The invention discloses a substation engineering steel structure installation intelligent acceptance method based on oblique photography. The method comprises the following steps: modeling a steel structure connection part in a target area power transmission and transformation project by using unmanned aerial vehicle flight to obtain a flight oblique photography model; constructing a BIM model corresponding to the flight oblique photography model, and after the two models are overlapped, selecting a three-dimensional space detection range and extracting three-dimensional model space data features in the range; and calculating attribute deviations of the welding points and the screws in the BIM model and the industrial standard process model, and judging that the welding points and the screws in the BIM model do not conform to the process standard and have the phenomena of looseness, corrosion and the like when screening out that all the attribute deviations are greater than a set threshold value. The problem of installation quality acceptance of the high-altitude part of the steel structure can be effectively solved, three-dimensional modeling is conducted on the high-altitude steel structure through the unmanned aerial vehicle aerial survey technology, the construction quality of the steel structure is intelligently analyzed, the phenomena of bolt loosening, welding opening corrosion and the like are intelligently positioned, and intelligent acceptance of steel structure construction can be achieved.
Description
Technical field [0001] The present invention relates to the field of construction of electric construction steel structures, and more particularly to mounting intelligent acceptance methods for mounting of substation engineering steel structures based on slope photography. Background technique [0002] During the construction of transmission and electrical construction, steel structure construction is the most important part of the construction of the entire project. The steel structure has high risk, complex structure, and the steel structure is completed, which belongs to the hidden project, so steel structure construction quality Acceptance is critical to the entire project, related to safety issues in post construction and operation. At present, the method taken by power company in the acceptance of steel structural acceptance in power generation engineering is mainly based on two-dimensional form, mainly by drawing inspection, material entry control and process training, and...
