摘要： 图像的边缘是图像最基本也是最重要的特征之一。边缘检测一直是计算机视觉和图像处理领域的经典研究课题之一，在精确制导武器中有着广泛的运用。针对经典边缘检测方法在阈值选取中存在的问题，在分析几种二值化阈值选取方法的基础上，提出了自适应的边缘测检方法。基于C++Builder语言，研究了该方法的设计并得到了实现。通过实验验证，说明了该文方法的实用性和有效性。

Abstract: Edge is one of the most fundamental and significant features. Edge detection is always one of the most classical studying projects of computer vision and image processing field. It is widely applied to precise guide weapons. Aiming at the problem of the image-binary threshold selection in edge detection and based on the analysis of threshold selection methods, an adaptive edge detection approach is presented. The approach is implemented by C++ Builder programming language. Through experiment, the practicability and efficiency of the approach is demonstrated.
