Research of Ultrasonic Image Evaluation Based on Defect Dimension

Abstract:

Objective method of image quality evaluating is necessary for the research of ultrasonic imaging quality of different ultrasonic testing method, and deterministic calculation method is essential for the defect analyzing of ultrasonic image. Defect analyzing method of ultrasonic image is researched by threshold segmentation, noise point rejecting and area filling. Experiment results indicated that the defect position and size can be adjudged by the ultrasonic image.
