The present invention relates to a position measuring instrument for, for example, scanning a photoreceiver as a target to be measured, and more particularly to an automatic position detection instrument capable of emitting distance measuring light and tracking light while turning directions of the distance measuring light and the tracking light so that three-dimensional measurement of a light receiving position is performed, and further capable of transmitting measured data to a photoreceiver provided on a target. A light source unit emits measuring light, and then a light receiving unit receives its reflected light. A scanning means emits measuring light in a scanning direction, and leads its reflected light to the light receiving unit. An angle detector detects a rotational position of the scanning means. The measuring light includes distance measuring light expanding in a fan-shaped manner. Its reflected light can be used to measure a distance to a reflector.

A position determining system is disclosed, which has a simplified configuration capable of producing a plurality of phantom planes simultaneously. The improved system according to the present invention consists of a light receiving and sensing device that includes a body having means for sending data on elevation- and depression-angles and horizontal angles, and a phantom plane determining function for determining phantom planes, so as to display or output differential angles of elevations and depressions in relation with the phantom surfaces produced from the data received from the body.
摘要:
An incremental encoder has a rotor provided with a plurality of indices and is capable of detecting a reference point or a zero point without turning the rotor one full turn. Graduation lines of a main scale are counted until a detector detects an index I.sub.1 and the next index I.sub.2, the angle or the distance between the reference point and the index I.sub.2 is determined on the basis of the counted number of graduation lines of the main scale, the angle or the distance between the position of the index I.sub.2 and an optional position is determined on the basis of the corresponding number of graduation lines of the main scale, and the angle or the distance between the reference point and the optional position is determined by adding the angle or the distance between the reference point and the position of the index I.sub.2 to the angle of the distance between the position of the index I.sub.2 and the optional position.
摘要:
A base station is installed in a predetermined area where a large number of target points are studded around the station. When the operator moves a mobile station around the base station, display means is provided for both or either of the base station that guides the operator and the mobile station, and a display screen of the display means displays 2 kinds of a Forward (foreground) mode and a Back (background) mode. In the Forward (foreground) mode, the display screen of the display means displays a landscape in a forward direction (opposite direction to the mobile station by 180° when seen from the base station) of the operator (mobile station) when the operator sees the base station from the current position of the mobile station, or from the next target point if the operator reaches the next target point. In the Back (backward) mode, the display screen of the display means displays the landscape in a backward direction (direction of the operator and the mobile station when seen from the base station) of the operator (mobile station) when the operator sees the base station from the current position of the mobile station, or from the next target point if the operator reaches the next target point. The relationship between the mobile station and the next target point is displayed on an imaginary landscape in an imaginary manner so that the operator can see the direction and distance for movement.
