Wall sag detection method and device

Abstract

The invention discloses a method and a device for detecting verticality of a wall body and belongs to the technical field of measuring tools. The method comprises the steps: acquiring a pitch deviation angle and a vertical deviation angle of a terminal in real time, wherein the pitch deviation angle is an included angle between a plane, where a screen of the terminal is located, and the vertical direction, the vertical deviation angle is an included angle between a vertical side edge of the terminal and the vertical direction, and the vertical side edge is attached to the surface of the wall body to be detected; detecting whether the terminal is in a relative stable state or not at the same this moment when the acquired pitch deviation angle is smaller than a preset angle threshold value; locking the vertical deviation angle acquired at the same moment when the terminal is in the relative stable state, and outputting the vertical deviation angle. According to the method and the device, the technical problem in related technologies that the measurement error of the vertical deviation angle is relatively large due to position errors when the terminal is placed vertically is solved, and the technical effect of improving accuracy of measurement results is achieved.

Description

technical field [0001] The invention relates to the technical field of measuring tools, in particular to a wall sag detection method and device. Background technique [0002] In the construction site, in order to judge whether the sag of the wall meets the standard, construction personnel usually need to measure the sag of the wall. [0003] When measuring the sag of the wall, the construction personnel will place the equipped ruler vertically close to the wall to be measured. The single-axis angle sensor in the ruler can measure the angle between the ruler and the direction of gravity, and output the measurement value. [0004] Since this kind of ruler is usually only provided with a single-axis angle sensor for measuring the angle between the ruler and the direction of gravity, it is required that the ruler must be placed vertically when measuring, and the construction personnel will vertically place the ruler There is usually a large deviation during placement, which le...
