Systems and methods generate a 3D model of a surface of an object immersed in a transparent liquid within a stationary cylindrical transparent tank. First and second laser line projectors and a camera are rotated around a central axis of the cylindrical tank. The first and second laser line projectors each generate a laser line perpendicular to a plane or rotation and aligned with the center of rotation. The camera images the object. An image from the camera is captured at each of several angular positions of the camera relative to a reference position of the stationary cylindrical tank. The captured images are processed to determine, for each laser line within each image, a plurality of 3D positions where the laser line is incident upon a surface of the object. In embodiments, images are corrected with ray tracing or image warping and registration functions.
