Abstract: A data input apparatus having a multiple lens unit comprising an image input device for inputting two-dimensional images of a photographic subject from a plurality of mutually different viewpoint positions, a display device, and a display controller for displaying on the display device an overlay image formed by mutually superimposing a plurality of input two-dimensional images.

Abstract: This invention is related to a three-dimensional measuring device for measuring three-dimensional positions of an objects. The three-dimensional measuring device comprises an optical projection system and an optical reception system. In a preliminary measurement prior to an actual measurement, the optical projection system projects slit light beam on the object with varying projection angle with in a narrow range, and the optical reception system receives the slit light beam reflected by the object and generates image signals corresponding to an amount of the received light synchronously with variation of the projection angle. Measurement conditions including intensity of the light beam and the projection angle for the actual measurement are set in accordance with the image signals of the actual measurement. Under the measurement conditions, the actual measurement is executed by projection the light beam on the object with varying the projection angle within a wide range.

Abstract: In a three dimensional measurement system, a three dimensional pickup apparatus picks up an object repeatedly to generate image information including a shape of the object, and an information processor receives image frame signals and digital signals from the pickup apparatus to process the image information. Image information is sent as image frame signals through a first output terminal, and digital signals are sent through a second output terminal in correspondence to output of the image information through the first output terminal. In the information processor, an input controller receives the digital signals from the first output terminal and receives the image frame signals suitable for transmission of moving images in correspondence to the received digital signals from the second output terminal. For example, the pickup conditions for a next period are set based on the pickup information obtained in a current period.

Abstract: A distance measuring apparatus of an apparatus having a moving mechanism includes: a speed detector; and a mechanism responsive to a moving speed signal supplied from the speed detector which varies a focus lens position and a focal length of a light receiving optical system, a scanning range of a light projecting optical system, a base length, a position where light axes of a pair of light receiving optical systems or light axes of the light receiving and light projecting optical systems cross with each other, or responsive to a moving direction signal supplied from a moving direction detecting means of the apparatus having the moving mechanism which changes a measurement direction of a field of view. Thus, optimal measurement accuracy and a field of view to be measured can always be provided even though the moving speed or the moving direction of the apparatus having the moving mechanism is varied.
