Abstract

The invention provides a high-precision self-adaptive three-dimensional real-time visual piling early warning method and device and application. The method comprises the steps of obtaining terrain point cloud data and design pile parameters of a piling area; piling at a preset piling position according to the designed pile parameters; drawing a three-dimensional topographic map according to the topographic point cloud data; calculating engineering coordinates of the intersection point of the pile center line and the designed elevation surface; according to the three-dimensional real-time position of the actual pile body in the space, building a three-dimensional space parameter equation of the actual pile body, obtaining a distance function between the actual pile body and the designed pile body, solving the distance function, and obtaining the minimum distance between the actual pile body and the designed pile body and the pile body positions of the actual pile body and the designed pile body; and judging whether the minimum distance between the actual pile body and the designed pile body exceeds a threshold range or not, and if so, carrying out early warning. According to the invention, the three-dimensional space position of the pile in a seabed supporting layer, a seawater surface and other piles is monitored and early warned in real time, and the piling precision, reliability and efficiency are improved.

Description

technical field [0001] The present disclosure relates to the field of construction engineering, in particular to a high-precision self-adaptive three-dimensional real-time visualized piling warning method, device and application. Background technique [0002] At present, my country's infrastructure construction is developing rapidly, the scale of engineering construction is getting larger and larger, and the requirements for precision, reliability and efficiency are getting higher and higher. Pile is an important foundation of engineering construction, and the accuracy of piling directly affects the quality of subsequent engineering construction. Compared with land piling, offshore piling is more susceptible to environmental influences, such as wind speed, water surface fluctuations, and seabed sediment friction. Therefore, it is a necessary process to ensure the quality of the project to provide the three-dimensional space position of the pile on the sea surface and the be...
