PROBLEM TO BE SOLVED: To solve a problem in which an object to be surveyed and a visual level are positioned on the same worktable and when the worktable is on a work ship or a floating body on the sea the inclination of the instrument cannot be corrected quickly and accurately in a conventional standard attitude correction method and apparatus for a measuring instrument. SOLUTION: In the standard attitude correction method and apparatus for a measuring instrument, a monitor-equipped collimating scope is affixed to the measuring instrument mounted on a worktable having an object to be surveyed and both-side surveying reference points. The both-side horizontal direction is collimated by the collimating scope. The standard attitude of the measuring instrument is corrected in accordance with the visual field position of each surveying reference point obtained by the collimating scope.
