    • A method for locating points on a surface, in which the surface is irradiated selectively with an irradiating volume which has a varying intensity that defines a first pattern. After irradiating the surface with the first pattern, the surface is irradiated similarly with volume(s) having varying intensity(ies) defining a second (or more) pattern(s). Both (or all) of these patterns are applied to a point to be located on the surface. The radiation impinging on the surface is recorded by a camera which forms images of these patterns. The images are scanned to find the intensities of the point in the two (or more) patterns. The location of the point on the surface is dependent on a predetermined ratio or difference of the intensities of the point in the two (or more) patterns. The patterns may be linear, sinusoidal, smooth, non-smooth and/or two dimensional functions ultimately producing a single valued ratio or difference result.
    • 用于定位表面上的点的方法,其中表面被选择性地照射具有限定第一图案的变化强度的照射体积。 在用第一图案照射表面之后,类似于具有限定第二(或更多)图案的强度变化的体积的表面被照射。 这些图案的(或全部)都被应用于要位于表面上的点。 通过形成这些图案的图像的照相机记录入射在表面上的辐射。 扫描图像以查找两个(或多个)图案中的点的强度。 表面上的点的位置取决于两个(或多个)图案中点的强度的预定比率或差。 这些图案可以是线性的,正弦的,平滑的,非平滑的和/或二维的功能,最终产生单值或差分结果。

    • A navigational plotter in which a geographical map or chart has marked thereon lines of position corresponding to the Omega or Loran navigation system aids, for example. The intersections of the lines of position with a base line on the chart are recorded in coded form on a separate strip of the chart. The coded signals on the chart strip are read out by the plotter, so that the position of the marker or indicator of the plotter may be read out directly in terms of lines of position corresponding to Omega or Loran systems. The marker or indicator of the plotter may also be positioned directly from information obtained in terms of Omega or Loran lines of position.
    • 例如,导航绘图仪,其中地理图或图表上标有对应于欧米茄或罗兰导航系统的位置线。 位置线与图表上的基线的交点以编码形式记录在图表的单独条上。 图表条上的编码信号由绘图仪读出,从而可以根据与欧米茄或罗兰系统对应的位置线直接读取绘图仪的标记或指示器的位置。 绘图仪的标记或指示器也可以直接从以Omega或Loran位置线获得的信息定位。

    • An arrangement for obtaining three-dimensional position data on surfaces defining a room, and objects enclosed by that room. The room is scanned with a master and slave sensors to determine the three-dimensional profiles of surfaces that are visible to the sensors. A pattern is then projected by the master sensor onto a known surface, and slave sensors spaced from the master sensor search for that pattern. The position of the pattern is determined angularly by each slave sensor, and the projection of the pattern is thereafter discontinued. Each salve sensor then measures the distance to the known surface at that angle with respect to its own coordinate system. This is repeated three times so that three such patterns are located. The position data from all of the sensors are transformed into a single common coordinate system, based upon sensor locations determined by the measurement of the three patterns.
    • 用于在限定房间的表面上获得三维位置数据的装置以及由该房间包围的物体。 用主和从传感器扫描房间,以确定传感器可见的表面的三维轮廓。 然后,主传感器将图案投影到已知表面上,与主传感器间隔的从属传感器搜索该图案。 图案的位置由每个从属传感器成角度地确定,然后停止图案的投影。 然后每个萨尔夫传感器相对于其自己的坐标系以该角度测量到已知表面的距离。 重复三次,以便找到三个这样的图案。 基于通过三种模式的测量确定的传感器位置,来自所有传感器的位置数据被转换成单个公共坐标系。

    • An arrangement for removing excess material from an object surface, to provide a desired finished surface. Holes are drilled into the object so that the bottoms of the holes lie on the desired finished surface. The holes have a shape so that the observed hole diameter at the prevailing surface of the object is dependent on the hole depth and thereby dependent on the amount of material remaining to be removed between the prevailing surface and the desired finished surface. The prevailing surface is continuously observed and measured, and the depths of material to be removed in a sequence of steps is calculated dependent on the measurements of the prevailing surface and the coordinates of the desired finished surface. As a result of the calculations, the depth of material removed during each step is controlled, so that upon carrying out a sequence of such steps, the surface exposed on the object after the last step has been carried out, coincides with the desired finished surface. The accuracy of the material removal equipment may be substantially less than the accuracy of the finished surface. Grooves instead of circular holes are cut when the radius of curvature of both the prevailing and desired surfaces becomes sufficiently small, so as to provide sufficient definition of the desired surface. With the grooves, the observed parameter is groove width rather than hole diameter.
    • 用于从物体表面去除多余材料的装置,以提供所需的成品表面。 将孔钻入物体中,使得孔的底部位于所需的成品表面上。 这些孔具有这样的形状,使得在物体的主要表面处观察到的孔直径取决于孔深度,并且因此取决于在主要表面和期望的成品表面之间剩余的待除去的材料的量。 连续地观察和测量主要表面,并且根据主要表面的测量和所需成品表面的坐标来计算要按顺序排列的材料的深度。 作为计算的结果,控制在每个步骤期间去除的材料的深度,使得在执行一系列这样的步骤时,在最后一步之后暴露在物体上的表面已经被执行,与期望的成品表面重合 。 材料去除设备的精度可以显着小于成品表面的精度。 当主流和期望的表面的曲率半径变得足够小时,切割代替圆形孔的凹槽,以便提供所需表面的足够的定义。 对于凹槽,观察到的参数是凹槽宽度而不是孔直径。
