Abstract

The embodiment of the invention discloses a method and device for determining the measurement position of a virtual guiding rule and a storage medium. The method comprises the following steps: acquiring point cloud data of a measured wall surface, and judging the attribute of the measured wall surface based on the point cloud data of the measured wall surface; determining at least one target wall surface on the measured wall surface based on the attribute of the measured wall surface; and determining a measurement position of the virtual guiding rule on the target wall surface based on the point cloud data of the target wall surface and a guiding rule placement rule. According to the embodiment of the invention, the attribute of the measured wall surface is determined through the point cloud data of the measured wall surface, and the measurement position of the virtual guiding rule on the target wall surface is determined according to the point cloud data of the target wall surface and the guiding rule placement rule, so that the problem of unreasonable position setting of the virtual guiding rule caused by different wall surface types is solved; and the accuracy of a subsequent perpendicularity measurement result is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of building construction, and in particular to a method, device and storage medium for determining a measurement position of a virtual ruler. Background technique [0002] The actual measurement of the verticality of the wall is an important content of the quality control of the wall in the construction field. The current method of actual measurement of the verticality is mainly that the construction personnel use a 2-meter ruler to manually measure the wall. However, with the increasingly serious labor shortage in construction jobs, the average age of the labor force is increasing year by year. In this context, using advanced technology to improve the degree of automation in the field of construction and reduce labor demand has become a new development trend. [0003] In recent years, non-contact verticality measurement methods have been developed. The non-contact verticality measure...
