Embodiment 1

[0019] This embodiment provides a method for checking the position of embedded parts based on HDS7000 three-dimensional scanner technology, such as figure 1 and figure 2 As shown, the origin of the construction coordinate system is the intersection point between the ground and the two side walls, the A axis is parallel to the intersection line between the ground and the wall, the B axis is perpendicular to the A axis on the ground, and the H axis is upward, which conforms to the right-handed coordinate system. The plane formed by the X-axis and the Y-axis of the scanner coordinate system is parallel to the ground and conforms to the right-handed coordinate system, including the following steps:

[0020] The first step is to mark the center points of six embedded parts on the wall, roof and ground of the room with black and white paint;

[0021] In the second step, select three control reference points 1, 2, and 3 at the center points of the six embedded parts, and the coordi...

Abstract

The invention relates to a three-dimensional scanner technology-based embedded part position detection method. The method comprises steps: all embedded part central points are marked, three or more than three control reference points are selected from the embedded part central points, coordinates of the control reference points in a construction coordinate system are measured, a scanner is erected, positions with the embedded part central points are scanned, data of the scanner are read, numbers of the embedded part central points are marked according to the scanned data, a file is used for outputting coordinates of each point of the embedded part central points, the scanned data are converted into the construction coordinate system through the control reference points, and coordinate values of the embedded part central points in the construction coordinate system are obtained. According to the method of the invention, an accurate detection result can be obtained, a basis can be provided for detection and acceptance of a nuclear power construction wall and a bottom plate embedded part, the difficult problem of detecting positions of embedded parts, especially when the number of embedded parts is large, in the case of nuclear power construction can be solved, safety of detecting an overhead embedded part is improved, the detection is flexible, and field construction quality control requirements can be met.

Description

technical field [0001] The invention relates to a method for checking the position of embedded parts based on three-dimensional scanner technology, belonging to the technical field of nuclear power plant construction. Background technique [0002] There are many equipment and pipelines in nuclear power plants, and there are many embedded parts reserved for walls and floors. During the construction process, inspections are frequent and measurements are many. The walls are high and the construction site conditions are poor. Inspections are inconvenient, safety performance is not easy to guarantee, and inspections take a long time. , It is not conducive to the optimization of the construction period and cannot ensure the quality of work. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art, and propose a method for inspecting the position of embedded parts based on three-dimensional sca...
