The invention discloses a three-dimensional perspective imaging technology of ultrasonic microscopy, comprising the following steps of: when a computer three-dimensional imaging technology is applied to the ultrasonic microscopy, processing full wave data acquired by ultrasonic microscopy scanning, and building a three-dimensional mathematic model; layering the data in a matrix of the mathematic model by a computer three-dimensional image engine, rendering color for each layer of data according to the amplitude in the mathematic model, and setting transparency, and then arranging each layer of image according to a Z coordinate to form a three-dimensional perspective multi-layer rendering model. The three-dimensional perspective imaging technology can be used for visually displaying the internal structure and defects of a tested workpiece, and realizing the rotation and zoom functions of a three-dimensional graph; when a section is specified, the technology can be used for partially drawing the data in the thr
