Embodiment Construction

[0063] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0064] In the prior art, human body contours, key feature regions and feature points, and human body scanning data cannot be clearly represented, resulting in a large deviation between the obtained image human body data and real human body information.

[0065] 1. The application of the present invention will be further described below in conjunction with specific examples.

[0066] Such as figure 1 , the method for extracting human body characteristic parameters based on image analysis provided by the embodiment of the present invention includes:

[0067] S101: extract the user profile and key feature areas and feature p...

Abstract

The invention belongs to the technical field of human body characteristic parameter identification, and discloses a human body characteristic parameter extraction method and system based on image analysis, and the method comprises the steps: extracting a user contour, a key characteristic region and characteristic points through the photo image processing of a user, and obtaining a key part of user characteristic parameter information; scanning enough human body scanning data in a human body database to obtain a neural network model capable of reflecting human body characteristics; directly generating a neural network model according to the input parameter information of the key parts of the height, the chest circumference, the waistline and the hip circumference, and generating a human body characteristic curve matched with the real human body shape; starting from the photo information of the user, searching a similar human body three-dimensional model matched with the body of the user in a 3D scanning human body database; The back propagation neural network (BP neural network) is used for drawing a three-dimensional human characteristic curve, and human characteristic parameterscan be well extracted through the application of the method.

Description

technical field [0001] The invention belongs to the technical field of human body feature parameter recognition, in particular to a method and system for extracting human body feature parameters based on image analysis. Background technique [0002] As an integral part of computer simulation, 3D human body model has been one of the hot topics in computer graphics research. Computer human body model can construct a highly realistic virtual human body model, which is widely used in clothing CAD, animation production, scene simulation and other fields, and has attracted the attention and research of many scholars. With the development of 3D scanning reconstruction technology and 3D body modeling technology, the computer-aided 3D clothing design system is the integration and integration of 3D body measurement, dimension information extraction, clothing design, virtual fitting, animation simulation, customization, sales and display. comprehensive. The computer-aided 3D clothing...
