摘要： Provided is an apparatus capable of, even when an object is moving, measuring the position of the object at a high accuracy. According to a vehicle periphery monitoring apparatus (10), an enlargement factor relevant to when the degree of correlation between an enlarged local region (EB(γi)) obtained by enlarging a local region (B(k−1)) at a previous time (k−1) and a local region (B(k)) at a time (k) later than the previous time (k−1) becomes the maximum is calculated as a change rate (Rate(k)) of the size of the local region (B(k)). Based on the change rage (Rate(k)), it is possible to measure the distance (Z(k)) from a vehicle (1) to the object or the position (P(k)) at a high accuracy even when the object is moving.

摘要： An imaging means mounted on a vehicle performs imaging resulting in grayscale images having brightness values corresponding to object temperature, and objects around the vehicle are detected from said images. On the basis of said grayscale images, display images to be displayed on a display device mounted on the vehicle are generated and displayed on the display device. The display images are generated by lowering the brightness of areas not corresponding to the objects detected in the grayscale images. The display device is positioned in the vehicle width direction at no more than a prescribed distance away from an imaginary line passing through the center of rotation of the vehicle steering wheel and extending in the longitudinal direction of the vehicle. Accordingly, because display images are generated in which only the objects are spotlighted, the driver can quickly comprehend the objects present when using a display device.

摘要： A vehicle periphery monitoring device is operable to report a high contact possibility between a vehicle and an object at an appropriate time or frequency according to the type of the object. When the object is determined to be a human being and the position of the object in real space is contained in a first contact determination area, a high contact possibility between the vehicle and the object is reported. On the other hand, when the object is determined to be a quadruped animal and the real spatial position of the object is contained in a second contact determination area, the corresponding report is made. The second contact determination area has an overlapped area that overlaps with the first contact determination area, and an overflowed area that has at least a part thereof overflowing from the first contact determination area.

摘要： Provided is an apparatus capable of, even when an object is moving, measuring the position of the object at a high accuracy. A vehicle periphery monitoring apparatus (10) calculates the change rate (Rate(t)) of the size of an object region between two times separated by a specified interval (ΔT). The specified interval (ΔT) is a time interval defined so that the shapes and postures of an object in images resemble or match each other to such an extent that it is possible to identify that the object is identical. Based on the change rage (Rate(t)) of the size of the object region during the specified interval (ΔT), it is possible to measure the distance from a vehicle (1) to the object or the position at a high accuracy even when the object is moving.
