摘要
在透视投影和坐标变换的基础上,建立测头成像视觉三坐标测量系统的数学模型;求解了共线、共面和空间三种点阵式测头构成的系统模型,以最简单的共线三点型点阵测头为例建立实测视觉坐标测量系统,实验结果证明系统模型的正确性。
In terms of perspective projection and coordinates transformation, the mathematical model is proposed for a vision 3D coordinates measuring system using an n - point probe. The different solution of model is discussed using collinear, coplanar or spatial n - point probe. As a representative example, the vision coordinate measuring system is set up with a collinear 3 -point probe. The experimental results have shown that the system model is available.
