Individuation portrait product design method based on control point and control line neighborhood deformation

Abstract

The invention provides an individual portrait product design method based on control point and control line neighborhood deformation. The method comprises the following steps of firstly conducting normalization processing on front face and side face images; extracting human face feature points of the front face and side face images; according to the extracted human face feature points of the images, conducting individual deformation on a standard model, and utilizing a radial base interpolation deformation algorithm to conduct corresponding deformation on other non-feature points; using the supposed neighborhood deformation algorithm based on a control point to conduct optimal designing on a portrait point feature region; and using the proposed neighborhood deformation algorithm based on a control line to conduct optimal designing on a portrait linear feature region. The method can be used for optimizing facial features, a hair style, a body, a clothes point feature region and a clothes linear feature region of the individual portrait product and overcomes the defect that a traditional portrait product is hard to rectify, model similarity is low and a model is hard to be directly used for machining and manufacturing.

Description

technical field [0001] The invention relates to the technique of generating a three-dimensional model by using a two-dimensional image, in particular to an optimal design method of a portrait product based on control points and control lines. The method utilizes industrialized production means to design and numerically control the digital geometric model of a realistic three-dimensional portrait according to the two-dimensional image. Background technique [0002] In response to the fast-growing personalized market demand, modern manufacturing enterprises are gradually developing from single-species, large-volume, and long-cycle to personalized customization services with multiple varieties, small batches, and short cycles. With the transformation of advanced manufacturing technology and the rapid development of the Internet and information technology, a personalized portrait product that reconstructs a 3D model using 2D images of real people has emerged, and this product is...

Chinese patent CN200720011658 discloses a doll composed of photos of the face of the person. The final effect of this method depends to a large extent on the degree of application of the photos, the degree of fit between the grooves on the face of the doll and the real person, and the body is Model doll, not made according to customer photos, its overall lifelike effect is not good

[0007] To sum up, the current portrait products on the market mainly rely on traditional hand-made, such as real pottery puppets, clay figurines, three-dimensional stone sculptures, etc. Once the product is formed, it cannot be modified; moreover, its similarity depends entirely on the experience of the craftsman Accumulation and craftsmanship, product quality is difficult to control

Another kind of portrait products generated by using two-dimensional images is widely used in virtual environments such as animation and film and television. The established three-dimensional models rely on textures or colors such as photos to make up for the shortcomings of low similarity of geometric models, and it is difficult to directly use them in the processing of actual products. manufacture
