The invention provides an unmanned underwater vehicle for marine topographic surveying and mapping, and relates to the technical field of marine surveying and mapping, the unmanned underwater vehicle comprises an underwater cabin body and a first surveying and mapping device, the underwater cabin body is rotatably connected with a mounting seat, the mounting seat is rotatably connected with a mounting sleeve, the mounting sleeve is connected with a calibration mechanism, and the calibration mechanism is connected with the first surveying and mapping device. The calibration mechanism comprises a second surveying and mapping device and a reference reflection block, a calibration motor is fixed to the mounting sleeve and connected with a calibration lead screw, the reference reflection block is in threaded connection to the calibration lead screw and connected with a displacement sensor, rotating rods are arranged on the two sides of the mounting sleeve, and the displacement sensor is connected with the rotating rods. The rotating rod is connected with a reference mechanism, the reference mechanism comprises a reference torsion spring, a pressure sensor and a reference seat, one end of the reference torsion spring is fixed on the rotating rod, and the other end of the reference torsion spring is connected to the pressure sensor. By arranging the calibration mechanism, the propagation speed of sound waves is determined in real time, so that the surveying and mapping distance calculation is more accurate.
