Embodiment Construction

[0043] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be pointed out that the following embodiments are intended to facilitate the understanding of the present invention, but do not have any limiting effect on it.

[0044] An indoor pipeline position recording and projection method is mainly divided into two parts: a smartphone terminal recording of a home pipeline position and a real size projection of a certain area on a wall.

[0045] like figure 1 As shown, the steps to record the location of the home pipeline on the smartphone are as follows:

[0046] After the laying of the household pipelines and before the laying of the exterior walls, a picture of the pipelines was taken with the smartphone software, and the captured pipeline images were corrected for perspective distortion, and then collaged and merged to ensure that the size ratio of the drawings and photos was correct.

Abstract

The invention discloses an indoor pipeline position recording and projection method, comprising: (1) taking a plurality of wall pipeline pictures with a mobile phone, and performing distortion correction; (2) splicing and merging the corrected pipeline pictures to obtain a record The wall picture of the complete pipeline position; (3) Place the projection device in the area in front of the corresponding wall of the pipeline; (4) Connect the mobile phone and the projection device, and measure the spatial coordinate system between the projection device and the corresponding wall; (5) Turn on the projection , the projection frame A appears on the wall, the coordinate points of the projection frame A are measured, and the corresponding projection area A' is identified in the wall picture on the mobile phone, and the focal length is adjusted to complete the real-size projection; Adjust the end to the target projection area B', and then locate the coordinates of the projection area B'; adjust the position of the projection lens to project corresponding to the position of the wall. The invention has simple operation and low learning cost, and can visually display the position of the internal pipeline on the wall.

Description

technical field [0001] The invention relates to the technical field of building decoration, in particular to an indoor pipeline position recording and projection method. Background technique [0002] When renovating a home or renovating an old house, it is unavoidable to transform and construct the wall. If the location of the water pipes, wires and other pipelines in the wall is wrongly positioned, it will affect the construction and even cause accidents and losses. Therefore, the recording of the position of the pipeline after the installation of the pipeline will help the later construction to accurately locate the pipeline layout in the wall, which will be of great help to the construction quality and efficiency, and can also effectively prevent accidents. [0003] At present, in the construction industry, when obtaining the location and layout of the pipelines in the house before the wall demolition and modification, the calculation is generally based on the constructio...
