Problems solved by technology

Existing predictions on the amount of construction demolition waste generated based on laser scanning mainly rely on manual on-site surveys to collect construction information about buildings to be demolished on site, such as height and area. This relatively primitive data collection method requires a lot of time. Time, manpower and material resources, the error is also large

Abstract

The invention relates to the technical field of intelligent buildings, and discloses a building demolition waste output prediction method and device based on laser scanning. The building demolition waste output prediction method comprises the steps: collecting the point cloud data of a building through a three-dimensional laser scanner; processing the point cloud data to obtain a spatial topological relation of the point cloud data; restoring a three-dimensional model of the building through the spatial topological relation; calculating the building area of the building according to the three-dimensional model; calculating the waste output of the building according to the building area; and predicting the existing building demolition waste yield through the three-dimensional laser scanningtechnology, thus facilitating intelligent demolition.

Description

technical field [0001] The invention relates to the technical field of intelligent buildings, in particular to a method and device for predicting the amount of construction demolition waste generated based on laser scanning. Background technique [0002] At present, the large-scale demolition and reconstruction of existing urban areas has become an important means of urban renewal. In the process of urban renewal, a huge amount of construction demolition waste will be generated. Construction demolition waste specifically refers to the solid waste generated during the demolition process of buildings. , including waste concrete blocks, brick blocks, scrap metal, scrap wood, and other waste. Construction demolition waste is the main source of construction waste in my country (including solid waste generated in the process of building new construction, reconstruction, expansion and demolition), accounting for 70-75% of the total. The amount of construction demolition waste gene...
