Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The image uploading method provided by the application can be applied to the application environment shown in fig. 1. Wherein the terminal 102 and the server 104 communicate via a network. The terminal 102 compresses the initial picture file to obtain a picture to be uploaded, starts a background task in a weak network environment to detect the network state of the terminal in real time, and automatically transmits the picture to be uploaded to the server 104 when the network state is good. The terminal 102 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the server 104 may be implemented by an independent server or a server cluster formed by a plurality of servers.
In an embodiment, as shown in fig. 2, a method for uploading a picture is provided, which is described by taking the method as an example for being applied to the terminal in fig. 1, and includes the following steps:
step 202, compressing the initial picture to obtain a picture to be uploaded;
the initial picture is a picture file selected by the terminal, and the picture to be uploaded is a picture file which is processed by the terminal and is ready to be transmitted to the server.
Specifically, the initial picture selected by the terminal may be obtained by the terminal in real time, for example, by shooting, or may be selected by the terminal from a local file, or may be selected by the terminal in another manner. And the terminal compresses the initial picture so as to reduce the memory space occupied by the picture, thereby obtaining the picture to be uploaded to the server.
Step 204, acquiring a first network state parameter of the terminal;
the first network state parameter is determined by the network state of the terminal and a preset parameter value, and can be used for judging the network state of the terminal.
Specifically, the terminal determines a first network state parameter according to the network state where the terminal is located and a preset parameter value. In one embodiment, the network status of the terminal may be monitored, and when the network status changes, it is determined whether the current network status is good.
Step 206, when the first network state parameter does not meet the preset network condition, starting a background timing task;
the preset network condition is a preset standard for judging that the network state is good.
Specifically, when the network condition reflected by the first network state parameter is poor, the terminal starts a background timing task. In one embodiment, when the terminal is connected to the network of the first standard, a background task is started. The first standard network may include a 2G network (the 2nd generation mobile communication technology network, second generation mobile communication technology network) and a 3G network (the 3rd generation mobile communication technology network, third generation mobile communication technology network).
In one embodiment, before starting the background timing task in step 206, the method further includes: and temporarily storing the picture to be uploaded.
Specifically, before the terminal starts a background task to detect the real-time network state at regular time, the picture to be uploaded is temporarily stored in the local. When the current network condition is poor, the pictures to be uploaded are stored locally, and the pictures to be uploaded are uploaded after the good network state is detected, so that the dependence of the operation flow on the network state is reduced.
the second network state parameter is determined by the network state of the terminal and a preset parameter value, and can be used for judging the network state of the terminal.
Specifically, the terminal may detect the real-time network state at a background timing, and obtain the second network state parameter according to the network state of the terminal and a preset parameter value.
In one embodiment, step 208 may include: acquiring a time parameter; and when the time parameter is within a preset time range, obtaining a second network state parameter. For example, the network status is detected every a preset time, wherein the size of the preset time can be set according to the actual situation, for example, the preset time is 30 minutes. The background task detects the network state at regular time, which not only ensures the efficient completion of the uploading task, but also does not block the system process to a large extent.
And 210, uploading the picture to be uploaded when the second network state parameter meets the preset network condition.
Specifically, when the second network state parameter is good relative to the network condition reflected by the preset requirement, the terminal transmits the picture to be uploaded to the server. In one embodiment, when the terminal is connected to the network of the second standard, the terminal transmits the picture to be uploaded to the server. The second-standard network may include a 4G network (the 4th generation mobile communication technology network, fourth generation mobile communication technology network) and a WI-FI wireless network.
In the picture uploading method, the picture file is compressed, so that the memory occupied by the picture is reduced, the storage space is saved, and the picture uploading process is accelerated; the network state of the terminal is automatically detected, so that the dependence of operation on network conditions is reduced; when the network condition is poor, a background task is started to detect the real-time network state at regular time, and when the network state is good, the background realizes automatic picture uploading, so that the main service flow is not blocked, and the waiting time of service personnel is greatly reduced. Therefore, even in unstable network conditions or poor network environments, the method can be used for efficiently executing the operation flow under the condition that service personnel hold the low-configuration equipment.
In an embodiment, the method for uploading a picture, after step 204, may further include: and when the first network state parameter meets the preset network condition, uploading the picture to be uploaded.
Specifically, when the first network state parameter is good relative to the network condition reflected by the preset requirement, the terminal transmits the picture to be uploaded to the server. In one embodiment, when the terminal is connected to the network of the third standard, the terminal transmits the picture to be uploaded to the server. The third-standard network may include a 4G network (the 4th generation mobile communication technology network, fourth generation mobile communication technology network) and a WI-FI wireless network.
According to the technical scheme, the terminal judges the network state where the terminal is located, and directly uploads the picture when the network condition is good, so that time is saved, and the operation flow of uploading the picture is efficiently, quickly and smoothly executed.

Wherein the quality compression is a compression method for reducing a picture file by reducing the quality of a picture; the sampling rate compression is a compression method for reducing the memory occupied by the picture by setting the sampling rate and reducing the pixels of the picture.
In one embodiment, the compressing the initial picture by combining the quality compression and the sampling rate compression to obtain the picture to be uploaded includes: and compressing the initial picture according to the preset quality compression parameters and the predetermined sampling rate value to obtain the picture to be uploaded.
In one embodiment, the compressing an initial picture according to a preset quality compression parameter and a predetermined sampling rate value to obtain a picture to be uploaded includes: performing quality compression on the initial picture according to the quality compression parameters to obtain a first intermediate compression result, and performing sampling rate compression on the first intermediate compression result according to the sampling rate value to obtain a picture to be uploaded; or, performing sampling rate compression on the initial picture according to the sampling rate value to obtain a second intermediate compression result, and performing quality compression on the second intermediate compression result according to the quality compression parameter to obtain the picture to be uploaded.
In one embodiment, the above sample rate compression on the initial picture or the first intermediate compression result includes, as shown in fig. 3:
step 302, calculating the aspect ratio of a sampling rate compression object;
the sampling rate compression object is the initial picture or the first intermediate compression result.
Specifically, the terminal obtains a short-edge pixel value and a long-edge pixel value of the sampling rate compression object, and then calculates a value obtained by dividing the short-edge pixel value by the long-edge pixel value, namely the aspect ratio of the sampling rate compression object.
Step 304, determining a target aspect ratio interval where the aspect ratio of the sampling rate compression object is located according to the aspect ratio of the sampling rate compression object and a preset aspect ratio numerical interval;
specifically, the terminal determines an aspect ratio value section in which the aspect ratio of the target of sample rate compression is located, based on the calculated aspect ratio of the target of sample rate compression and a preset aspect ratio value section, thereby specifying a target aspect ratio section.
specifically, the terminal determines a sampling rate value corresponding to the target aspect ratio interval, or determines a sampling rate value corresponding to the target aspect ratio interval and the long-edge pixel value of the sampling rate compression target. Wherein, the corresponding relationship is preset.
And 308, carrying out sampling rate compression processing on the initial picture according to the sampling rate value.
Specifically, the terminal reduces the pixels of the picture according to the sampling rate value, so that the memory occupied by the picture is reduced.
According to the technical scheme, the actual conditions of the compression objects with different sampling rates are considered, different sampling rate values are selected according to specific conditions, the compression quality of different picture files is guaranteed to a certain extent, and the distortion is prevented from being serious after the picture is compressed.
In one embodiment, step 306 may include the steps of: when the target aspect ratio interval is a preset first aspect ratio interval and the long-edge pixel value of the sampling rate compression object is in the preset first pixel interval, determining the sampling rate value of the sampling rate compression as a first sampling rate; when the target aspect ratio interval is a first aspect ratio interval and the long-edge pixel value of the sampling rate compression object is in a preset second pixel interval, determining the sampling rate value of the sampling rate compression as a second sampling rate; when the target aspect ratio interval is a first aspect ratio interval and the long-edge pixel value of the sampling rate compression object is in a preset third pixel interval, determining the sampling rate value of the sampling rate compression to be a third sampling rate; when the target aspect ratio interval is the first aspect ratio interval and the long-edge pixel value of the sampling rate compression object is in the preset fourth pixel interval, determining the sampling rate value of the sampling rate compression as the long-edge pixel value of the sampling rate compression object multiplied by the first preset proportion value; when the target aspect ratio interval is a preset second aspect ratio interval, determining a sampling rate value of sampling rate compression as a long-edge pixel value of a sampling rate compression object multiplied by a second preset proportion value; and when the target aspect ratio interval is a preset third aspect ratio interval, determining that the sampling rate compressed sampling rate value is the aspect ratio of the long-edge pixel value of the sampling rate compressed object multiplied by a third preset proportion value and then multiplied by the sampling rate compressed object.
In this embodiment, three aspect ratio intervals are divided, and when the aspect ratio value of the sampling rate compression target is within a specific range, different sampling rate values are further selected according to the long-side pixel value thereof. Therefore, the technical scheme sets the classification range of multiple intervals and multiple gradients according to the characteristic parameters of the pictures, so that the method and the device can be applied to various picture files with different aspect ratios and different lengths, and ensure the compression quality to a certain extent.
In one embodiment, the lower threshold of the first aspect ratio section is equal to the upper threshold of the second aspect ratio section, and the lower threshold of the second aspect ratio section is equal to the upper threshold of the third aspect ratio section; the upper threshold of the first pixel interval is equal to the lower threshold of the second pixel interval, the upper threshold of the second pixel interval is equal to the lower threshold of the third pixel interval, and the upper threshold of the third pixel interval is equal to the lower threshold of the fourth pixel interval. For example, in one embodiment, the terminal sets the first aspect ratio section to [1,0.5625], the second aspect ratio section to [0.5625,0.5], the third aspect ratio section to [0.5,0], and further, in one embodiment, the terminal sets the first pixel section to [0,1664], the second pixel section to [1664,4990], the third pixel section to [4990,10240], and the lower threshold of the fourth pixel section to 10240.
According to the technical scheme, through a creative compression mode, the occupied memory of the picture is reduced to the maximum extent under the condition of ensuring certain picture quality and definition, the storage space is saved, the picture uploading process is accelerated, and the picture quality is ensured.
In one embodiment, the method further comprises: when the uploading of the picture to be uploaded fails, recording the site information of the uploaded data of the picture to be uploaded; and starting breakpoint continuous transmission according to the site information.
Specifically, if the picture uploading fails, the terminal starts breakpoint continuous transmission, and according to the uploaded data, the data is directly transmitted from the last data transmission break when the next transmission task starts, so that the transmission task is smoothly performed, and the time and the flow are saved.
