摘要
图像测量技术是近年来在测量领域中形成的新的测量技术。在图像测量方法中,精确地确定图像的边缘位置极为重要。本文首先简要对图像测量系统进行阐述后,着重对图像边缘特征进行分析,并指出,边缘特征点处斜率最大,从而为实现亚象元边缘检测提供了理论依据。
The technology of image measurement is a newly rising technology in the domain of the measurement recent year.It is very important to locate the position of image edge precisely using the method of image measurement.First,in this paper,we describe briefly the image measuring system,then analyze the characteristic of image edge and point out the gradient is the maximum at the characteristic points of edge.This provides the theoretic foundation for subpixel edge detection.
