The invention relates to an organ sketching method and device, a computer device and a storage medium. The method comprises the following steps: inputting a to-be-processed medical image into a firstdeep convolutional neural network to obtain a target area image, and inputting the target area image into a second deep convolutional neural network to obtain an initial segmented image; and obtainingan organ sketching result based on the initial segmentation image. In the organ sketching method and device, a computer device and a storage medium, a deep learning model is adopted, a universal framework is established, different types of organs can be effectively and automatically sketched, consumed time is short, adaptability is high, efficiency is high, meanwhile, a target area is located firstly, then the target organ is segmented, and a segmentation result obtained within a small range is more accurate and higher in accuracy.
