Defect-oriented ultrasonic three-dimensional imaging method

Ultrasonic 3D imaging technology is helpful to visually display the shape and distribution of defects, but when the amount of ultrasonic data is large, the 3D imaging reconstruction of non-defect parts waste computer performance, resulting in slow imaging speed. According to the sparseness of the mapped volume data, a moving cube algorithm based on bounding box is proposed for 3D reconstruction. The above algorithm was verified by experiments. The experimental results show that the improved moving cube algorithm can improve the time of reducing the three-dimensional imaging of ultrasound and improve the drawing speed.
