specific Embodiment approach 1
[0035] Specific implementation mode one: the following combination Figure 1 to Figure 5 Illustrate this embodiment, the three-dimensional shadow puppet play production method based on depth perception described in this embodiment, it comprises the following steps:
[0036] Step 1: use the overall image of the shadow play figure to be made as the front view of the three-dimensional model making module, and the front view is used as a reference for the three-dimensional model of the shadow play figure, and the overall image of the shadow play figure to be produced presents 90-degree movements of hands and feet;
[0037] Step 2: Establish a plane model of all body parts of the shadow puppet figure to be made according to the front view;
[0038] Step 3: Carry out surface color mapping on the plane model of all body parts of the shadow puppet figure to be produced;
[0039] Step 4: Adjust the positions of the plane models of all the body parts of the shadow puppet figure to be m...
specific Embodiment approach 2
[0042] Specific embodiment two: this embodiment will further explain embodiment one, the method for obtaining the overall image of the shadow puppet figure to be made in the step 1 is: take and obtain the overall photo of the shadow puppet figure to be made, and use an image processing tool to process the background of the overall photo of the shadow puppet figure to be produced Cut out, and then save it as a png format file as the overall image of the shadow puppet figure to be made.
[0043] The image processing tool in this embodiment can use Photoshop.
specific Embodiment approach 3
[0044] Specific implementation mode three: the following combination Figure 1 to Figure 3 Illustrate this embodiment, this embodiment is described further to embodiment two, and the concrete method of setting up all body part plane models of the figure to be made shadow puppetry in step two is:
[0045] In the three-dimensional model making module, according to the overall image of the shadow puppet figure to be made as the front view of the three-dimensional model making module described in step 1, a new plane model is created, and the parameters of the new plane model are modified to obtain the head crop parts P1 plane model, P2 plane model of upper body, P3 plane model of right upper arm, P4 plane model of right forearm, P5 plane model of right hand, P6 plane model of left forearm, P7 plane model of left forearm, P8 plane model of left hand, P9 plane model of right upper leg, P10 plane model of lower leg, P11 plane model of right foot, P12 plane model of left upper leg, P1...

Abstract
The invention provides a depth perception based three-dimensional shadow play production method, belongs to the technical field of digital shadow play production and aims to solve the problem that the conventional shadow play inheritance mode cannot truly reflect conversion between fiction and fact and cannot be matched with shadow play patterns adaptively. The method comprises the following steps: firstly, the whole image of a to-be-produced shadow puppet is taken as a front view of a three-dimensional model production module so as to serve as a reference for a three-dimensional model of the shadow puppet; plane models of the whole body parts of the shadow puppet are produced; the plane models are subjected to surface color mapping; the plane models of the whole body parts of the to-be-produced shadow puppet are stitched and connected sequentially to form a three-dimensional model of the shadow puppet; the three-dimensional model of the shadow puppet is bound with all bones; a mapping relation between all the bones of the three-dimensional model of the shadow puppet and three-dimensional coordinate information of corresponding human body bones and joints is established; and the bones of the three-dimensional model of the shadow puppet is then controlled to move by a human bone movement sequence. The depth perception based three-dimensional shadow play production method is applied to three-dimensional shadow play production.
Description
technical field [0001] The invention relates to a three-dimensional shadow play production method based on depth perception, and belongs to the technical field of digital shadow play production. Background technique [0002] Shadow puppetry originated in the Han Dynasty and is the earliest screen shadow art for people to watch in the world. Shadow puppet art has experienced thousands of years of development and inheritance. It bears mutual bearing with folk customs and integrates with local traditions and folk culture. Its modeling technique is unique, with special expressive force and formal beauty. It is a traditional rap performance art and folk craft in my country The unique art variety formed by the perfect combination of fine arts was once an important part of people's daily life entertainment. However, with the emergence and rapid development of other art forms and information technology, people gradually get used to obtaining information and interacting with entertai...
