Tacheometer telescope

Tacheometer telescope for optical distance measurement in geodetic, industrial and construction surveying, comprising

• an optical telescope lens (11);
• a motorized theodolite as the telescope support;
• an electronic unit for controlling and regulating the motorized theodolite axes;
• a distance measuring combination (23) for distance measurement via at least one reflector or at least one target mark to a target object (16) to be surveyed, on the one hand, and to a natural target object (16) without such target marking, on the other hand, with the aid of, in each case, a first (19, 20a) and second sensor means (19, 20b) for at least one beam emitted by a transmission means (S1, S2 or S3);
• and
• comprising an evaluation unit (24), connected to the distance measuring combination (23), for receiving a signal which corresponds to the respective beam reflected by the target object and for determining the distance from transit time and/or phase position relative to the transmitted signal;
• characterized in that in addition at least a third optoelectronic sensor means (S1, 21, 27) for automatic target recognition, having a processing unit for extensive sensors (27) with angle determination, is provided as a further evaluation unit, that the target axes of all these sensor means (29, 20, 23, 21) coincide and form a common effective axis (A), and that the transmitted and the received beams have a coaxial effect relative to the sensor means (29, 20, 23, 21) of the image processing unit (27) and of the distance measuring combination (23).
