Problems solved by technology

[0002] With the society's increasing demand for comprehensive collection of human biometric information, foot length measurement is becoming a basic human body information measurement link, because the usual foot length measurement is usually to fix the foot to be measured first and then manually read the scale value , so the measurement efficiency is low. If the automation of this measurement process can be realized, the work complexity of the inspectors will be reduced to a certain extent. Therefore, it is positive to introduce a convenient automatic foot length measurement method.

Embodiment Construction

[0082] In order to obtain the foot image, theoretically, it can be taken from three angles: from the top of the head down, from the bottom of the foot vertically up, and from the side obliquely down. In the images taken from the front of the head downwards, a large area of ​​the feet will be covered by the head or body. According to the remaining foot images, it is often not enough to construct the foot contour, and the foot length data cannot be obtained, or the obtained The empirical component in the foot length data is too large to be accurate enough.

[0083] Shooting from the bottom of the foot upwards, the theoretically obtained foot image has no obvious deformation. However, the camera or lens will be required to be placed in the measurement platform for people to stand; the surface of the platform will also be required to use transparent materials so that the feet can be photographed; in addition, the issue of light compensation is often considered. Even with such a h...

Abstract

The invention provides a method for measuring foot length. The method includes acquiring a foot image which comprises a plurality of parallel scale lines with the radial direction of the foot intersected with the scale lines, conducting edge enhancement and binaryzation processing on the image, determining an interested area, acquiring two end points of the foot in the interested area and calculating foot length according to the two end points and the scale lines. A system for measuring foot length is further provided. Compared with the prior art, the method and the system achieve automation of the foot length measuring process by arranging an image analysis module and conducting machine processing, analysis and calculating on the foot image, and reduce manual operation quantity accordingly. In addition, arrangement of the scale lines enables image scaling proportion to be reacted through change of the scale lines. Simply, the foot length can be directly determined according to the multiple relation between the foot length and unit scale.

Description

technical field [0001] The invention relates to a foot length automatic measuring system and method. Background technique [0002] With the society's increasing demand for comprehensive collection of human biometric information, foot length measurement is becoming a basic human body information measurement link, because the usual foot length measurement is usually to fix the foot to be measured first and then manually read the scale value , so the measurement efficiency is low. If the automation of this measurement process can be realized, the work complexity of the inspectors will be reduced to a certain extent. Therefore, it is positive to introduce a convenient automatic foot length measurement method. [0003] Therefore, it is necessary to provide a foot length automatic measuring method and system. Contents of the invention [0004] The purpose of the present invention is to propose a foot length measurement method and an automatic foot length measurement system suit...
