Multifunctional laser ruler

Abstract

The invention relates to a multifunctional laser ruler. The laser ruler comprises a projection part and an imaging part, wherein the projection part comprises a laser projection component fixed on a base, the laser projection component is driven by a projection motor and rotationally connected with the base, the rotation angle of the laser projection component is measured by an angle measuring tool, the laser projection component and the angle measuring tool are electrically connected with a control block I installed in the base, the imaging part comprises a fixing frame, a photosensor and a control block II are installed on the fixing frame, and the control block II is wirelessly connected with the control block I. The laser ruler has the beneficial effects that distance measurement in awide range is realized through the same ruler, the measurement mode is simple, and the error is small.

Description

technical field [0001] The invention relates to the field of intelligent measuring equipment, in particular to a multifunctional laser ruler. Background technique [0002] In the existing distance measurement technology, there are great differences in the measurement methods according to the measurement length. For example, conventional distance measurement can be completed with common measurement tools such as rulers and tapes. For unconventional measurement of ultra-long distances, sonar and other measurement methods can be used. [0003] In constant-distance measurement and medium-to-long-distance measurement, the same measurement equipment cannot be used for unified measurement. If the constant-distance measurement method is used to measure medium-to-long distances, there will be a problem of insufficient measurement length. In constant-distance measurement, because the variable value collected by it is too small, it will cause large error and cannot be unified. For ex...

[0003] In constant-distance measurement and medium-to-long-distance measurement, the same measurement equipment cannot be used for unified measurement. If the constant-distance measurement method is used to measure medium-to-long distances, there will be a problem of insufficient measurement length. In the constant-distance measurement, the variable value collected by it is too small to cause a large error, so it cannot be unified
