摘要
研究了数码相机的内方位元素检测和镜头畸变差校正 ,应用近景摄影测量的原理与方法 ,提出了一种基于立体像对无物方控制的物体表面 3维模型信息快速获取方法 ,试验表明 ,该方法获取 3维信息速度快、精度较高。同时文中还比较了可变焦数码相机和固定焦距相机在获取 3维信息精度方面的差异。
The paper studies the method of verifying of digital camera's inner orient elements and the correction of Lens Distortion. Using the theory and means of close-range photogrammetry, it presents a method of obtainning the 3-Dimension information of the objects surface fast based on stereo pair with no control point. The test shows the precision is high, and the speed is rapid. At the same time, the paper has the comparative study on the precision by zoom digita camera with fixed digita camera, and has some useful conclusion.
