Description

technical field [0001] The invention relates to the technical field of phased array ultrasonic imaging non-destructive testing, in particular to an imaging processing method, equipment and a computer-readable storage medium. Background technique [0002] Phased array ultrasonic imaging detection is based on the scanning imaging detection of linear, surface, circular and other types of ultrasonic arrays under the set focal law. In the scanning method, sector scanning (S-scan) and electronic scanning (E-scan) are commonly used to scan and image metal materials such as welds and forgings, composite materials, and non-metallic materials such as glass fiber reinforced plastics to obtain imaging inspection pictures. During phased array array ultrasonic sector scanning and electronic scanning imaging testing, it is necessary to perform partitioned focusing testing on different thicknesses or different regions of the same target workpiece. figure 1 Schematic diagram of the detectio...

Problems solved by technology

Interpreters interpret multiple imaging inspection pictures to complete the evaluation of the target workpiece, which is not only a heavy workload, but also low efficiency

[0006] 2. When the target workpiece itself contains defects with large height and large inclination angle, such as cracks, unfused and other planar defects, the target workpiece is inspected in partitions, and multiple imaging detection maps are obtained, corresponding to each partition The imaging inspection chart cannot fully present the defect form, which leads to misjudgment by defect interpreters

[0007] 3. Due to the limitation of the size of the array probe itself, the imaging detection map generated during the detection of a limited fixed position of the target workpiece cannot completely present the defect form, which leads to misjudgment by the defect interpreter
