In the following, the present invention proposes some preferred embodiments to teach those skilled in the art to implement.
The invention provides a hand-drawn video optimization method and device for offline display, which are used for acquiring a display part for hand-drawn video display in a background picture by creating the background picture for generating an entity picture for offline display, then matching the display part with an actual display part of the entity picture,
and performing animation processing on the obtained display part material to obtain a hand-drawn video, and then selecting a proper hand-drawn video display device to be embedded into the actual display part in the entity diagram. The method enables the user to realize the offline display of the hand-drawn video without adopting expensive display equipment, thereby greatly reducing the display cost.
Example one
Referring to fig. 1, the present embodiment provides a method for optimizing a hand-drawn video for offline display, which includes the following steps:
s1, creating a background graph for generating the entity graph displayed offline;
s2, obtaining a display part used for displaying the hand-drawn video in the background picture;
s3, matching the display part with the actual display part of the entity graph;
and S4, acquiring the display part material, performing animation processing to obtain the hand-drawn video, wherein the hand-drawn video is used for being displayed on display equipment, and the display equipment is matched with the actual display part.
Example two
Referring to fig. 2, correspondingly, the present embodiment provides a hand-drawn video optimization apparatus for offline display, including:
1. the creating module is used for creating a background image used for generating an entity image displayed offline;
2. the acquisition module is used for acquiring a display part used for displaying the hand-drawn video in the background picture;
3. the matching module is used for matching the display part with the actual display part of the entity graph;
4. and the processing module is used for acquiring the material of the display part to carry out animation processing to obtain the hand-drawn video, wherein the hand-drawn video is used for being displayed on display equipment, and the display equipment is matched with the actual display part.
Technical effects show that after the hand-drawn video is created at present, two on-line and off-line propaganda distribution ways exist. For the offline publicity approach, especially for large-screen display scenes, the cost of the display is too high due to the large screen size and resolution, and meanwhile, the cost of the hand-drawn video is very high due to the high requirements on the resolution of the hand-drawn video and the size of the animation picture.
It should be noted that, when the hand-drawn video is displayed offline, if the large screen is used for demonstration directly, the large screen cannot be directly applied due to factors such as the space of the offline display, the power supply equipment and the like. Therefore, when the method provided by the invention is applied to the offline display of the hand-drawn video, the large screen is not required to be directly used for displaying, but the display is realized in a way that the entity background picture is embedded into the screen, so that the part of the entity background picture which needs to be animated is displayed by using the hand-drawn video, and the entity background picture is more vivid and concrete by embedding the hand-drawn video.
For example, when a "clear river at the river top" is displayed offline at an exhibition, the "clear river at the river top" is animated, and a hand-drawn video directly making the "clear river at the river top" requires a large-sized display for display, which is too expensive.
However, not all areas on the "clear river map" need to be animated, for example, houses, trees and farmlands may not be animated, these elements may be directly displayed by the created static solid map, and the elements in the map such as "farm cattle cross street", "official sedan, and" sailing boat cross bridge "may be animated. For example, animation processing is performed on the part of sailing ship crossing bridge in the 'riverside scene at Qingming festival', namely the part of the 'sailing ship crossing bridge' in the picture can be marked when the scene graph of the 'riverside scene at Qingming festival' is edited, and then a hand-drawn video capable of showing the 'sailing ship crossing bridge' is made. When the entity map is produced, the part marked in the scene map is hollowed out, and then the produced hand-drawn video is stored in corresponding display equipment, wherein a display of the display equipment can be just fittingly embedded with the hollowed-out part in the entity map of the 'Qingming Shang river map'.
It should be noted that step S1, step S2, step S3 and step S4 are creatively combined into an integral technical means which is inseparable, and a background diagram marked with a hand-drawn video display part is formed. In step S1, a background map for the entity map for offline display is created, and the real form of the entity map can be controlled by implementing the editing background map. Step S2 obtains a display portion for displaying the hand-drawn video in the background image, so as to accurately locate which portions of the background image are to be animated. Step S3 is to create an edited background image, and the created background image is marked with an area for embedding the hand-drawn video display portion, thereby facilitating subsequent hollow processing. Step S4 is to obtain the material of the display part for animation processing, to achieve the effect of animation processing on the local display part in the background image, and to generate the hand-drawn video, to achieve the technical effect of embedding the manufactured hand-drawn video display device into the background image.
EXAMPLE III
Referring to fig. 3, in detail, step S2 includes:
s20, configuring the resolution of the background image to determine the definition of the entity image display;
s21, configuring the size of the background image to determine the area shown by the entity image.

20. the first configuration unit is used for configuring the resolution of the background image so as to determine the definition of the entity image display;
21. and the second configuration unit is used for configuring the size of the background image so as to determine the area displayed by the entity image.
Technical effects the resolution and size set when editing the background map determine the definition and size of the entity map created from the background map. If the large screen is directly adopted to display the hand-drawn video, the resolution of the hand-drawn video is limited by the configuration of the large screen, and the higher the resolution, the better the display effect of the large screen, however, the higher the cost is required. And the solid graph is adopted as the method for displaying offline, and even if the resolution of the solid graph is set to be high, the cost is much lower relative to the large screen.
EXAMPLE five

30. the first acquisition unit is used for acquiring the number of display areas used for displaying the hand-drawn video in the background picture;
31. the second acquisition unit is used for acquiring the display area position used for displaying the hand-drawn video in the background picture;
32. and the third acquisition unit is used for acquiring the size of a display area for displaying the hand-drawn video in the background image.
EXAMPLE seven
Referring to fig. 7, in detail, step S4 includes:
s40, matching the display area number with the actual display area number of the entity graph;
s41, matching the display area position with the actual display area position of the entity graph;
and S42, matching the display area size with the actual display area size of the entity diagram.
