volume transmission mode and the other sub-regions are transmitted in a component transmission mode during image transmission, the amount of data transmitted is reduced, the transmission time is shortened, the transmission efficiency is improved, and the user's need to clearly view the specified sub-region through the client is satisfied, thus improving the user experience.

[0071] For example, in Figure 1A the scenario shown for image transmission, the target image is as Figure 1B shown. If region A in the target image is the specified sub-region, the image transmission request carries the identification information of the image as Figure 1B shown. This identification information can be the name of the image or the serial number of the image, etc., and the identification information of region A. For example, different sub-regions in Figure 1B can be identified by different coding information. For example, region A can be identified by code 001. In response to the image transmission request, when the second terminal 102 sends the target image, only region A in the target image is transmitted in full volume. If Figure 1B regions A and B in the target image shown are the specified sub-regions, the image transmission request carries the identifications of regions A and B. When the second terminal 102 transmits the target image to the first terminal 101, only regions A and B in the target image are transmitted in full volume.

[0072] In a possible implementation, the image information sent by the second terminal 102 to the first terminal 101 may include the size of the target image and the coordinates of each sub-region in the target image. The first terminal 101 can display the images corresponding to each sub-region at the relative positions of the sub-regions in the target image according to the received image information.

[0073] In some possible implementations, in order to further reduce the amount of transmitted information, when transmitting the non-designated sub-regions in the target image, the digital information corresponding to the non-designated sub-regions may not be sent to the first terminal 101 either. When the first terminal 101 displays the target image, it can clearly display the designated sub-regions according to the received image information of the designated sub-regions transmitted in the full-volume transmission mode, and the areas corresponding to the non-designated sub-regions may be displayed as blank, or displayed as mosaics or related images with poor clarity. By adopting this implementation, it not only meets the user's need to clearly view specific sub-regions, but also reduces the amount of transmitted information, shortens the transmission duration, and reduces the waiting time for the user to view pictures.

[0074] In some possible implementations, after the first terminal 101 views the designated sub-region, if it needs to further view at least one other sub-region, the first terminal 101 can send image request information including the identifiers of the other sub-regions to be viewed to the second terminal 102. The second terminal 102 can also determine whether the user corresponding to the user identifier has the permission to view the sub-region corresponding to the sub-region identifier specified in the image transmission request according to the user identifier information carried in the image transmission request.

[0075] In a possible implementation, when the component transmission mode is adopted for transmitting the non-designated sub-regions in the target image, the image information corresponding to the non-designated sub-regions can be sent in a certain proportion. For example, if the non-designated sub-region includes 1000 pixels, the digital information of 100 of them can be randomly sent. In some possible implementations, when there are multiple non-designated sub-regions, when transmitting the image information corresponding to the non-designated sub-regions, different non-designated sub-regions can transmit a part of all the digital information according to different weight values. The closer to the designated sub-region, the greater the weight value, and the weight value is positively correlated with the amount of transmitted information. By adopting this implementation for data transmission, by setting the weight value, for example, the weight value corresponding to the sub-region farther from the designated sub-region is set smaller, when the client displays the target image, it can be realized that the image corresponding to the sub-region closer to the designated sub-region is clearer, and the image corresponding to the sub-region farther from the designated sub-region is blurrier. By adopting this implementation, by setting the weight value, it not only meets the user's need to clearly view specific sub-regions, but also can set the weight values corresponding to adjacent and farther sub-regions according to needs to meet different viewing requirements.

[0076] Please refer to Figure 2 , which is a schematic flowchart of an image transmission method provided by an embodiment of the present application. As Figure 2 shown, the image transmission method includes steps 201 to 204, where:

[0077] 201. Obtain an image transmission request sent by a client, where the image transmission request carries image identification information and identification information related to a specified sub-region.

[0078] For example, the image transmission request may carry Figure 1B the identification of the image shown.

[0079] In some possible implementation manners, the identification information related to the specified sub-region includes a user identification or a set of selected sub-region identifications.

[0080] 202. Determine a target image according to the image identification information, where the target image includes multiple sub-regions.

[0081] 203. Determine the specified sub-region from the multiple sub-regions according to the identification information related to the specified sub-region.

[0082] In some possible implementation manners, the identification information related to the specified sub-region includes: a user identification; the specified sub-region can be determined based on a preset sub-region browsing rule and the user identification; the preset sub-region browsing rule includes: the correspondence between the user identification and the set of sub-region identifications corresponding to the user browsing permission. For example, if two user identifications are set in the preset sub-region browsing rule: user 001 and user 002, the set of sub-region identifications corresponding to user 001 includes region A and region B, and the set of sub-region identifications corresponding to user 002 includes region C and region D. If the identification information related to the specified sub-region carried in the image transmission request is the user identification: user 001, then according to the preset sub-region browsing rule, the specified sub-region to be determined includes: region A and region B. If the identification information related to the specified sub-region carried in the image transmission request is the user identification: user 002, then according to the preset sub-region browsing rule, the specified sub-region to be determined includes: region C and region D.

[0083] In some possible embodiments, the identification information related to the specified sub-region includes: a set of selected sub-region identifiers; the set of selected sub-region identifiers can be at least one sub-region selected by the user through the client within the range of the sub-region set corresponding to the user's permissions; the specified sub-region is determined from multiple sub-regions based on the set of selected sub-region identifiers. For example, if the browsing permission of the user with the user identifier of user 001 is Image A and Image B, and user 001 hopes to view the corresponding image of Image A, then the identifier corresponding to Image A can be selected within its permission range, and the identifier corresponding to Image A is the set of selected sub-region identifiers. It can be understood that the set of selected sub-region identifiers can be one or more, which is specifically set according to the actual situation and is not limited here.

[0084] 204. In response to an image transmission request, send the image information corresponding to the specified sub-region to the client in a full-volume transmission manner, and send the image information corresponding to other sub-regions outside the specified sub-region in the target image to the client in a component transmission manner.

[0085] Among them, the full-volume transmission manner refers to a transmission manner in which all the image information corresponding to all the pixel points of the image to be transmitted is sent. For example, if the image to be transmitted includes 1000 pixel points, the full-volume transmission is to send all the image information corresponding to all 1000 pixel points of the image to be transmitted to the client. The image information can include RGB values, brightness information, etc. The parameter attributes included in the image information can also include other parameters, which can be set according to needs and are not limited here; the component transmission manner refers to a transmission manner in which a part of the image information corresponding to all the pixel points of the image to be transmitted is sent. For example, if the image to be transmitted includes 1000 pixel points, the full-volume transmission is to send all the image information corresponding to all 1000 pixel points of the image to be transmitted to the client.

[0086] When using this embodiment for image transmission, the server, in response to the target image transmission instruction, sends the digital information corresponding to the target image to the client and only performs full-volume transmission on the specified sub-region. Since only full-volume transmission is performed on the specified sub-region, compared with the prior art, the amount of data transmitted during image transmission is reduced. Therefore, the duration of transmitting the image is shortened. Correspondingly, the waiting duration when the client displays the target image is also shortened.

[0087] Please refer to Figure 3 , which is a schematic flowchart of an image transmission method provided by another embodiment of the present application. As Figure 3 shown, the image transmission method includes steps 301 to 305, where:

[0088] 301. Obtain an image transmission request sent by the client. The image transmission request carries image identification information and identification information related to a specified sub-region.

[0089] For example, the image transmission request may carry Figure 1B the identification of the image shown.

[0090] In some possible implementation manners, the identification information related to the specified sub-region includes a user identification or a set of selected sub-region identifications.

[0091] 302. Determine a target image according to the image identification information. The target image includes multiple sub-regions.

[0092] 303. Determine the specified sub-region from the multiple sub-regions according to the identification information related to the specified sub-region.

[0093] In some possible implementation manners, the identification information related to the specified sub-region includes: a user identification; the specified sub-region can be determined based on a preset sub-region browsing rule and the user identification; the preset sub-region browsing rule includes: the correspondence between the user identification and the set of sub-region identifications corresponding to the user's browsing permissions. For example, if two user identifications are set in the preset sub-region browsing rule: user 001 and user 002, the set of sub-region identifications corresponding to user 001 includes region A and region B, and the set of sub-region identifications corresponding to user 002 includes region C and region D. If the identification information related to the specified sub-region carried in the image transmission request is the user identification: user 001, then according to the preset sub-region browsing rule, the specified sub-region to be determined includes: region A and region B. If the identification information related to the specified sub-region carried in the image transmission request is the user identification: user 002, then according to the preset sub-region browsing rule, the specified sub-region to be determined includes: region C and region D.

[0094] In some possible implementation manners, the identification information related to the specified sub-region includes: a set of selected sub-region identifications; the set of selected sub-region identifications can be at least one sub-region selected by the user through the client within the range of the set of sub-regions corresponding to the user's permissions; the specified sub-region is determined from the multiple sub-regions based on the set of selected sub-region identifications. For example, if the user 001's browsing permission is image A and image B, and user 001 hopes to view the corresponding image of image A, then the user can select the identification corresponding to image A within its permission range, and the identification corresponding to image A is the set of selected sub-region identifications. It can be understood that the set of selected sub-region identifications can be one or more, which is specifically set according to the actual situation and is not limited here.

[0095] 304. Determine the transmission priorities of other sub-regions in the target image except the specified sub-region according to the weight values respectively corresponding to the other sub-regions in the target image except the specified sub-region.

[0096] For example, the weight values respectively corresponding to the other sub-regions except the specified sub-region can be set in advance. For instance, if the target image includes Region A, Region B, Region C, and Region D, and Region A is the specified sub-region, and the weight values respectively corresponding to Region B, Region C, and Region D are 0.8, 0.7, and 0.6, then the priorities from high to low are: Region B, Region C, and Region D.

[0097] 305. In response to an image transmission request, send the image information corresponding to the specified sub-region to the client in a full-volume transmission manner, and send the image information corresponding to the other sub-regions to the client in a component transmission manner in sequence according to the transmission priorities.

[0098] Among them, the full-volume transmission manner refers to a transmission manner in which the image information corresponding to all pixel points of the image to be transmitted is sent. For example, if the image to be transmitted includes 1000 pixel points, then the full-volume transmission is to send the image information corresponding to all 1000 pixel points of the image to be transmitted to the client. The image information can include RGB values, brightness information, etc. The parameter attributes included in the image information can also include other parameters, which can be set according to needs and are not limited here; the component transmission manner refers to a transmission manner in which a part of the image information corresponding to all pixel points of the image to be transmitted is sent. For example, if the image to be transmitted includes 1000 pixel points, then the full-volume transmission is to send the image information corresponding to all 1000 pixel points of the image to be transmitted to the client.

[0099] Taking the example in step 304, for instance, if the target image includes Region A, Region B, Region C, and Region D, and Region A is the specified sub-region, and the weight values respectively corresponding to Region B, Region C, and Region D are 0.8, 0.7, and 0.6, then the priorities from high to low are: Region B, Region C, and Region D. Then when transmitting the image information to the client, send the image information corresponding to Region A to the client in a full-volume transmission manner, and then send the image information corresponding to each region to the client in a component transmission manner in the order of Region B, Region C, and Region D. If Region B, Region C, and Region D include 1000 pixel points, then when transmitting the image information corresponding to Region B, Region C, and Region D, the image information corresponding to 800 pixel points of Region B can be transmitted in a component transmission manner first, then the image information corresponding to 700 pixel points of Region C can be transmitted in a component transmission manner, and finally the image information corresponding to 600 pixel points of Region D can be transmitted in a component transmission manner.

[0100] In some possible embodiments, the client can display in real time according to the received image information. After receiving the image information corresponding to the specified sub-region, the image corresponding to the specified sub-region is preferentially displayed, and then the transmission order of the image information of other sub-regions is determined according to the weight values corresponding to the other sub-regions respectively. The weight value can be determined according to the distance between the other sub-region and the specified sub-region. The smaller the weight value corresponding to the sub-region that is farther from the specified sub-region.

[0101] When using this embodiment for image transmission, the image information corresponding to the specified sub-region is preferentially sent, and then the image information corresponding to each of the other sub-regions is sent according to the priority. This is beneficial for the client to view the image corresponding to the specified sub-region first. Since only the full amount of data is transmitted for the specified sub-region, compared with the prior art, the amount of data transmitted during image transmission is reduced. Therefore, the time taken to transmit the image is shortened. Correspondingly, the waiting time for the client to display the target image is also shortened.

[0102] Please refer to Figure 4 , which is a schematic flowchart of an image transmission method provided by another embodiment of the present application. As Figure 4 shown, the image transmission method includes steps 401 to 408, where: steps 401 to 403 are similar to steps 301 to 303. For simplicity, they will not be described here again. For details, please refer to the description of steps 301 to 303 above.

[0103] 404. Detect the network transmission quality.

[0104] 405. Determine whether the network transmission quality is lower than the preset value. If not, execute step 406. If so, execute steps 407 and 408.

[0105] 406. In response to the image transmission request, send the image information corresponding to the specified sub-region to the client in a full-volume transmission mode, and send the image information corresponding to the other sub-regions outside the specified sub-region in the target image to the client in a component transmission mode.

[0106] 407. Adjust the weight values corresponding to each of the other sub-regions outside the specified sub-region in the target image according to the preset weight value adjustment strategy.

[0107] For example, if the target image includes region A, region B, region C, and region D, region A is the specified sub-region, and the weight values corresponding to region B, region C, and region D are 0.8, 0.7, and 0.6 respectively, then the priorities from high to low are: region B, region C, and region D. When the network transmission quality is lower than the threshold, the weight values corresponding to region B, region C, and region D are successively adjusted to 0.5, 0.3, and 0.1.

[0108] 408. In response to an image transmission request, the image information corresponding to a specified sub-region is sent to the client in a full-volume transmission manner, and the image information corresponding to other sub-regions outside the specified sub-region in the target image is sent to the client in a component transmission manner.

[0109] For example, when transmitting image information to the client, the image information corresponding to region A is sent to the client in a full-volume transmission manner, and then the image information corresponding to each of regions B, C, and D is sent to the client in a component transmission manner in the order of region B, region C, and region D. If regions B, C, and D include 1000 pixel points, then when transmitting the image information corresponding to regions B, C, and D, the image information corresponding to 500 pixel points in region B can be transmitted first in a component transmission manner, then the image information corresponding to 300 pixel points in region C can be transmitted in a component transmission manner, and finally the image information corresponding to 100 pixel points in region D can be transmitted in a component transmission manner.

[0110] When performing image transmission using this embodiment, when the network transmission quality is lower than the threshold, the weight values corresponding to other sub-regions outside the specified sub-region are lowered, which can further reduce the amount of data transmitted during image transmission and is beneficial to further shortening the duration of transmitting the image. Correspondingly, the waiting duration when the client displays the target image is also shortened.
