OBSTACLE DETECTING SYSTEM AND METHOD
First Claim
1. An obstacle detecting system comprising:
- a first image acquiring unit which acquires first image information by selectively receiving a laser beam emitted from at least one laser source toward a road surface at a target distance;
a second image acquiring unit which acquires an image of actual surroundings as second image information;
an image recognizing unit which recognizes an image of an obstacle by performing 3-D image recognition signal processing on line information of the laser beam using the first image information, and recognizes a pattern of the obstacle by performing pattern recognition signal processing on the second image information; and
a risk determining unit which classifies the recognized obstacles according to whether or not the image-recognized obstacle is matched with the pattern-recognized obstacle, and determines a possibility of collision due to presence of the obstacle within the target distance.

Abstract
The obstacle detecting system includes a first image acquiring unit which acquires first image information by selectively receiving a laser beam emitted from at least one laser source toward a road surface at a target distance; a second image acquiring unit which acquires an image of actual surroundings as second image information; an image recognizing unit which recognizes an image of an obstacle by performing 3-D image recognition signal processing on line information of the laser beam using the first image information, and recognizes a pattern of the obstacle by performing pattern recognition signal processing on the second image information; and a risk determining unit which determines a possibility of collision due to presence of the obstacle within the target distance by classifying the recognized obstacles according to whether or not the image-recognized obstacle is matched with the pattern-recognized obstacle.

10. An obstacle detecting method comprising:
-
scanning a laser beam on a road surface at a target distance from at least one laser source; selectively receiving the laser beam only to acquire first image information; acquiring an image of actual surroundings as second image information; recognizing a shape of the obstacle by performing 3-D image recognition signal processing on line information of the laser beam using the first image information; recognizing a pattern of the obstacle by performing pattern recognition signal processing on the second image information to; classifying the recognized obstacles by identifying the image-recognized obstacle is matched with the pattern-recognized obstacle or not; and determining a possibility of collision by identifying the obstacle is within the target distance or not, based on the classified result. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
