Based on this, in the present application, a picture stitching method is provided, and the present application simultaneously relates to a picture stitching apparatus, a computing device, and a computer readable storage medium, which are described in detail in the following embodiments one by one.
Fig. 1 shows a flowchart of a picture stitching method according to an embodiment of the present application, which specifically includes the following steps:
step 102: and receiving a picture splicing instruction.
The terminal is applied to the terminal, the terminal can be specifically a smart phone, a tablet personal computer, an intelligent wearable device and the like, and the terminal has the capability of processing a picture splicing instruction and completing picture splicing. The picture splicing instruction specifically refers to an instruction sent by a user to splice a plurality of pictures to be spliced into one spliced picture.
In a specific embodiment provided by the application, taking a terminal as an example of a smart phone, a user operates the smart phone to send a picture splicing instruction, and the smart phone receives the picture splicing instruction sent by the user.
Step 104: and responding to the image splicing instruction to acquire the image set to be spliced and target splicing configuration information.
In the process of splicing the pictures, a plurality of pictures for picture splicing need to be determined at first, and the plurality of pictures for picture splicing are called as a picture set to be spliced, that is, the pictures in the picture set to be spliced are used for splicing to generate spliced pictures.
The target splicing configuration information is specifically related configuration information used for determining how to splice the pictures to be spliced, such as splicing direction, splicing angle, splicing proportion and other contents, and according to the target splicing configuration information, how to splice the pictures to be spliced can be determined.
Specifically, the acquiring a to-be-spliced picture set in response to the picture splicing instruction includes:
responding to the picture splicing instruction to obtain an initial picture set to be spliced;
and filtering the pictures in the initial picture set to be spliced according to a preset picture checking rule to obtain the picture set to be spliced.
In general, after sending a picture splicing instruction, a user may access an album of a terminal of the user, and it should be noted that the user authorization is obtained by an operation of accessing the album of the terminal of the user in advance through user permission.
The method includes the steps that through accessing an album of a terminal, pictures which a user wants to splice are selected to form an initial picture set to be spliced, the pictures to be spliced in the initial picture set to be spliced are pictures which are not screened, and it needs to be noted that the pictures selected by the user are not uniform in the initial picture set to be spliced due to different shooting devices, different shooting settings, different shooting angles and the like, for example, a picture 1 is shot transversely, a picture 2 is shot longitudinally, a picture 3 is a terminal screenshot, a picture 4 is a shot panoramic image, a picture 5 is a picture with an abnormal aspect ratio obtained after the user cuts out, a picture 6 is a moving picture and the like, and the pictures which are different in types cannot be spliced together effectively, so that the pictures which do not meet the splicing requirements in the initial picture set to be spliced are required to be deleted, filtered and filtered.
Specifically, data type verification needs to be sequentially performed on the pictures to be spliced in the initial picture set to be spliced, and whether the pictures are of a type that can be subjected to picture splicing is determined, for example, when the GIF moving pictures cannot be spliced, the GIF moving pictures in the initial picture set to be spliced need to be deleted. And checking the picture information of the picture to be spliced, and judging whether the picture direction, the filling mode, the aspect ratio and the like of the picture to be spliced are consistent. In addition, the picture resources are required to be processed, and the pictures with the size larger than the preset threshold value are compressed according to the proportion, so that the situation that the picture resources occupy too much memory and influence the subsequent display performance is avoided.
After filtering according to the rules, filtering and deleting the pictures to be spliced which do not meet the requirements in the initial picture set to be spliced, reserving the pictures to be spliced which meet the rules, and obtaining the picture set to be spliced.
The method comprises the steps that a user selects a picture set to be spliced, and also needs to select corresponding splicing configuration information according to actual requirements of the user, and the user determines a final splicing row form, wherein specifically, a picture splicing instruction comprises a splicing configuration identifier;
responding to the image splicing instruction to acquire target splicing configuration information, wherein the target splicing configuration information comprises:
and acquiring target splicing configuration information in a preset configuration information base according to the splicing configuration identifier.
The splicing configuration identifier specifically refers to an identifier for uniquely determining splicing configuration information, and one splicing configuration identifier corresponds to unique splicing configuration information. In practical application, the splicing configuration information can be displayed in the terminal in a visual form, and a user can select splicing configuration information which the user wants from a plurality of splicing configuration information displayed in the terminal in a preview form and can also customize the splicing configuration information in a customized form. And acquiring a corresponding splicing configuration identifier for the selected splicing configuration information, sending the splicing configuration identifier to the terminal, and acquiring corresponding target splicing configuration information in a preset configuration information base by the terminal according to the splicing configuration identifier. For the user-defined splicing configuration information, a new splicing configuration identifier can be created for the user-defined splicing configuration information and stored in a preset configuration information base, so that the user-defined splicing configuration information can be modified or deleted conveniently in the follow-up process.
In a specific embodiment provided by the present application, the above example is continued, 3 to-be-spliced pictures are obtained according to the picture splicing instruction to form a to-be-spliced picture set, and meanwhile, the target splicing configuration information C is obtained in the preset configuration information base according to the splicing configuration identifier in the picture splicing instruction.
Step 106: and splicing the pictures to be spliced in the picture set to be spliced based on the target splicing configuration information to generate a spliced picture preview frame.
The spliced picture preview frame is generated after the pictures to be spliced in the picture set to be spliced are spliced and is convenient for a user to browse.
Specifically, splicing the to-be-spliced pictures in the to-be-spliced picture set based on the target splicing configuration information, and splicing a picture preview frame, includes:

The number of the subframes in the preview layout frame is the same as the number of the pictures to be spliced in the picture set to be spliced, for example, if 5 pictures exist in the picture set to be spliced, 5 subframes exist in the preview layout frame; if there are 10 pictures in the picture set to be spliced, there are 10 subframes in the preview layout frame, each subframe corresponds to one picture to be spliced, after the preview layout frame is generated, each picture to be spliced in the picture set to be spliced is input into the subframe of the corresponding preview layout frame, and the corresponding spliced picture preview frame is generated, for example, the preview layout frame is longitudinally arranged, and there are 5 pictures to be spliced in the picture set to be spliced, 5 subframes are longitudinally arranged, and the 5 pictures to be spliced are input into the subframes corresponding to one another, so that the spliced picture preview frame composed of the 5 pictures to be spliced is generated.
In a specific embodiment provided by the present application, a preview layout frame is generated according to the target splicing configuration information C along the above example, where the preview layout frame includes 3 subframes, namely subframe 1, subframe 2, and subframe 3, and the 3 subframes are longitudinally arranged to form the preview layout frame, and 3 to-be-spliced pictures are respectively input into the 3 subframes, that is, picture 1 to be spliced is input into subframe 1, picture 2 to be spliced is input into subframe 2, and picture 3 to be spliced is input into subframe 3, so as to generate a spliced picture preview frame composed of the 3 to-be-spliced pictures.
Step 108: and receiving a frame processing instruction aiming at the spliced picture preview frame, wherein the frame processing instruction is determined according to the operation information collected by the sensor.
After the spliced picture preview frame is generated, a user can preview the generated initial spliced picture through the spliced picture preview frame, the generated initial spliced picture is not adjusted at the moment, and the user needs to adjust the initial spliced picture. Namely, sending a frame processing instruction to the spliced picture preview frame.
It should be noted that in the present application, the user directly issues a frame processing instruction for the stitched picture preview frame, instead of processing the initial stitched picture itself. The method includes the steps that adjustment processing is conducted on a spliced picture preview frame, a user conducts Pinch gesture and Pan gesture processing on a terminal, and sends a corresponding frame processing instruction to the terminal, for example, the spliced picture preview frame is enlarged or reduced through the Pinch gesture, the spliced picture preview frame is dragged through the Pan gesture, and the like. And sending a frame processing instruction to the spliced picture preview frame, determining the matching degree of processing only by considering the deviation value of the sub-frame without considering information such as the number, the position size and the like of the pictures to be spliced, loading the pictures to be processed in the sub-frame, adjusting the pictures to be processed along with the sub-frame without repeatedly loading the pictures to be processed, reducing the processing pressure of a terminal processor and improving the processing efficiency.
Specifically, receiving a frame processing instruction for the stitched picture preview frame includes:
and receiving frame adding and deleting instructions and/or frame adjusting instructions aiming at the spliced picture preview frame.
The frame processing instruction specifically comprises a frame adding and deleting instruction and a frame adjusting instruction, and when the user processes the spliced picture browsing frame, the user can add or delete a subframe, namely, add or delete a picture to be spliced, and can also adjust the size and the position of the subframe, namely, adjust the size and the position of the picture to be spliced.
In a specific embodiment provided by the application, when a user finds that less than one picture is spliced when browsing a spliced picture preview frame, a frame adding and deleting instruction is sent, a subframe is added, and a new picture to be spliced is added; when a user browses the spliced picture preview frame, the user finds that more than one picture is selected, selects the picture to be spliced to be deleted and sends a frame adding and deleting instruction, and deletes the sub-frame corresponding to the picture to be spliced; when browsing the spliced picture preview frame, a user finds that the position of the picture to be spliced needs to be adjusted, and the positions of the 2 nd picture and the 3 rd picture need to be exchanged, then a frame adjusting instruction is sent out, and the positions of the subframe of the 2 nd picture and the subframe of the 3 rd picture are adjusted to be exchanged; when a user finds that the 2 nd picture needs to be reduced when browsing the spliced picture preview frame, a frame adjusting instruction is sent out, and the subframe of the 2 nd picture is reduced.
Step 110: and processing the spliced picture preview frame based on the frame processing instruction to generate a target spliced picture.
After a frame processing instruction for the spliced picture preview frame is received, corresponding processing is performed on the spliced picture preview frame according to the frame processing instruction, and a new target spliced picture is generated.
Specifically, processing the stitched picture preview frame based on the frame processing instruction includes:
under the condition that the frame adding and deleting instruction is received, adding a new subframe according to the frame adding and deleting instruction, and adding a new picture to be spliced or deleting a subframe in the spliced picture preview frame;
and under the condition that the frame adjusting instruction is received, exchanging the sequence of the sub-frames in the spliced picture preview frame or adjusting the size of the sub-frames in the spliced picture preview frame according to the frame adjusting instruction.
Under the condition that a frame adding and deleting instruction is received, an operation of adding a new subframe and adding a new picture to be spliced is required to be executed according to the specific content of the frame adding and deleting instruction, or an operation of deleting a subframe in a spliced picture preview frame according to the frame adding and deleting instruction is required to be executed.
In a specific embodiment provided by the application, taking the add subframe as an example, when a frame add/delete instruction for the preview frame of the spliced picture is received, the instruction is analyzed to obtain the specific content of the instruction as the add subframe, at least one newly added picture to be spliced is obtained at the same time, a corresponding number of the newly added subframes are added according to the number of the newly added pictures to be spliced, and each newly added picture to be spliced is filled into each newly added subframe.
In a specific embodiment provided by the application, taking a subframe deletion as an example, when a frame add-delete instruction for a stitched picture preview frame is received, the instruction is analyzed, a delete instruction for a target subframe in the instruction is obtained, the target subframe is determined and deleted, parameters of each subframe in the stitched picture preview frame after the target subframe is deleted are updated and calculated in real time, and a new stitched picture preview frame is displayed.
In practical application, in addition to performing an operation of adding or deleting a subframe in the spliced picture preview frame, the position and size of the subframe in the spliced picture preview frame can be adjusted. For example, when two adjacent subframes are spliced, the subframes may be adjusted to overlap repeated portions of the pictures to be spliced in the subframes, so that two consecutive pictures to be spliced are spliced into a complete picture, and when a plurality of subframes are overlapped, the stacking order of each frame may be determined.
In a specific embodiment provided by the present application, the size of the subframe in the stitched image preview frame may also be adjusted, for example, a user may implement an operation of adjusting the size of the subframe by pinching or separating two fingers on a terminal screen, when the user performs the pinching operation, the size of the subframe may be reduced, and when the user performs the separating operation, the size of the subframe may be enlarged, so that the stitched image may be changed accordingly according to the requirement of the user.

determining a target subframe in the spliced picture preview frame according to the frame adjusting instruction, and determining a scaling coefficient of the target subframe;
adjusting a size of the target subframe based on the scaling factor.
When the size of the subframe in the spliced picture preview frame is adjusted, a target subframe, namely the subframe needing to be adjusted, is determined according to a frame adjusting instruction, the zoom coefficient of the target subframe is determined through gesture operation, and then the final size of the target subframe after the adjusting instruction can be calculated according to the initial coefficient of the target subframe in the spliced picture preview frame.
The picture splicing method provided by the application receives the frame processing instruction for the spliced picture preview frame, processes the spliced picture preview frame according to the frame processing instruction, does not need to process an initial spliced picture generated by the pictures to be spliced, avoids traversing each picture to be spliced when the initial spliced picture is adjusted and modified, does not need to recalculate the layout of the pictures to be spliced when being inserted, deleted, adjusted in sequence and adjusted in size, directly processes the spliced picture preview frame, converts the splicing operation of the pictures into the layout operation of the sub-frame, saves computing resources, and improves the interactive experience and visual experience of a user in the process of splicing the pictures.
In another specific embodiment provided herein, the method further comprises:
and loading the spliced picture preview frame in a lazy loading mode, and storing the loaded part in the spliced picture preview frame into a cache.
Lazy loading is a loading mode for improving terminal performance, when a user scrolls a page, the content in a starting area is preferentially loaded, and the content in other parts is loaded after entering a visual area, so that the service performance is improved. When carrying out the picture concatenation, the size of picture all can exceed the scope of terminal screen usually, if the picture after will splicing is whole to be loaded and the user does not look over, will waste the loading resource, consequently adopt lazy loading's form, will enter into the partial loading in the visual region at terminal to add the part that the loading was accomplished in previewing the frame to the buffer memory in with the concatenation picture, be convenient for multiplex in subsequent handling, promote resource utilization.
Correspondingly, after the target stitched picture is generated, the method further comprises:
and releasing the spliced picture preview frame loaded in the cache.
After the target spliced picture is generated, it is shown that the processing of the spliced picture preview frame is completed, and at this time, the spliced picture preview frame which is stored in the cache and loaded well can be deleted without storing the spliced picture preview frame again, so that the corresponding cache control is released, and the resource utilization rate of the terminal is improved.
In practical application, after a plurality of pictures to be spliced are spliced, the size of the obtained target spliced picture is the sum of the sizes of all the pictures to be spliced, for example, the size of one picture to be spliced is 3M, if there are 10 pictures to be spliced, the size of the target spliced picture may reach 30M or even higher, and based on this, after the target spliced picture is generated, the method further includes:
and processing the target spliced picture based on a preset picture compression rule to obtain a compressed target spliced picture.
In order to reduce the consumption of a memory of the terminal and improve the usability of a target spliced picture, the target spliced picture can be compressed after the target spliced picture is obtained, and specific picture compression rules are subject to practical application, such as compression based on a preset length-width ratio, compression based on preset pixels, compression based on a preset picture size, and the like.
