摘　　要：针对传统的钢架支护形变检测方法检测准确度低的情况,设计了一种基于点目标分析的异型立体雕塑钢架支护形变检测方法。使用点目标分析技术处理对事件序列上的点目标进行干涉相位处理,并对钢架支护的不同测点进行数字模拟,以提取异型立体雕塑钢架支护形变特征,由于提取的钢架支护形变特征会受到外界因素的影响,在第二步进行优化处理。引入测量误差随机变量描述钢架支护形变的不确定性,并结合灰度阈值的取值设定最优阈值,在此基础上,检测形变边缘,更加精确形变信息,以此完成了基于点目标分析的异型立体雕塑钢架支护形变检测方法的研究。实验对比结果表明,此次设计的基于点目标分析的异型立体雕塑钢架支护形变检测方法比传统检测方法准确度高,能够在外界因素影响下更准确地测量钢架支护形变情况。Aiming at the low accuracy of traditional deformation detection method for steel frame support,a deformation detection method for special-shaped three-dimensional sculpture steel frame support based on point target analysis is designed.The point target analysis technology is used to process the interference phase of point target on event sequence,and the different measuring points of steel support are simulated numerically to extract the deformation characteristics of special-shaped three-dimensional sculpture steel support.Because the extracted deformation characteristics of steel support will be affected by external factors,the second step is optimized.The uncertainty of steel frame support deformation is described by measuring error random variable,and the optimal threshold is set by combining the gray threshold value.On this basis,the deformation edge is detected and the deformation information is more accurate.Based on this,the research of deformation detection method of special-shaped three-dimensional sculpture steel frame support based on point target analysis is completed.The experimental results show that the deformation detection method based on point target analysis is more accurate than the traditional method,and it can measure the deformation of steel support more accurately under the influence of external factors.
