| 摘 要： | 在高精度尺寸测量系统中,采用传统短焦距定焦光学方法时径向畸变较大,影响测量精度.为提高测量的精度,根据摄像机针孔成像的线性模型和镜头的非线性模型,建立摄像机定焦镜头的对焦数学模型,提出了采用交比不变的标定方法.研究了物体远近的小范围变化对测量结果准确度的影响,修正了标定的像素当量;分析了镜头的几何投影变换关系,标定了镜...

| Abstract: | In high-precision size measurement system,the traditional method using short-focus fixed focal length lens has large radial distortion that may affect the measurement accuracy.In order to improve the accuracy of the measurement system,a focusing model of fixed-focus lens of camera was established and cross-ratio invariant calibration method was proposed according to the linear imaging model of pinhole camera and the non-linear model of lens.The impact of small objective distance changes on measurement accur... |
