Abstract
It is premised that a surveying instrument at least includes an elevation angle measuring part 30 measuring an elevation angle relative to an object to be measured. Under this premise, the surveying instrument includes an error detecting part 35, 54, 55 detecting a vertical-axis error Δθ reflected in an elevation angle measured by the elevation angle measuring part 30 and a correction processing part 50 receiving an elevation angle measured by the elevation angle measuring part 30 and outputting as an elevation angle an angle acquired by cancelling the vertical-axis error Δθ detected by the error detecting part 35, 54, 55 form the elevation angle.
