Problems solved by technology

[0002] The erection of iron towers, erection of conductors, and installation of accessories in power transmission and transformation projects are all carried out at high altitudes. In the acceptance process of power transmission and transformation projects at this stage, the acceptance of owners and supervisors basically relies on high-altitude inspections by climbing personnel. Traditional power transmission and transformation projects The acceptance operation is too dependent on the experience and operation level of the personnel, the inspection process is cumbersome, the measurement accuracy is difficult to control, and the measurement results cannot be reused. Risks, prone to personal injury and death accidents such as falling, for the low efficiency and accuracy of the existing transmission line completion acceptance method, no effective solution has been proposed so far

Abstract

The invention relates to the technical field of power transmission and transformation project acceptance, in particular to a power transmission and transformation project acceptance method based on BIM and point cloud measurement. The method comprises the following steps: S1, building a BIM model with a design drawing as an information source, wherein the BIM model comprises standard parameters of key parts of a power transmission and transformation project; S2, acquiring point cloud data, and constructing a point cloud data model according to the point cloud data, wherein the point cloud data model comprises actual parameters of the key parts of the power transmission and transformation project; S3, comparing the BIM model with the point cloud data model to obtain construction acceptance data; and S4, visualizing the construction acceptance data, outputting an acceptance report, and completing the acceptance of the power transmission and transformation project. According to the power transmission and transformation project acceptance method based on the autonomous flight of unmanned aerial vehicles and three-dimensional laser point cloud, the BIM model and the point cloud data model are compared and analyzed, and rapid and efficient acceptance of the power transmission and transformation project is achieved.
