Referring to fig. 1, a first embodiment of the present invention provides a three-dimensional panorama picture displaying method, which may be executed by a mobile terminal having a touch-sensitive display surface, and in particular, executed by one or more processors within the mobile terminal, to implement the following steps:
and S101, requesting a server to acquire the needed resources of the three-dimensional panoramic picture.
In this embodiment, the mobile terminal may be a smart phone, which is installed with an operating system. The operating system may be an IOS system, an android system, or another operating system suitable for the mobile terminal, which is not limited in this invention.
In this embodiment, the mobile terminal is further installed with an APP to implement the three-dimensional panoramic picture display method of this embodiment, where the APP may be a specific APP or a browser, and the present invention is not limited specifically.
In this embodiment, resources of a plurality of three-dimensional panoramic pictures are stored in the server, and through the APP, the mobile terminal can initiate access to the server, so that a user can browse the three-dimensional panoramic pictures in the server, which are interesting to the user.
S102, displaying a part of the three-dimensional panoramic picture on a touch-sensitive display surface according to the resource of the three-dimensional panoramic picture.
S103, detecting the moving operation of the user on the touch-sensitive display surface to the three-dimensional panoramic picture, and moving the three-dimensional panoramic picture at a corresponding moving speed according to the moving operation to dynamically update the display part of the three-dimensional panoramic picture displayed on the touch-sensitive display surface.
In this embodiment, if a user is interested in a three-dimensional panoramic picture, the user can click on the thumbnail of the three-dimensional panoramic picture to view the panoramic picture. Since the three-dimensional panoramic picture is usually relatively large, and the touch-sensitive display surface of the mobile terminal is relatively small, the apparent touch-sensitive display surface can only display a part of the three-dimensional panoramic picture. The user can update the display part of the three-dimensional panoramic picture displayed on the touch-sensitive display surface by dragging or moving the three-dimensional panoramic picture, so that dynamic picture browsing is realized. Wherein the moving speed of the three-dimensional panoramic picture is adjusted according to the intensity of the user's dragging or moving. For example, if the user performs a sliding operation on the touch-sensitive display surface, the three-dimensional panoramic picture will move correspondingly, and particularly, the moving speed is related to the speed or amplitude of the sliding operation, so that the user can adjust the speed of browsing the three-dimensional panoramic picture according to the needs of the user.
In addition, the embodiment also provides a way for the three-dimensional panoramic picture to automatically move, and the user can input the desired moving speed, so that the three-dimensional panoramic picture automatically moves or rotates according to the moving speed to update the display area.
As shown in fig. 2 and 3, fig. 2 is a schematic diagram showing a part of a three-dimensional panoramic picture displayed on a touch-sensitive display surface (it should be understood that fig. 2 is only an example for easy understanding, and in fact no real picture exists outside the touch-sensitive display surface), and fig. 3 is a schematic diagram showing the three-dimensional panoramic picture of fig. 2 on a mobile terminal after moving the three-dimensional panoramic picture from right to left by a certain distance.
And S104, when the updated display part contains the marked interesting region, reducing the moving speed of the three-dimensional panoramic picture so that the user has more time to observe the current display part.
In this embodiment, for each three-dimensional panoramic picture, one or more regions of interest may be marked, and these regions of interest are generally important regions, detail regions or regions that are easily noticed by people of the three-dimensional panoramic picture. For example, for a three-dimensional panoramic picture inside a house, the region of interest may be an indoor ceiling lamp region, and for a three-dimensional panoramic picture in a scenic spot or an outdoor environment, the region of interest may be some scenic spots, leisure spots, etc. in the whole environment. And the region of interest can be initially marked by a drafter when uploading the three-dimensional panoramic picture and stored in the server together with the three-dimensional panoramic picture.
In this embodiment, some regions of interest are sometimes not so apparent in the entire three-dimensional panoramic picture, i.e., not very visually observable and need to be magnified or scrutinized to be found. Therefore, if the user moves the picture with a relatively fast moving speed, the user may miss the regions of interest, such as the region of interest a in fig. 2 or fig. 3, because the user does not have enough time to observe the picture.
Therefore, in this embodiment, when the user moves the three-dimensional panoramic picture, if the current display portion on the touch-sensitive display surface includes the marked region of interest, the mobile terminal will reduce the moving speed of the three-dimensional panoramic picture, so that the user has more time to observe the current display portion. If the user finds that the current region of interest is the region that the user wants to search for, the user can click the region of interest, at this time, the three-dimensional panoramic picture stops moving, and the user can zoom in on the region of interest or perform other operations and the like.
In summary, in the three-dimensional panoramic picture displaying method provided by this embodiment, in the process of moving the three-dimensional panoramic picture by the user, if it is determined that the current display portion includes the region of interest with the label, the moving speed of the three-dimensional panoramic picture is reduced, so that the user has more time to view the current display portion, and further, whether the region of interest is a target region that the user wants to find is determined, thereby avoiding a situation that the user misses some regions of interest due to fast movement, and improving the efficiency of browsing the whole three-dimensional panoramic picture by the user.
In order to facilitate an understanding of the invention, some preferred embodiments of the invention are described further below.
In one embodiment, step S104 specifically includes:
acquiring a first coordinate of a first central point of an interest area on a touch-sensitive display surface and a second coordinate of a second central point of the touch-sensitive display surface;
obtaining the distance between a first central point and the second central point along the moving direction according to the first coordinate and the second coordinate;
generating a hysteresis coefficient according to the distance, and correcting the moving speed of the three-dimensional global picture according to the hysteresis coefficient so as to reduce the moving speed; the hysteresis coefficient is proportional to the distance, and is less than or equal to 1.
In this embodiment, since the user may put more attention on the display center position of the touch-sensitive display area, in order to improve the browsing efficiency of the three-dimensional panoramic display picture, the moving speed may be set to be smaller closer to the second center point and larger relatively far from the second center point.
Specifically, the method comprises the following steps:
first, a first coordinate of a first center point of a region of interest on a touch-sensitive display surface and a second coordinate of a second center point of the touch-sensitive display surface are obtained.
And then, acquiring the distance between the first central point and the second central point along the moving direction according to the first coordinate and the second coordinate.
For example, as shown in fig. 3, assuming that the first coordinates of the first center point of the region of interest a are (X1, Y1), the second coordinates of the second center point B are (X2, Y2), the distance is an absolute value of (X1-X2) if the moving direction is left-right movement, and the distance is an absolute value of (Y1-Y2) if the moving direction is up-down movement.
Finally, generating a hysteresis coefficient according to the distance, and correcting the moving speed of the three-dimensional global picture according to the hysteresis coefficient so as to reduce the moving speed
Specifically, in one implementation, the corrected moving speed is set to V 1 Initial moving speed is V 0 The distance between the first center point and the second center point along the moving direction is d, the distance between the touch-sensitive display surface and the second center point along the moving direction is L, and the hysteresis coefficient is t; then:
t＝d/L (2)
wherein N is a positive integer greater than or equal to 2.
In this embodiment, although it is defined that the closer the first central point and the second central point is, the smaller the delay coefficient is, that is, the smaller the moving speed thereof is, if the process is a linear change process, when the two central points are close to each other (as shown in fig. 4), the moving speed is very slow, which may result in that the moving speed of the three-dimensional panoramic picture is very slow, and a user may mistakenly think that the mobile terminal has a jam or a fault, which brings a bad user experience.
Therefore, in this embodiment, a piecewise function is used to control the moving speed, when the distance is greater than a certain value, the hysteresis coefficient or the moving speed is gradually reduced along with the decrease of the distance, and when the distance is less than the certain value, the moving speed is kept unchanged, so as to ensure that the moving speed of the three-dimensional panoramic picture is not too slow when the first central point and the second central point are close to each other.
In this embodiment, N may be a value according to actual needs, for example, N may be a value of 2, 3, or the like. Taking N =2 as an example, when the distance d between the first central point and the second central point is greater than or equal to L/2, the moving speed decreases with the decrease of the distance, and when the distance d between the first central point and the second central point is less than L/2, the moving speed is kept at V 0 /2, i.e. the speed of movement is at least equal to or greater than V 0 And/2, therefore, the efficiency of browsing pictures and searching the interested region can be considered.
In this embodiment, N may be a fixed value or a variable value, and particularly, in this embodiment, V is within a predetermined range 0 The larger N.
Wherein V is taken into account 0 The larger the moving speed of the picture is, the larger the initial moving speed of the picture is, so that the value of N can be properly increased to reduce the moving speed of the picture to a greater extent, and the picture is prevented from being too fast moved to be seen clearly. But the value of N cannot be too large, which would result in a stuck-like phenomenon due to too slow movement.
In this embodiment, the corresponding relationship between the speed range and N may be predefined, so that N may be adjusted according to the actual moving speed.
On the basis of the above embodiment, in a preferred embodiment of the present invention, the method further includes:
and when the distance between the first central point and the second central point along the moving direction is smaller than a preset threshold value, displaying a visual identifier at the first central point.
In this embodiment, when the region of interest is close to the second center point, a visual identifier, such as a luminous icon or a circle, a cross, or the like, may be set at the first center point of the region of interest to remind the user that the currently displayed portion has the region of interest, where the identifier automatically disappears after the region of interest is far from the second center point.
Preferably, the region of interest has a predetermined label, which is previously provided on the three-dimensional panoramic image and is not visible when displayed; then the method further comprises the following steps:
and counting the attention degree of each area of the three-dimensional panoramic picture of the user, and sending the attention degree of each area of the three-dimensional panoramic picture to the server so that the server adds the label in the corresponding area of the three-dimensional panoramic picture according to the attention degree.
In this embodiment, in addition to the initially set region of interest, the mobile terminal may also count the attention degree of each region when each user browses the three-dimensional panoramic picture, where the attention degree may be obtained by, for example, determining the frequency or the number of times that the user zooms in and clicks on the viewed region. If a certain area is zoomed in or clicked to view by more users, it is indicated that the area gets attention of more people, and therefore, it can also be set as an area of interest.
In the embodiment, the region of interest is generated according to the common behaviors of most users, so that the richness and the reasonableness of the region of interest can be ensured.
Referring to fig. 5, a second embodiment of the present invention further provides a three-dimensional panorama picture displaying apparatus, including:
a resource requesting unit 210, configured to request a server to obtain a resource of a required three-dimensional panoramic picture.
In this embodiment, resources of a plurality of three-dimensional panoramic pictures are stored in the server, and a user can view the three-dimensional panoramic picture interested in the user by accessing the server.
A display unit 220, configured to display a portion of the three-dimensional panoramic picture on a touch-sensitive display surface according to the resource of the three-dimensional panoramic picture.
And the moving unit 230 is configured to detect a moving operation of the user on the touch-sensitive display surface on the three-dimensional panoramic picture, and move or rotate the three-dimensional panoramic picture at a corresponding moving speed according to the moving operation, so as to dynamically update a display portion of the three-dimensional panoramic picture displayed on the touch-sensitive display surface.
In this embodiment, if a user is interested in a three-dimensional panoramic picture, the user can click on the thumbnail of the three-dimensional panoramic picture to view the panoramic picture. Since the three-dimensional panoramic picture is usually relatively large, and the touch-sensitive display surface of the mobile terminal is relatively small, the apparent touch-sensitive display surface can only display a part of the three-dimensional panoramic picture. The user can update the display part of the three-dimensional panoramic picture displayed on the touch-sensitive display surface by dragging or moving the three-dimensional panoramic picture, so that dynamic picture browsing is realized. Wherein the moving speed of the three-dimensional panoramic picture is adjusted according to the intensity of the dragging or moving of the user. For example, if the user performs a sliding operation on the touch-sensitive display surface, the three-dimensional panoramic image will correspondingly move, and particularly, the moving speed of the three-dimensional panoramic image is related to the speed or amplitude of the sliding operation, so that the user can adjust the speed of browsing the three-dimensional panoramic image according to the user's own needs.
In addition, the embodiment also provides a way for the three-dimensional panoramic picture to automatically move, and the user can input the desired moving speed, so that the three-dimensional panoramic picture automatically moves or rotates according to the moving speed to update the display area.
A moving speed adjusting unit 240, configured to reduce the moving speed of the three-dimensional panoramic picture when it is determined that the updated display portion includes the marked region of interest, so that the user has more time to observe the current display portion.
In the present embodiment, for each three-dimensional panoramic picture, one or more regions of interest may be labeled, and these regions of interest are typically important regions, detail regions or regions that are easily noticeable to people. For example, for a three-dimensional panoramic picture inside a house, the interested region may be an indoor ceiling lamp region, and for a three-dimensional panoramic picture in a scenic spot or outdoor environment, the interested region may be some scenic spots, leisure points, etc. in the whole environment. The region of interest can be initially marked by a drafter when uploading the three-dimensional panoramic picture and stored in the server together with the three-dimensional panoramic picture.
In this embodiment, some regions of interest are sometimes not so apparent in the entire three-dimensional panoramic picture, i.e., not very visually observable and need to be magnified or scrutinized to be found. Therefore, if the user moves the picture at a relatively fast moving speed, the user may miss the regions of interest because the user does not have enough time to observe the picture.
Therefore, in this embodiment, when the user moves the three-dimensional panoramic picture, if the current display portion of the touch-sensitive display surface includes the marked region of interest, the mobile terminal will reduce the moving speed of the three-dimensional panoramic picture, so that the user has more time to observe the current display portion. If the user finds that the current region of interest is the region that the user wants to search for, the user can click the region of interest, at this time, the three-dimensional panoramic picture stops moving, and the user can zoom in on the region of interest or perform other operations and the like.
In summary, in the process of moving the three-dimensional panoramic picture by the user, if it is determined that the current display portion includes the region of interest with the label, the three-dimensional panoramic picture display device provided in this embodiment reduces the moving speed of the three-dimensional panoramic picture, so that the user has more time to view the current display portion, and further determines whether the region of interest is the target region that the user wants to find, thereby avoiding the occurrence of a situation that the user misses some regions of interest due to fast movement, and improving the efficiency of browsing the whole three-dimensional panoramic picture by the user.
Preferably, the moving speed is generated according to the operation intensity of the moving operation; the operation strength is operation strength or operation speed.
As shown in fig. 6, preferably, the moving speed adjusting unit 240 specifically includes:

Preferably, the corrected moving speed is set to V 1 Initial moving speed is V 0 The distance between the first center point and the second center point along the moving direction is d, the distance between the touch-sensitive display surface and the second center point along the moving direction is L, and the hysteresis coefficient is t; then:

wherein N is a positive integer greater than or equal to 2.
Preferably, within a predetermined range, V 0 The larger N.
