    • A waterproof camera has a waterproofing camera case (front and rear cases) and a lens barrel secured within the camera case. Within the lens barrel, there is formed a lens-containing space communicating to a front opening thereof. A group of lenses for wide-angle imaging are arranged in the space. A front lens of the lenses is placed to cover the opening, so that the front lens serves in common as a sealing member. An annular protrusion of tip of the lens barrel is caulked inside by thermal welding. An O-ring is inserted between an outer cylindrical surface of the front lens and an inner wall cylindrical surface of the lens barrel. Another O-ring is inserted between an outer cylindrical surface of tip of the lens barrel and an inner cylindrical surface of tip of the front case.
    • 防水相机具有防水相机外壳(前后外壳)和固定在相机外壳内的镜筒。 在透镜镜筒内,形成有与前开口连通的透镜容纳空间。 一组用于广角成像的透镜被布置在该空间中。 透镜的前透镜被放置以覆盖开口,使得前透镜作为密封构件共同使用。 透镜筒顶端的环形突起通过热焊接在内部。 O形环插入在前透镜的外圆柱形表面和透镜镜筒的内壁圆柱形表面之间。 另一个O形环插入在镜筒顶端的外圆柱形表面和前壳前端的内圆柱形表面之间。

    • A single video camera is installed on a vehicle body. Two still pictures of an obstacle are obtained at different vehicle traveling positions. A picture memory stores the obtained still pictures. A feature point extracting section extracts at least one feature point from the data of the stored still pictures. A three-dimensional coordinate data calculating section calculates the distance from the vehicle body to the feature point and the height of the feature point based on the positional data of the feature point on the screen and the vehicle traveling distance data. A stereoscopic picture forming section forms a stereoscopic picture image of a detected obstacle based on three-dimensional coordinate data of the feature points. A monitor displays a plan view or a side view showing the relationship between the vehicle body and the obstacle, thereby allowing a driver to directly grasp the distance of the obstacle. When the obstacle is located within a predetermined distance from the vehicle body, the driver is cautioned against a predictable collision by the alarm sound or related image.
    • 单个摄像机安装在车体上。 在不同的车辆行驶位置获得障碍物的两个静止图像。 图像存储器存储所获得的静止图像。 特征点提取部从所存储的静止图像的数据中提取至少一个特征点。 三维坐标数据计算部根据屏幕上的特征点的位置数据和车辆行驶距离数据,计算从车身到特征点的距离和特征点的高度。 立体图像形成部基于特征点的三维坐标数据形成检测到的障碍物的立体图像。 监视器显示示出车身与障碍物之间的关系的平面图或侧视图,从而允许驾驶员直接掌握障碍物的距离。 当障碍物位于距车体预定距离内时,驾驶员被警告声或相关图像警告为可预测的碰撞。
