20140139674 | IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD - An image processing apparatus includes an image obtaining section for obtaining images from cameras on a moving object; a correspondence processing section for generating a correspondence between characteristic points extracted from a pair of images before and after the moving object moves straight; a height/orientation estimating section for estimating orientations and heights of the cameras, by estimating a homography matrix from the corresponded characteristic points, then decomposing the homography matrix, and using the decomposition result, a movement direction vector, a road surface normal vector, and a moved amount of the moving object; a projective transform section for applying projective transform to common view parts between the cameras; and a relative position estimating section for estimating a relative position of one of the cameras relative to another one of the cameras using translation for overlapping the common view parts after projective transform. | 05-22-2014 |
20140297059 | VISUAL CONFIRMATION EVALUATING APPARATUS AND METHOD - A visual confirmation evaluating apparatus generates unobstructed state information indicating that a driver in a vehicle at an intersection is in a position capable of visually confirming roads on the right and left. This unobstructed state information is used to evaluate a safety check made by the driver, in order to improve the accuracy of the evaluation. In addition, the visual confirmation evaluating apparatus generates viewing direction information indicating a direction in which the driver of the vehicle should look at the intersection, and an appropriateness of a line of sight of the driver is evaluated using the viewing direction information. | 10-02-2014 |
20140313349 | IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD - An image processing device includes a processor; and a memory which stores a plurality of instructions, which when executed by the processor, cause the processor to execute, acquiring an image that includes a marker that includes a plurality of first color regions and a plurality of second color regions, of which a color is different from a color of the first color regions, the plurality of first color regions being opposed to each other and the plurality of second color regions being opposed to each other; extracting the first color regions or the second color regions from the image; reducing the first color regions or the second color regions until a first degree of similarity between a shape of the first color regions or the second color regions, the first color regions or the second color regions being extracted, and a predetermined elliptical shape satisfies a predetermined first threshold value. | 10-23-2014 |
