Abstract: Frame data of tomographic planes that are parallel in the scan direction and between an X-ray tube and an X-ray detecting unit is generated based on detected frame data. The generation of frame data is based on the fan-shaped spreading of an X-ray beam and the differences in position in a height direction between the tomographic planes from a detection surface. Tomographic images are respectively generated from the frame data of the tomographic planes based on laminography technique. Edge information based on the changes in pixel values in each tomographic image is calculated for each pixel. A three-dimensional distribution of the edge information is generated and the edge information is searched in a direction passing through the tomographic planes and pixels indicating a maximum value in the edge information are detected. Only pixels in the tomographic images that positionally correspond to detected pixels are combined into a single composite image.

Abstract: A vehicle lamp control apparatus includes a receiver, a storage, a correction section, and an adjustment instruction section. The receiver receives output values of an acceleration sensor. The storage stores information indicating an ideal positional relationship between sensor-side axes and vehicle-side axes. The correction section plots the output values, obtained during running of a vehicle, on coordinates in which acceleration in a vehicle longitudinal direction is set to a first axis and acceleration in a vehicle lateral/vertical direction is set to a second axis, derives a straight line from plotted points, calculates displacements of the sensor-side and vehicle-side axes from the ideal positional relationship, using an inclination of the straight line, and corrects the information. The adjustment instruction section derives a tilt angle of the vehicle from current acceleration using the corrected information, and generates a control signal to instruct adjustment of an optical axis of a vehicle lamp.

Abstract: A frequency of an unnecessary operation of automatic braking due to a reflected wave from a guard rail is decreased. When a collision avoidance control unit determines that an obstacle detected by a radar sensor and an own vehicle are highly likely to collide with each other, the collision avoidance control unit reads a state signal output by a parking support control unit, and determines whether or not the state signal indicates a specific state, which is a state where parallel parking support is being carried out or a state where exit support is being carried out. When the state signal indicates the specific state, the collision avoidance control unit inhibits the automatic braking.

Abstract: A vehicle-lamp control device includes a control unit that adjusts an optical axis with respect to a change in a total angle that includes a road surface angle and a vehicle attitude angle while the vehicle is at rest, and maintains the optical axis with respect to a change in the total angle while the vehicle is traveling. The control unit fixes the optical axis angle when a fault state of the control device is detected. Upon the control device having recovered from a fault state, the control unit generates an adjustment signal either upon estimating a current vehicle attitude angle on the basis of an output value from the tilt sensor obtained while the vehicle is traveling, or upon receiving a signal indicating a current vehicle attitude angle from an external device.
