20090099767 | Light stripe detection method for indoor navigation and parking assist apparatus using the same - Disclosed is a method for detecting a light stripe for indoor navigation and a parking assist apparatus using the same. The apparatus applies light plane projection to indoor navigation, detects a light stripe from an image inputted through a camera, detects an obstacle, and assists vehicle parking by using an active steering device and an electronically controlled braking device. A light stripe width function is used to calculate a light stripe width, and a half value of the calculated light stripe width is used as a constant value of a LOG filter to conduct LOG filtering and detect the light stripe. The precision and rate of recognition of light stripes obtained by LOG filtering are advantageously improved. Therefore, obstacles are precisely recognized during indoor navigation, and parking is assisted efficiently. | 04-16-2009 |
20090146842 | Method and system for recognizing target parking location of vehicle - Disclosed is a method and a system for recognizing a target parking location of a vehicle. The system includes a scanning laser radar for detecting range data reflected and directed from a rear surface of the vehicle; a preprocessing unit for preprocessing the range data to extract effective clusters; a corner recognition unit for extracting obstacle corners from the effective clusters; and a parking location setting unit for recognizing a main reference corner, which is closest to a subjective vehicle and has an adjacent space satisfying an available parking space condition, and a sub reference corner, which exists toward the adjacent space in a direction opposite to a vehicle width direction from the main reference corner, and corresponds to a point on a closest effective cluster within a distance between a vehicle width and a vehicle length, from the obstacle corners to set a target parking location. | 06-11-2009 |
20090207045 | METHOD AND APPARATUS FOR DETECTING TARGET PARKING POSITION BY USING TWO REFERENCE POINTS, AND PARKING ASSIST SYSTEM USING THE SAME - Disclosed are a method and an apparatus for detecting a target parking position by using two reference points, and a parking assist system using the same. The apparatus includes: a first unit for receiving an input image obtained by photographing a parking space and the two reference points in the input image; a second unit for detecting a target pattern of parking slot markings by using each of the two reference points; and a third unit for detecting the target parking position by using the detected target patterns. | 08-20-2009 |
20090243889 | MONOCULAR MOTION STEREO-BASED FREE PARKING SPACE DETECTION APPARATUS AND METHOD - A monocular motion stereo-based automatic free parking space detection system is disclosed. The system acquires image sequences with a single rearview fisheye camera, three-dimensionally reconstructs the vehicle rearview by using point correspondences, and recovers metric information from a known camera height to estimate the positions of adjacent vehicles thereby detecting the free parking spaces. By using de-rotation-based feature selection and 3D structure mosaicking the degradation of the 3D structure near the epipole is solved and it is not necessary to use the unreliable odometry due to its accuracy depending on road conditions. | 10-01-2009 |
20090303026 | APPARATUS, METHOD FOR DETECTING CRITICAL AREAS AND PEDESTRIAN DETECTION APPARATUS USING THE SAME - An apparatus, method for detecting critical areas and a pedestrian detection apparatus using the same are provided. An application of the pedestrian detection system is provided to help limit critical urban environment to particular areas. Contrary to traditional pedestrian detection systems that localize every pedestrians appearing in front of the subject vehicle, the apparatus first finds critical areas from urban environment and performs a focused search of pedestrians. The environment is reconstructed using a standard laser scanner but the subsequent checking for the presence of pedestrians is performed by incorporating a vision system. The apparatus identifies pedestrians within substantially limited image areas and results in boosts of timing performance, since no evaluation of critical degrees is necessary until an actual pedestrian is informed to the driver or onboard computer. | 12-10-2009 |
20130265429 | SYSTEM AND METHOD FOR RECOGNIZING PARKING SPACE LINE MARKINGS FOR VEHICLE - Disclosed is a system and method for recognizing a parking space line marking for a vehicle. In particular, a corner capturing process is configured to capture an angled corner in an image including the parking space line marking, and a cross capturing process is configured to capture a cross point by combining adjacent corners among the captured corners. A space capturing process captures a space which is an end periphery of the parking space line marking by combining the captured cross points. As a result of the above processes, a type selecting process can then select a type of the parking space line marking from the captured space, and a final selection process may select a final space based on the selected type. | 10-10-2013 |
20140112542 | SYSTEM AND METHOD FOR RECOGNIZING PARKING SPACE LINE MARKINGS FOR VEHICLE - Disclosed herein is a method for recognizing a parking space line marking for a vehicle, including: detecting, by a processor, a plurality of parking spaces from a portion of a parking space line marking in an image; calculating, by the processor, an overlap coefficient representing a degree of overlapping between the detected parking spaces; selecting, by the processor, a parking space having a largest brightness coefficient as a final parking space by determining overlap when the overlap coefficient has a predetermined magnitude and comparing the brightness degrees of the overlapped parking spaces. | 04-24-2014 |
20140355822 | APPARATUS AND METHOD FOR MATCHING PARKING-LOT OUTLINE - An apparatus and a method for tracing a parking-lot is provided that includes a controller configured to recognize at least one parking-lot from a previous image frame which photographed a surrounding of a vehicle and extract a template according to a type of a parking-lot line of the recognized parking-lot. In addition, the controller is configured to generate a template transformed based on a position information of the parking-lot and calculate similarity by comparing a template generated from a previous image frame with a parking-lot line recognized from a current image frame. A position of a parking-lot is determined according to the calculated similarity and the controller is configured to correct the template based on an information of a parking-lot line extracted from the determined position. | 12-04-2014 |
