External image sensing system and control method

The present invention relates to an external image detection system, and more particularly, to an external image detection system and a control method thereof to prevent damage and theft by analyzing the frequency of parking and stopping of an automobile.

In general, automobiles have been widely distributed to be a necessity of life, but theft and damage accidents occur frequently in proportion. Therefore, an alarm system and the like have been developed to prevent this, and the system monitors the vehicle through a sensor that can detect a shock applied to the vehicle. That is, when an impact is applied to the vehicle from the outside while the sensor is switched to the monitoring state when the sensor is operated, the sensor detects the impact and generates a warning sound through the horn. In addition, by flashing the emergency car lights to inform the outside that the vehicle is in an emergency.

However, if the owner of the car is not in the place where the car is parked, no evidence could be obtained even if the car sounds an alarm due to damage.

In addition, according to the external image detection system and a control method thereof according to the present invention, since the camera is continuously operated from the point before the impact detection, the effect of knowing the situation at the time of impact can also be obtained.

Briefly, the present invention comprises an impact detecting means, an image photographing means, and an image control means.

In particular, the image control means enables to detect damages such as scratches through a method of recognizing a frequency change due to an external shock as an external shock in order to efficiently monitor the damage of the vehicle during parking and the like.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. In addition, in describing this invention, the same code | symbol is attached | subjected and the repeated description is abbreviate | omitted.

2 is a block diagram briefly illustrating a configuration of an external image sensing system according to an exemplary embodiment of the present invention.

Referring to FIG. 2, the external image sensing system 200 includes an impact sensor 210, a camera 220, and an image controller 230.

The shock sensor 210 is attached to the vehicle and outputs a frequency according to the detection of the impact from the outside, it is preferable to attach to detect all the parts of the vehicle in order to detect the impact in the event, for example For example, it attaches to all sides including front and rear bumpers.

The camera 220 is attached to the vehicle to continuously photograph the peripheral area of the position where the impact sensor 210 is attached from the time before the impact detection, it can be moved or rotated within the set radius.

The image controller 230 outputs a signal (for example, an interrupt signal) that stops the image storing or deleting operation when the change of the image photographed by the camera 220 is also recognized when the external shock frequency is detected. Control to store the external image before and after the image, that is, the image photographed during the first set time before and after the impact point (for example, the image photographed for 5 minutes before and after the detection point). At this time, the stored image is not automatically deleted without the driver's delete command.

In addition, as illustrated in FIG. 2, the external image detection system 200 includes a memory unit 240, a front / rear light 250, and a warning sound output unit 260.

The memory 240 stores an image input from the image controller 230 and stores data for each frequency according to an external shock type. Accordingly, the image controller 230 recognizes the shock frequency as a shock detection through comparison with data for each frequency according to the external shock type (for example, scratch, tire puncture, contact with an external object, etc.) stored in advance. .

In addition, the memory unit 240 repeatedly stores and deletes an image input from the camera 220 at intervals of a second set time (for example, 5 minutes) under the control of the image controller 230. Therefore, it is possible to obtain the effect of knowing the situation of the impact point in detail through the stored image before the impact detection point.

The front / rear light 250 and the warning sound output unit 260 output a flashing operation and a warning sound according to the control signal of the image control unit 230 according to the impact detection. In this embodiment of the present invention, since the warning sound is output only by the control signal, the warning sound output unit 260 outputs a warning sound.

If described in detail with reference to the accompanying drawings the operation process according to an embodiment of the present invention configured as follows.

3 is a flowchart illustrating an operation process of an external image sensing system according to an exemplary embodiment of the present invention.

Referring to FIG. 3, first, a step of monitoring whether a shock from an outside of the vehicle and a change in an input image is sensed is performed (S300 to S320). At this time, the frequency-specific data according to the type of external shock (for example, scratch, tire puncture, contact with an external object, etc.) is stored in the memory 240 in advance, and the input image is set before the shock is detected (for example, Auto save and delete are repeated every 10 minutes).

Subsequently, when the frequency change according to the impact is detected during the monitoring, a step of determining whether the external shock is recognized through comparison with the frequency-specific data according to the stored external impact type is performed (S330). In other words, if the frequency due to scratches, tire punctures, etc. match, the detection frequency is determined as an external shock.

Subsequently, if it is determined as the external impact, a step of determining whether a change in the image is detected is performed (S340). If an external shock is detected but no change in the image is detected, the process returns to the step S310.

If both an external shock and a change in the image are detected, an image of the captured image is stored for a predetermined time (for example, 5 minutes) before and after the impact point after generating an interrupt signal to stop the storage operation or deletion (S350).

At this time, the front and rear lights flashing (for example, 30 seconds flashing) and the warning sound (for example, 30 seconds output) are output so that the image can be recognized from the outside at the same time as storing the image (S360).

As mentioned above, although the invention made by this inventor was demonstrated concretely according to the said Example, this invention is not limited to the said Example and can be variously changed in the range which does not deviate from the summary.

1 is a view showing a concept in which a conventional imaging system is applied to a vehicle.
