The invention discloses a method for measuring a wedge-shaped body angle on the basis of laser scanning and sound wave velocity. The method comprises the following steps that: establishing an ultrasonic wave front model generated by laser scanning on a cuboid boundary line; according to the ultrasonic wave front of the cuboid, obtaining a mathematical expression of wave velocity and laser scanningvelocity; according to the mathematical expression, distinguishing transverse waves and longitudinal waves in the ultrasonic wave front of the wedge-shaped body; according to the transverse waves andthe longitudinal waves, establishing the ultrasonic wave front model generated by the corresponding laser scanning on the boundary line of the wedge-shaped body; and according to the ultrasonic wavefront model of the wedge-shaped body and a similar triangle principle, calculating a wedge-shaped angle. By use of the method, through an indirect method, the degree of the wedge-shaped body dip anglecan be effectively and quickly obtained, and errors are reduced.
