Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] Such as figure 1 Shown, the present invention comprises the following steps:

[0033] Step 1. Take pictures: Take two pictures of foot shapes with your mobile phone according to the following requirements:

[0034] The first picture: Prepare A4 white paper, dark background, dark socks; place A4 white paper on a dark background, put on dark socks and put your feet on the A4 white paper so that the heel is in line with the A4 white paper Align with one short side of the foot; shoot down from the upper center of the instep, so that the edge of the A4 white paper is as flush as possible with the edge of the photo;

[0035] The specification of standard A4 white paper is 210mm*297mm, stepping on the A4 white paper is like stepping on a scale. Since it is stipulated that the heel should be aligned with one side of the A4 white pap...

Abstract

The invention discloses a foot shape data acquisition method based on pictures. The method comprises five steps of picture shooting, picture pretreatment, foot length and width calculation, tarsus height calculation and shoes selecting and coupling. Firstly, two foot shape pictures are shot and pretreated to extract foot shape contour data; according to two sets of the foot shape contour data, the foot length, the foot width and the front tarsal bone bump height are calculated respectively to obtain corresponding foot shape parameters; and finally, according to data of the gender, age and foot shape parameters of a user, coupling with the brand and pattern of some pair of shoes on an online mart is conducted to recommend the optimal size for the user. The invention can conveniently and rapidly extract the foot shape data, can accurately perform size coupling of shoes of different brands and types according to the foot shape data, and can greatly improve the online shoes purchasing experience and reduce the rate of returns as the user selects unsuitable sizes in online shopping. The method is advantaged by simple operation, convenient usage and low cost.

Description

technical field [0001] The invention relates to a data acquisition method, in particular to a picture-based foot shape data acquisition method. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for wearing shoes, and pay more attention to the health and comfort of wearing shoes. However, what is incompatible with this is that people do not have a comprehensive understanding of their foot shapes, and often cannot buy shoes that are suitable for them. In addition, with the popularity of online shopping, more and more people choose to buy shoes online, but because of inappropriate shoe styles or sizes, the return rate has remained high. At present, the existing ways to obtain foot shape data include infrared laser scanning equipment and structured light scanning equipment, but these two equipments have the defects of bulky structure, large cost, high cost and complicated operation, which makes them not suitable f...
