Abstract

The present invention relates to a monitoring method and a monitoring apparatus using a camera. According to an embodiment of the present invention, a monitoring method using a camera includes receiving a photographed input image from the camera; detecting an object existing in the input image and positional information of the object; generating a corrected image by correcting a distorted area of the input image; and generating a synthesized image by synthesizing alarm display information which is generated on the basis of the object and the positional information, with the corrected image, and outputting the synthesized image through a display.

Claims

1. A monitoring method using a camera, comprising:

receiving a photographed input image from the camera;

detecting an object existing in the input image and positional information of the object using the center of the input image as reference;

generating a corrected image from which information on the object existing in a distorted area is removed by correcting the distorted area of the input image; and

generating a synthesized image by synthesizing alarm display information including information on the object existing in the distorted area which is generated on the basis of the object and the positional information, with the corrected image, and outputting the synthesized image through a display.

2. The monitoring method according to claim 1, wherein the alarm display information includes at least one of an alarm image and an alarm text.

3. The monitoring method according to claim 1, wherein the alarm display information is displayed an area, which corresponds to the positional information, in the corrected image.

4. The monitoring method according to claim 1, wherein the detecting the positional information of the object includes:

dividing the input image into multiple areas which are set in advance; and

searching for a pedestrian or an obstacle by detecting a peripheral area other than a central area, among the divided multiple areas.

5. The monitoring method according to claim 1, further comprising:

measuring time of an ultrasonic signal which is transmitted to the detected object and returns, using an ultrasonic sensor; and

detecting information on a distance between the object and a vehicle, based on the measured time.

6. A monitoring apparatus using a camera, comprising:

an input unit which receives a photographed input image from the camera;

an object detection unit which detects an object existing in the input image and positional information of the object using the center of the input image as reference;

a distorted image correction unit which generates a corrected image from which information on the object existing in a distorted area is removed by correcting the distorted area of the input image; and

a synthesized image output unit which generates a synthesized image by synthesizing alarm display information including information on the object existing in the distorted area which is generated on the basis of the object and the positional information, with the corrected image, and outputting the synthesized image through a display.

7. The monitoring apparatus according to claim 6, wherein the alarm display information includes at least one of an alarm image and an alarm text.

8. The monitoring apparatus according to claim 6, wherein the alarm display information is displayed an area, which corresponds to the positional information, in the corrected image.

9. The monitoring apparatus according to claim 6, wherein the object detection unit divides the input image into multiple areas which are set in advance, and searches for a pedestrian or an obstacle by detecting a peripheral area other than a central area, among the divided multiple areas.

10. The monitoring apparatus according to claim 6, wherein the object detection unit measures time of an ultrasonic signal which is transmitted to the detected object and returns, using an ultrasonic sensor, and detects information on a distance between the object and a vehicle, based on the measured time.
