Unmanned aerial vehicle inspection data checking method based on three-dimensional model

Abstract

The invention relates to the technical field of unmanned aerial vehicle inspection, in particular to an unmanned aerial vehicle inspection data checking method based on a three-dimensional model, and the method comprises the following steps: 1, carrying out the automatic three-dimensional reconstruction of shot building inspection data at a background; 2, logging in background software to open a corresponding building three-dimensional model; 3, after the building model is opened, clicking a building part to be checked, and popping up a live-action picture; 4, enabling the user to zoom and move the real scene picture or the three-dimensional model; and 5, after a background user finds the building disease, acquiring the specific position of the disease through comparison of the live-action picture and the model. Manpower participation is greatly reduced through the full-automatic photographing function of the unmanned aerial vehicle, the workload of people is relieved, and the labor cost is reduced. With automatic marking and GPS positioning functions of the unmanned aerial vehicle, the shot picture and the position are located and associated, so that the time of later manual comparison is greatly shortened, and the accuracy of the disease position is improved.

Problems solved by technology

[0002] In recent years, with the rapid development of computer science and technology and the improvement of digital informatization, in the process of engineering design, people's needs are not limited to the traditional two-dimensional graphic design drawings in hand, but more inclined to obtain clearer The delivery method is intuitive and includes detailed design models. This method can make the later procurement investment, construction and maintenance management more convenient and fast. The 3D modeling technology of large bridges is an important design tool that has developed quite successfully in the current computer-aided design technology. The effective application of 3D real scene modeling technology greatly shortens the design cycle required in the initial stage of project construction, and also improves the design quality and efficiency, liberating manpower and material resources to the greatest extent, but this also requires a large number of related buildings to be inspected

[0003] At present, the traditional way of viewing building inspection data is to first screen by machine and then manually compare. This method has high requirements for relevant personnel, and requires them to associate all the found diseases with the location of the building one by one, which is difficult. Achieve all-round coverage without omissions. In addition, when personnel view massive inspection data, they need to use tags to restore the site. The entire data viewing process is cumbersome and boring, time-consuming, high labor costs, and low efficiency.
