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 de...
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. Tifadi, T. & Booth, D.W. (1997)
Modern Surveying Techniques
To obtain the site configuration through the survey, the contemporary survey technique comprises of a technique that acquires an image of a measurement range, a step of extracting edges by image dispensation of the image, a step of selecting measuring points on both sides of the edge from the image, and a step of performing surveying maneuver on the measuring points. Steps that excludes irregular edge data from the extracted edges, exclusion of edge data including fine alignment above a certain level is excluded from the extracted edges. The joining of two or more image data based on the extracted edge data. The extracted edges are two edges crossing each other and a technique that comprises a step of calculating an intersection of the edges, a step of selecting measuring points near the intersection of the edges, a step of selecting measuring points near the intersection, and a step of performing surveying operation on the measuring points.Tifadi, T. & Booth, D.W. (1997)
Surveying near the edge on the extracted edges is done, and the step of surveying is near the edge and a step of calculating a plane is surrounded by the edges, and a step of calculating surveying data of any desired point of the plane from the result of calculation. Nickerson, et al. (1995).
Also the modest contraption offers a surveying appliance, which comprises an optical system for collimating a measuring point, a driving unit for performing scanning in a dimensional range of the visual
