Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
In the embodiment of the invention, a shake-free and more natural panoramic page switching effect can be formed, on the premise of ensuring interestingness, user experience is greatly improved, a user is attracted to browse more panoramic contents, and the vertical range of the panoramic contents is expanded.
The following describes a method and an apparatus for controlling movement of a shooting point when a panoramic page is switched according to an embodiment of the present invention with reference to the accompanying drawings.
Fig. 1 is a flowchart of a method for controlling movement of a shot point when a panorama page is switched, as shown in fig. 1, the method including the steps of:
Specifically, a panoramic page refers to rendering 3D (3 Dimensions) scene content on a webpage through webgl (Web Graphics Library) technology, providing a more stereoscopic and spatial visualized content form, and virtualizing a 3D box space, generally using the principle of light reflection, and virtualizing a 3D box space, where panoramic content displayed on the surface of a 3D sphere or cube, that is, a pixel combination of a reflection point of a current viewpoint in the virtual 3D box space.
It can be understood that the panoramic page may be composed of 6 frames, i.e., front, back, left, right, up, and down, and in the initial state, the front frame is displayed, and the user may drag the page or may browse other frames by means of a gyroscope or the like.
In the webgl technology, the shooting direction of the shooting equipment is a 3-dimensional space coordinate, and the shooting equipment shoots the content in the space towards the corresponding space point and then renders the content on a webpage.
It should be noted that the picture direction in front of the panorama page means that the coordinates of the current viewpoint are set as the coordinates of the center shooting point, then the z-axis coordinate z of the current viewpoint is z +1, and the shooting device shoots the picture direction in front of the panorama toward the current viewpoint.
Therefore, after the switching of the panoramic page is triggered by clicking, pressing and the like, the current viewpoint moves to the central shooting point of the panoramic icon (wherein, when z is greater than 0, z is equal to z +1, and when z is less than 0, z is equal to z-1), the experience given to the user is that the panoramic icon moves to the central position of the screen, then the shooting device moves linearly towards the central shooting point of the panoramic icon in the 3D space, and the experience given to the user is that the panoramic icon passes through to a new panoramic space.
As shown in fig. 2a, the photographing apparatus moves from the page shot point O to the center shot point Q of the panoramic icon and always photographs toward the current viewpoint Q', and as the photographing apparatus approaches the center shot point Q of the panoramic icon, the variation of the photographing contents during the movement becomes larger and larger, for example, the BA amplitude is larger than CB, thereby causing the page shake.
Therefore, in the embodiment of the present invention, by changing the moving manner from the shooting point to the center shooting point of the panoramic icon and generating a moving path of a curved track, the change of the shooting content of the shooting device in the moving process is within a small fluctuation range, so that the jitter interference can be eliminated, and the specific moving path is the OPQ curved track shown in fig. 2 b.
As can be seen from fig. 2B, when the imaging device (i.e., the shooting point) shoots the point B of the panoramic icon at the point P, the range of the change of the shot content during the moving process is smaller than that of the original mode, i.e., the point B of the panoramic icon is shot at the point P in fig. 2a, so that the page can smoothly enter a new panorama without shaking.
In one embodiment of the invention, the panoramic icon is a 3D hover ball.
And 102, acquiring a current viewpoint, and determining a first mobile relay point according to the current viewpoint.
And 103, determining a curve track according to the first moving relay point.
It can be understood that there are many ways to obtain the current viewpoint and determine the first mobile relay point according to the current viewpoint, for example, as follows:
in a first example, a first reference point of the panoramic icon is determined according to the page shot point and the current viewpoint, a second reference point of the panoramic icon is determined according to the center shot point and the current viewpoint, a third reference point of the panoramic icon is determined according to the first reference point and the second reference point of the panoramic icon, and a first mobile relay point is determined according to the third reference point and the current viewpoint.
Taking fig. 2b as an example, determining a first reference point of the panorama icon as C according to the page shot point O and the current viewpoint Q'; and determining a second reference point of the panoramic icon as A according to the central shooting point Q and the current viewpoint Q ', determining a third reference point of the panoramic icon as B according to the first reference point C and the second reference point A of the panoramic icon, and determining a first mobile relay point P according to the third reference point B and the current viewpoint Q'.
In a second example, a function is simulated by acquiring a plurality of moving relay points corresponding to a plurality of current viewpoints in different scenes, and when the input of the function is the current viewpoint, the output is the corresponding first moving relay point.
Thus, a curved trajectory, such as the curved trajectory OPQ shown in fig. 2b, is determined from the first moving relay point. Therefore, by generating a curve moving path, the variation of the shooting content of the shooting device in the moving process is within a small variation range, and the jitter interference can be eliminated.
And 104, when a panoramic page switching instruction is received, controlling the shooting point to move from the page shooting point to the center shooting point of the panoramic icon along the curve track.
Therefore, when a panoramic page switching instruction (a mode of dragging a page or a gyroscope or the like) is received, the shooting point can be controlled to move from the page shooting point to the center shooting point of the panoramic icon along a curve track. For example, in fig. 2b, the control point moves along a curved path OPQ.
As a scene implementation, as shown in fig. 3a to 3D, the panoramic icon is a 3D floating ball, and by generating a curved track, the shooting point is switched from the sulwood lake to the summer tower within a small variation range during the moving process, so that a jitter-free and more natural panoramic page switching effect can be formed.
To sum up, the method for controlling movement of a shot point during switching of a panoramic page according to the embodiments of the present invention obtains a page shot point of a page, obtains a center shot point of a panoramic icon, obtains a current viewpoint, and determines a first moving relay point according to the current viewpoint, thereby determining a curved track according to the first moving relay point, and when a panoramic page switching instruction is received, controls the shot point to move from the page shot point to the center shot point of the panoramic icon along the curved track. Therefore, by generating the curve track, the change of the shooting content of the shooting point in the moving process is within a small variation range, the shaking problem during the switching of the panoramic page is solved, the shaking-free and more natural panoramic page switching effect can be formed, on the premise of ensuring interestingness, the user experience is greatly improved, the user is attracted to browse more panoramic contents, and the vertical range of the panoramic contents is expanded.
Fig. 4 is a flowchart of a moving control method of a shot point at the time of panorama page switching according to another embodiment of the present invention, as shown in fig. 4, the method including the steps of:
It should be noted that step 201 can refer to the description of step 101, and is not described in detail here.
And 203, determining a fourth reference point of the random panorama icon according to the second reference point, the current viewpoint and the central shooting point, and taking the fourth reference point as a second mobile relay point, wherein a curve track is determined according to the first mobile relay point, the second mobile relay point and the page shooting point.
And step 204, controlling the shooting point to move to the second moving relay point from the page shooting point along the curve track, and controlling the shooting point to move linearly to the center shooting point of the panoramic icon from the second moving relay point.
Specifically, continuing with fig. 2B for explanation, a first reference point of the panoramic icon is determined to be C according to the page shot point O and the current viewpoint Q ', a second reference point of the panoramic icon is determined to be a according to the center shot point Q and the current viewpoint Q ', a third reference point of the panoramic icon is determined to be B according to the first reference point C and the second reference point a of the panoramic icon, and a first mobile relay point P is determined according to the third reference point B and the current viewpoint Q '.
Therefore, as shown in fig. 2c, a fourth reference point D of the panoramic icon at any time is determined according to the second reference point a, the current viewpoint Q' and the central shooting point Q, and the fourth reference point D is used as a second moving relay point, so that the shooting point is controlled to move from the page shooting point O to the second moving relay point along the curved track OPQ, and the shooting point is controlled to move linearly from the second moving relay point to the central shooting point of the panoramic icon, thereby generating a curved moving path, so that the change of the shooting content of the shooting device in the moving process is within a small variation range, and the jitter interference can be eliminated. And the method can help the user browse the panoramic content well, expand the vertical range of the panoramic content, deepen the user viscosity in the fields of real estate, tourism, education and the like, and trigger the deep-level service fusion.
Based on the above description of the embodiments, it can be understood that, for a panoramic icon with z <0, if the current viewpoint is set to z ═ z-1 (z represents the z coordinate of the central shot point of the panoramic icon), the same dithering noise is generated as described above, and at the same time, the moving range of the shot content during the moving process is larger, and the dithering noise is larger, because the moving range does not go to the front picture but to the back picture of the new panorama. How to process the following pictures into the new panorama is described below in connection with fig. 5.
Fig. 5 is a flowchart of a moving control method of a shot point at the time of panorama page switching according to still another embodiment of the present invention, as shown in fig. 5, the method including the steps of:
And step 302, judging whether a preset condition is met according to the position information of the panoramic icon.
And 303, if the preset condition is met, reversely mapping the panoramic icon.
It will be appreciated that the jitter disturbance occurs before the new panorama page is displayed, the current viewpoint z-bin is set to z-1 (z initially represents the center shot of the panorama icon), the latter pictures of the new panorama are entered, and the former pictures are not.
Specifically, the position information z of the panoramic icon is acquired, and the preset condition that z is less than 0 is satisfied, and in addition to the curved moving path in the above manner, the panoramic icon needs to be reverse-mapped, that is, the front picture and the rear picture of the original panoramic icon are interchanged, the left picture and the right picture are interchanged, the upper picture and the lower picture are turned upside down and turned upside down, the current viewpoint is set to be z-1 (z initially represents the central shooting point of the panoramic icon), and the moving path is as shown in fig. 2 d.
The preset conditions can be set according to actual use requirements, and only the panoramic icon needs to be subjected to reverse mapping, that is, the rear picture entering a new panorama can be determined, and the front picture is not entered.
In fig. 2d, the shooting point moves from point O to point Q along the OPQ curve, and the direction of point Q' is always shot (the current viewpoint is the direction of the screen on the back of the panorama).
The traversal effect of the panoramic icon on the back of the panorama can be known, for example, by observing a gyro sector on the page, which represents the position of front z >0 facing upwards and the position of back z <0 facing downwards, whether the panoramic icon is on the screen on the back of the panorama.
It should be noted that, if the reverse mapping is not performed, a large rotation angle of the picture occurs during the traversing process, which affects the user experience. Therefore, the jitter interference can be eliminated by enabling the shooting content of the shooting device to change within a small fluctuation range in the moving process through the reverse mapping.
As a scene implementation, as shown in fig. 6a to 6D, the panoramic icon is a 3D floating ball, and by performing reverse mapping on the 3D floating ball, a picture on the back side of the panoramic icon is actually a front picture of the panoramic icon, and smooth switching effect can be generated by a shooting device with a small rotation.
