Abstract:
In an in-vehicle target detecting device, a captured image which is an image capturing an area ahead of the own vehicle is acquired at a predetermined measurement cycle. Radio waves are transmitted and received. Positional information indicating at least an orientation and a distance of at least one target candidate in relation to the own vehicle is acquired. The target candidate reflects radio waves. Image recognition is performed to detect a detection object by searching a predetermined image search area in the captured image. At least an image detection position of the detection object in the captured image is stored. The image search area is set, based on an image-plane measurement position corresponding to a measurement position in the captured image. The measurement position is a position in three-dimensional space of the target candidate indicated by the positional information acquired at a timing at which the captured image is acquired.
Abstract:
An inattentive state determination apparatus being placed in a vehicle includes an image taking section, an orientation detection section, a determination section, a warning section, a shape detection section, and a setting section. The image taking section successively takes images of a face of a determination target. Based on the images, the orientation detection section and the shape detection section detect a determination target orientation and a hand shape, respectively. The determination section determines whether the determination target is in an inattentive state based on the determination target orientation by determining an inattentive state determination condition. The warning section notifies the inattentive state by outputting an audio warning corresponding to a parameter of the audio warning. The setting section sets at least one of the inattentive state determination condition and the parameter of the audio warning based on the hand shape and the determination target orientation.
Abstract:
A current sensor includes: a magneto electric conversion element; and a magnetic field concentrating core applying a magnetic field caused by a measurement object current to the magneto electric conversion element. A planar shape of the magnetic field concentrating core perpendicular to a current flowing direction is a ring shape with a gap. The magneto electric conversion element is arranged in the gap. A part of a conductor for flowing the current is surrounded by the magnetic field concentrating core. The magnetic field concentrating core includes two first magnetic members and at least one second magnetic member, which are stacked alternately in the current flowing direction. Parts of the two first magnetic members adjacent to each other via the one second magnetic member are opposed to each other through a clearance or an insulator.
