Problems solved by technology

However, the auxiliary measurement of the horizontal bubble can only be measured when the horizontal bubble is adjusted to the center state, so it is prone to problems such as slow debugging, easy vibration of the horizontal bubble, and cumbersome operation.
That is to say, the traditional laser rangefinder basically performs distance measurement and positioning after the laser rangefinder is basically horizontal or vertical by manual visual inspection, or performs measurement after calibration by other calibration devices. These operations are cumbersome and cause large The error makes the user experience relatively poor

Abstract

The invention discloses a laser positioning device, which comprises a distance measuring unit, an acceleration sensing unit and a control unit. Wherein the distance measuring unit measures the distance between the actual irradiation point of the laser positioning device in the target space to the horizontal direction and the distance to the actual irradiation point on the vertical direction respectively; the acceleration sensing unit measures the current acceleration direction of the laser positioning device; the control unit calculates an angle deviation between the current acceleration direction and the gravity direction of the distance measuring unit in the current direction, and calculates the positioning coordinates of the laser positioning device in the target space by using the measured distance to actual irradiation point on the horizontal direction and the distance to actual irradiation point on the vertical direction. By obtaining the accuracy compensation of the distance from the horizontal direction surface and / or the vertical distance to the vertical direction surface, the invention realizes the quick and accurate positioning of the target object in the target space, and improves the operational reliability and precision of the device.

Description

technical field [0001] The invention relates to the technical field of space positioning, in particular to a laser positioning device. Background technique [0002] As a distance measuring instrument, the laser rangefinder is mostly used in construction projects. The laser range finder in the prior art performs distance measurement through pulse or phase, which first measures two target points and then obtains the vertical distance between the two points on the measured object surface through a default fixed algorithm, and obtains the laser range finder and The vertical distance to the target surface can only be measured with visual aiming or with auxiliary accessories. However, the measurement accuracy of visual aiming is poor, which leads to inaccurate and convenient positioning measurement; and the auxiliary measurement process of accessories is more cumbersome, which makes the measurement not convenient and also increases the error in the measurement. [0003] In order...
