    • A distance distribution measuring method includes the steps of disposing an image pickup on the optic axis of a projection optical system, forming on the image pickup the images of objects existing in multiple directions through the projection optical system, progressively varying the spacing in the direction of the optic axis between the projection optical system and the image pickup, extracting substantially in-focus one of the object images on the image pickup for each amount of spacing along with the step of varying the spacing, and finding the distance to an object corresponding to each object image extracted at the step of extracting, on the basis of the amount of spacing when the object image is extracted, thereby obtaining the distances to the objects existing in the multiple directions and measuring the distance distribution.
    • 距离分布测量方法包括以下步骤:在投影光学系统的光轴上设置图像拾取器,在图像拾取器上形成通过投影光学系统存在于多个方向上的物体的图像,逐渐改变沿着 投影光学系统和图像拾取器之间的光轴,随着每个间隔距离的图像拾取器基本上对焦中的一个物体图像以及改变间隔的步骤,并且找到与对应于对象的对象的距离 在提取对象图像时的间隔量的提取步骤中提取每个对象图像,从而获得与存在于多个方向上的对象的距离并测量距离分布。

    • A visual field searching device is arranged to divide the visual field to be searched into a plurality of intermediate fields each of which is larger than a constituent unit field; to select, for each of the intermediate fields, a typical or representative object distance data from among object distance data obtained for individual constituent unit fields included in each intermediate field; further, for each intermediate field, to discriminate whether the representative distance data thus selected is in a predetermined relation to other object distance data; and after that, to perform a signal processing operation to obtain necessary information by processing only the number of data representing the intermediate fields instead of processing all the data for all the constituent unit fields.
    • 视野搜索装置被布置成将要搜索的视野分成多个中间场,每个中间场大于构成单位场; 为每个中间场选择从每个中间场中包括的各个构成单位字段获得的对象距离数据中的典型或代表性对象距离数据; 此外,对于每个中间字段,判别由此选择的代表性距离数据是否与其他对象距离数据成预定关系; 之后,通过仅处理表示中间字段的数据的数量来执行信号处理操作以获得必要的信息,而不是处理所有构成单位字段的全部数据。

    • An object information processing apparatus includes a focussing unit for focussing light information from an object point; a light transmission unit for transmitting the light information from the object point to the focussing unit via first and second optical passages; and mask units provided respectively in the first and second optical passages in the light transmission unit and formed respectively with predetermined patternings which are in negative and positive relation to each other. By virture of the mask units, the light information from the object point is blocked into a plurality of distance informations from which distance patterns are obtained. The apparatus can recognize an object in three dimensions using the distance patterns. Since the apparatus has no mechanically movable parts and the light passed through the first and second optical passages is focussed side by side on a photosensor, a high resolution is obtained and mutual references of corresponding points of the object are readily obtained.
    • 对象信息处理设备包括:聚焦单元,用于聚焦来自物点的光信息; 光传输单元,用于经由第一和第二光学通道将光信息从物点传送到聚焦单元; 以及分别设置在光传输单元中的第一和第二光学通道中的掩模单元,并分别形成彼此为负的和正的关系的预定图案。 通过掩模单元的病毒,来自对象点的光信息被阻塞成多个距离信息,从该距离信息获得距离图案。 该装置可以使用距离图案识别三维的对象。 由于该装置没有机械可移动部件,并且通过第一和第二光学通道的光被并排聚焦在光传感器上,所以获得高分辨率,并且容易地获得对象的对应点的相互参考。
