The environment recognition device includes: a position information obtaining unit that obtains position information of a target portion in a detection area, the position information including a relative distance to a subject vehicle; a grouping unit that groups the target portions as a target object based on the position information; a luminance obtaining unit that obtains a luminance of an image of the target object; a luminance distribution generating unit that generates a histogram of the luminance of the image of the target object; and a floating substance determining unit that determines whether or not the target object is a floating substance based on a statistical analysis on the histogram. | 11-22-2012 |
20120294485 | ENVIRONMENT RECOGNITION DEVICE AND ENVIRONMENT RECOGNITION METHOD - There are provided an environment recognition device and an environment recognition method. The device obtains position information of a target portion in a detection area, including a relative distance from a subject vehicle; groups continuous target portions into a target object of which position differences in a width direction vertical to an advancing direction of the vehicle and in a depth direction parallel to the advancing direction fall within a first distance; determines that the target object is a candidate of a wall, when the target portions forming the target object forms a tilt surface tilting at a predetermined angle or more with respect to a plane vertical to the advancing direction; and determines that the continuous wall candidates of which position differences in the width and depth directions among the wall candidates fall within a second predetermined distance longer than the first predetermined distance are a wall. | 11-22-2012 |
20130177205 | EXTERIOR ENVIRONMENT RECOGNITION DEVICE AND EXTERIOR ENVIRONMENT RECOGNITION METHOD - There are provided an environment recognition device and an environment recognition method. An exterior environment recognition device obtains an image in a detection area, generates a block group by grouping, based on a first relative relationship between blocks, multiple blocks in an area extending from a plane corresponding to a road surface to a predetermined height in the obtained image, divides the block group into two in a horizontal direction of the image, and determines, based on a second relative relationship between two divided block groups, whether the block group is a first person candidate which is a candidate of a person. | 07-11-2013 |
20150092989 | VEHICLE EXTERNAL ENVIRONMENT RECOGNITION DEVICE - A vehicle external environment recognition device includes a three-dimensional position deriving module that derives three-dimensional positions in real space of subject parts in images that are obtained by imaging a detection area, an object identifying module that groups the subject parts of which differences in the three-dimensional position are within a predetermined range to identify an object, an edge intensity deriving module that horizontally divides an area containing the object to set divided areas, and derives an edge average that is an average value of edge intensities based on a luminance value of each pixel within each of the divided areas; and a floating matter identifying module that compares the edge average with a predetermined threshold, and identifies the object to be likely floating matters when the edge average is less than the threshold. | 04-02-2015 |

20130336387 | VIDEO ENCODING DEVICE, VIDEO ENCODING METHOD AND VIDEO ENCODING PROGRAM - A video encoding device, which uses intra encoding and inter encoding with motion compensation with respect to an input video signal, includes a determination unit which determines whether the input video signal to be encoded corresponds to a stationary region, a region having minute motion, or a region having normal motion, a first encoding unit which performs inter encoding of a motion vector (0, 0) with respect to a region determined as a stationary region by the determination unit, a second encoding unit which performs motion search and inter encoding in a limited search range with respect to a region determined as a region having minute motion by the determination unit, and a third encoding unit which performs motion search and inter encoding in a normal search range with respect to a region determined as a region having normal motion by the determination unit. | 12-19-2013 |
20130343453 | QUANTIZATION CONTROL APPARATUS AND METHOD, AND QUANTIZATION CONTROL PROGRAM - A quantization control apparatus provided in a video encoding apparatus which utilizes intra slices. The quantization control apparatus includes a similarity computation device that computes similarity between an intra slice region of an encoding target picture and an intra slice region of each of previously-encoded pictures, where the similarity is an index determined such that the closer the images of the two different intra slices, the higher the similarity; a picture selection device that selects a picture having the highest similarity from among the previously-encoded pictures, based on the similarity computed by the similarity computation device; and a quantization step determination device that determines a quantization step used for encoding the encoding target picture, based on encoding information for the picture selected by the picture selection device. | 12-26-2013 |
20140341279 | FRAME RATE CONTROL METHOD, FRAME RATE CONTROL APPARATUS, AND FRAME RATE CONTROL PROGRAM - An object is to suppress an instantaneous increase in the computational complexity of an encoder and an information amount of an encoding result without increasing a delay even when input timing of input video is not constant and fluctuates. A frame rate control method for adjusting a frame rate of input video to a frame rate at which an encoder is able to perform encoding includes: a step of determining whether the number of pictures input in the past within a predetermined time from a time when a determination target picture of dropping is input exceeds a predetermined threshold value; and a step of discarding the determination target picture if the number of pictures exceeds the threshold value and designating the determination target picture as an encoding target if the number of pictures does not exceed the threshold value. | 11-20-2014 |
