Problems solved by technology

[0005] However, there are the following problems in using manual measurement and measurement: (1) Due to the limitation of operating efficiency, manual data collection can only be performed on some points of measurement, and the sampling rate is low; (2) Most operators only measure by feeling The flatness of the wall surface is not strictly combined with a wedge-shaped feeler gauge, resulting in low measurement accuracy; (3) In the entire measurement stage, the measurement workload of the wall flatness is the largest, and the measurement is the most cumbersome. High time and labor costs

Abstract

The embodiment of the invention discloses a wall surface virtual guiding rule detection method, system and device and a storage medium. The method comprises the following steps: acquiring initial point cloud data containing a to-be-measured wall surface; extracting target point cloud data corresponding to the to-be-detected wall surface from the initial point cloud data; determining a guiding ruleendpoint position of a virtual guiding rule in the to-be-measured wall surface according to a preset measurement range and a preset measurement angle of wall surface measurement, and determining a guiding rule measurement position in the to-be-measured wall surface according to the guiding rule endpoint position; and in the guiding rule measurement position range, adjusting the pose of the virtual guiding rule based on the target point cloud data, and determining the target pose of the virtual guiding rule. According to the technical scheme, the guiding rule pose in wall surface measurement is determined more efficiently and accurately, so that the wall surface measurement precision is improved, and the time cost and the labor cost in actual measurement are reduced.

Description

technical field [0001] This application claims priority based on Chinese patent 201911135048.2 filed domestically on November 19, 2019, the disclosure of which is incorporated herein by reference. [0002] The embodiments of the present invention relate to a construction engineering construction detection technology, and in particular, to a method, system, equipment and storage medium for detecting a virtual ruler on a wall. Background technique [0003] In the construction phase of the construction project, the actual measurement and quantity are tested on the entities on the construction site, and the quality status of the product is timely fed back, so that the project manager can improve the construction process in a timely manner. [0004] At present, the actual measurement still uses the relatively old data collection method. For example, the measurement of the flatness of the wall is measured by the actual measurement personnel using a 2-meter ruler. [0005] However...
