    摘要: In a photogrammetric analytical measurement system, a survey map is produced on the basis of two respective photographed pictures obtained at two different photographing positions. Each of the pictures includes an object image to be recorded on the survey map, and a standard measurement scale image for producing an accurately scaled object image. Data for producing the survey map is approximately calculated on the basis of two-dimensional position data inputted to the computer by designating the scale image and the object image on the pictures with a cursor, by an operator's manipulation of a mouse. When the results of the approximate calculations are erroneous, it is indicated that the inputting of the two-dimensional position data, by designation of the object image with the cursor, should be repeated.

    摘要: A standard scale used in a photogrammetric measurement system has a polygonal plate having three apexes which are arranged to define a reference plane, where each of the apexes defines a reference point. Another standard scale has a light-guide plate member which has three light-emitting spots for defining reference points. Yet another standard scale has a frame member, and reference-point-forming elements, for defining reference points, arranged on the frame to define a reference plane. A marker used in a photogrammetric measurement system for defining a standard scale has a light-guide plate having a light emitting spot for defining a reference point. Another marker has a polygonal-pyramidal-shaped optical assembly formed from light-guide plates, including a core layer containing fluorescent substances, such that an apex of the optical assembly is defined by an emission of fluorescent radiation therefrom.

    摘要: An optical member inspecting apparatus comprises an illuminating unit for illuminating a target lens to be inspected and a photographing unit to detect the light transmitted through the target lens. The illumination unit has a circular diffuser plate on which a semi-circular light intercepting plate is attached. The diffuser plate can rotate about a rotation axis. The target lens is supported by an X-Y stage that moves the target lens in a plane perpendicular to the rotation axis. An image processing unit detects brightness distributions at different rotational positions of the light intercepting plate to calculate a brightness difference which represents a deviation of the optical axis of the target lens from the rotation axis. The image processing unit controls the X-Y stage based on the brightness difference so as to correct the deviation.

    摘要: An optical element inspecting apparatus for inspecting optical elements for defects. The optical element inspecting apparatus includes an illuminating unit, an image capturing unit, two polarizers, a rotation device, a controller, and a means for composing a plurality of image data captured by the image capturing unit. The optical element to be inspected is placed between the polarizers and is illuminated by the illuminating unit. The light that passes through the polarizers and the optical element is captured by the image capturing unit and stored in memory. The controller controls the rotation device such that the polarizers are rotated by a predetermined amount and a subsequent image data is captured. In this way, a number of image data are captured and all image data are composed to make a composite image data. The optical element is examined to detect flaws therein by using the composite image data.
