Abstract

The present invention relates to an image intrusion detecting apparatus for an automobile, and more particularly, to minimize power consumption by driving a camera, And more particularly, to a video intrusion detection apparatus and method having a power saving function for determining an intrusion.

Description

TECHNICAL FIELD [0001] The present invention relates to a video intrusion detection apparatus and method having power saving function,

The present invention relates to an image intrusion detecting apparatus for an automobile, and more particularly, to minimize power consumption by driving a camera, And more particularly, to a video intrusion detection apparatus and method having a power saving function for determining an intrusion.

As the penetration rate of automobiles increases, crime against automobiles continues to increase.

As automobile crimes increase, various intrusion detection devices called intrusion detection, theft prevention, burglar alarm, and intrusion alarm device are being applied to automobiles.

In general, the intrusion detection device is driven when the vehicle is not driven by a driver, that is, when the vehicle is turned off and the door of the vehicle is locked, monitoring whether or not the third party intrudes into the vehicle, And notify the driver of the intrusion.

There are various types of intrusion detection devices using pressure, tilt, infrared, and ultrasound. Among them, intrusion detection devices using ultrasonic waves and tilt are the most widely used devices.

An intrusion detection apparatus using a general ultrasonic wave periodically transmits an ultrasonic signal (hereinafter referred to as a "TX ultrasonic wave") and an ultrasonic signal (hereinafter referred to as "reception (RX) ultrasonic wave" (Hereinafter referred to as "transmission / reception time") until the transmitted ultrasonic wave is transmitted and the reception ultrasonic wave corresponding to the transmission ultrasonic wave is received, and measures the transmission / reception time And a phase synchronization method for determining whether an intruding signal is detected by checking a phase difference between the transmitted ultrasound wave transmitted and the received ultrasound wave is mainly used.

In addition, the intrusion detection apparatus of the tilt detection method periodically monitors the tilt of the vehicle, sets the initial tilt value at the start of intrusion detection, that is, the initial tilt value, and sets the reference tilt value and the periodically measured tilt value If the slope value exceeds the reference slope value, the intrusion is detected as an intrusion.

However, the conventional intrusion detection apparatuses such as the inclination and the ultrasonic method have various misoperations due to the internal and external environment of the vehicle.

In order to solve such a problem, there has been developed and applied an image analysis type intrusion detection device using a camera that includes a camera for photographing the inside of a vehicle and analyzes a video shot through the camera to determine whether an intruder intrudes .

However, cameras require a lot of power to capture and analyze images. Since the intrusion detection device operates when the vehicle is turned off, it relies solely on the battery power source. Therefore, when a conventional video intrusion detection apparatus is applied, a battery discharge accident is frequently occurred. Therefore, there is a problem that it is difficult to apply to an automobile an intrusion detection apparatus using an image analysis method using a camera.

An intrusion determining step of determining whether an intruder is present by analyzing the acquired image signal by driving a camera unit to determine whether an intruder is present; And
And an intrusion notification process in which the control unit notifies an occurrence of an intrusion through the intrusion notification unit if it is determined that an intruder is present,
The intrusion determination process includes:
Determining whether a window of the vehicle is open if the controller determines that there is an intrusion possibility by driving the camera unit through the window open determining unit to obtain a video signal and analyzing the obtained video signal;
Determining whether the window is broken or open; determining whether there is an object moving through the ultrasonic sensor unit by turning off the camera unit through the motion object existence determination unit; And
And determining whether there is an intruder by analyzing the image and analyzing whether there is an intruder if the window of the vehicle is open and it is determined that there is a moving object through the moving object existence determining unit An image intrusion detection method having power saving function.
8. The method of claim 7,
The invasion possibility judging process includes:
A vehicle tilt detection step of detecting a tilt change of the vehicle and outputting a tilt detection signal according to a tilt change as an intrusion possibility detection signal; And
And an impact detection step of detecting an impact applied to the vehicle and outputting an impact detection signal corresponding to the impact degree as the intrusion possibility detection signal.
9. The method of claim 8,
The invasion possibility judging process includes:
(B +) supplied from the vehicle battery to the video intrusion device, and outputs a battery power cut-off detection signal to the control unit as the intrusion possibility detection signal when the battery power is cut off and drives the emergency power supply unit The method comprising the steps of: detecting a power-off state of the battery;
8. The method of claim 7,
The intrusion notification process includes:
An alarm generating step of generating an alarm through the alarm sound generating unit of the intrusion notification unit; And
And an intrusion notification step of notifying the intruder to the mobile communication terminal of the driver's mobile communication terminal identification information set in advance through the communication unit of the intrusion notification unit or performing the intrusion notification to the short range wireless communication terminal of the driver at a nearby location Wherein the power saving function has a power saving function.
