1.The characteristics of the coaxial and side visual sensing technologies and their state-of-the-arts of developments were summaried.
比较了目前激光焊接过程监测中常用的CCD和CMOS两种类型视觉传感器的性能,介绍了激光焊接过程视觉传感技术的难题及其解决方案以及常用的成像信号提取光路,综述了激光焊接过程同轴和旁轴视觉传感技术的各自特点以及国内外在这方面的研究现状。
2.To simulate this process,a double-side visual sensing system was established for observing weld pool in pulsed gas metal arc welding(P-GMAW).
视觉是手工焊接最重要的信息获取手段,为了模拟这一过程,建立了一套脉冲熔化极气体保护焊(P-GMAW)的双面实时视觉传感系统.利用被动光源视觉传感方法,研究了P-GMAW正反面熔池成像的滤光方法、成像时间、成像机理.结果表明,利用中心波长为665nm的窄带滤光片在脉冲基值结束期间取像,可以获取清晰的P-GMAW正面熔池图像;利用中性减光技术,可以获取清晰的反面熔池图像.分析表明,正反面成像的主要光源均来自于熔池的自身辐射,因此,成像质量可靠.针对不同的熔池图像特征,提出了相应的图像处理算法,实现了正反面熔池边界的提取
3.The passive visual sensing method was successfully applied to detect the image of weld pool in CO2 welding.
