Abstract

The invention relates to an intelligent lofting construction method based on an unmanned aerial vehicle inclined image technology. The intelligent lofting construction method comprises the following steps of (1) determining an engineering construction red line range; (2) planning an aerial survey area of the unmanned aerial vehicle and optimizing a flight path to obliquely shoot a live-action picture of a construction site through aerial survey; (3) importing the shot live-action picture of the construction site into three-dimensional modeling software to generate a site model; (4) importing the generated site model into BIM modeling software for building modeling; (5) picking up point position coordinates and elevation parameters of the model component, and importing the point position coordinates and the elevation parameters into a holographic projector to realize accurate lofting; or (6) picking up the coordinates and elevation parameters of the model component, and importing the coordinates and elevation parameters into the BIM measurement robot to realize accurate lofting. Engineering construction quality and the operation precision are improved. Acquisition of a large amountof repeated measurement data is avoided, interference errors caused by human factors are reduced, and engineering construction quality and operation precision are improved.

Description

Technical field: [0001] The present invention relates to the field of three-dimensional modeling of UAV and the field of engineering survey and stakeout, and more specifically, relates to an intelligent stakeout construction method based on the oblique image technology of the drone. Background technique: [0002] The quality control of engineering construction depends on accurate construction measurement and stakeout. The traditional construction stakeout method is based on the drawings and site conditions, using a general total station for construction stakeout. The traditional engineering survey and stakeout is mainly divided into the following steps: measurement and release of the plane control network; vertical measurement of the plane control network; height transfer. [0003] However, there are certain difficulties and problems in the traditional engineering surveying and setting out: (1) The workload is large and the precision is high; (2) There are many types of work...
