Abstract: An image processing apparatus includes an image acquisition unit and a determination unit. The image acquisition unit uses a camera to acquire a first image representing an area in a first relative position and a second image representing an area in a second relative position closer to the moving direction of the vehicle than the first relative position. The determination unit compares the first image with the second image acquired earlier than the first image and representing an area overlapping the first image for luminance and/or the intensity of a predetermined color component to determine whether there exists a specific area higher in luminance than the surroundings or lower in luminance than the surroundings in the first image.

Abstract: In a display processing device, an acquisition section acquires a captured image of surroundings of the vehicle from at least one imaging device installed in a vehicle. A first generation section generates a first converted image that is an image as seen from a first viewpoint in the vehicle, based on the captured image at a latest imaging time point. A calculation section calculates displacement of the vehicle. A second generation section generates a second converted image that is an image as seen from the first viewpoint at the latest imaging time point and is an image of an area including under the vehicle, based on the captured image captured earlier than the latest imaging time point and the displacement. The display processing section causes a display device visible to an occupant of the vehicle to display a display image obtained by compositing the first and second converted images.

Abstract: A parking space detection apparatus detects a parking space of an own vehicle and includes: a vehicle determination section that determines whether an other vehicle is present on at least one of two sides of a parking space, based on search information acquired from an in-vehicle search section that searches for the parking space; a width calculation section that, it is determined that the other vehicle is present on at least one of the two sides of the parking space, calculate a width of the parking space on an entrance side and a width of the parking space on an inner side based on the search information; and a parking determination section that determines whether the own vehicle is able to park in the parking space based on the widths of the parking space on the entrance side and on the inner side and size of the own vehicle.

Abstract: In an obstacle detection apparatus, the captured image of a vicinity of a vehicle from an imaging apparatus is acquired. A three-dimensional estimation image showing a three-dimensional position of a feature point in the captured image is generated, and a three-dimensional position of an object is estimated. An attribute image in which an object in the captured image is classified into one or more classes that include at least a road-surface class is generated. The three-dimensional estimation image and the attribute image are fused, the feature points and the classes are associated, and road-surface points associated with the road-surface class are extracted. Based on the road-surface points, a road-surface height in the vicinity of the vehicle is estimated. Based on the estimated road-surface height, the three-dimensional position of the object is corrected. Based on the three-dimensional position of the object, an obstacle in the vicinity of the vehicle is detected.

Abstract: A mounting angle detection device converts, into a bird's-eye view image, an image captured of the ground on which a target marking having two straight line parts parallel to each other and equal in width is marked, and searches for a mounting angle at which the two straight line parts in the bird's-eye view image are parallel to each other and equal in width. Even with a vehicle including an in-vehicle camera on the front or back, the mounting angle detection device detects an actual mounting angle of the camera and calibrates the mounting angle of the camera. The mounting angle detection device detects the mounting angle using, as the target marking, even a parking space that lacks a transverse line crossing the two straight line parts parallel to each other and equal in width, and calibrates the mounting angle to a correct mounting angle of the camera.

Abstract: An image processing unit generates a corrected bird's-eye-view image that is a captured bird's-eye-view image and that is a bird's-eye-view image from which irradiation light present in the captured image has been removed. The corrected bird's-eye-view image is generated as a bird's-eye-view image representing a difference between the captured bird's-eye-view image and a difference image that is an image representing a change in a pixel value of the captured bird's-eye-view image. The image processing unit generates a corrected history image that is a bird's-eye-view image obtained by combining the corrected bird's-eye-view images while shifting positions of the corrected bird's-eye-view images on the basis of a movement amount of the own vehicle. The image processing unit generates a corrected display image that is a bird's-eye-view image obtained by combining the corrected history image and the latest captured bird's-eye-view image, and makes a display unit display the corrected display image.

Abstract: An image processing apparatus includes: an image obtaining device; an image dividing device that divides the image through a fine structure retrieving filter and a basic structure retrieving filter into a detail signal component and a basic signal component, the detail signal component including an edge component, a texture component, and a noise component, and the basic signal component being other than the detail signal component; an image correcting device that retrieves a focused picture cell, determines whether the focused picture cell represents the noise, corrects the detail signal component to reduce the noise component in the focused picture cell when the focused picture cell represents the noise; and an image synthesizing device that synthesizes a basic structure image provided by the basic signal component and a corrected fine structure image provided by the corrected detail signal component.
