基于多频段红外成像的多视角建筑布局规划研究

Research on the layout planning of multi-angle architecture based on multi-band infrared imaging

建筑规划布局探测过程容易发生墙体图像偏移,导致建筑布局成像效果不佳,为此,基于多频段红外成像技术研究多视角建筑布局规划问题。描述了多频段红外成像过程,利用该成像技术,选取三个单视角计算图像区域像素值,整合获取多视角建筑图像。采用Radon变换检测图像直线,形成图像平面,检测建筑布局图像距离位置和方位位置,完成建筑墙体图像偏移补偿。对补偿后的红外建筑布局图像进行归一化处理,计算图像像素值,并遍历三幅图像的所有像素点获取融合像素值。在此基础上,分割图像边缘特征点并灰度化处理图像,完成建筑规划布局建模。实验测试结果表明,本方法的建筑布局成像效果好,图像空间偏移量计算精度始终在80%以上,图像复原度较高,且与实测数值接近,整体性能较好。

Wall image migration is easy to occur in the process of building layout detection,which leads to poor imaging effect of building layout. Therefore,multi-frequency infrared imaging technology is used to study multi-angle building layout planning. This paper describes the multi-band infrared imaging process. Using this imaging technique,three single-view images are selected to calculate the image region pixel value,and the multi-view image is integrated.Radon transform is used to detect the straight line of the image,to form the image plane,to detect the distance position and azimuth position of the building layout image,and to complete the offset compensation of the building wall image.After the compensation,the infrared building layout image is normalized,the image pixel value is calculated,and traversed all pixel points of the three images obtain fusion pixel values. On the basis of this,the image edge feature points are segmented and grayscale processed to complete the architectural layout modeling. The experimental results show that this method has a good effect on building layout imaging,the accuracy of image space offset calculation is always over 80%,the image restoration degree is high,and it is close to the measured value,and the overall performance is better.
