Indoor modeling method and device and terminal equipment

Abstract

The invention is suitable for the technical field of data processing, and provides an indoor modeling method and device, and terminal equipment, and the method comprises the steps: calculating a normal vector included angle between adjacent point clouds in ceiling point clouds; determining the ceiling point clouds with the normal vector included angles greater than a preset included angle threshold as boundary point clouds; and determining the ceiling boundary according to the boundary point cloud. According to the method, the problems that in an existing indoor modeling method, when a non-orthogonal structure occurs and a ceiling boundary is constructed, a curve is easily replaced with a straight, so that the ceiling boundary deviation is large, or priori knowledge needs to be manually provided for auxiliary modeling, and the modeling efficiency is low can be solved. 本申请适用于数据处理技术领域，提供了一种室内建模方法、装置及终端设备，所述方法包括：计算天花板点云中相邻点云之间的法向量夹角；将法向量夹角大于预设夹角阈值的天花板点云确定为边界点云；根据所述边界点云确定天花板边界。本申请可以解决现有的室内建模方法中，当出现非正交结构，构建天花板边界时，容易以直代曲，导致天花板边界偏差大，或者，需要人为提供先验知识进行辅助建模，建模效率低下的问题。
