基于激光标定的热工缺陷面积测量方法

针对建筑外墙热工区域缺陷面积的测量难题,提出了一种利用激光标定和热成像技术探测热工区域,从而进行图片处理计算面积的方法。该方法使用红外热像仪器采集目标图像,并由Matlab设计相关算法,首先将目标图像转换成YCbCr色彩模型,然后进行灰度处理,二值化目标图像,最后利用激光标定对目标的面积进行计算。为了验证其有效性,通过实体工程的运用,证明该方法具有方便快捷、准确度高的优点。

Method for Measuring Thermodynamic Disfigurement Area Based onLaser Calibration

For the difficulties in measuring the defect area of building external wall thermal region, this paper proposed a method, which utilized laser calibration and thermal imaging technology to detect the thermal area and then processed the images to calculate area. The method used the infrared thermal image instrument to collect target image, and the relevant algorithm was designed by Matlab. First, this paper converted target image to YCbCr color model, then grayed and carried out the image binary, finally this paper used laser calibration to calculate the area of the target. In order to verify the effectiveness of the method, the method has advantages of convenience high accuracy through the application of substantial project.
