Method for dynamically setting environmental boundary in image and method for instantly determining human activity

Abstract

The present invention provides a method for dynamically setting an environmental boundary in an image and a method for instantly determining human activity according to the method for dynamically setting the environmental boundary. The method for instantly determining human activity includes the steps of retrieving at least an initial environmental image with a predetermined angle, and calculating a boundary setting equation of an object and an environmental boundary in the initial environmental image; retrieving a dynamic environmental image having the object by using a movable platform, and figuring out a new environmental boundary; determining a human image in the dynamic environmental image, recording retention time of the human image, and determining a human posture; and determining human location according to the environmental boundary in the dynamic environmental image and the human image, and instantly determining the human activity.
