Abstract: A surveying system that comprises a position relation calculating processor, a correspondence establishing processor, and an image processor is provided. The position relation calculating processor calculates a positional relation between a coordinate system to which measurement information of a measurement point refers and an image of a surveying field, where a staking point is included. The correspondence establishing processor establishes correspondence between three-dimensional position information of the staking point and two-dimensional position information of a point corresponding to the staking point on the schematic image. The image processor superimposes a symbol that indicates the position of the staking point on the schematic image in accordance with the above correspondence.

Abstract: A first frame holds a second frame which holds two correction lenses. Two guide pins, fixed on the first frame, pierce through two guide holes extending in a lengthwise direction. A first actuator including a motor and a shaft moved in the lengthwise direction in accordance with the rotation of the motor moves the first frame in the lengthwise direction. One of the guide pins is in contact with one end of the shaft. The tip end of a pressing member mounted on another of the guide pins is in point-contact with another end surface of the shaft, pressing the shaft to the another guide pin. In accordance with the movement of the shaft, the first frame moves in the lengthwise direction being guided by the guide pins and holes. A second actuator for moving the second frame in the lateral direction is structured similarly.

Abstract: An automatic surveying system is provided that comprises a surveying device, a collinear-line calculating processor, a sighting direction control processor, and an object-point searching processor. The collinear line calculating processor obtains a collinear line for an arbitrarily designated point on a schematic image of which the positional relation to the surveying device is known. The sighting direction control processor controls the surveying device to sight along the collinear line. The object point searching processor searches for an object point where the position of the object point can be determined as a point on the collinear line. This is executed by measuring the sighting direction with the surveying device while carrying out the sighting direction control process. Further, a position obtained by the object point searching processor coincides with an object point that corresponds to the designated point.

The position relation calculating processor calculates a position relation between a coordinate system to which three-dimensional coordinates of a measurement point refer and a schematic image of a surveying field. Here, the schematic image includes the measurement point. The correspondence obtaining processor obtains a correspondence between the three-dimensional coordinates of the measurement point and the two-dimensional coordinates on the schematic image, corresponding to the measurement point.

Abstract: Binoculars are provided with correction lenses for correcting a tremble of a focused image and stepping motors which unitarily move the correction lenses. With respect to a lengthwise direction, a sensor detects an angular speed of a tremble of optical axes of the binoculars. After being amplified and converted to digital data, output of the sensor is input to the microcomputer. Based on the angular speed, the microcomputer calculates a necessary pulse number of driving pulse signals. The necessary pulse number indicates the number of pulses to be applied to the stepping motor in order to correct the tremble. Based on the necessary pulse number, a circuit selects one pulse group among pulse groups of different pulse rates. The circuit outputs the selected pulse group to a motor driver which drives the stepping motor for a predetermined period. With respect to a lateral direction, similar operations are carried out.

The telescope further includes an indication system which indicates, by a displaying device, the values of the distance, altitude difference and azimuth angle.

Abstract: A change-over shutter for an optical range finder employs at least two slits for measurement light, one of which is employed during long distance measurements and the other of which includes a light reduction member and is employed for short distance measurements. The arrangement advantageously eliminates measurement error caused in short distance measurements due to light secondarily reflected from the light emitting element.
