Surveying Instrument
First Claim
1. A surveying instrument comprising:
- a measuring unit for performing a distance measurement by projecting a distance measuring light toward an object to be measured and by receiving a reflected distance measuring light from said object to be measured, an image pickup unit having an image pickup optical axis running in parallel to a projection optical axis of said distance measuring light and for picking up an image including said object to be measured, an attitude detecting unit provided integrally with said image pickup unit, and an arithmetic processing unit, wherein said attitude detecting unit has tilt sensors for detecting a horizontal and a relative tilt angle detecting unit for tilting said tilt sensors so that said tilt sensors detect the horizontal and for detecting a tilt angle of said measuring unit with respect to the horizontal in a condition where said tilt sensors detect the horizontal, and wherein said arithmetic processing unit calculates a tilting of said image with respect to a vertical based on a detection result of said attitude detecting unit and displays vertical lines in said image acquired by said image pickup unit based on this calculation result.

Abstract
The invention provides a surveying instrument, which comprises a measuring unit for performing a distance measurement by projecting a distance measuring light toward an object to be measured, an image pickup unit for picking up an image including the object to be measured, an attitude detecting unit provided integrally with the image pickup unit, and an arithmetic processing unit, wherein the attitude detecting unit has tilt sensors for detecting a horizontal and a relative tilt angle detecting unit for detecting a tilt angle of the measuring unit with respect to the horizontal, and wherein the arithmetic processing unit calculates a tilting of the image with respect to a vertical based on a detection result of the attitude detecting unit and displays vertical lines in the image acquired by the image pickup unit based on this calculation result.
