Patent attributes
A surveying instrument includes: a survey system; an image sensing system, including first and second image sensing units, the second having an angle of view wider than that of the first; horizontal and vertical angle drivers to rotate the survey and image sensing systems around a surveying instrument vertical and horizontal axes, respectively; a data storage part; an angle detecting part; and a control unit to cause an image, based on image data the first or second generates after imaging, a design data object for showing the design data portion locations included in the image, and coordinate measurement point objects for showing the coordinate measurement points locations, to be surveyed, corresponding to the design data portion included in the image, to appear on a representation device in response to the design data stored in the data storage part and the detected angle.
