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 distance measuring system comprises a radiation source, a radiation detector, a measuring lens system, a first damping filter, a second damping filter and an actuator. The radiation source is constructed to emit optical radiation and the radiation detector is constructed to detect optical radiation. The measuring lens system is designed to project optical radiation to a target and to conduct optical radiation reflected by the target to the radiation detector. The first damping filter has a constant damping and can be arranged in a beam path between the radiation source and the measuring lens system. The second damping filter has an adjustable damping and can be arranged in a beam path between the measuring lens system and the radiation detector. The actuator is mechanically coupled to the first and also to the second damping filter and is constructed to move the first and the second damping filter in common.

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.
