It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
Example 1
Fig. 1 is a flowchart of a scene switching method according to an embodiment of the present invention. The embodiment is applicable to scene picture switching, and typically, can be applied to scene switching in a virtual reality environment. The method may be performed by a scene cut device, which may be implemented in software and/or hardware, typically the decoration may be a virtual reality device, such as virtual reality glasses. Referring to fig. 1, the scene switching method provided in this embodiment includes:
s110, responding to a scene switching event, and performing fuzzy operation of a set fuzzy algorithm on the current scene picture to generate a first fuzzy picture.
Specifically, the current scene picture is a picture of a current scene, optionally, the current scene picture may be a panoramic picture of the current scene, and further, the current scene picture may be a panoramic picture of the current scene in the virtual environment.
The scene switching event is an event triggering the scene to be switched from the current scene to the target scene, and the event can be the detection of the movement of the user from the current position to the target position, or the detection of the selection of the target position by the user through a mouse, for example, in a street view map, the user can click a specific position in the street view through the mouse to switch the scene in the street view.
The set-up fuzzy algorithm may be any fuzzy algorithm in the prior art, and typically may be a gaussian fuzzy algorithm.
S120, performing fuzzy operation of the set fuzzy algorithm on the target scene picture to generate a second fuzzy picture.
Similarly, the target scene picture is a picture of a target scene, alternatively the target scene picture may be a panoramic picture of the target scene, further the target scene picture may be a panoramic picture of the target scene in a virtual environment.
S130, based on the switching display of the first blurred picture and the second blurred picture, switching between the current scene and the target scene is achieved.
Optionally, based on the switching display of the first blurred picture and the second blurred picture, implementing switching between the current scene and the target scene may include: after the first blurred picture is generated, switching display content from the current scene to the first blurred picture; after the first setting condition is met, switching display content into a second blurred picture; and after the second setting condition is met, switching the display content into a target scene picture, so that the switching of the current scene and the target scene is realized.
The first setting condition may be that after the second blurred image is generated, the first blurred image is displayed for a set time, no movement of the user is detected within the set time, or the like. Similarly, the second display picture may be a second blurred picture after the second blurred picture is displayed for a set time, or no movement of the user is detected within the set time, or the like. Many other ways of implementing the invention will be apparent to those skilled in the art based on the above technical teaching, and the present embodiment is not limited in any way.
To further reduce impact on user vision, so that switching between pictures becomes softer, based on the switching display of the first blurred picture and the second blurred picture, implementing switching between a current scene and a target scene may include:
and based on fading out the first blurred picture, fading in the second blurred picture, and realizing the switching of the current scene and the target scene.
Alternatively, the fade-out of the first blurred picture and the fade-in of the second blurred picture may be achieved by adjusting picture parameters, which may be contrast, color curves, etc.
The fade-out can also be achieved by gradually setting the pixels of the first blurred picture to the pixels of the set color according to the set rule.
For example, the first blurred image is a gray level image of 4*4 pixels, and the preset rule may be that gray level values corresponding to pixels of a first column and a third column in the first row are set to 0, gray level values corresponding to pixels of a second column and a fourth column in the second row are set to 0, gray level values corresponding to pixels of the first column and the third column in the third row are set to 0, and gray level values corresponding to pixels of the second column and the fourth column in the fourth row are set to 0; then, the gradation value of the pixel whose gradation value is not zero in the gradation map is set to 0.
In order to further improve smoothness of the switching of the fade-out and fade-in pictures, based on the switching display of the first blurred picture and the second blurred picture, implementing the switching of the current scene and the target scene may include:
adding a layer mask to the first blurred picture and the second blurred picture;
and fading out the first blurred image and fading in the second blurred image by adjusting the transparency of the layer mask, so as to realize the switching between the current scene and the target scene.

Example two

s210, responding to a scene switching event, and performing fuzzy operation of a set fuzzy algorithm on the current scene picture to generate a first fuzzy picture.
S220, taking the first blurred picture as a background picture layer, taking a gray picture with a set gray value as a foreground picture layer, and adding a picture layer mask for the first blurred picture.
The gray value of the gray picture can be set according to the requirement, and can also be determined according to the picture parameter of the first blurred picture.
For example, when the brightness of the first blurred picture is high, the gray value of the gray picture may be set slightly larger (gray value 0 represents black, 255 represents white); when the brightness of the first blurred picture is low, then the gray value of the gray picture may be set slightly smaller. An effect is achieved by setting the grey picture to be brighter if the first blurred picture is brighter; if the first blurred picture is darker, the gray picture is set to be darker, so that smooth switching of the scene is realized.
S230, taking the second blurred picture as a background picture layer, taking the gray picture as a foreground picture layer, and adding a picture layer mask for the second blurred picture.
Alternatively, the gray value of the gray picture may be determined according to the picture parameter of the first blurred picture and the picture parameter of the second blurred picture.
For example, the average luminance of the first blurred picture is 20% and the average luminance of the second blurred picture is 50%, and the luminance of the gray picture of the foreground layer may be set to (0.2+0.5)/2×100% =35%.
S240, fading out the first blurred image and fading in the second blurred image by adjusting the transparency of the layer mask, so that the switching between the current scene and the target scene is realized.
When the transparency of the layer mask is 0, the background layer is displayed, and when the transparency is 100%, the foreground layer is displayed. Therefore, the first blurred picture can be faded out and the second blurred picture can be faded in by adjusting the transparency of the layer mask.
From the view point of the user, the display effect of the scene switching can be achieved through the steps: responding to a scene switching event in the process of displaying the current scene picture; switching display content from a current scene picture to a first blurred picture, wherein the initial transparency of a layer mask of the first blurred picture is 0, namely, the first blurred picture is in a state; the first blurred picture gradually appears as a gray picture state by adjusting the transparency of the layer mask of the first blurred picture; switching display content into a second blurred picture, wherein the initial transparency of a layer mask of the second blurred picture is 100%, namely the second blurred picture is in a gray picture state; the second blurred picture is gradually presented as a second blurred picture state from the gray picture by adjusting the transparency of the layer mask of the second blurred picture; and switching the display content into the target scene picture. Thereby realizing smooth switching of scenes.
According to the technical scheme, the foreground image layer is set to be a gray image for transition through the gap of switching the current scene into the target scene. Therefore, the problem of short black screen or flickering caused by large brightness difference between the current common picture and the target scene picture is solved.

The blurring operation of the blurring algorithm is set to reduce noise in the current scene picture and the target scene picture and reduce the detail level of the current scene picture and the target scene picture. Therefore, when the first blurred picture and the second blurred picture are used for switching the scenes, the impact of the switching of the two scene pictures on the vision of a user can be reduced, the switching between the pictures becomes softer, and the tearing feeling of the pictures caused by the problems of distortion and the like is weakened.
