The invention relates to the technical field of image processing, in particular to a pericardial region positioning method, device and system based on feature analysis, and the method comprises the steps: firstly obtaining a group of CT sequence images which comprise pericardial samples of at least one heartbeat period; extracting an edge contour of each CT image in the CT sequence image to obtaina group of edge contours; fusing the group of edge contours to obtain a typical contour, and obtaining a deviation range of the typical contour; and finally, using the typical contour as the positioned pericardium area, using the deviation range as the heartbeat interval of the heart. The invention further correspondingly provides a pericardium area positioning device and system based on featureanalysis, and the pericardium area positioning accuracy can be improved. 本发明涉及图像处理技术领域，具体涉及一种基于特征分析的心包区域定位方法、装置及系统，所述方法为：首先获取一组CT序列图像，该CT序列图像包含对至少一个心跳周期的心包采样；接着提取该CT序列图像中每一张CT图像的边缘轮廓，得到一组边缘轮廓；进而将该组边缘轮廓进行融合，得到一张典型轮廓，获取该典型轮廓的偏差范
