摘　　要：结构光视觉传感器是焊缝跟踪系统中的重要组成部分,通过建立结构光视觉传感器的数学模型,确定像面坐标与空间焊缝位置坐标的对应关系。在确定模型结构基础上,分析影响结构光视觉传感器测量误差的因素,分析了传感器的结构参数对测量误差的影响关系,提出结构光视觉传感器的优化设计方法,依据仿真结果判定影响结构光视觉传感器的最优结构参数,并通过实例求出其最优解。Structured-light visual sensor is an important part of seam tracking system. In establishing the mathematical model of structured-light visual sensor,the relationship between the images coordinates and the spatial coordinates of the seam position are determined. Based on the structure of the model, in order to improve the accuracy, the factors influencing the measurement error structure-light visual sensor are analyzed. The relationship between structure parameters influence the sensor on measuring error has been determined. And put h^rward the optimization design method of structured-light visual sensor. Simulation results based on structured light visual sensor deterulines affect the optimal structure parameters, and find the optimal solution by examples.
