An object is to provide a three-dimensional data input apparatus that enables data currently required by the user to be easily extracted from the stored past three-dimensional data, shooting position data or shooting direction data. When the user provides the three-dimensional measuring device 1 with a measurement instruction, the portions operate through control by the central processing portion 17 to obtain the three-dimensional data SS and the two-dimensional image data SN of the object Q. The group of the three-dimensional data SS, the two-dimensional image data SN, the position data SP and the attitude data SA that are in the one-to-one correspondence with one another as described above are stored in the storage portion 18 every time the three-dimensional data of the object Q is measured. In a case where a fixed point observation of the object is repetitively performed by use of the three-dimensional measuring device 1, by extracting from the storage portion 18 three-dimensional data SSK and two-dimensional image data SNK obtained in the past and comparing them with the present three-dimensional data SSG and two-dimensional image data SNG, the change in the configuration of the object during that period can be found.

A system comprises a two-dimensional photographing device and a three-dimensional measuring device that is removably attached to the two-dimensional photographing device. The two-dimensional photographing device and the three-dimensional measuring device can communicate with each other. Information indicating an operating condition of one of the devices is transmitted to the other device, which receives the information and sets own operating condition in accordance with the received information for photographing or measuring.

A measuring section for measuring a three-dimensional shape of an object by scanning the object, and a display section for displaying information about an area where the scanning has been already completed in accordance with the progress of the scanning are provided. Thus, an image for clarifying the area where the scanning has been already completed and an area where the scanning has not been completed yet is displayed, and the progressing status of the scanning can be grasped accurately by a user.

Method and apparatus for measuring three dimensional information of a target placed in an interior space of a rotator type mirror by using the rotator type mirror in combination with an imaging apparatus disposed with its light receiving axis aligned with a center axis of the rotator type mirror. The invention includes projecting reference light toward the rotator type mirror from a position on the center axis, and scanning the target with mirror reflected reference light that is produced by reflecting the reference light on the rotator type mirror. The invention further includes obtaining the three dimensional information of the target, based on a physical quantity corresponding to the projection angle of the reference light and on a physical quantity corresponding to the position of a projected image obtained when the mirror reflected reference light that scanned the target is captured by the imaging apparatus via the rotator type mirror.
摘要:
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.

Data defining an outline shape of a section, color-region image data and adhesion-region image data are generated, color toners are transferred onto a color region and an adhesion region on a sheet in accordance with the respective image data, the sheet is aligned on processed sheets and laminated thereon. Next, a laminated body of the sheets is bonded by heating and pressurizing, and the laminated and bonded sheets are cut along the sectional outline shape. Further, sectional shape data of a solid model are generated and a transparent toner is transferred as an adhesive onto the adhesion region of the sheet. Then, after aligning and laminating the sheet on the processed sheets, the transparent toner is melted to bond the sheets. Color toners are transferred onto the color region of the sheet and the sheet is cut along the outline shape. Furthermore, the color region is defined on a transparent sheet in accordance with the sectional shape of the solid model. After entirely covering the color region with a white toner layer, a three-primary-color toner layer in which the three primary color toners are spatially tone-distributed is applied to the color region, to form a colored layer of double-layered structure. Alternatively, a colored layer is formed of one-layered structure in which the white toner fills clearances of dots of the three primary color toners.
