【摘要】 水下焊缝跟踪中水的折射对传感器的设计有着重要的影响。文中讨论了水下焊缝结构光传感器的内部布局,在此基础上通过计算得出了激光器放置的角度和位置,并且分析了水体和玻璃折射对焊缝位置测量造成的影响。通过实例计算,得出了在CCD近轴附近区域焊缝测量基本不受影响的结论。更多还原

【Abstract】 he refraction of water has an important impact to the design of the structured-light sensor used in welding seam tracking underwater.The internal layout of the laser structured-light sensor has been discussed,and laser’s angle and position have been calculated.Further more,an conclusion has been reached that measurement held around CCD adaxial area is basically not affected by analyzing the water and glass refraction’s effect for the CCD measuring the wielding position through computing an instance.更多还原
