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.

Data input apparatus having multiple lens unit

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.

Three-dimensional measuring device and three-dimensional measuring method

When a scanning start position set signal is input in an area image sensor, the content is transferred to a vertical scanning circuit, and the scan start position is set. Image of a desired row is read by horizontal scanning. Then, one shift signal for vertical scanning is input, the position of scanning is shifted by one row, and horizontal scanning is performed. Thus image of the next row is read. By repeating this operation, a desired strip-shaped image is read. The shape of the object is determined and when a portion is determined to have complicated shape, the image data is input by means of a lens having long focal length, and image data of other portions are input by means of a lens having short focal length. By putting together a plurality of input image data, image data as a whole is generated.
