    • 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.
    • 提供一种能够即使当物体移动时能够高精度地测量物体的位置的装置。 车辆周边监视装置(10)计算在指定间隔(&Dgr; T)之间分开的两次之间的对象区域的大小的变化率(Rate(t))。 指定的间隔(&Dgr; T)是定义的时间间隔,使得图像中的对象的形状和姿势类似于或相互匹配,使得可以识别对象是相同的。 基于指定间隔(&Dgr; T)期间对象区域的大小的变化幅度(Rate(t)),可以测量从车辆(1)到物体或高位置的距离 即使对象正在移动,也能确定精度。

    • A damper mechanism 4 has an input rotary body 2, a hub flange 6, a splined hub 3, a third friction washer 60, a bushing 70, and an output plate 90. The third friction washer 60 is non-rotatably mounted on the hub flange 6 with respect to the hub flange 6, and has a friction member that contacts the input rotary body 2 in the axial direction. The bushing 70 is axially disposed between the hub flange 6 and the third friction washer 60, and is mounted on the hub flange 6 and the third friction washer 60 to be incapable of rotation with respect to the third friction washer 60. The output plate 90 is disposed between the third friction washer 60 and the bushing 70 in the axial direction, and is supported by the splined hub 3 to be capable of rotating integrally with the splined hub 3.

    • A vehicle environment monitoring apparatus capable of extracting an image of a monitored object in an environment around a vehicle by separating the same from the background image with a simple configuration having a single camera mounted on the vehicle is provided. The apparatus includes a first image portion extracting processing unit to extract first image portions (A1, A2) considered to be the head of a pedestrian from a currently picked up image and a previously picked up image by an infrared camera, a mask area setting processing unit to set mask areas (M1(0,0), M1(1,0), . . . , M1(5,8)) around the first image portion (A1) in the currently picked up image, and an object extracting processing unit to carry out pattern matching for the previously picked up image by a comparison pattern obtained through affine transformation of each mask area at a change rate (Rate) between the first image portions (A1, A2), and to set an area (Ar1) including the first image portion (A2) and a second image portion (M2(1,3), M2(2,3), . . . , M2(3,6)) where a displacement amount between the position (black point) corresponding to the centroid of the mask area and the matching position is smaller than a predetermined threshold value to be an image area of the monitored object.
