Method for feature recognition in mobile communication terminal
First Claim
1. A portable terminal comprising:
- a Global Positioning System (GPS) configured to provide a position of the portable terminal;
a camera configured to capture an image of a feature;
a sensor configured to detect a direction of the camera;
an image geographic information part comprising image information;
an image processor configured to extract a characteristic of the captured image of the feature and compare the extracted characteristic with image information stored in the image geographic information part; and
a controller configured to proportionally compare, in response to recognizing a specific feature through the image processor, configured to, geographic information of the image information with size and direction data on a peripheral feature near the feature within the captured image, and recognizing the peripheral feature.

Abstract
A portable terminal is configured to perform method for feature recognition. The portable terminal includes a Global Positioning System (GPS), a camera, a sensor, an image geographic information part, an image processor, and a controller. The GPS provides a position of the portable terminal. The camera photographs an image of a feature. The sensor detects a direction of the camera. The image geographic information part stores an image of each feature and geographic information on each feature. The image processor extracts a characteristic of the image of the feature and compares the extracted characteristic with image information stored in the image geographic information part. If recognizing a specific feature through the image processor, the controller proportionally compares geographic information of the image geographic information part with size and direction data on a peripheral feature near the specific feature within an image, and recognizes the peripheral feature.

9. A method for feature recognition in a portable terminal, the method comprising:
-
recognizing a current position of the portable terminal by a Global Positioning System (GPS); photographing an image of a feature by a camera; detecting a direction of the camera using a sensor; extracting a characteristic of the image of the feature photographed by the camera; comparing the extracted characteristic with image information on a feature positioned in a direction of the camera on a position of the portable terminal; and if recognizing a specific feature, comparing geographic information of an image geographic information part with distance and direction data on a peripheral feature near the specific feature within an image, and recognizing the peripheral feature. - View Dependent Claims (10, 11, 12, 13)
