The invention provides an automatic focus searching method for pathological images under a microscope. The automatic focus searching method comprises the steps: arranging equipment and an acquisitionobject; adjusting the acquisition position of an image; roughly positioning a pathological image; and carrying out fine focus searching on the pathological image to obtain a final focus position. According to the automatic focus searching method, a preliminary positioning process and a fine positioning process exist, the step-by-step cleaning process of focus searching is met, meanwhile, operationis conducted through a definition algorithm in the preliminary positioning process and the fine positioning process, and the accuracy of automatic focus searching is improved under the condition thatthe processing speed is not affected. 本发明提供一种用于显微镜下病理图像的自动寻焦方法，包括：布置设备和采集对象；调整图像的采集位置；病理图像的粗定位；病理图像的细寻焦，获得最终的焦点位置。本发明的自动寻焦方法存在一个初步定位和细定位的过程，这符合了寻焦的逐步清洗过程，同时在初步定位和细定位过程中均通过清晰度算法来进行运算，在不影响处理速度的情况下提升了自动寻焦的准确性。
