In the method of obtaining captures images, there is overlaps in images in the flight direction and in a direction (cross direction) that crosses the flight direction. A predetermined number of the captured images containing overlapping sections that include a target point are selected out of the obtained images in the flight direction and/or the cross direction. From the overlap sections of these captured images, selected images are obtained by selecting image sections within a specific range that contains the target point. Using the flight direction and the cross direction as axes for a matrix, the selected images are arranged to create an aerial photograph data set.

Method of producing and displaying an aerial photograph data set

The present invention relates to a surveying instrument for measuring the distance to a target to be measured, a horizontal angle, and a vertical angle by use of reflected light. An imager can be connected to the surveying instrument. In addition, an arithmetic processing means can determine a three-dimensional position of a plane part by determining from at least three measuring points an equation that includes the plane part as the target to be measured, and then by associating digital image data to which the plane part belongs with the equation so that the plane part is identified.

Surveying instrument and electronic storage medium

Airborne photographing apparatus

A stereoscopic photographic measuring device which can execute an analysis of a stereoscopic photograph very efficiently. The stereoscopic photographic measuring device comprises a table for receiving a set of stereoscopic photographs thereon, and an optical system body constructed for movement in two-dimensional directions relative to the table. The table has a plane coordinate reading means provided thereon for reading coordinates of the stereoscopic photographs while the optical system body has provided thereon a stereoscope unit for observing the stereoscopic photographs in a stereoscopic vision, first and second cursors disposed within a range wherein the first and second cursors can be observed by way of the stereoscope unit, and a distance adjusting means for adjusting a distance between the first and second cursors. The device further comprises an outputting means for outputting data read in by the first cursor and the plane coordinate reading means and data read in by the second cursor and the plane coordinate reading means to a data processing device.

Stereoscopic photographic measuring device

A coordinates measuring apparatus comprising a detecting unit constituted by an optical system for obtaining an image of an object and a detecting system having a plurality of arrayed detecting elements disposed in such a manner that respective detecting signals are superposed at the position of said image, a control unit for taking out data from each of said arrayed detecting elements, and a storage unit for storing the data of each array taken out from said control unit.

Apparatus and method for determining the coordinates of a

A shape measuring apparatus is disclosed. It comprises a pattern portion having a pattern in which pattern elements are arranged in the pitch width direction according to a predetermined rule so that a plurality of N codes can be distinguished with respect to one another; a projecting portion having a moving portion for moving the pattern in the pitch width direction according to a rule and projection optical system for projecting the pattern onto an object to be measured; a detecting portion for detecting a first detection data and a second detection data by measuring a surface information of the object to be measured on which the pattern is projected from two different directions every time the pattern is moved by the moving portion; an extracting portion for extracting a first position data and a second position data corresponding to a point position of the object to be measured from the first and second detection data respectively; and a calculating portion for calculating a coordinate of the point position corresponding to the first position data of the object to be measured from the first position data and the second position data.
