| Abstract: | 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. |
