摘要
在点光源小扰动环境下,传统的室内空间布局设计方法不能适应不同时间段、不同天气特性下的光强度动态变化,影响居住环境的舒适性。设计了一种改进的点光源小扰动环境室内空间布局优化方法,利用单自由曲面的折光能力实现光线准直出射,构建固定目标面均匀照明微分方程,采用切面迭代法求解单个自由曲面上的点坐标,通过Harris角点检测算法检测出每帧图像中的角点位置,然后对这些角点采用LK光流法进行跟踪,采用周期图法估计局部灯光照射光强,基于数学形态学的分割方法对平移进行特征分割,通过向量相交法得到室内亮点模型的纹理特征,实现室内建筑空间优化设计。实验结果表明,采用该设计方法,能适应不同时间段、不同天气特性下的光强度动态变化,提高居住环境的舒适性。
The point light small disturbance environment, indoor space layout of the traditional design method cannot adapt to the dynamic changes of light intensity of different time, different characteristics under the influence of the weather, the living environment of comfort. An improved point source of perturbation method of layout optimization of indoor environment space is designed, realization of collimating light emitted by a single free surface refractive power, building a fixed target uniform illumination differential equation, using the coordinate free surface of single section iterative method for solving the point, through the Harris corner detection algorithm to detect corners of each in the picture, and then to track these corner points using LK optical flow method, using the periodogram local light irradiation intensity, segmentation method based on mathematical morphology to translate feature segmentation, texture features obtained by indoor highlight model vector intersection method, realizes the indoor architectural space optimization design. The experimental results show that, by using this design method, can adapt to the dynamic changes of light intensity of different time, different weather characteristics, improve the living environment of comfort.
