BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a distance measuring device for measuring the distance, position, size, inclination, etc. of an object such as land, buildings, piping, equipment, tools and the like at a distance.

[0002]

2. Description of the Related Art A conventional method for measuring the distance of a distant object is to measure the distance from two or more points separated by a theodolite / telescope, and to determine the distance between the horizontal angle, vertical angle, and azimuth angle measurement points at that time. The position, distance, dimensions, etc. of the object were calculated from the calculation. The conventional theodolite / telescope measurement at multiple points requires many measurement points and moves to the measurement points in many cases, and it takes time and effort to perform the measurement work, and measurement is difficult in places that are difficult or impossible to move. There was a problem that it became difficult. In order to solve this problem, the applicant has developed a distance measuring device in which two theodolites / telescopes are mounted at a fixed distance from the horizontal frame on the support base, but errors occur in angle measurement due to the deflection of the horizontal frame. A problem arose.

[0003]

The problem to be solved by the present invention is to solve these conventional problems, to reduce the number of measurement points, to make it easy to measure, and to measure the distance without blurring. Is to provide.

[0004]

Means for Solving the Problems The structure of the present invention which has solved the above problems is as follows: 1) A vertical frame is mounted on a support base, and the vertical frame can be turned and raised and lowered vertically and the horizontal angle and the vertical angle A distance measuring device characterized in that a pair of telescopes capable of outputting an angle signal or displaying an angle are arranged on the same vertical and separated by a predetermined distance. 2) A vertical frame is mounted on a support base, and the same vertical above and below the vertical frame. Above, a laser theodolite that can project laser light and output or display the projected horizontal angle and vertical angle of the projected laser light, and can output and display the horizontal angle and vertical angle that can be focused on the laser spot and the laser spot. A distance measuring device characterized by mounting the electronic theodolite at a predetermined distance 3) A vertical frame rotates around a vertical line with upper and lower telescopes attached Wherein mounted on the support leg platform in standing 1)
4) The distance measuring device according to 2) above, wherein the vertical frame is rotatably mounted on the support base around a vertical line on which the upper and lower laser theodolites and the electronic theodolite are mounted.

[0005]

According to the present invention, the measurement points are collimated by a pair of telescopes located on the same vertical line above and below the vertical frame. The position of the measurement point is determined by trigonometric calculation based on the horizontal angle and vertical angle of each telescope when collimated, and the vertical distance between the telescopes. The horizontal angle and the vertical angle may be electronically calculated and processed by a computer based on the angle signal from each telescope when collimated, or the angle of the telescope may be read visually and calculated manually or based on the data. May be entered and calculated. In this way, since the telescopes are on the same vertical, two position variables relating to the position between the telescopes can be reduced, and the calculation can be performed simply and accurately. Especially,
When using a laser theodolite and an electronic theodolite, a laser spot is formed at an arbitrary position on a distant object using the laser theodolite, and the electronic theodolite collimates the laser spot. Then, each angle signal of each theodolite is input, and distance calculation and position calculation are performed by a computer or the like. The use of the laser theodolite and the electronic theodolite enables measurement without placing a collimation mark or collimator on a distant object, so that an object in a place where a person cannot approach can be easily measured. In particular, if the vertical frame is mounted on the support base so as to be rotatable around the vertical line with the upper and lower telescopes or theodolites, distance calculation and position calculation are further simplified, and measurement with less error can be performed.

Thereafter, the laser theodolite 3 is directed to the measurement points P ₂ and P ₃ , and a laser beam is projected to create a laser spot on the surface of the predetermined object at the measurement points P ₂ and P ₃ . The collimation of the electronic theodolite 4 above the same vertical frame 2 is adjusted to the position of the laser spot.

Therefore, the distance and position of a distant object can be measured quickly and accurately. In particular, if a spot mark of a measurement point can be attached to a distant object by a laser theodolite as in this embodiment, the position and distance of the object in a place where a person is difficult to approach can be easily measured.

It is vertically mounted on a vertical frame 21 mounted on a head 20 via a camera platform 22. Also in this case, the rotation center of the vertical frame 21 coincides with the vertical line of the optical center of the telescopes 23 and 24. Further, the angle signals of the telescopes 23 and 24 are input to the notebook computer 25 in the same manner as in the first embodiment, and the position and distance are calculated in the same manner.

Other configurations and operational effects using telescopes 23 and 24 instead of 4 are the same as those of the first embodiment.

According to the present invention, the angle information of the theodolite / telescope is extracted by an electric signal and input to a computer such as a personal computer. In addition, a human reads the angle from an angle display attached to the computer, and the numerical value of the angle is read. It can be input to a computer such as a personal computer via a keyboard. This is a difference in the input method between online and whether a human intervenes in the middle, and includes both modes.
