用线阵CCD传感器获取大视场两维焊缝跟踪信息的研究

Study of Getting Two Demension Large Scale Tracking Information With Liner CCD Sensor

通过调整传感器光学角度和线阵CCD光敏元位置的特殊布置,以及特殊照明光斑形状设计,成功地用线阵CCD传感获取了大视场的两维焊缝跟踪信息。该传感器不仅适用于V型坡口、U型坡口、电弧气刨坡口及不开坡口的对缝;还适用于搭接接头和角焊缝。另外,本文还通过对各种焊缝图象特征的分析,给出了两维偏差及错边量的计算方法。

Through adjusting the sensor optical anglear and position of liner CCD and special shap of facula, the liner CCD sensor can get large scale two demension tracking information. This sensor can be used for tracking V-joint, U-joint and T-joint. Through analysed the various joint fingure sample. The caculation mathod of two demension difference and jagged edges is given.
