Problems solved by technology

The system modeling method is an important method to calculate the amount of construction demolition waste. However, the prerequisite for using the system modeling method to calculate the construction demolition waste is to have the BIM model of the building. In the process of large-scale urban renewal, A large number of buildings to be demolished do not have existing BIM models

Abstract

The invention relates to the technical field of intelligent buildings, and discloses a method and device for predicting yield of building demolition waste. The method comprises the steps: collecting point cloud data of a building, wherein the point cloud data comprises the spatial information of the building; preprocessing the point cloud data; classifying the preprocessed point cloud data througha classifier, and reversely generating a BIM model from the classified point cloud data; calculating the building area of the building according to the BIM model; calculating the waste output of thebuilding according to the building area; and through a reverse modeling technology, predicting the existing building demolition waste generation amount, 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 generation of construction demolition waste. Background technique [0002] At present, the large-scale demolition and reconstruction of existing urban areas has become an important means of urban renewal. The construction demolition waste generated in the process of urban renewal is the main source of construction waste in my country. Predicting the generation of construction demolition waste has become an One of the important steps to smart demolition and increase the speed of urban renewal. The system modeling method is an important method to calculate the amount of construction demolition waste. However, the prerequisite for using the system modeling method to calculate the construction demolition waste is to have the BIM model of the building. In the process of large-scale urban renewal, A large number of buildings to be de...
