一种基于单幅图像双消失点的摄像机标定方法

A Camera Calibration Method Based on Two Vanishing Points in a Single Image

介绍了摄像机标定的概念和两种经典方法。针对不同的视觉任务要求,提出了一种基于单幅图像双消失点的摄像机标定方法。首先对图像进行一些合理的假设。如图像包含两个消失点、图像中心为摄像机在投影面上的投影中心。通过实验仿真验证,此方法在对摄像机标定精度要求不高的情况下,可以很方便的求解摄像机的参数。

After introducing the concept of camera calibration and two classics methods, a camera calibration method is proposed based on two vanishing points in a single image, aiming at a different visual task. It firstly ad- vanced some reasonable assumptions. Such as the image contains two vanishing points, the image center is the or- thogonal projection of the center of projection of the camera onto the screen plane. Experiments show that the cali- bration method could easily get the camera＇ s parameters, in the case of the precision is not so high.
