Abstract

PURPOSE:To obtain a system for efficiently executing the survey of a number of points by an operator by measuring angles and ranges by remotely controlling an angle and range measuring instrument and obtaining surveyed data. CONSTITUTION:A surveying system is constituted by a surveying instrument 1 composed of an approximate direction measuring instrument 3 and an angle and range measuring instrument 4 with a controller and a target instrument 2 composed of a collimator 7, a projector and a corner prism. The instrument 1 is mounted on a surveying point near the center of a surveying area with a good perspective. Then, the instrument 2 is mounted on another surveying point. A laser beam is emitted by using the collimator 7 of the instrument 2 and the measuring instrument 3 and the instrument 1 is accurately directed in the direction of the instrument 2 in the order of (1)-(2) as shown. In this condition, the collimating point of the collimator 7 and the projected point of the beam 13 are changed from a corner prism 5 with an incident angle measuring function to the center point of a telescope 11 and a signal is fed to the angle and range measuring instrument 4 to accurately measure angles and ranges. At this time, the quantity of a deviation 16 from the center of the optical axis of the telescope 11 is measured by an image sensor 18 in the telescope 11 of the angle and range measuring instrument 4 and a measured angle value is corrected by the quantity of the deviation 16 to enable a correct angle value to be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION a. Field of Industrial Application This invention relates to a surveying system that allows one person to survey.

b. Conventional technology In conventional surveying, an engineer who handles the equipment is placed at the point where the angle measuring instrument or angle measuring and ranging instrument is installed, and the point is selected and a reflector or ball is placed at that point. A minimum of two engineers were required to carry out the surveying work, with engineers assigned to each site for the installation.

C1 Problems to be Solved by the Invention In this invention, one engineer first installs a surveying device at the point where angle and distance measurement is to be performed, and after installation, the problem to be solved by the invention is solved without placing any personnel in that position. By selecting a point, setting up a reflector or a ball, and sending a signal from that point, the angle and range finder is remotely controlled to perform angle and distance measurements and obtain survey data.

d. Means for solving the problem The means for solving the problem will be explained with reference to FIG. 1 and FIG. 2.

This system consists of a surveying device consisting of a general direction measuring device and an angle and range finder with a control function, and a targeting device consisting of a reference telescope, a projector, and a corner prism.

The surveying device has a polygonal prism shape as shown in Figure 1, and its polygonal surface is a corner prism with an incident angle measurement function (application 62).
-14233) attached to one surface and several surfaces attached with light arrival detection sensors, the image sensor is attached to the focal position inside the telescope, and the optical axis at the focal position of the incident light is The center line of the corner prism with the angle of incidence measurement function and the optical axis center line of the telescope of the angle and range finder are placed on top of the angle and range finder with a control function that can measure the amount of deviation from the center. They are made by attaching them in parallel lines. The target device, as shown in Figure 2, includes a reference telescope that standardizes the projection point, a projector equipped with a laser light source and optical system that can project light onto the same optical axis as that of the reference telescope, and It consists of a corner prism, and is made so that the reference and laser light can be projected in the direction in which the center line of the corner prism extends through the intersection of the three reflecting surfaces of the corner prism.

e, action The operation will be explained with reference to FIG. 3 and FIG. 4.

To conduct a survey, first set up this surveying device at a survey point with good visibility near the center of the survey area.

Next, the target device is installed at another survey point, and the target device is installed at another survey point and
The target device's standard telescope is used to standardize the surveying device's general direction measuring device, and a laser beam is emitted. The laser light is projected onto a light arrival detection sensor of a certain side of the general direction measuring device or onto a corner prism with an angle of incidence measurement function.

When the light is projected onto the sensor, the light is detected by the sensor, so the general direction in which the target device is installed can be determined, and the control function allows angle measurement as shown in Figure 3-(2). The range initiator is rotated to point in the general direction of the targeting device. At this time, the corner prism with an incident angle measurement function is oriented in a direction directly facing the target device. or,
If the beam is projected onto a corner prism with an incident angle measurement function from the beginning, the same direction will be maintained. If the laser beam is subsequently projected, the laser beam will be projected onto the corner prism with an incident angle measuring function, so the direction of the incident angle will be measured by the incident angle measuring function.

The measurement results are used as control data for the horizontal angle, and for the altitude angle, the difference in height between the center of the telescope of the corner prism with an incident angle measurement function and the angle and range finder is corrected, and the angle and range finder is adjusted. The angle and range finder is controlled using the value converted to the value of the reference axis of the telescope as the control data, and the angle and range finder is controlled.
As in 3), the telescope rotates to point more precisely at the target device. When the angle and range finder is facing in this direction, move the reference point of the reference telescope of the target device and the point where the laser beam is projected from the corner prism with the incident angle measurement function to the center point of the angle and range finder's telescope. Then, a signal to start angle measurement and distance measurement is sent to cause the angle measurement and distance measurement device to perform angle measurement and distance measurement.

At this time, the angle measurement direction of the angle and range finder may not accurately refer to the center of the target device, but since the laser beam is projected from the target device side, as shown in Figure 4. The amount of deviation of this light point from the center of the optical axis can be measured using the image sensor in the telescope of the angle and range finder, so by correcting this amount to the measured angle value, the correct angle value can be obtained. Desired.

Regarding the distance measurement value, since the distance measurement error due to a small amount of directional deviation can be ignored, the distance measurement value can be directly determined as the correct distance value.

f. Effects of the invention According to this method, one person can carry out the survey of many points,
It can provide an extremely effective surveying system.
