Abstract

The invention is applicable to the technical field of point cloud scanning, and provides a construction management method and device based on point cloud scanning, and the method comprises the steps of obtaining the point cloud data obtained by laser scanning of an unmanned aerial vehicle on a construction site; preprocessing the point cloud data and then establishing a point cloud model of a construction site; fitting the point cloud model and the construction BIM model to obtain a fitting model; and generating a deviation report according to the deviation between the point cloud model and the construction BIM in the fitting model. According to the embodiment of the invention, the problems of low manual on-site data measurement precision, low efficiency and a lot of manpower consumption in the prior art are solved; the abnormal construction place in the construction site can be found rapidly, the measurement precision is high, and the method and the device do not need the participation of manpower, improve the construction supervision efficiency, enable the supervision analysis to be more accurate, and improve the management quality and the project management efficiency.

Description

technical field [0001] The invention belongs to the technical field of point cloud scanning, and in particular relates to a construction management method and device based on point cloud scanning. Background technique [0002] At present, the application of BIM model in the construction industry has been very extensive. By establishing BIM model before construction, it can be effectively applied to project planning, collaborative design, collision inspection, performance analysis, construction simulation, cost and schedule control of the whole life cycle of construction projects. etc. Although there is a very detailed BIM model as a construction reference, in the actual building construction process, due to a large number of human participation and mechanical errors, the problem of construction errors is often encountered. The traditional construction supervision is based on relevant supervision personnel. The quality acceptance specification uses measurement tools to obtai...
