Object endpoint positioning method and application system

Abstract

An object end point positioning method is used for locating the end positions of two limbs of an object. In this method, foreground processing is performed on the obtained original image to obtain a foreground image. The foreground image corresponds to object outlines in the original image. A plurality of turning points are obtained according to the foreground image, and the turning points are formed online to form a polygonal curve close to the outline of the object. Each turning point is classified into a convex point or a concave point according to an included angle, and a plurality of selected convex points and a plurality of selected concave points are selected. Select the second of the selected bumps as the two tentative endpoints. The connection of the selected two tentative endpoints and a selected concave point between the two tentative endpoints forms a triangle corresponding to the two limbs of the object in the original image. The two positioning endpoints are determined according to the two tentative endpoints to locate the end positions of the two limbs 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
