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： Methods, apparatuses and computer programs are disclosed for estimating, or at least for generating information usable to estimate, the heading of at least one axis (20) of interest of a rigid body (10). Rigid body (10) is equipped with an antenna (30) of a navigation satellite system (NSS) receiver, and with sensor equipment (40) comprising sensors such as a gyroscope, an angle sensor, and accelerometers, depending on the form of the invention. Rigid body (10) is subject to a known motion comprising causing a point's horizontal position to change, the point being referred to as "point B", while keeping another point's position, the point being referred to as "point A", fixed relative to the Earth (50). Considering the motion constraint, an estimation of the heading is generated using sensor equipment data and NSS receiver data. The estimation of the heading may for example be used to estimate the position of any point of rigid body (10).

摘要： The present disclosure relates to a measuring instrument and a method implemented in such a measuring instrument. The measuring instrument includes an image sensor, an actuator, a control unit and a processor. The actuator is arranged to move a field of view of the image sensor. The control unit is configured to cause the image sensor to capture at least one digital image during motion of the field of view of the image sensor by the actuator. The exposure time for capturing the digital image is longer than an identifiable section of a regulating pattern for modulation of an optical radiation either emitted or reflected by at least one target. The processor is configured to process at least a portion of the captured image for detecting in the at least one portion the identifiable section of the regulating pattern. Such a measuring instrument is advantageous for detecting and/or identifying a target in the vicinity of the instrument.
