Object end positioning method and applied system thereof

Abstract

The invention relates to an object end positioning method, which is used for positioning the end position of two members of an object. A foreground image is obtained by proceeding foreground treatment of an obtained original image. The foreground image corresponds to the outline of the object in the original image. A plurality of turning points are obtained according to the foreground image and are linked to form a polygonal curve which is similar to the outline of the object. The turning points are classified into convex points or concave points according to an angle of the turning point, and a plurality of convex points to be selected and a plurality of concave points to be selected are selected. Two of convex points to be selected are selected to be used as two temporary end points. The two temporary end points are linked with a concave point to be selected which is arranged between the two temporary end points to form a triangle corresponding to the two members of the object in the original image. Two positioning end points are determined according to the two temporary end points so as to position the end position of the two members of the object.

Description

technical field [0001] The present invention relates to an object endpoint positioning method and an applied system, and in particular relates to an object endpoint positioning method and an applied system for locating the end positions of two limbs of an object. Background technique [0002] A human-computer interaction interface is an interface that allows a human to interact with a computer. Generally speaking, the human-computer interaction interface usually includes a keyboard, a mouse, or a touch panel. In such an interface, a person is called a user. Through the human-computer interaction interface, the user can achieve the purpose of controlling the computer or interacting with the computer. [0003] In the patent disclosed in US Patent No. 5,524,637, an interactive system for measuring physiological exercise ("interactive system for measuring physiological exercise") is proposed, which is to wear an acceleration sensor (accelerometer) on the user's feet , and mak...

AI Technical Summary

Problems solved by technology

[0005] Although a variety of human-computer interaction interfaces have been proposed, in the above-mentioned embodiments, if the user-computer interaction interface is to be able to determine the end positions of the user's feet, the user must wear a special device or Clothing (such as the above-mentioned acceleration sensor, and signs)

In this way, it will cause inconvenience to the user, and may also reduce the user's willingness to use
