Problems solved by technology

[0002] At present, the actual measurement tools on the market are low in technology content, and the labor cost required to use traditional tools for measurement remains high; for the measuring instruments currently on the market, because they do not have the function of angle measurement, they must be exchanged many times during the measurement process. Laser line markers and laser rangefinders are prone to human error, resulting in the final splicing and installation of the structure not meeting the design requirements, and must be re-constructed, resulting in material loss, increased capital waste, and delays in the construction period

Embodiment 1

[0044] Embodiment 1: In this implementation, it is the specific content of the algorithm used in the ranging method of a laser rangefinder for house measurement;

[0045] (1) Laser ranging algorithm:

[0046] Laser distance measurement is a method of distance measurement in light wave distance measurement. If light travels in the air at speed c and takes time t to go back and forth between two points A and B, then the distance L between points A and B can be used as follows Means: L=ct / 2;

[0047] (2) Pythagorean measurement method:

[0048]The Pythagorean measurement condition is: a known right triangle, measure the hypotenuse length l and the included angle θ, and then calculate the length of the other side of the included angle through the Pythagorean theorem and trigonometric functions: D=l sinθ;

[0049] (3) Kalman filter algorithm in the data processing process:

[0050] The Kalman filter algorithm uses the process model of the system to predict the next state of the ...

Abstract

The invention discloses a laser rangefinder for house measurement, and a method thereof. In the invention, a main control board controls the operation of an angle measurement module and a laser measurement module, the angle measurement module and the laser measurement module transmit data information to the main control board, and the main control board displays the measured data information through a touch display screen; a measurement key is used to control the single measurement of the angle measurement module and the laser measurement module; and an operation key is used to set parametersand view data. The invention can measure the distance from the measurement point to the target point and the tilt angle by using the laser rangefinder, further realizes the measurement of the range ofthe top plate and the range of the ground, has two measurement methods of angle measurement and distance measurement, and has prominent functions in improving measurement calculation accuracy, reducing errors and the like by using laser ranging and pythagorean measurement methods, measurement and calculation methods of the range of the top plate and the range of the ground, and Kalman filter dataprocessing methods.

Description

technical field [0001] The invention belongs to the technical field of building equipment, and in particular relates to a laser rangefinder for building measurement and a method thereof. Background technique [0002] At present, the actual measurement tools on the market are low in technology content, and the labor cost required for measurement with traditional tools remains high; for the measuring instruments currently on the market, because they do not have the function of angle measurement, they must be exchanged many times during the measurement process Laser line markers and laser range finders are prone to human errors, resulting in the final spliced ​​and installed structure not meeting the design requirements, and must be re-constructed, resulting in material loss, increased capital waste, and delays in the construction period. Contents of the invention [0003] The purpose of the present invention is to provide a laser range finder and its method for house measure...
