  • Patent number: 7177460
    Abstract: A sophisticated surveying instrument consists of a workbench, a coordinate board and two optical sensors. The workbench fastened to a coordinate board with several square grids of equal size forms a connected surveying instrument. Inside the grid there is a readable icon recognizable for the apex coordinate. One of the two optical sensors projects against the workbench to define the starting point and end point of the object while the other against the coordinate, so as to identify the recognizable icon within the projected pixel block on the coordinate board and enter the projected image into an electronic computer for comparison, analysis and conversion, thus identifies the position of the pixel block's center on the coordinate board, defining the corresponding value of the starting point and end point.
