Abstract

The present invention relates to a method and device for recognizing a situation based on an image using a template. The present invention provides the device for recognizing a situation based on an image. The device includes a camera unit capturing an image which is divided into a plurality of regions and having a template for each of the regions, the template defining characteristics of each of the regions, and a control unit detecting an object in the image and determining the situation surrounding the object according to the template mapped to the region to which the detected object belongs. In addition, the present invention provides the method of operating the device for recognizing a situation.

Claims

1. An image-based situation recognition device comprising:

a camera unit configured to capture an image, wherein the image is divided into a plurality of regions and each region has a template defining a characteristic of the region; and

a control unit configured to detect an object in the image and determine a situation of the object according to the template mapped to the region including the detected object.

2. The image-based situation recognition device of claim 1, wherein the template defines a type of the object detected in the region.

3. The image-based situation recognition device of claim 2, wherein the control unit detects the object in the region with reference to the type of the object defined in the template.

4. The image-based situation recognition device of claim 1, wherein the template defines a behavioral characteristic of the object detected in the region.

5. The image-based situation recognition device of claim 4, wherein the control unit compares a behavior of the object detected in the region with the behavioral characteristic of the object defined in the template to determine the situation of the object.

6. An image-based situation recognition method comprising:

capturing an image, wherein the image is divided into a plurality of regions and each region has a template defining a characteristic of the region;

detecting an object in the image; and

determining a situation of the object according to the template mapped to the region including the detected object.

7. The image-based situation recognition method of claim 6,

wherein the template defines a type of the object detected in the region, and

wherein the detecting comprises detecting the object in the region with reference to the type of the object defined in the template.

8. The image-based situation recognition method of claim 6,

wherein the template defines a behavioral characteristic of the object detected in the region, and

wherein the determining comprises comparing a behavior of the object detected in the region with the behavioral characteristic of the object defined in the template to determine the situation of the object.
