摘要： The present invention relates to a surveying apparatus for surveying an object as well as a surveying system comprising the surveying apparatus having a simple and compact optical setup. The surveying apparatus comprises a lens arrangement including at least one movably arranged focus lens element for focusing to sight an object; an imaging unit configured to obtain an image of at least a part of the object; a distance measuring unit configured to measure a distance to the object along the optical axis of the distance measuring unit; and a beam splitter/combiner configured to combine a part of the optical imaging path of the imaging unit and a part of the optical distance measuring path of the distance measuring unit so that the optical axis of the imaging unit and the optical axis of the distance measuring unit are at least coaxially arranged with the optical axis of the lens arrangement between the lens arrangement and the beam splitter/combiner.

摘要： The invention relates to optical surveying such as in building construction, road construction, landscaping and similar. A first image sensor obtains in a first wavelength range a first image of a scene within a field of view captured by an optical arrangement such as a telescope. A light emitter emits light in a second wavelength range and a second image sensor obtains a second image of the field of view in the second wavelength range. A target position of a reflecting target is found in the first image by detecting a known image pattern of the reflecting target in the first image. A region of interest in the second image is then a defined based on the identified target position in the first image, for detecting a reflector position of a reflector of the reflecting target in the region of interest. With the invention it becomes possible to improve the identification of a reflective target at reduced processing time, even if reflections from other objects than the reflective target are present.

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 an image sensor arrangement having an imaging region composed of a plurality of pixels arranged in a matrix of columns and rows. The imaging region is arranged to take an image of a scene including the target. A controller receives or generates a timing signal indicating a time duration during which an illumination unit is switched on and off, controls the imaging region to take an image of the scene when the illumination unit is switched on, and reads out a subgroup of neighboring columns or rows constituting a stripe window of the imaging region so that an image section including the target is obtained, controls the imaging region to take another image of the scene when the illumination unit is switched off, and reads out another subgroup of neighboring columns or rows constituting another stripe window of the imaging region so that another image section including the target is obtained, and calculates a difference image section by determining a difference between the pixel values of the pixels of the image section and the other image section.

摘要： Reflective target for surveying instruments having a plurality of planar reflective sections arranged to form a shape having a target axis. Each reflective section includes a plurality of prisms, each prism constituted by a corner cube having three surfaces oriented perpendicular to one another and forming a base for receiving incident light, and each of the prisms is oriented such that a common edge formed by two of the three surfaces of the prism is oriented such that the common edge and the target axis or a line parallel to the target axis lie in a common plane.

摘要： A device for measurement by means of a light ray is equipped with a covering device for reducing stray light. The device comprises an array of lenses along an optical axis; a prism attached to one of the lenses with a slanted surface for coupling of the light ray incident from a light source placed lateral to the optical axis, onto the optical axis, so that the light ray can pass through the array of lenses along the optical axis; a receiver for receipt of a share of the light ray reflected by an object; and a covering device for at least one area of the prism that scatters a share of the light ray as stray light to the receiver.

摘要： An optical instrument and a method for obtaining distance and image information of an object is disclosed to improve the speed and accuracy of data acquisition. The instrument comprises a camera, positioning unit, distance measuring unit, lens arrangement and control unit. The camera acquires images of an object and the control unit defines an area to be scanned as well as an object feature of the object, wherein measurement pixels corresponding to positions on the object may be defined in the area with an increased density of measurement pixels at the object feature. Subsequently, the distances to the object at the selected positions of interest are measured.

摘要： A distance-measuring system includes a light source, a light detector, and measuring optics for projecting light emitted by the light source to a target and for guiding light reflected from said target towards the light detector. The distance-measuring system also includes reference optics for guiding light emitted by the light source within the system towards the light detector as internal reference light and a variable attenuator for adjusting intensity of light incident on the light detector. The variable attenuator includes an attenuating filter arranged in a beam path between the measuring optics and the light detector and an actuator coupled to the attenuating filter for moving the attenuating filter. The distance-measuring system further includes an optical selector coupled to at least one of the actuator or the attenuating filter and moved by the actuator together with the attenuating filter.

摘要： An optical instrument and a method for obtaining distance and image information of an object is disclosed to improve the speed and accuracy of data acquisition. The instrument comprises a camera, positioning unit, distance measuring unit, lens arrangement and control unit. The camera acquires images of an object and the control unit defines an area to be scanned and measurement pixels of an object in the image, wherein the measurement pixels are converted into an approximation of coordinates of positions to be measured assuming a default distance to the positions, and the optical axis of the lens arrangement is adjusted sequentially onto the positions to be measured. After measuring the distances to the positions, the coordinates are recalculated increasing the accuracy of the coordinates.
