摘　　要：为了有效地解决传统摄像机标定方法独立性差、附加条件繁琐的问题,提出一种基于非线性三角函数转换的摄像机标定方法。该方法无需设立参照系,仅根据摄像机架设信息,利用图像空域内的三角坐标换算、构建不同纬度之间的非线性转换模型,并通过畸变过滤手段来确定摄像机采集图像中选取点位的实际场景对应坐标,同时不降低标定的准确率。实验结果表明,该方法可以在无参考物的条件下准确的对图像进行点位标定。To solve the independence non-exactness problem and the complicated additional conditions of the traditional camera calibration effectively,a new method based on non-linear trigonometric conversion by getting the camera internal parameters and external parameters is proposed.This method does not need to establish frames of reference,it can determine the corresponding coordinates of the actual scene position of the point which is selected in the camera just bases on the camera set up information,leaching aberrance method and establishing the non-linear transition model ground on trigonometric function conversion,which doesn＇t reduce the calibration accuracy.Experiments show that the proposed methods could provide the accurate calibration of the image point position without frames of reference.
