description The invention belongs to the technical field of ultrasonic imaging, and particularly relates to a robust adaptive frame correlation method and system based on an image pyramid, and the method comprises the following steps: S1, constructing a pyramid according to a noise image; s2, calculating a frame correlation coefficient template according to the top image of the pyramid; s3, performing scale transformation according to the coefficient template; and s4, achieving frame correlation processing of the noise image according to the coefficient template after scale transformation. According to the method and system, the frame correlation coefficient is calculated through the pyramid top layer image, so that the complexity of the algorithm can be greatly reduced; in the construction process of each layer of image of the pyramid, convolution kernel smoothing is carried out, so that the image pyramid has a good denoising effect. 本发明属于超声成像技术领域，具体涉及一种基于图像金字塔的鲁棒自适应帧相关方法及系统，其中，涉及的一种基于图像金字塔的鲁棒自适应帧相关方法，包括以下步骤：S1、根据噪声图像构建
