Abstract: An imaging apparatus includes: an image-acquiring unit that acquires an image of an object of photography through a lens; an image display unit that displays the image acquired by the image-acquiring unit to an operator; an angular movement amount detecting unit that detects an angular movement amount of the imaging apparatus; an image movement amount calculation unit that calculates an image movement amount based on the angular movement amount detected by the angular movement amount detecting unit; and an object-position display unit that displays a current position of the object of photography superimposed onto the image displayed by the image display unit based on the image movement amount calculated by the image movement amount calculation unit.

Abstract: A surveying system is provided that comprises a position relation calculating processor and a correspondence obtaining processor. The position relation calculating processor calculates a position relation between a coordinate system to which three-dimensional coordinates of a measurement point refer and a schematic image of a surveying field. Here, the schematic image includes the measurement point. The correspondence obtaining processor obtains a correspondence between the three-dimensional coordinates of the measurement point and the two-dimensional coordinates on the schematic image, corresponding to the measurement point.

Abstract: A surveying system that comprises a position relation calculating processor, a correspondence establishing processor, and an image processor is provided. The position relation calculating processor calculates a positional relation between a coordinate system to which measurement information of a measurement point refers and an image of a surveying field, where a staking point is included. The correspondence establishing processor establishes correspondence between three-dimensional position information of the staking point and two-dimensional position information of a point corresponding to the staking point on the schematic image. The image processor superimposes a symbol that indicates the position of the staking point on the schematic image in accordance with the above correspondence.

Abstract: An automatic surveying system is provided that comprises a surveying device, a collinear-line calculating processor, a sighting direction control processor, and an object-point searching processor. The collinear line calculating processor obtains a collinear line for an arbitrarily designated point on a schematic image of which the positional relation to the surveying device is known. The sighting direction control processor controls the surveying device to sight along the collinear line. The object point searching processor searches for an object point where the position of the object point can be determined as a point on the collinear line. This is executed by measuring the sighting direction with the surveying device while carrying out the sighting direction control process. Further, a position obtained by the object point searching processor coincides with an object point that corresponds to the designated point.

Abstract: An apparatus for establishing correspondence between a first and a second image which includes the same object is provided. The apparatus comprises a point designator, a first image extractor, and a corresponding point searcher. The point designator is used to designate a point on the first image. The first image extractor extracts a predetermined area of an image surrounding the designated point as a first extracted image. The corresponding point searcher searches a point on the second image, which corresponds to the designated point on the first image by image matching between the first extracted image and the second image. Further, the resolutions of the first and second images are different from each other.

Abstract: A schematic illustration drawing apparatus utilized for drawing a schematic illustration corresponding to a image that is captured by a digital camera or scanner is provided. The apparatus comprises an image indicating processor, drawing processor, transmittance setting processor, and adjusting processor. The image indicating processor indicates the image and illustration on the screen of a display as a first and second layer, so that the illustration is superimposed on the image. The brightness and contrast of the image in the first layer is adjusted by the transmittance of the second layer that is set by the transmittance setting processor, so that the illustration is made prominent from the image. As a result, an operator can easily trace the image on the screen with the drawing processor, as if the operator were drawing the illustration on tracing paper.
