Linear positioning device and method

Abstract

The invention provides a linear positioning device. The linear positioning device comprises an enclosure as well as a bubble level gauge, an electronic level gauge, and first to third laser parts, and further comprises a computing control module capable of automatically calculating friction, in the total length of a horizontal line segment, of length of a line segment measured by the first laser part or the second laser part, and an information recording module capable of recording fixed fraction, wherein a first laser line and a second laser line are on the same straight line, and are opposite in direction; the first laser line and the second laser line are emitted back to back, and are kept to horizontally emit laser under display guide of the level gauges and under regulating operation of a user; a third laser line is perpendicular to the second laser line and the first laser line, and the third laser line is downwards emitted vertically. The linear positioning device realizes quick and accurate automatic positioning for certain fraction target point on the horizontal line segment, can correspondingly mark out a projection point, on ground, of the certain fraction target point, and further can quickly and accurately locate a target point in a two-dimensional coordinate.

Description

technical field [0001] The invention belongs to the field of laser ranging, and in particular relates to a linear positioning device and method. Background technique [0002] When precise positioning is required for equipment installation and other situations, it is often necessary to use linear measurement tools such as total stations or laser range finders. A spirit level is included in a total station or laser range finder to ensure that the laser line generated in the instrument is emitted level. However, when using linear measuring tools such as total stations or laser rangefinders for positioning, it is necessary to use the ruler at the other end to continuously move and adjust to determine, which takes a long time. If you use a hand-held laser rangefinder or other measuring tools, because the hand-held laser rangefinder is generally not equipped with a leveler, there may be large errors due to uneven ground and human factors, making it difficult to accurately locate....
