PROBLEM TO BE SOLVED: To improve the survey precision by precisely measuring the distances of the reference point members of the target for photographic survey. SOLUTION: This instrument 100 is equipped with a photographing device 110 and a personal computer(PC) 150. The photographing device 110 is equipped with three cameras 112, 114, and 116, which photograph three reference-point members of the target 10. The PC 150 stores photographed images obtained by the photographing device 110 in a memory 156 through a capture board 152. The CPU 154 of the PC 150 processes the photographed images to calculate the distances of the reference-point members and outputs them to the target 10. The microcomputer 38 of the target 10 stores the distances of the reference- point members in a nonvolatile memory 36. |
