Embodiment Construction

[0014] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0015] figure 1 It is a structural schematic diagram of a laser measuring device for measuring the length and area of ​​a remote macroscopic object, including a test platform 1, a laser 2, a laser echo receiving system 3, a two-dimensional scanning galvanometer 4, and a computer 5.

[0016] The laser 2 and the two-dimensional scanning vibrating mirror 4 are installed on the test platform 1. The two-dimensional scanning vibrating mirror 4 is fixed in front of the output mirror of the laser 2 to receive and reflect the laser beam output by the laser 2. The two-dimensional scanning vibrating mirror 4 includes a mirror , the mirror can swing to change the propagation direction of the reflected laser beam.

Abstract

The invention discloses a laser measuring device for measuring the length and area of ​​a remote macroscopic object, which comprises a test platform, a laser, a laser echo receiving system, a two-dimensional scanning vibrating mirror and a computer. The laser measuring device for measuring the length and area of ​​a remote macroscopic object provided by the invention can realize the remote measurement of building height, land circumference and area as required. The device is easy to carry, easy to operate, and has high measurement accuracy, which overcomes the shortcomings of traditional land area measurement and building measurement, such as numerous measurement equipment, cumbersome measurement procedures, and error-prone, and has broad application prospects.

Description

technical field [0001] The invention relates to a laser measuring device, in particular to a laser measuring device for measuring the length and area of ​​a remote macroscopic object. Background technique [0002] In fields such as construction and land planning, it is often necessary to measure land dimensions, land areas, and building heights. At present, some building heights are measured directly with tools, and some are measured indirectly with optical principles; in the measurement of land size and area, the plot is usually regarded as a closed space composed of irregular polygons, and each corner is located. Point plane coordinates are used to indirectly calculate the plot area, and some special soil area measuring instruments are also used. Usually, the measurement of building height and land area requires the use of different measurement tools, and most of them are indirect measurements. First, use the length tool to measure the length, and then calculate the measu...
