Embodiment Construction

[0032] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .

[0033] Such as figure 1 As shown, the scanning method based on the 3D laser detection system to obtain the housing index parameters includes:

[0034] Step S1: Set up the site at an appropriate location in the house, and set up the scanner flatly on the fixed tripod of the site;

[0035] The 3D laser scanner site can be set at a high place around the building or a place with a wide view. Fix the tripod on the site. After fixing the 3D laser scanner on the tripod, adjust the bolts on the tripod to scan the 3D laser scanner. The instrument is firmly on the base of the tripod.

[0036] Since most 3D laser scanners have built-in angle compensation, thro...

Abstract

The invention discloses a scanning method for obtaining house index parameters based on a three-dimensional laser detection system. The scanning method comprises setting up a site at an appropriate position of the house; arranging a scanner leveling on a fixing foot of the site; placing reflection targets around the scanner, and adjusting the target center position of each reflection target so asto make the reflection targets parallel to the optical axis of the scanner; starting the scanner to scan the house structure after the scanning parameters of the scanner are initialized; collecting elevation coordinate of each reflection target; performing site splicing through the elevation coordinates of multiple reflection targets; converting the coordinate system of the scanner into a matchedengineering coordinate system and forming point cloud data therein; performing identification on house members, and marking the positions and the identification results of the identified house membersin the point cloud data; and importing a plane figure of the house generated in CAD to obtain the geometric parameters of the overall index of the house. According to the scanning method for obtaining the house index parameters based on the three-dimensional laser detection system, the manual measurement mode is replaced by the three-dimensional laser scanning detection system, so that the detection efficiency and the detection precision are improved.

Description

technical field [0001] The invention relates to the technical field of structural identification, in particular to a scanning method for acquiring building index parameters based on a three-dimensional laser detection system. Background technique [0002] At present, in the structural appraisal, it is necessary to collect the survey report of the building, the relevant data of construction and completion acceptance; when the data are incomplete, supplementary actual measurement should be carried out according to the appraisal needs. When inspecting the condition of the building structure on site, use a hand-held laser range finder and a steel tape to measure the size of the main grid, the net height of each floor and the cross-sectional size of the components. [0003] However, the existing measurement methods have the following defects: [0004] (1) Manual measurement work is repeated and has large errors, and the post-processing of data is cumbersome and inefficient, whic...
