摘要： The present invention relates to a tracker and a surveying apparatus comprising the tracker, which improve the reliability of tracking a target. The tracker comprises a first imaging region having a plurality of pixels for taking a first image of a scene including the target; a second imaging region having a plurality of pixels for taking a second image of a scene including the target; a control unit to receive a timing signal indicating a time duration during which an illumination illuminating the target in the scene is switched on and off, control the first imaging region to take the first image of the scene when the timing signal indicates that the illumination unit is switched on, and control the second imaging region to take the second image when the illumination is switched off; and a read out unit configured to read out the first image from the first imaging region and the second image from the second imaging region and to obtain a difference image.

摘要： A scanning surveying system comprises a base 5, an alidade 3 mounted on the base, a first motor 6 to rotate the alidade about a first axis 9, a rotating mirror 21 rotatable about a second axis 16, a second motor 23 to rotate the mirror. An optical distance measuring unit 11 is configured to direct measuring light onto the rotating mirror such that it is reflected towards objects and to receive measuring light back from these objects via the rotating mirror. The system further comprises a camera 81 and a controller for controlling the first motor based on the images recorded by the camera such that the measuring light is reflected from the rotating mirror in a direction corresponding to a selected location within the image.

摘要： For swift and secure determination of a measurement error a first digital image is obtained using an image sensor, wherein a line of sight of an optical arrangement is oriented in a first face direction. A characteristic image area in the first digital image on an image sensor is determined. A second digital image is then taken with a line of sight of the image sensor oriented in a second face and the characteristic image area defined in the first image is searched in the second digital image, the first or the second digital image is rotated in the image plane by 180° . Then in the second digital image the position of the characteristic image area is determined. And offset between the characteristic image area in the first digital image and the characteristic image area in the second digital image is determined.

摘要： A method for aligning two surveying instruments in a common space in a process that uses an autocollimation of a collimated light beam transmitted by a first surveying instrument and reflected by a second surveying instrument. In the alignment process, the first surveying instrument may emit a collimated light beam towards the second the surveying instrument and receive a reflection of the collimated light beam from the second surveying instrument in an autocollimator. The reflection may be generated for example by a mirror at the second surveying instrument. When the light beam is reflected such that autocollimation of the collimated light beam is achieved at the first surveying instrument, the first and second surveying instruments are in a predetermined positional relation with respect to one another. With a known predetermined positional relation between the reflecting mirror and the line of sight of the second surveying instrument, measurements by both surveying instruments can be made in a common coordinate system.

摘要： A surveying instrument comprises a base; an alidade rotatable about a first axis relative to the base; and an optical measuring instrument having a measuring axis rotatable about a second axis relative to the alidade. A beam path can be provided for a light beam using components including a light source, lenses, mirrors, beam splitters, and a position-sensitive detector. The surveying can be calibrated by performing plural measurements at different orientations of the alidade relative to the base and different orientations of the measuring instrument relative to the alidade using the above components.

摘要： An optical surveying instrument is provided with an optical arrangement that includes at least one lens and the viewing element defining a viewing direction in the field of view. The distance measurement unit emits light beam towards the field of view and measured the distance to an object in the field of view based on a reflection of the light beam from the object. A movable mirror is arranged to direct the light beam towards the object and a mirror control unit is provided for reading calibration values from a calibration value memory and for moving the movable mirror using the calibration values to adjust the direction of the light beam to be aligned with the viewing direction.
