Embodiment 1

[0050] Example 1, such as figure 1 As shown, a method for synthesizing a digitized three-dimensional model of a Jingchu folk tale clay sculpture figure in an embodiment of the present invention, the method includes:

[0051] Step 1, digitally collect videos and pictures of clay sculpture figures in Jingchu folk stories;

[0052] Step 2: Divide the clay 3D model of the clay figure into a skeleton layer, muscle layer, skin layer and clothing layer. The clothing layer is the outermost layer, and the skin layer is composed of flat or curved pieces to simulate the geometric shape of the skin, and the skin layer is surrounded by Around the muscle layer, the bone layer is at the bottom. The bone layer is a bone joint model including multiple joint points. The hip joint of the clay figure is used as the root node, and the two adjacent joint points are the closest to the root node. The joint point of the position is used as the parent node, and the joint point connected under the pare...

Embodiment 2

[0066] Example 2, such as Figure 4 As shown, the present invention also provides a digital three-dimensional model synthesis system for clay figures of Jingchu folk tales, the system comprising:

[0067] The information collection module digitally collects videos and pictures of clay sculpture figures in Jingchu folk stories;

[0068] The geometric modeling module divides the 3D clay model of the clay figure into a skeleton layer, a muscle layer, a skin layer and a clothing layer. Layers surround the muscle layer, and the bone layer is at the bottom. The bone layer is a bone joint model including multiple joint points. The hip joint of the clay figure is used as the root node, and the two adjacent joint points are the closest to the root. The joint point at the node position is the parent node, and the joint point connected under the parent node is the child node. The root node, parent node and child node are connected by bone segments according to the tree hierarchy structu...

Abstract

The invention discloses a Jingchu folktale clay sculpture figure digital 3D model synthesis method, which comprises the steps of: steps 1, acquiring videos and pictures of Jingchu folktale clay sculpture figures in a digitalized manner; step 2, carrying out layered clay sculpture 3D model geometric modeling, wherein the modeling process can be divided into feature point extraction, surface grid model acquisition, bone creation, skin covering, standard template matching, 3D model calibration, 3D model adjustment and 3D model output; step 3, carrying out clay sculpture 3D model behavioral modeling, and determining attitudes of clay sculpture figures in the process of movements; step 4, reconstructing 3D attitude based on attitude capturing; step 5, and constructing a Jingchu folktale clay sculpture figure resource base. The invention further provides a Jingchu folktale clay sculpture figure digital 3D model synthesis system. The beneficial effects of the method and the system provided by the invention are that: a 3D scanning instrument or a stereoscopic depth video camera is not needed, the modeling is low in cost and fast in speed, the operability is high, the modeling accuracy is improved, the effect is more realistic and vivid, and modification is convenient.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and system for synthesizing digital three-dimensional models of clay sculpture figures in Jingchu folk stories. Background technique [0002] At present, there is a major demand around the digital protection and sharing of Jingchu cultural heritage. Through the collection of diverse Jingchu cultural resources, it is used to study and integrate the digital collection, expression, display and dissemination of cultural heritage. The manifestations of traditional cultural heritage include cultural relics, architecture, and crafts and skills such as costumes, props, and actions, and their digitization mainly uses traditional digital technologies such as photography and video. Jingchu folk story clay figures are typical representatives of Jingchu cultural heritage. Traditional digital technology can no longer meet the innovative development of cultural heritage. There...
