Problems solved by technology

[0006] However, the existing technology has a relatively limited ability to identify human body feature points, which is prone to misjudgment. Therefore, it is still necessary to use manual assistance to identify human body feature points, and automatic measurement cannot be achieved.
In addition, in the prior art, the measurement step and the calibration step need to be implemented separately, and then the data obtained in the two steps are combined for calibration processing, so the difficulty of image calibration becomes greater and the accuracy is also limited
These two deficiencies limit the further popularization and application of computer vision-based non-contact human body measurement technology

Embodiment Construction

[0052] figure 1 It is a schematic diagram of the components of the non-contact measurement system for human body dimensions. The system includes a shooting room, an image generator, and an image processor. The shooting room is a closed or semi-open space for shooting human body images. The image generator is a device for photographing people to obtain two-dimensional images of the human body. The image processor is a processor pre-stored with a specific human body feature point algorithm.

[0053] During the measurement, the human body stays in the shooting room in a standing or sitting position, and is photographed by the image generator, so as to obtain at least a two-dimensional human body image including front and side. In the two-dimensional image, the inventor preset several marker points in the background as marker points for calibrating the image generator (also referred to as calibration marker points). In this way, the marked point is naturally included in the ca...

Abstract

The invention provides a measurement method of automatically acquiring outline dimension of human body by shooting human body image with an image acquisition device and analyzing the image through specific algorithm, and relates to a measurement system for implementing the non-contact measuring method. In the invention, a human body is in a shooting room, a two-dimensional image of the human body is acquired by an image generator, and the image generator processes the two-dimensional image, generates three-dimensional characteristic points of the human body and eventually calculates the needed human body figure data according to the three-dimensional characteristic points of the human body. Compared with the prior art, the invention directly arranges the marking points for calibrating on a background wall, processes specific algorithm by means of designing a large amount of images and provides a technical proposal that can realize fully automatic physical measurement of the human body, thereby significantly simplifying complicacy of the device and the operation and increasing the consistency and accuracy of the measurement.

Description

technical field [0001] The present invention relates to a non-contact measurement method and measurement system for the external dimensions of the human body, in particular to a method for measuring the external dimensions of the human body by taking images of the human body with an image acquisition device and analyzing the images with a specific algorithm, and also relates to a method for implementing the non-contact measurement method. The invention relates to a measuring system of a contact measuring method, which belongs to the technical field of computer vision. Background technique [0002] In many fields such as clothing design, clothing tailoring, construction engineering, ergonomics, etc., obtaining the precise shape and size of a specific individual or group is one of the basic prerequisites for carrying out work. Especially in the field of clothing tailoring, since the size of the clothing must match the shape of the person, and there are obvious individual diffe...
