Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Fig. 1 shows an exemplary system architecture 100 to which embodiments of the method for presenting images or the apparatus for presenting images of the present application may be applied.
As shown in fig. 1, the system architecture 100 may include a camera 101 and a terminal device 102. The camera 101 and the terminal device 102 may be connected by various connection means, such as a data line connection, a network connection, and the like.
The user may take a video or a photograph of an item using the camera 101 and send the taken video or photograph to the terminal device 102. Various communication client applications, such as an image processing application, a video processing application, and the like, may be installed on the terminal device 102.
The terminal device 102 may be hardware or software. When the terminal device 102 is hardware, it may be various electronic devices, including but not limited to a smart phone, a tablet computer, a vehicle-mounted computer, a laptop portable computer, a desktop computer, and the like. When the terminal device 102 is software, it may be installed in the electronic devices listed above. It may be implemented as multiple pieces of software or software modules (e.g., to provide distributed services) or as a single piece of software or software module. And is not particularly limited herein.
It should be noted that the method for presenting an image provided by the embodiment of the present application is generally performed by the terminal device 102. Accordingly, the means for presenting the image is generally provided in the terminal device 102.
It should be understood that the number of cameras and terminal devices in fig. 1 is merely illustrative. There may be any number of cameras and terminal devices, depending on implementation needs.
With continued reference to FIG. 2, a flow 200 of one embodiment of a method for presenting images in accordance with the present application is shown. The method for displaying the image of the embodiment comprises the following steps:
In this embodiment, an execution subject of the method for presenting an image (e.g., the terminal device 102 shown in fig. 1) may acquire a target video in various ways. For example, it is possible to capture a locally stored video or a video photographed in real time by a camera connected to the terminal. A plurality of image frames of the target item may be included in the target video. The target item may be various items to be displayed, such as an on-line merchandise, and the like. The plurality of image frames in the target video may be continuously captured, and different image frames are used for displaying different angles of the target object. It is understood that the first image frame of the target video may be identified as the initial image frame, and the remaining image frames are rotated by different angles with respect to the initial image frame. In some specific applications, the target video includes an image frame of the target object at 360 °.
At step 202, the rotation angle of each image frame relative to the initial image frame is determined.
In this embodiment, the execution subject may determine the rotation angle of each image frame with respect to the initial image frame in various ways. Specifically, the execution subject may determine the rotation angle of each image frame relative to the initial image frame through various parameters of the article and article information present in each image frame. For example, the target object is a hexahedral toy, each face having different patterns and parts. The subject may determine the angle of rotation of each image frame relative to the initial image frame by analyzing features of the pattern of the target item and features of the part in each image frame.
After the rotation angle of each image frame with respect to the initial image frame is determined, the execution subject may select a plurality of image frames from the plurality of image frames as candidate image frames. Specifically, the execution subject may uniformly select a plurality of image frames (one image frame at every 5 ° interval) from the plurality of image frames. Or, several image frames are selected at detailed parts of the target object, and several image frames are selected at parts without details.
And step 204, processing the candidate image frame.
After the candidate image frames are selected, the candidate image frames may be processed. For example, image frames are aligned, background is modified, and so on.
And step 205, displaying the processed candidate image frame.
After processing the candidate image frame, the execution subject may present the processed candidate image frame. Specifically, the execution subject may display the processed candidate image frames in batches. Alternatively, the execution subject may collectively load the image frames after reducing the resolution of each candidate image frame.
The method for displaying the image, provided by the embodiment of the application, solves the problem that the high-definition video or the image is easy to jam when being loaded in the existing article display scheme, improves the loading speed of the high-definition image, and improves the browsing experience of a user.
With continued reference to FIG. 3, a flow 300 of another embodiment of a method for presenting images in accordance with the present application is shown. As shown in fig. 3, the method for presenting an image of the present embodiment may include the steps of:
In this embodiment, each image frame of the target video may include not only the target object but also the logo pattern. Here, the mark pattern may be any irregular pattern. For example, it may be a frame having a complex pattern, or it may be a line segment, etc.
In this embodiment, the execution subject may determine the rotation angle of each image frame with respect to the initial image frame according to the marker pattern in each image frame and the marker pattern in the initial image frame. For example, in the initial image frame, the center line of the marker pattern points to 0 °. In other image frames the centre line of the marker pattern points at 5 °, 10 °, etc., respectively. It may be determined that the other image frames are rotated by 5 °, 10 °, etc. with respect to the initial image frame.
In some optional implementations of this embodiment, the execution body may display the determined rotation angle in real time. And when the rotating angle does not reach 360 degrees, displaying prompt information to remind a user to shoot a 360-degree video of the target object so as to more comprehensively display the target object.
After determining the rotation angle of each image frame, the execution body may determine candidate image frames from the plurality of image frames at intervals of a preset rotation angle. For example, the execution subject may select image frames of 0 °, 5 ° 10 °, 15 ° … … 360 °, respectively, as the candidate image frames. Therefore, the occupied bandwidth when the images are loaded can be reduced, the loading efficiency is improved, and the target objects can be displayed comprehensively.
After determining each candidate image frame, the executive may determine the marker points of the marker pattern in each candidate image frame. Specifically, the marking point may be a specific point in the marking pattern. For example, if the marker pattern is a bird, the marker point may be the eye of the bird. Alternatively, the marker pattern is a line segment, and the marker point may be the midpoint of the line segment.
Then, the execution subject may perform an alignment process on each candidate image frame according to the above-described marker point. Here, the alignment refers to adjusting the coordinates of the marker points in each candidate image frame to a uniform coordinate value.
In this embodiment, each image frame further includes a solid background. The color of the background may be in sharp contrast to the color of the target article. For example, if the target item is dark, the background may be white in color. The target object may be light in color and the background may be black in color. The background is set to be pure color, so that the target object can be conveniently scratched.
After the execution main body aligns each candidate image frame, the mark patterns in each candidate image frame can be removed, and then the pure-color background is adjusted to be transparent, so that the matting of the target object is realized.
After matting the target item, the executive body can also determine a bounding box of the target item. Here, the bounding box may be the smallest circumscribed rectangle of the target item in the image frame. The execution subject may determine the size of the bounding box, and specifically, the size of the bounding box may be determined according to the coordinate parameter of the bounding box. Then, the size of each image frame is adjusted according to the size of the surrounding frame. Specifically, the execution subject may determine a size of a square that can include the bounding box, and then adjust the size of the image frame according to the size of the square.
After the size of the candidate image frame is adjusted, the execution subject may present the adjusted candidate image frame. Specifically, the execution subject may present the adjusted candidate image frame through step 307 or step 308.
In this embodiment, the execution subject may divide the candidate image frames into a plurality of image frame sets according to the rotation angle. Specifically, the executive body may use image frames of 0 °, 25 °, 50 °, 75 ° … … as one image frame set, use image frames of 5 °, 30 °, 55 °, 80 ° … … as another image frame set, and use image frames of 10 °, 35 °, 60 °, 85 ° … … as another image frame set … … until all the image frames of the rotation angles are divided. The execution entity may then batch load the plurality of sets of image frames. Specifically, the execution body may first load an image frame set including image frames of 0 °, 25 °, 50 °, 75 ° … …. After the image frame set is loaded, the image frame set comprising the image frames of 5 degrees, 30 degrees, 55 degrees and 80 degrees … … is loaded until all the image frame sets are loaded.
By this way, the user can first know the general view of the target object and then load more comprehensive details of the target object when the user looks at the target object, thereby reducing the waiting time of the user when browsing the target object,
In this embodiment, when displaying the target object, the resolution of the candidate image frame may also be adjusted first. Specifically, the execution subject may grade the image according to the resolution of the image, for example, divide the image of 8K resolution into 14 levels, which are 4K resolution, 2K resolution, 1K resolution, and so on. The execution subject may load the lower resolution image frame first, e.g., load the 1K resolution candidate image frame first. When the user browses the target object carefully, the candidate image frames with high resolution are loaded in batches.
With continued reference to fig. 4, a schematic illustration of an application scenario of the method for presenting an image according to the present application is shown. In the application scenario of fig. 4, the user places the target item on the background board as shown in fig. 5 and fixes the mobile phone. The background plate is manually rotated, and the camera on the mobile phone is used for photographing the target object. The frame on the background plate shown in fig. 5 is a logo pattern, and the mobile phone can recognize the rotation angle of the target object in real time through the frame. After the video is captured by the camera, one frame image may be selected as a candidate image frame every 5 °. And after the candidate frames are subjected to alignment, background change, screenshot and other processing, the candidate image frames of the target object are displayed on the mobile phone.
The method for displaying the image provided by the above embodiment of the application can provide a reference coordinate system by using the mark pattern, and quickly determine the rotation angle of the article; the pure background is utilized, so that the image matting is easy; part of image frames are extracted from the video, so that the target object is comprehensively displayed, and the image loading speed is increased; by loading the image frames in batches, the waiting time of the user is reduced, and the browsing experience of the user is improved.
