20100322478 | Restoration apparatus for weather-degraded image and driver assistance system - In a restoration apparatus, an estimating unit divides a captured original image into a plurality of local pixel blocks, and estimates an luminance level of airlight in each of the plurality of local pixel blocks. A calculating unit directly calculates, from a particle-affected luminance model, a luminance level of each pixel of each of the plurality of local pixel blocks in the original image to thereby generate, based on the luminance level of each pixel of each of the plurality of local pixel blocks, a restored image of the original image. The particle-affected luminance model expresses an intrinsic luminance of a target observed by the image pickup device as a function between the luminance level of airlight and an extinction coefficient. The extinction coefficient represents the concentration of particles in the atmosphere. | 12-23-2010 |
20110227781 | METHOD AND APPARATUS FOR DETECTING ROAD-EDGES - An on-vehicle apparatus detects at least one of right and left edges of a road on and along which a vehicle travels. In the apparatus, acquired is information indicative of a plurality of detection points which are given as a plurality of candidates for the edges of the road viewed forward from the vehicle. Further acquired is information indicative of behaviors of the vehicle. A calculating member calculates, based on the acquired information, every detection point, a plurality of passing positions each indicating a position of each of the detection points to a position of the vehicle provided that the vehicle travels to a position on the road which is located right beside each of the detection points. A road edge obtaining member obtains the edges of the road based on the plurality of passing positions calculated. | 09-22-2011 |
20110235861 | METHOD AND APPARATUS FOR ESTIMATING ROAD SHAPE - An apparatus estimates a shape of a road on which a vehicle travel. The apparatus id mounted on the vehicle. In the apparatus, information indicative of a plurality of detection points is received through transmission and reception of electromagnetic waves. The detection points are given as a plurality of candidates for edges of the road. It is determined whether or not a distance between each detection point and the vehicle is equal to or larger than a predetermined value. A first approximated curve for each detection point having the distance equal to larger than the predetermined value is detected, and a second approximated curve for a detection point having the distance less than the predetermined value is detected. The shape of the road is estimated by merging the first and second approximated curves. | 09-29-2011 |
20120001769 | ROADSIDE DETECTION SYSTEM, DRIVER ASSISTANCE SYSTEM AND ROADSIDE DETECTING METHOD - A roadside detection system installed in a vehicle to detect a roadside of a road on which the vehicle travels includes detection results acquiring means, first edge line detecting means and second edge line detecting means. The detection results acquiring means emits light waves or electromagnetic waves to a target detection region in which an object to be measured is detected and acquires an objective distance and a reflection intensity, for each of separate regions obtained by separating the target detection region into a plurality of divisions. The first edge line detecting means detects a first edge line that is a candidate of a roadside based on each objective distance. The second edge line detecting means detects a second edge line that is a candidate of a roadside based on each reflection intensity. A driver assistance system and a roadside detecting method are also provided. | 01-05-2012 |
