Embodiment Construction

[0039] Start the scanning device, and when the human body under test walks into the center of the test platform (8 in the figure), the depth cameras on the 4 brackets will collect images and depth information in 4 directions, and adjust the depth camera according to the ambient light. To fill in light, turn on the LEDs (502 in the figure) to fill in the light, and the data in 4 directions are generated on the data acquisition main board (10 in the figure) and then transmitted to the modeling host (11 in the figure) through the network. The modeling process Through the touch screen to interact with the user (7 in the figure), the modeling status is displayed synchronously. After collecting data from each part multiple times, the actual parameters after measurement are removed by symmetrical contrast and fuzzy modeling methods based on big data and pre-set parameters. After the thickness and clothing folds are modeled, during the acquisition process, the non-fitting part of the h...

Abstract

The invention provides a device for acquiring three-dimensional data of a human body by adopting a backside illuminated CMOS sensor. A high-definition CCD sensor is adopted to carry out three-dimensional model coloring. SOC FPGA is used for collecting and synchronizing all three-dimensional and planar image information at a high speed. Four sets of same acquisition devices are used for acquiring three-dimensional and color data of the human body in four directions. A ground weight scale and a capacitive touch sensor are adopted to carry out human body weighing and foot bottom three-dimensionalscanning. The invention provides a human body high-frame-rate three-dimensional scanning device adopting back-illuminated CMOS. Rapid three-dimensional scanning can be realized multiple times in themoving process of the human body. The external shape can be manually corrected in the scanning process. Modeling is carried out according to a symmetric comparison fuzzy modeling method. so that the accuracy and practicability of final human body actual modeling after scanning are improved. Data splicing and 3D modeling are carried out at a PC terminal. A complete 3D model is finally output. Oarameter information needed by various kinds of needed clothes is generated, and the parameter information is transmitted to a server to be stored.

Description

technical field [0001] The invention relates to the technical field of three-dimensional measurement, in particular to a human body high-frame-rate three-dimensional scanning device and 3D modeling technology using back-illuminated CMOS sensor technology. Background technique [0002] CMOS (Complementary Metal-Oxide-Semiconductor), the Chinese name is Complementary Metal-Oxide-Semiconductor, it is an important chip in the computer system, and it saves the most basic information of the system boot. The manufacturing technology of CMOS is no different from that of general computer chips. It mainly uses semiconductors made of two elements, silicon and germanium, so that N (charged) and P (charged) levels coexist on CMOS. In semiconductors, the current generated by these two complementary effects can be recorded and interpreted as an image by the processing chip. Later, it was discovered that CMOS can also be used as an image sensor in digital photography after processing. CM...
