PURPOSE: An intrusion sensing method and a system thereof are provided to sense intrusion by using the change of a lattice pattern without using a separate lighting part. CONSTITUTION: A lighting part(110) irradiates a lattice image to a target object. A camera(130) obtains an image which takes a photograph of the target object. An image processing part(140) calculates the size change of a lattice which is irradiated to the target object by analyzing the image. The image processing part estimates the size of an invasion object based on the amount of a size changed. A central processing part(150) determines whether intrusion is generated according to the invasion object. A lighting control part(120) controls the location of the lighting part and the lighting intensity of the device according to the distance between the target object and the lighting part. |
