A surveying apparatus is provided that includes a telescope block, a support block, and an imaging unit. The telescope block includes a sighting telescope and is rotatably supported about a first axis. The support block rotatably supports the telescope block about the first axis. The imaging unit is provided inside the telescope block. The imaging unit comprises an image-display device and at least one of an image data output device and an image data recording device.

Surveying apparatus

A surveying apparatus is provided that includes a sighting telescope, an imaging device, and an external orientation parameter calculator. The sighting telescope is rotatable about a horizontal axis and a vertical axis. The imaging device is integrally rotated with the sighting telescope and the imaging device has an optical axis that is different from the collimation axis. The external orientation parameter calculator calculates external orientation parameters of stereo images that are obtained by the imaging device in an erecting observation and in an inverse observation in terms of the position of the optical axis with respect to the collimation axis, and the sighting directions in the erection observation and in the inverse observation.

A surveying instrument includes a sighting telescope optical system, a distance measuring system which outputs first data, a phase detection autofocus system which and outputs second data, and an AF driver which moves a focusing lens of the sighting telescope optical system to bring the sighting object into focus in accordance with one of the first data and the second data. A surveying instrument is also disclosed, which includes a sighting telescope and an AF drive unit which is provided separately from the sighting telescope, wherein the AF drive unit can be mounted to and dismounted from a body of the surveying instrument.

Surveying instrument having an optical distance meter and an autofocus system, and a surveying instrument having a detachable autofocus system

A surveying instrument having an AF apparatus, provided with a focusing lens and a collimation telescope, includes a focus detector for detecting a focus state through the collimation telescope, and a controller for moving the focusing lens of the collimation telescope to a focal position, based on the focus state detected by the focus detector. The surveying instrument includes a single focus mode at which only one detection of the output of the focus detector and only one control operation of the controller based on the detected output are carried out, and a continuous focus mode at which a plurality of detections of the output of the focus detector and a plurality of control operations of the controller based on the detected outputs are sequentially carried out, the single focus mode and the continuous mode being selectively performed.
