摘要
针对手动检测中存在检测精度低、人为因素对检测结果影响大、检测结果不直观等问题,采用超声脉冲反射法,开展基于高速摄像识别定位的手动超声可视化检测技术研究,实现高速图像传输、识别定位、C扫描显示软件研制,构建手动超声可视化检测系统平台,利用碳纤维增强树脂基复合材料(CFRP)试样进行验证。结果表明:该系统图像处理速度较快,检测速度可达200 mm/s;该系统检测精度较高,可检出CFRP试样中Φ2 mm以上大小的缺陷,横向位置分辨力约为1 mm;该系统操作性强,适用广泛,结果准确,可靠和直观。
To address issues such as low detection accuracy,significant influence of human factors on detection results,and lack of intuitiveness in detection outcomes in manual inspection,this study employs ultrasonic pulse reflection technology to develop a manual ultrasonic visualization inspection technique based on high-speed camera recognition and localization.The research focuses on achieving high-speed image transmission,recognition and localization,and the development of C-scan display software,thereby establishing a manual ultrasonic visualization inspection system platform.The system is validated using carbon fiber-reinforced polymer(CFRP)specimens.The results indicate that the system has a fast image processing speed,with a detection speed of up to 200 mm/s;the system has high detection accuracy,capable of detecting defects larger thanΦ2 mm in CFRP specimens,with a lateral position resolution of approximately 1 mm;the system is highly operable,widely applicable,and provides accurate,reliable,and intuitive results.
