A tracheal model reconstruction method using the ultrasonic and deep-learning techniques； which comprises the following steps: obtaining the image and position information of the tracheal wall, positioning the graph-information space, processing image, extracting the image-feature and recognizing the image using deep-learning, positioning the 6 DoF space, calibrating the image-space, converting the image-space, and forming a three-dimensional trachea model. Thereby, providing a tracheal model reconstruction method that can correctly and quickly reconstruct and record a stereoscopic three-dimensional tracheal model.
