Abstract: An image processing apparatus includes an input interface configured to acquire images captured by a camera and a controller configured to detect an edge corresponding to at least one of two or more parallel, straight lines included in the subject of the camera from each of a plurality of frames acquired by the input interface, to select a frame for use by evaluating the detected edge, and to calculate calibration data for the camera on the basis of an approximate straight line corresponding to edge pixels obtained from a plurality of selected frames.

Abstract: A calculation device comprises a controller configured to extract, from a captured image of a subject, a plurality of lines corresponding to straight lines parallel to each other in the subject, and to calculate first calibration data so that mapping lines obtained when the extracted plurality of lines are mapped to a three-dimensional coordinate space are parallel to each other.

Abstract: Provided is an image processing device including: an input interface, which is configured to acquire a first captured image and a second captured image that are captured by a plurality of imaging units and; and a controller, which is configured to calculate parallax by performing a one-dimensional matching based on pixel values of the first captured image and pixel values of the second captured image, extracts one or more first feature points from a region in the first captured image that includes continuous pixels having a difference in parallax which is within a predetermined range, extract one or more second feature points corresponding respectively to the first feature points by performing a two-dimensional matching with the first feature points, and calibrate the imaging unit based on positions of the first feature points and positions of the second feature points.

Abstract: A solid oxide fuel cell includes a solid electrolyte layer, a fuel electrode layer that is disposed on one surface of the solid electrolyte layer, an oxygen electrode layer that is disposed on the other surface of the solid electrolyte layer, and an intermediate layer that is disposed between the solid electrolyte layer and the oxygen electrode layer and that includes ceria-based particles containing rare earth elements other than cerium and ceramic particles consisting of oxide of a metallic element different from that of the ceria-based particles. The ceramic particles having a smaller average particle diameter than that of the ceria-based particles exist in grain boundaries of the ceria-based particles of the intermediate layer.

Abstract: A segmented-in-series solid oxide fuel cell stack of the invention comprises: an electrically-insulating porous support body having a gas passage therein; and a plurality of fuel cells arranged side by side on a surface of the support body. Each fuel cell have a first inner electrode layer; a current collector and a second inner electrode layer arranged side by side on the first inner electrode layer; and a solid electrolyte layer and an outer electrode layer sequentially laminated on the second inner electrode layer, and have a multilayer structure in which the solid electrolyte layer is extended and connected to the current collector through an intermediate layer. These fuel cells are connected in series. The current collector and the second inner electrode layer are arranged with a predetermined clearance therebetween on the first inner electrode layer. A fuel cell of the invention is formed by storing these segmented-in-series solid oxide fuel cell stacks in a storage container.
