Embodiment 1

[0029] as attached figure 1 , 2 As shown, a double-beam laser measuring instrument includes a first laser measuring instrument 1 and a second laser measuring instrument 2, and the first laser measuring instrument 1 and the second laser measuring instrument 2 are connected up and down through a rotating connection shaft 3 , the first laser measuring instrument 1 includes a lower casing 11, the lower casing 11 is provided with a laser lower projection window 12 in front, and a first laser emitting head 13 is arranged behind the laser lower projection window 12, so The bottom of the lower housing 11 is provided with a power supply board 14, the second laser measuring instrument 2 includes an upper housing 21, and the upper housing 21 is provided with a laser upper projection window 22 in front of the upper laser projection window. 22, a second laser emitting head 23 is arranged behind, and a main control board 24 is arranged inside the upper housing 21, and the first laser emitt...

Embodiment 2

[0074] as attached Figure 11 As shown, the present embodiment provides a dual-beam measurement method, comprising the following steps:

[0075] A. Fix the double-beam laser measuring instrument at point A, the first laser measuring instrument measures the emitted laser signal to measure point B, and obtains the feedback signal data B' of point B by receiving the reflected laser signal at point B;

[0076] B. At the same time, after the second laser measuring instrument rotates the angle α, it obtains the rotation angle signal data α' through the internal gyroscope, and then emits a laser signal to point C, and obtains point C by receiving the laser signal emitted by point C Feedback signal data C';

[0077] C. The main control board calculates the acquired feedback signal data B' at point B, feedback signal data C' at point C, and angle signal data α' to obtain the specific BC' of the straight line between point B and point C. The calculation formula is as follows: BC'^2=B'...

Abstract

The invention relates to the technical field of optical range finding, and especially relates to a dual-beam laser measuring instrument and a dual-beam measuring method. The structure comprises a first laser measurer and a second laser measurer, wherein the first and second laser measurers are connected in an up / down direction through a rotating connection shaft. The measuring instrument and measuring method can achieve the measurement of the distance between two remote points, and solve a problem of direct measurement caused by the limiting of geographic conditions.

Description

technical field [0001] The invention relates to the technical field of optical distance measurement, in particular to a double-beam laser measuring instrument and a double-beam measuring method. Background technique [0002] Laser rangefinders have been widely used in: electric power, water conservancy, communication, environment, construction, geology, police, fire protection, blasting, navigation, railway, anti-terrorism / military, agriculture, forestry, real estate, leisure / outdoor sports and other fields, Laser ranging is the use of laser to measure the distance of the target accurately. When the laser rangefinder is working, it emits a very thin laser beam to the target, and the photoelectric element receives the laser beam reflected by the target. The timer measures the time from the launch to the reception of the laser beam, and calculates the distance from the laser rangefinder to the target. . [0003] The existing laser ranging in the market is based on the rangin...
