Uren. J. & W.F.P. (1999) Surveying device, consisting of a visual structure for collimating a measuring position, a driving unit for performing scanning in a dimension range said visual structure, a distance-measuring unit comprising a radiance gesture detachment measuring scheme, an image pickup unit for captivating an illustration in the size range, an icon meting out unit for performing reflection meting out to haul out edges from the image pulled out up, and a control mathematics operation unit for choosing a position near the periphery as a measuring position on the figure singled out for controlling supposed distance-measuring unit to carry out surveying procedure of the measuring position. Uren. J. & W.F.P. (1999) Three-dimensional data is normally surveyed on an object as this flat within a predetermined range; however the past has gripped this model of surveying on an object such as building within a predetermined range, there have been disadvantages in the past in that much time was required and there was limitation in acquired amount of the surveying data because an operator must determine a measuring point and surveying operation must be carried out one point after another.

By the use of automatic instruments, surveying operation is automated, raster scanning is performed by determining a range with fine pitch, and a vast amount of 3-dimensional surveying data can be collected more quickly than in the operation by the surveying operator. A great number of measuring points are required and storage capacity o a storage device to store the data at the measuring points also must be large. In case unnecessary data is incorporated as measuring data, the continuity of the data may be lost, and the measurement must be repeatedly carried out in many cases.
