提出了一种基于积分投影技术的抗噪声数字图像位移测量算法.首先通过对相关图像做灰度投影形成水平和垂直方向上的积分投影矢量,并将其应用于基于差值函数的一维平移检测技术,以求取图像二维平移矢量.实验证明与传统相相关法和模板匹配法相比,该算法在保持同等级准确率的同时保持了灰度投影算法计算时间上的优越性能,并具有良好的鲁棒性.

A novel image displacement measurement approach is proposed. By utilizing grayscale integral projection along row and column direction, projection vectors reflecting translation information are obtained and then applied to difference function-based shift detecting process for displacement measurement. Experimentally, this method shows high performance and robustness with less time consuming compared with traditional phase correlation method and template matching method.
