针对高温工程结构测量问题，将图像处理中的边缘特征检测技术应用到高温结构测量中，提出一种基于Canny边缘检测和 Hough 变换算法的高温结构测量方法，解决了高温结构测量的实际需求。该方法先对试件结构测量位置进行边缘检测和提取，并以分段直线形式确定待测边缘，再计算得到宽度等结构测量结果，并将其转换为材料力学性能参数。该方法充分利用了图像处理技术的优点，测量条件低且环境适应性强，同时采用分段检测的优化设计，测量精度高，稳定性好。

According to the actual engineering requirements,the feature detection technology for image edge in image processing was applied to structure measurement at a high temperature.The high-temperature structural measurement method based on Canny edge detection and Hough transform algorithm was proposed. Based on the edge detection and extraction, the specimen structure is measured,which takes the form of piecewise linear representation.Then the width of the structure is obtained and it is converted into a mechanical performance parameter.This method takes advantages of image processing technology and needs low measurement conditions and has a good environmental adaptability.In addition,it adopts the optimization design of segment detection,with a high accuracy and good stability.
