Surveying instrument and three-dimensional camera

A three-dimensional camera in which a surveying instrument and an image pickup device are integrated, wherein said surveying instrument comprises;

• a light emitting element for emitting a distance measuring light, a distance measuring light projecting unit for projecting said distance measuring light, a light receiving unit for receiving a reflected distance measuring light, a photodetection element for receiving the reflected distance measuring light and for producing a photodetection signal and a distance measuring unit for performing a distance measurement based on a light receiving result from said photodetection element, wherein said surveying instrument further comprises a first optical axis deflecting unit disposed on a projection optical axis of said distance measuring light for deflecting an optical axis of said distance measuring light at a deflection angle as required and in a direction as required, a second optical axis deflecting unit disposed on a light receiving optical axis for deflecting the reflected distance measuring light at the same deflection angle and in the same direction as said first optical axis deflecting unit and a projecting direction detecting unit for detecting a deflection angle and a deflecting direction by said first optical axis deflecting unit, wherein it is so arranged that said distance measuring light is projected through said first optical axis deflecting unit and said reflected distance measuring light is received by said photodetection element through said second optical axis deflecting unit and a three-dimensional data of a measuring point is obtained based on a distance measuring result of said distance measuring unit and a detection result of said projecting direction detecting unit, wherein said image pickup device comprises an arithmetic processing unit, an image pickup optical axis capable of coinciding said projection optical axis with a center of an acquired image, and an image pickup element, wherein it is so arranged that said image is equal to or approximately equal to a deflection range of said first optical axis deflecting unit and said second optical axis deflecting unit and a position of each pixel of said image pickup element can be specified by a coordinate system with said image pickup optical axis as an origin point, said arithmetic processing unit enables said first optical axis deflecting unit to scan said deflection range by a distance measuring light and specifies said measuring point positioned on a scanning locus on said image, and acquired images having three-dimensional data per each pixel by associating three-dimensional data of said measuring point acquired by said surveying instrument with the position of said measuring point in said image acquired by said image pickup device.
