Detailed Description

The present invention will be described in further detail with reference to the attached drawings, but the present invention is not limited thereto.

A method for measuring the chest circumference and waist circumference of a human body based on a random optimizing strategy comprises the following steps:

s1, starting the camera through the mobile phone (tablet personal computer or other mobile terminal equipment);

s2 the measurer wears the special measuring clothes;

s3, starting a camera by a mobile phone (a tablet personal computer or other intelligent mobile terminal equipment) to shoot the front and the side of a measurer, and storing the pictures on the shooting equipment;

s4, taking a photo of the measurer through a mobile phone (a tablet personal computer or other intelligent mobile terminal equipment), and uploading the photo to a server or a cloud server through a communication technology (wired/wireless internet);

The body measurement properties in step S2 are as follows:

1) the body measuring clothes are made of elastic close-fitting clothes, and the elastic capability is outstanding enough, so that the body measuring clothes are suitable for most people. The fabric color can be brown, black or other dark colors.

2) Two non-retractable white circles made of special materials are arranged at the positions 2.5-4.5 cm away from the central line of the measuring body garment and the distance from the neckline to the lower part is 22% -27% of the length of the measuring body garment, the diameter range of the two white circles can be set to be 1-5 cm, and a straight line formed by the centers of the two circles can be perpendicular to the central line of the measuring body garment. The white circles are permanently attached to the front side and the back side of the body measuring clothes through different clothes manufacturing processes, and a circular ring formed by the four circles on the front side and the back side is perpendicular to the central line of the front side and the back side of the body measuring clothes.

3) Two non-retractable white circles made of special materials are arranged at the positions 2.5-4.5 cm away from the central line of the measuring body garment and the distance from the bottom of the measuring body garment to the upper side is 22% -27% of the length of the measuring body garment, the diameter range of the two white circles can be set to be 1-5 cm, and a straight line formed by the centers of the two circles can be perpendicular to the central line of the measuring body garment. The white circles are permanently attached to the front side and the back side of the body measuring clothes through different clothes manufacturing processes, and a circular ring formed by the four circles on the front side and the back side is perpendicular to the central line of the front side and the back side of the body measuring clothes.

In step S3, the front and the side of the upper body of the measurer are photographed by using a camera on a mobile phone (tablet computer or other intelligent mobile terminal device). Under the condition that a measurer and a background environment meet a certain condition, the camera is enabled to be parallel to the measurer, and front photographing is achieved. After the front photographing is finished, the camera position and the position of the measurer are kept unchanged, and the measurer rotates by 90 degrees to perform side photographing.

As shown in fig. 1 and 2, the specific flow in step S5 is as follows,

1) through an image analysis technology, binarization processing of the photo is realized on a back-end (cloud) volume measuring platform;

2) fitting human body into an ellipse, establishing a coordinate system, and respectively obtaining the long axis a of the initial ellipse in the front photograph and the side photograph₀Minor axis b₀The intersection point of the long axis and the short axis is taken as a coordinate axis dot (0, 0);

3) through an artificial intelligence technology, the identification and positioning of mark points of the volume measuring clothes in the photo are realized on a back-end (cloud) volume measuring platform, and the x coordinate x of the mark points is obtained in the front image after binaryzation₀Acquiring the y coordinate b of the mark point in the binarized side view₀；

4) Obtaining the arc length l 'from the mark point to the top point of the ellipse by a circle cutting method'₀. Using an ellipse perimeter approximation formula: 2 π b +4(a-b) (a, b are respectively the major and minor axes of the ellipse) gives the perimeter l 'of the ellipse'₁；

5) The long axis a obtained in the step 2)₀Minor axis b₀In the above-mentioned step 4), the initial value is obtained

The major axis a 'and the minor axis b' of the ellipse.
