A kind of indirect measuring method, the elastic film and the application of the elastic film using the method

Abstract

The invention discloses an indirect measurement method, an elastic membrane using the method and an application of the elastic membrane. The elastic membrane is provided with marks such as points, circles or grids at equal intervals; the method comprises the following steps: covering a measured object with the elastic membrane, and indirectly measuring the measured object by measuring the elasticity change ratio of the marks on the elastic membrane. By adopting the method, the surface size of the measured object can be simply, conveniently and effectively measured; by using the elastic membrane as a straitjacket, human body types can be measured or detected, for example, the weight-lose effects of an abase patient in different periods in the weight-lose process can be detected, and a bodybuilder can quantize exercise modes and the like by acquiring size parameters of different parts of the body.

Description

technical field [0001] The invention relates to an indirect measuring method, an elastic membrane using the method and an application of the elastic membrane. Background technique [0002] Indirect measurement methods are often used in size measurement. The general method is to shoot the scale of the ruler at the same time during the shooting of the graphics, so that the actual size of the photographed object can be known according to the proportional relationship. For example, when taking footprints Put the ruler on the side so that you can know the size of the shoe that forms this footprint based on the scale. There is also a similar method, which is used when photographing samples through a microscope, that is, under the same magnification, first photograph the scale, record the ratio in the graphic analysis software, and directly call the ratio through the software when measuring the sample. In this way, parameters such as length and area can be measured very convenient...

AI Technical Summary

Problems solved by technology

[0003] There are many limitations in the above measurement methods, for example, the sample may be partially covered during the measurement (for example, when measuring an apple on a tree, the apple may be partially covered by leaves, and the complete outline cannot be photographed)

Another example is the measurement of the human body. It is impossible to accurately estimate parameters such as waist circumference and bust circumference on photos or images, and only outline dimensions such as height can be estimated.
