摘要
对电弧光的干扰进行了深入的研究,建立了电弧干扰的光照模型;依据透视变换理论,给出了光源倾斜照射和摄像机倾斜接收情况下,被检测物体与摄像机之间的一般坐标变换数学模型。这两个模型对结构光传感器的设计具有非常重要的指导意义,基于这两个模型设计的结构光传感已在自动焊接实验中获得了成功的应用。
Abstract
The influence of arc noise to laser strip image is studied comprehensively, and the arc noise model is established. Originating from the principles of projective and perspective transformation, the models of coordinate transformation between workpiece and camera with arbitrary angle of laser light and camera are presented. Both of the models are very useful to the design of structure light sensor. The sensor designed based on the theory above is used in automatic welding.
