摘要： A driving assistance device includes a camera, a moving object detector, a candidate reflection region detector, a predetermined position brightness detector and a cause determiner. The moving object detector and the candidate reflection region detector set a detection region for detecting, from image data captured by the camera, an existence of an adjacent vehicle in an adjacent lane. The predetermined position brightness detector detects a candidate light projecting object which projects light with brightness equal to or higher than a predetermined threshold value. The cause determiner determines whether or not there exists a candidate light projecting object which indicates the existence of the adjacent vehicle in the detection region.

摘要： A three-dimensional object detection device basically includes a three-dimensional object detection unit, a natural object assessment unit and a control unit. The three-dimensional object detection unit detects three-dimensional objects based on image information of a rear of a vehicle from a camera. The natural object assessment unit assesses that a detected three-dimensional object is a natural object, such as a plant or snow, based on an irregularity evaluation value calculated based on a first pixel number of first pixels representing a first predetermined differential in the differential image containing the detected three-dimensional object and a second pixel number of second pixels corresponding to the three-dimensional object and representing a second predetermined differential greater than the first predetermined differential.

摘要： A moving-body-detecting device is provided with an image capture unit, an image conversion unit, a three-dimensional-object-detecting unit, a turn detecting unit, and a control unit. The image capture unit captures images of the rear side of a vehicle. The image conversion unit performs viewpoint conversion of the captured images into bird's-eye view images. The three-dimensional-object-detecting unit generates differential waveform information based on a differential image of bird's-eye view images taken as different points in time, and detects three-dimensional objects based on the differential waveform information. The control unit suppresses detection of the three-dimensional object based on the differential waveform information, in cases in which turning of the vehicle has been detected as compared with cases in which the vehicle is not turning.

摘要： A solid object detection device detects solid objects in the periphery of a vehicle. A camera captures images including detection regions set in adjacent traffic lanes to the rear of the vehicle. A solid object assessment unit assesses whether or not a solid object is present in the detection regions. A lateral position detection unit detects a distance between the vehicle position and a dividing line that divides traffic lanes. A region setting unit enlarges the detection region on the side of the dividing line by a greater amount correspondingly with respect to an increase in the distance to the dividing line. A traffic lane change detection unit detects a traffic lane change made by the vehicle. Upon detecting a traffic lane change by the vehicle, a smaller enlarged amount is used when enlarging the size of the predetermined region outward in the vehicle-width direction.
