Embodiment approach

[0024] The invention proposes a laser scanner-based method for monitoring the appearance of earthwork filling and excavation in hydropower projects, which is used to monitor the three-dimensional appearance of the working face and provide construction information feedback during backfilling and excavation construction operations. The method includes the following steps.

[0025] ① During the construction process, use a 3D laser scanner to perform 3D laser scanning on the filling and excavation face to obtain the 3D point cloud data of the filling and excavation face;

[0026] ②Using point cloud data based on reverse modeling technology to realize 3D modeling and real scene replication of filling and excavation working face;

[0027] ③ Perform 3D analysis on the 3D model information of the filling and excavation face to obtain the information of the filling and excavation appearance;

[0028] ④ On the basis of filling and excavation appearance information, further feedback anal...

Abstract

The invention discloses a water-power engineering earthwork filling-digging feature monitoring method based on a laser scanner. The water-power engineering earthwork filling-digging feature monitoring method is used for monitoring working face three-dimensional features and providing construction information feedback in the filling-digging construction operation process; and the water-power engineering earthwork filling-digging feature monitoring method comprises the following steps that (1) the three-dimensional laser scanner is used in the construction process for conducting three-dimensional laser scanning on filling-digging working faces, and three-dimensional point cloud data of the filling-digging working faces are obtained; (2) the point cloud data are used for achieving three-dimensional modeling and actual scenery copying on the filling-digging working faces based on a reverse modeling technology; (3) three-dimensional analysis is carried out on three-dimensional model information of the filling-digging working faces to obtain filling-digging feature information; (4) filling-digging feedback information obtained through analysis is further fed back on the basis of the filling-digging feature information; and (5) the filling-digging feedback information is sent to a construction site, and feedback control over the filling-digging construction operation is carried out. By means of the method, the technical problems in site construction operation like accurate three-dimensional modeling, filling feature information three-dimensional analysis of water-power engineering filling-digging operation are solved.

Description

technical field [0001] The invention relates to the field of monitoring the appearance of earthwork filling and excavation in hydropower projects, and more specifically, relates to a method for monitoring the appearance of earthwork filling and excavation in hydropower projects based on a laser scanner. Background technique [0002] At present, the construction process of water conservancy and hydropower projects involves a large number of backfilling and excavation construction operations, but there is no mature method to realize the digital construction of filling and excavation operations. [0003] The Chinese patent number is: CN200710172146.4 discloses a real-time detection method for foundation pit excavation, which is used to detect the displacement change of the soil around the pit, the change of the soil pressure around the pit and the uplift of the soil at the bottom of the pit during the excavation of the foundation pit. However, this method is mainly aimed at the...
