| 摘 要： | 通过圆形靶标完成了单目二维视觉测量的摄像机标定.提出通过种子自增长法实现目标芯片ROI提取.通过质心计算获得芯片在运动过程中由于机械摩擦等缘故产生的平移量同时通过霍夫变换提取直线,从而得到运动不准产生的角度旋转.为视觉反馈控制提供了有效手段和自动编程器的实用提供了保证.

| Abstract: | Two-dimensional camera calibration is completed by use of Circular target.Algorithm of seeds of division is proposed to extract the ROI of the target chip.Through the algorithm of focus calculation,translation of the chip in the course of the campaign generated due to mechanical friction is obtained.While the angle of rotation is gotten by lines by means of the Hough transform.It provides effective means for the visual feedback control system and makes the automatic programmer practical |
